HTML5 Audio Issue Workarounds

I have spent the better part of a week working on problems with a project played back fine in Flash but had audio problems with HTML5. Here are some of the issues and workarounds I came up with:
Custom buttons muting audio
The playbar buttons are too small for smartphones and most tablets so I created larger navigation buttons. Unfortunately, the audio would mute whenever I used the TOC and CC buttons.
Created user variable currentFrame
"Assign currentFrame with cpInfoCurrentFrame" at beginning of button Advanced Action
"Assign cpCmndGoToFrameAndResume with currentFrame" as last action.
iOS devices repeating audio from first slide after a "Loading..." of other slides
Made the audio files as small as possible (use 32kbps as Audio Preference). Be sure to record as WAV and make this a publish preference to minimize audio artifacts.
Delayed audio start time at least 200-300 ms from slide start. I had originally added silence to the beinning of all my files so CC would appear from beginning of slide. Deleting the silence and delaying the audio minimized "Loading..." and eliminated the first audio repeat problem.
Placed end of mouse movements outside of audio content to avoid iOS dual audio file issue.
MobilePlaybar lacking TOC and CC buttons
This one's actually another way around the audio muting problem. I initially didn't use the MobilePlaybar becasue of it not having TOC and CC buttons. I prefer having the Playbar outside of the content area so I went with a modified MobilePlaybar.
Created TOC.png and CC.png. Added to assets\playbar\PlaybarIcons.
Edited assets\playbar\playbarScript.js
     Replaced 'Exit' in playbarAssetArr = with 'CC' and 'TOC'
     Changed var left = 8; to var left = 9;
\assets\js\CPPlaybar.js already has CC and TOC code so does not need to be modified.
I have one last issue that others may have an answer for. The MobilePlatbar Back and Forward buttons don't always work with i iOS. Any ideas?

Hi there,
same issue here.
A workaround, far from perfect, is to request the base64 encoded data using an Ajax call
and set the src attribute of the audio element to 'data:audio/mpeg;base64,' + base64encodedaudio.

Captivate 7 - HTML5 audio/slides not syncing

Hi,
I am trying to publish out to HTML5 (Captivate 7 with the patch on Windows 7). I have audio on each slide and if I just let it run straight through, it's fine. However, if I page forward the audio is not sync'd with the slide anymore. It looks like it take a little longer for the slide to catch up but the audio starts right away.
Also, if I go back and forth (I know this isn't right but I know learners are going to), sometimes I get audio from two slides playing at once.
Is this just an HTML5/audio issue or is this a Captivate issue?
Thanks,
Joy

Sreekanth,
I think I've found a workaround for this issue. I’m finding when audio is placed on each question slide in the pool, the audio on subsequent slides play. The audio on the question slides has to be different from audio used on non-question slides (but all the question slides can use the same audio). Also, the question slide audio can be a very short and silent piece of audio, so nothing is heard on the question slide itself.

HTML5 Audio Playback issue from firefox 33 and above.

I have created an application which was working just fine till firefox 32. It is still working fine in firefox 32. But from firefox 33 and above, the audio playback does not start intermittently.
I tried to debug and find the problem further. What I observed is that the html5 audio element in firefox 33 and above does not dispatch 'readyState' event as 4 which is needed to start the playback. It shows its value as '2' due to which, the 'canplay' event is not getting triggered.
This issue is replicable on local machine as well using some bandwidth throttling software. Also, it is important to note that this issue is visible on MAC's firefox. On windows, things are working just fine.
If anyone has any solution of this problem, please let me know.

Actually, I ran all but ADW and I included Super AntiSpyware. There is no virus. It is only V33+ and other browsers work fine. I think I will give up on Firefox for now until I upgrade to Win 7.
Thank you everyone for your input.

Play() method not implemented HTML5 audio tag?

Hello,
I am trying to play a sound using the HTML5 audio-tag and Adobe Air SDK 2.5.
This is part of the HTML5 code:
    <audio preload="auto" id="myTone">
        <source src="test.mp3">
        <source src="test.ogg">
    </audio>
And from javascript I do:
    a = document.getElementById("myTone");
    a.play();
Unfortunately, that doesn't work. I get this error message in the console window:
    TypeError: Result of expression 'a.play' [undefined] is not a function.
However, when I run this code directly in Firefox 3.6.11 on my Windows XP machine, it works.
Dito in Safari 3.2.1 on my Mac OS 10.5.6 computer.
So apparantly, not all methods and events of the audio-tag are implemented in the Adobe AIR environment.
Is this by design? Or is it a bug?
I know there is another way to play sounds (I read Jeff Swartz' article - http://www.adobe.com/devnet/air/ajax/quickstart/articles/sound_in_html.html). But I think a pure HTML5 solution would be cleaner.
Who can provide more info about this issue?
Many thanks.

I am using ALSA and Icecat. When I play any html5 audio/video it works, but the next time i click on another audio/video link I lose sound.

I am using Parabola (a fork of archlinux), Icecat 31.4 and ALSA
Icecat and firefox seem to hold onto the soundcard when I click on a new html5 audio/video link in the same tab. The next video/audio element loses sound. If I wait 10 seconds and click back to the start of the audio/video, the audio returns. I often get cpu spikes for icecat when it happens.
I have tried this with both motherboard and usb sound and I get the same problem. I have disabled extensions (addons) in Icecat, deleted profiles, reinstalled the browser and even installed firefox from the AUR and it still occurs.
I have disable gstreamer in about:config and restarted and it still occurs.
My .asoundrc is this:
pcm.!default {
type plug
slave.pcm "hw:0,0"
All my other audio applications work. I have noticed that if I use pulseaudio it fixes it, but it should work without anyway, like it used to. I think something happened after an update, but I'm not sure.
Any help would be appreciated. I know it's not a big problem, but it's really frustrating and I've had it for ages. I even switched browsers to get away from it.

*nerding out*
I am not an expert in this and if we get stuck I have found a mailing list for the alsa project that can be contacted: http://www.alsa-project.org/main/index.php/Mailing-lists
Gstreamer is disabled in Firefox as well as the os?
Since you are seeing issues with ogg files and moving video/audio combination I started to dig into file formats {sox http://sox.sourceforge.net/soxformat.html}
For ogg would the file format affect the "raw"?
defaults.pcm.file_format "raw"
Updated libraries
alsa-lib-1.0.6-8.FC3
alsa-utils-1.0.6-3
No no, here:

IMovie audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !

iMovie 11 audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !
I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

I have a fix - or rather, a workaround.
WARNING: It is lengthy, but still far better than starting a new project from scratch.
I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
This will require:
A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too, as they will be extremely helpful later.
4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
6.) Once you are done with this, export your newly pieced together audio track.
7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
YOU'RE FINALLY DONE!!!
I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
DON'T USE IMOVIE EVER AGAIN.
I hope this helped!

Html5 audio doesn't work for mp3s.

I can't seem to get tag <audio> working with mp3s on my system(FF 24, Win 7 x64). I tried some wav files, those work ok. But whenever i try to play mp3 file, the html5 player just flashes for a few milliseconds and then disappears. So, is there a bitrate limitation (or any other limitation) for html5 audio tag on mp3s?
Here's an example of code and one of the mp3 files I am trying to use - http://dindo.wz.cz/jukebox.html .
(file http://dindo.wz.cz/Galaxy32Star4.mp3 )
The console (ctrl+shift+k) gives these errors (rough translation):
[14:07:48.861] Type HTTP "Content-Type" "audio/mpeg" is not supported. Loading of media http://dindo.wz.cz/Galaxy32Star4.mp3 has failed. @ http://dindo.wz.cz/jukebox.html
[14:07:48.862] Couldn't load any of candidate sources. Loading of media was suspended. @ http://dindo.wz.cz/jukebox.html
p.s: Even the w3c example doesn't work when i remove the ogg source. (http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all).

can you replicate the issue, when you create a new profile for testing purposes?: [[Use the Profile Manager to create and remove Firefox profiles]]

HTML5 Audio/Video Not working at all on new Windows 7 install

I'm the developer of jPlayer, a plugin for jQuery and my recent testing a new laptop on Windows 7 Ultimate, Safari 5.0.1 found that the audio and video HTML5 elements do not work at all.
http://www.happyworm.com/jquery/jplayer/
http://www.happyworm.com/jquery/jplayer/HTML5.Audio.Support/
My plugin checks for the mediaElement.canPlayType() method and if it exists it then checks the suitable MIME types for compatibility. But that is just the fine details. Basically, the Safari 5.0.1 browser installed on Windows 7, without any of the audio or video support.
Testing on other sites around the web also showed that this install did not include those parts of the HTML5 spec. No idea why. I installed it off the apple/safari site and it is fully updated. Chrome 5, Firefox 3.6, Opera 10.6 all worked fine.
Example of other sites used to check:
http://www.html5rocks.com/tutorials/video/basics/
By comparison, my old Windows XP machine works fine with Safari 5.0.1 and has had a version of safari installed on the machine since Safari 3.
Side note, the Mac versions of all the browsers work fine. Also the iPad emulator shows everything works.
Any ideas what went wrong with my install on Windows 7?
Best regards,
Mark P

I am looking at this issue too. I installed Safari 5.0.1 on Windows XP on two different machines. In these cases I found that the .canPlayType() always returns undefined on an audio element. So http://www.happyworm.com/jquery/jplayer/HTML5.Audio.Support/ showed that no support for HTML5 audio was found. ( http://twitpic.com/2f16nh )
Both installations were clean installs and it was also the first time Safari had been installed on both XP installations.
I don't see these issues on OSX 10.6.4 and others have reported that it worked under Windows 7. My guess then is that is something to do with new installs and not OS.

Safari HTML5 Audio Bug

Hello,
With Safari, it is not possible for me to play HTML5-Audio. I've tried it on several demo sites, but always the same.
e.g. http://demos.w3avenue.com/html5-unleashed-tips-tricks-and-techniques/sample-04-a udio-demo.html
The demo page from Apple also does not work -> http://www.apple.com/html5/showcase/audio/
Safari 5.0.3
Windows 7
Does anyone have the same problems?

Hi,
It's actually a web application i.e. it runs as a series of web pages from a URI. That said, it sizes itself dynamically to render on different devices and is designed to be run on any web browser (mobile or otherwise) on any device. However, I'm encountering issues with mobile browsers (not just Apple I might add) that will not allow preloading of HTML5 audio even if they're on a WiFi connection. I will have to re-think my design and perhaps develop a stand-alone App rather than a web page using similar technologies.

Html5 audio duration problem

Hi guys,
I'm building a website using the HTML5 audio control. I'm having quite a trouble with certain mp3 files: it simply doesn't seek correctly when moving the slider. Specifically, I can move the slider to the desired position, but the sound jumps to an incorrect time. Therefore, when the slider comes to the end, the song is already playing, and the current time keeps incrementing.
In addition, the track length (it's supposed to be a fixed value, loaded from the metadata) has a strange behavior given that point: it starts incrementing as the current time...
I found no differences between the files that work correctly and the files that don't, but I suspect is a browser support related issue, since I didn't experience that problem using Chrome.
Just in case, you can download the file here:
http://www.4shared.com/mp3/JzSPjx3Qba/Quartet_12_Mov_1.html
And this is the test code I'm using:
<!DOCTYPE html>
<html>
<head>
<title>Test Page</title>
</head>
<body>
<audio controls="controls">
<source src="Quartet 12 Mov 1.mp3">
</audio>
</body>
</html>
Thanks in advance!

hello, if you think it's a browser issue, you can file a bug report at bugzilla.mozilla.org - there it should get the attention of mozilla's developers (whereas this forum is primarily staffed by volunteers and firefox users like you helping out).
thank you!

Outgoing call audio issue

I bought an iPhone 4s in India two days back. I am facing a strange problem when I make audio calls. Very often (not all the time) I do not hear any audio after making an outgoing call though the call go thru' and timer starts clicking. When I checked with the people whom I called, they said that they got the call but did not hear anything at their end. The workaround that I figured out is to press SPEAKER button twice (activate and deactivate) when I encouter this problem. It seems to be working as of now. Not sure if this is a hardware problem or a software problem or if I am missing anything with settings. Can someone help me?
Thanks !!!

Hi raj1434,
Thanks for visiting Apple Support Communities.
If you are not hearing callers, or being heard on calls, use these steps to guide your troubleshooting:
iPhone: Microphone issues
http://support.apple.com/kb/ts5183
Make sure nothing is plugged in to the jack connector.
Make sure nothing is blocking any of the microphones (see the pictures below to locate the microphones on your device)
Make sure none of the microphones is obstructed by dirt or debris.
Turn the iPhone off and then on.
Make sure that the latest version of iOS is installed.
iPhone: Receiver and call audio quality issues
http://support.apple.com/kb/ts5196
Increase the volume during the call.
Make sure nothing is blocking the receiver. If you're using a protective case or display film, remove it and try again.
Make sure nothing is plugged into the headphone jack or the dock connector.
Check the receiver opening to see if it is clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush.
Try another location with better signal. If the audio issue happens only when on a call, it could be due to the location.
If the iPhone is paired with a Bluetooth headset or a car kit, try turning off Bluetooth on your device. Learn more about troubleshooting Bluetooth connections.
If none of the steps above correct the behavior, back up your iPhone and restore the iOS software to factory settings:

Bootcamp 3.1 and imac windows 7 64bit update not installing. Audio issues!

After many days of work getting the windows 7 working in bootcamp in my imac 27 (still with audio issues) I eagerly awaited the bootcamp update and imac updates.
Neither will install.
Then I find that according to tech support as of now I have to reinstall Windows 7 again for the updates to work!
It took me 5 full 8 hours days to get all my scientific programs installed and working, now I find I can't even simply update the drivers I need. I don't want to reinstall.
My only issues are audio.
Here they are:
1) The headset jack works fine on the Mac side, but in Windows 7, it causes the i7 intel CPU to go crazy. There is no CPU spike on the mac side.
2) The headset jack in the imac is a trrs jack. The same as in the iphone, a tri-band jack that has three bands, two audio out channels and one mic in channel. A trrs headset works fine on the mac side with using the headset mic (as in iphone) rather than the built in mic. (this provides much better quality for sound recording). I don't want to use a usb mike.
In Windows 7 the mic part of the trrs headset does not work.
3) In Windows 7 when going into audio devices recording, no audio mixer shows up, so when I do video or audio screen capture the only way to capture the sound is through the speakers and then back through the imac built in mic, rather than directly through the unit. (terrible sound quality) On the mac side the mixer element works fine.
Now I find from other imac users that even the new updates for the imac on windows 7 don't address and fix the audio issues. I am sure not going to go through 5 more days work only to find the audio issues still don't work.
I need these audio aspects to work properly though!
I have tried to get drivers for the cirrus logic audio card, but guess what there are none available and cirrus logic doesn't even recognize the board or offer drivers.
I have many windows programs I must have for my scientific research!I bought the top of the line Imac with all the bells and whistles because Apple promised that the machine could run Windows 7 in bootcamp natively!
It doesn't. This has been a nightmare of problems.
Is Apple going to step up to the plate and make good on their promises?
Does any one have a fix for any of the audio issues, or know how to install the new drivers without a complete reinstall of Windows?
Installing a few sound drivers and software should not require a complete reinstall. Getting the proper drivers for the headset jack audio in and audio out jack should be the most basic of fixes. Making the audio mixer work should be elementary.
If you are an Apple tech person or an Apple user that can help on these issues, please do!
Thanks, Dr. Duke
An American profesor in Europe.
PS I will post this under Imac windows 7 updates without a reinstall and under
imac Sound issues.

On another thread a few people have responded saying that their imac has the same situation, the cpu is going crazy and the imac gets hot with headphones or speakers plugged in. But this doesn't happen in the mac side.
If you have an late 2009 imac and don't have these audio issues, let us hear from you. If you don't, lay out the problem here.
Here is my last two cents in to the inquiry.
Not only does the cpu run crazy but the imac 27 gets very, very hot. Since I unplugged the headphones, it runs much, much cooler.
Certainly, some Mac engineers should take care of this problem, it seems it is universal on all the imac 27's and from what I gather, the smaller screened cousins too.
Also, we certainly want a stereo mix option for audio in or out, or what is called "what you hear" or wave out. Imac is supposed to be much geared to multimedia apps.
Finally, the mic jack part of the trrs set up MUST be fixed! A lot of manufacturers are going to headset combo jacks as they call them, mic in and stereo out on the same tribanded plug. But, the old single jack for mic in and single jack for stereo out are two tiny parts of the hardware and super inexpensive for the manufacturer. Why in the **** to go to the "advanced" triplug if the **** thing doesn't work.
Mac has a great reputation. I hope they remedy these problems right away.
Anyone whose imac 27 or 24 whose headset plug is working correctly. Let us know! I don't think anyone's is, but I think that few people understand that their cpu is running so much faster with the plug in, plus few even understand the combo jack and the triband, or trrs audio jack! Out of 4 audio technicians I talked to, not one of them knew what a trrs jack was or that you even have a mic in jack as part of the headset jack!
When I told one senior that it worked on the Mac side, he didn't believe for a while, thought my sound might be recorded from the onboard mic, but I proved it to him by tapping iaudibly on my iphone mic headset and and it showing up in garage band clearly and listening to big difference in audio.
As for a usb audio adapter, I am in a neon light environment and find that those adapters are more sensitive to electrical interference. Besides I want to use the headset jack as it was meant to be used!
Thats it.
Again, if anyone using an imac 27 and windows 7 64 or 32 doesnt have these problems, let us know! We are all anxious for a fix!
Best to all!

SoftPhone over VPN audio issue

Having a "one-way" audio issue when IPC connects over VPN to any Main Office IP Phones (7960). Remote IPC (softphone) shows "0 Received" Packets, but the IP Phone shows them as being sent.
This does NOT happen if IPC contacts another IPC on a PC at Main Site, or any kind of phone at the other branch offices.
Have looked at all of the audio settings on the VPN IPC unit, they are correct.
Any ideas?

Try to sniff the Ethernet traffic during call setup at the CallManager. When Callmanager sends Call Control messages to remote party, it could send wrong IP address or UDP port as an RTP parameters.
Another components could block the traffic are firewalls. How do you have your VPN tunnel built? Do you use Cisco VPN Client? What terminates your VPN traffic at the central location? PIX, VPN3000 or Router? Traffic may go one way without a change, and some protocol FixUp may be triggered for this traffic on the way back. If you have access to firewall logs, check if you have any traffic dropped.
Good luck,
Mike

Logic 9.1.8 & Mainstage 2 - crashing frequently/audio issues

I have just uprgraded to this set up (though using the same sound card as I did on my Mac Book with Logic 8 & Snow Leopard prevously) - in order to avoid overloading which was happening on my previousl set up.. only to find that this new system seems very buggy - crashes frequently on Logic (Sudden Motion Sensor error - have disabled that now) and Main Stage freezes. Then a wierd echoey sound can happen - whereby any audio is echoed back from DAW, in Logic AND Mainstage.
I have down loaded two plug-ins/VST's since starting to use this new set up - an XILS Lab L.E. verision and a Crystal synth. I've downloaded the up to date Duet drivers from Apogee. (I have an Duet 1.5 that I used with my old set).
Have looked at the Console system log to try and understand what might be happening - it is FULL of text on occasions when Logic crashes - I am not tech savvy enough to unpick it though.
If anyone has any suggestions to help I would be grateful, thanks.
I do wonder if it is a Core audio issue though - given the echoiing that seems to occur...

My Ipad 2 external speakers does not work and headphones has popping sound. This all occured at the same time as my Iphone and Ipod headphones only played mono (no, the "mono" option is not on). How can there be audio issue for all these devices?

My IPad 2 external speaker does not work and the original headphones have popping sound when used. This all occurred at the same time as my IPhone and IPod headphones only plays mono (and no, the "mono" option is not on) with the original headphones, as well as, other headphones tested. How can there be audio issue for all these devices at the same time?
As you may have noted from the list of Apple devices I own, I believed in the Apple and the products it was producing; but it is hard to believe from my experience and the other voices within the Apple Community that we are all experiencing the same hardware issues. Especially since I recently, I upgraded to an IPhone 4g (no, my faith in IPhone 5 series is very little) and is experiencing the same audio problem as described above. So now, I am off to the Apple store again to be told that it’s a hardware problem on new IPhone. Really? Apple, what happen to the pride in the product you were producing?

Everyone does things a little differently. I love to "jam " along with iTunes ( or old Lp's) . Always have. That's where/how I've learned to play .
I'm sure leonieDF is giving a proper way to jam along on a keyboard with an iTune. He blows my mind all the time with what he knows. Nuff respects to him !
What I do is make a GB project I call "Jam With". I'll make several new tracks that are blank. Just has a few instruments named in the blank tracks. You can change those per song ...
Because I'm not concerned about changing the pitch / key.... of the iTune or the tempo ... I can simply play along with it.
Peace,
