HTML5 Canvas mode audio quality issues

Trying out the HTML5 Canvas mode of Flash CC 2014, and have banged right into a couple of show-stopping problems with exporting audio--
Every audio file I've given it, Flash has converted it to MP3 with a loud click at the end that is not present in the original.
In HTML Canvas mode, it seems there is no option to modify the Default compression setting for audio. So the only way to export MP3s as anything other than 16 kbps mono is to manually change the compression on every single file. Am I overlooking something?

Yes, I already pointed out in the first post that you can change the compression at the individual asset level and that there doesn't seem to be any way to change it in the publish dialog.
Seems a bit absurd that the ability to change the default compression got left out of HTML5 mode. This has been core Flash functionality since pretty much forever.

Poor On Call Audio Quality issue

Hi guys,
Im aware everyone has issues while listening to music via the headphones as i have that too. Thats something i can live with.
However, what i cant live it is poor on call quality issues without the headphones. The other person on the call doesnt sound all that loud, clear n crisp to me. I keep having to press the phone more towards my ear to hear them louder and better. Its sub par. Its worse than any phone ive used.
I just switched from an iPhone to this and im very dissappointed.
NOKIA PLEASE FIX THESE AUDIO QUALITY ISSUES!!! This needs more addressing than the battery issues..

Happens to me on Lumia 800 (12070). Usually at the beginning of the call I can hear the other party well but the call quality seems to degrade slowly over the course of the call. I've tried pressing the phone closer to ear and going volume up or down but in some points of the call I have really hard time hearing what they're saying. Then it goes away and I can hear well again. It's not so much volume issue rather than the call getting really unclear.

Flash PLayer Audio Quality Issue

Howdy,
I am having a strange issue where I am hearing quality issues in the playback of sound on any flash content (youtube etc ..). The background music or backing tracks all play fine, but the Vocals / Voices in the video are quiet and distorted. The best way to explain it is, that I can hear the music on a music video ... but the words that the artist is singing aren't there.
Strange ....
I am running Windows 7 64-bit prof. on a brand new machine.
i7 X980X
12 gig memory
Realtex onboard sound from an EVGA X58 motherboard.
I have tried clearing and re-installing the installs, codec packs ... etc ... additionally this problem is present any time I play flash content in any browser or with a stand alone flash player.
Also, my sound works fine in games and local audio. And it passes all the surround sound tests, so I am sure the cables are hooked up appropriately.
Any thoughts ?
Thx !

Sadly, none of those seemed to help.
I was able to track down the issue. I have a new graphics card, and GTX 580
with HDMI support. It also installs an audio driver so it can pull out the
audio and send it out the HDMI port to a monitor with speakers / TV .. etc.
Once I disabled those drivers, everything started working normally. It was
some very strange symptoms.
Thanks,
C

Audio Quality issues in You Tube

Hi Guys
I am really struggling to work out how to submit my music video to 'You Tube' without severe degradation of audio quality.
V. Happy with the vid. side - H.264 output with optimised parameters on all fronts (debatable I know - but I guess I'm aware of those parameters)
Trouble is the whole point is the music - which just loses it.
The export from origin added to project in Premiere is 24bit, 96khz sample rate - mastered to optimised preference and sounds pretty cool in direct
comparison to random productions from other sources.
(ie: your favourite band music through stereo system (decent speaker output) via CD Rom)
Have attempted all available audio parameters within CS6 to no avail.
Whatever I do - the audio sounds the same ie: diminished
I know 'You Tube' compresses again but how can I avoid this? - Would love to hear from anyone who has had, is having the same issues!!
Suspect that this requires some kind of server side 'pay for' service, I just can't identify where.(or that my master is crap)
Kind Regards

You won't even get CD quality sound out of YouTube, let alone anything approaching 24/96 quality. I think you're only avenue for delivering that is DVD-Audio, which never really took off.

CD/MP3 Audio Quality Issues FCP 5

Hi all;
I'm running FCP 5.3 on Tig 10.4.3
the video in my HD PAL project behaves fine.
the audio is taken from an mp3 file that came from a CD. it has been converted to 48.000 and 16 bit stereo, which matches my sequence settings, which were those in the HD Preset.
I know these are common compression issues, but this is different. The audio plays fine in the viewer, and it also LOOKs good when I double click on it (from within the sequence) to see the waveform in the viewer.
But it all goes wrong when I actually play it from the timeline: it goes all crackly and fuzzy and slightly slowed.
This only does not happen if in my sequence settings I choose "uncompressed" from the compression settings, but I obviously want to remain in HDV compression as far as the video goes, so I am not willing to make the whole project uncompressed.
I tried lots of different settings and ways of exporting and recompressing the audio file, but nothing seems to work. Also, this same file used to play just fine from the timeline in FCP 4.5... but I had to upgrade to FCP 5 because it supports HDV, which is what I shot.
Muchas gracias for any help.
M

Poor Audio Quality From Exchange 2010 UM

Hi,
I'm experiencing an issue with our Exchange 2010 Unified Messaging system in that the audio quality is suddenly rather poor. We are using Cisco Callmanager 7 for our phone system. When you call an automated attendant, hit the "messages"
button or call the extension to go to voicemail, the audio you hear "crackles," or sounds like it is skipping slightly in that there are brief but noticable interruptions in the audio.
The audio quality issue only occurs when you are connected to voicemail or automated attendants, but not when conversing to other people on phone calls, so that leads me to believe either some interoperability between CM and Exchange UM is malfunctioning, or
just something in UM is a problem. Also, if you listen to voice messages through the computer instead of over the phone, the quality is fine. The problem seems to be mainly with calling in to the UM system.
What can I do to properly troubleshoot this? I have found the Exchange 2010 UM Troubleshooting Assistant, but I have to wait another 2 weeks before I can install Service Pack 1 due to downtime window restrictions. I'm not coming up with a lot of
documentation involving this, so if anyone has any information they think might help me get to the bottom of this I would apprecaite it.
Thank you.

Cisco Callmanger and UM are on the same LAN.
I highly doubt that QoS is the culprit here, simply because there aren't any issues with phone calls. If QoS was dropping VOIP packets, then IP phone to IP phone calls would also have poor audio quality. If I call somebody on another IP
phone on the LAN, the audio quality is perfect. It is only when you are connected to the UM system that you hear the poor audio quality -- either listening to voicemail prompts, listening to actual voicemails, listening to the automated attendant --
anything in which UM is on one end of the phone call.
It also seems strange that this is somewhat intermittent. When the issue first occurred, it was definitely happening every time you called in to the UM system and I could repeat the issue by simply pushing my messages button and listening to the welcome
and prompt for a PIN. I restarted the Exchange server at night, and the next day it was intermittent with people calling the help desk to say they were getting poor audio quality from UM but when I tried to repeat the issue I could not.
I also have users complaining of intermittent slowness when using Outlook, which may be totally unrelated. I have been running Perf logs on the Exchange server for the last couple of weeks othe CPU, Network Connections, Exchange RPC totals, etc.
and can't find anything that is using too many resources.

Poor imported audio quality in Captivate 4

Hi Everyone,
I'm having some serious audio quality issues with Captivate 4. I'm recording my audio in Audacity and importing it into Captivate. The audio sounds great in Audacity, Windows Media Player, iTunes, and everything else I've tested it in. However, once I import it into Captivate and press play, it sounds horrible. It's thin, tinny, and robotic. The degradation in quality is considerable. I've tried recording my audio as both .mp3s and .wavs, but they both sound bad once imported. I've also downloaded all of the available patches, including the patch specifically designed to address poor audio quality in Captivate 4. I've tinkered with every audio setting I can find. No luck. I have noticed that the shorter/smaller audio files are less garbled, and really short files are sometimes not garbled at all. I would record directly into Captivate, but the audio sounds even worse when I do that. Anyone have any idea how I can remedy this situation? Just for background info, I'm running Captivate 4 on a macbook running XP via parallels.
Thanks

Hi,
I responded here in the forums because I figure other people might need this info as well.
In Audacity, I go to:
Preferences -> Quality -> Default Sample Format and set it to 16 bit.
Then click OK.
When you record new audio tracks, they should automatically be set to 16 bit.
Does that help?

HTML5 Canvas issue with iOS Safari

I am trying to build a painting application in HTML5.
I have an HTML5 Canvas in a div. This div is masked with an SVG file using -webkit-mask.
On iOS Safari and in iBooks Fixed Layout: When you zoom the page by gesture, the mask suddenly stops working revealing the entire canvas and the contents of the div.
1. There is no problem if the contents of the div is an image. Problem is only with Canvas inside.
2. The problem seemed to happen when the zoom crosses a mark - possibly 50%. I.e, if you have already zoomed over 50% and refresh the page, there is no problem until you zoom out below 50% and vice-versa.
Any help would be greatly appreciated.

Hello Corey,
I have been trying to work on this issue, but I haven't made much progress
Breaking up the project into several small chunks seemed to help for the iPad, but it's not ideal.
I'm seriously struggling with Android tablets though. Android doesn't support flash anymore, as HTML5 is the "future". Google Chrome on Android tablets has problems with synchronizing animations and sounds cutting out (works fine on a desktop or notebook). FireFox on Android didn't have the sync or sound issues, but it crashes at random times. I think the root cause behind all this is HTML5 and the browser. I couldn't figure out the difference between chrome on desktops and notebooks -vs- tablets. I went to html5test.com and compared the two browsers, and there is definitely a difference between the two browsers.
When you look at authoring alternatives to Captivate, it seems like their customers are having similar issues.
I'm still looking for a workaround. I'll let you know if I find anything

Terrible audio quality in 5.1 mode

Hi !
This issue has been here for a while, but it's only now that I come to try to get a fix for it ...
So, it's been a few version that I've noted that the sound was really bad when playing videos on youtube and came to realize that this was fixed when I switched my audio configuration from 5.1 to just stereo in the windows configuration.
I've searched a bit and it seems that flash proudly converts stereo audio sources into 6 channels using the Dolby ProLogic II algorithm. This would probably be fine if it was customizable and de-activable, which it is not right now.
From what I hear, my subwoofer is overloaded with sounds and seems to be used to play low-medium sounds rather than just the deep basses it's meant to.
I have also noticed that, in the sound configuration of windows, I can specify whether my satellites have a broad spectrum or not, but this doesn't seem to change the issue.
Sure, I can get my audio quality back by going to the windows sound configuration and switch to stereo, but I don't want to do that everytime I use flash and then change it again everytime I play a movie or a video game.
The simplest way in my opinion would be to have an option to disable that audio conversion in the flash client.
In case the algorithm for upgrading stereo to 5.1 is customizable, could we perhaps also get access to these parameters (for this kind of algorithm, I would really expect a way to specify the ranges for the individual speakers)
Thanks,
WishGate.

Standard track height:
and no waveform. Now extend it vertically,
and voila, the whole waveform. Just drag down the bottom of the audio track to make it wider (vertically) and there you are.

Depeche Mode's new album Audio Quality

I purchased and downloaded the new CD (playing the Angel) thru iTunes, etc etc,
but I don't like at all the file's audio quality, I can hear a sort of digital distortion, specially on the hi frequencies, like a bad rip thing, it's very subtle, but I can hear it and really bothers me.
I guess the next logical step is to listen the original CD and compare.
so
does anybody hear the same thing?
also I would like to know what to do... (for example can I have my money back, can I re-Download the album, etc)
thanks in advance

well, their first response was to "encourage" me to check an article about how EQs work and how to use it... :s
I'm a big Apple fan and defender, and I know this is part of a long systematic procedure, but this response really ssuuxx
Or maybe I forgot to tell them that I'm a Sound Engineer.
Oh well...

Captivate 4 - audio editing issue (distortion heard once published)

Hi -- I am working on a 17 minute movie with audio on each page (total project size about 60mb). I recorded the audio outside of Captivate and imported the .wav files (for some reason the .mp3s sounded too tinny). When I started the project in November I had no problem editing the files (removing sighs/pauses, inserting silences) and adding to the slides.
For some reason in December I started running into issues. I would go to edit a sound file on a slide, it sounded good when played back, but when I previewed or published the sound file I just edited it would have a layer of sound on top of it making it distorted. Also, I no longer have the ability to add silence at the beginning and end of the audio file (which I was able to do in November). I add it in edit mode, can see/hear the pause but when I save and close out those beginning and end silences disappear.
I just got final feedback and was making adjustments on two slides but the same thing happened. The audio files I edited would sound distorted when played back in swf form. The only way to save the project was for me to open an old archived version, export that audio, re-import to my production project and it worked fine. But I cannot edit it in Captivate. If I do, the distortion gets added.
I am publishing as audio quality: MP3, 96kpbs, 44.10 KHz.
Any thoughts? I like to edit directly in Captivate and don't want to have to do the extra step of editing the audio in another application.
Thanks!

Hi there
If you want to add silence at either end, your first step will need to be to position the playhead ever so slightly away from the true end or beginning. Otherwise, Captivate ever so helpfully discards the silence. So the silence needs to be inserted between the ambient noise.
Actually, this is a nice segue into a technique you may wish to use. Select a section of the ambient noise and paste it repeatedly. This will eliminate the "dead air" you hear with total silence. Sometimes inserting silence is one of those - "the cure is worse than the disease" sort of things.
Cheers... Rick

UC320 call forwarding, poor audio quality

On nights and weekends, I have the UC320 set up to ring the main hunt group of 3 office phones for 4 rings, if no one answers, it forwards out to another phone number. Now here is where my problem comes in, When the calls comes in from caller to the UC320, the caller hears the 4 rings loud and clear on their phone, then when the UC320 forwards the call to the outside phone number, the sound quality drops significantly and the rings are almost inaudible. When the forwarded call is answered, the voices are almost in audible and very distant and a bit staticy. This only happens in the forwarding mode, not on normal call throughtout the day when someone calls in.
What setting could be affecting this. The UC320 is on Time Warner Cable lines. And when those lines are called directly, call quality if perfect. As soon as the call is forwarded out whether that be to a Cloud based system like Phone.com or Vonage or even another land line, the call quality issue occurs.
Has anyone experienced this type of issue? What settings would have bearing on this?
Please Help!
Thank you.
Tony.

Hi Sleeze,
I do not have Skype so I can not judge. Most of the posts I have read seem to suggest iChat Audio is better.
However Skype could have updated their app.
As long as iChat Bandwidth and Quicktime streaming setting in System Preferences are not capping your connection I can not see any other changes you can make. (unless you are "too far" from the camera). If the last is the case it may pay to adjust the volume in System Preferences > Sound >Input tab as this is the master for iChat. I am not sure if it is the same for Skype.

Safari doesn't load pages containing html5 canvas on iMac

Suddenly Safari either is very slow to load or doesn't load some pages at all.
I have tracked it down to be pages containing html5 canvas element.
This happens only on iMac and Macbook Air. It doesn't happen on iPad nor on Safari on a Pc. It will happen on the Mac computer both when the pages are out on the internet and when the pages ar locally stored. It's driving me absolutely mad!
I've tried emptying cache both through Safari menu and by removing Safari's Cache.db, I've reset Safari preferences, restarted, and changed DNS to Open DNS (though it seems strange it should be an issue since the problem also occurs when I run the site on localhost).
If I open the page directly entering the url in the adressbar it works fine, it is when I try to access it from a link on another page on the site it doesn't load. If I press reload it will load fine. The link from other pages can be either an html <a href="url"> tag or javascript window.location or window.location.href neither works. The weird thing is it worked fine until just yesterday. And it works fine on every other machine except the Macintoshes. WHY

Hi Carolyn,
Thanks for the quick reply. I've tried everything you wrote now, however the problem remains.
One thing I've noted though is that the page actually loads but it takes very very long time, and sometimes when the pages have been loaded the images doesn't look quite right until I hit the reload button.
I've been thinking about another thing, there are a lot of effects like round corner, shape and text shadow, can it be these that cause the problem? I still think it is very strange though that it all of a sudden stopped working and that running it on PC or iPad everything is just fine.
Another thing to add is that the computer is very new just got it like 2-3 weeks ago, and haven't hardly added anything except got Xcode, macVim, firefox and Filezilla.
Also just before the problem appeared I ran a page with javascript that had me caught in an endless loop of alerts. Got that fixed, but ever since that some pages won't load correclty...
Is there possibly anything else I can do to fix this?
