QT Pro 7.03 - audio recording - I just get white noise!

Just recorded an audio clip (off the radio) and what do i get??
Just plain white noise - completely useless!!!
I could monitor what I was recording as I was recording it and it sounded fine!
What's going on!???
(connection: Output of DAB into small mixer, into Audiophile 2496 soundcard - QT set to record quality "better" - hah! )

Use the Audio MIDI Setup application (Utilities folder).
If your recording setup is correct it should be identified with the app. Adjust the settings and test.
If you can hear it through your headphones or speakers you can also use WireTap Pro (free version) to record in .aiff format.

I have some dts cd's that I want to import into itunes on a windows pc and then play back on my apple tv 3 (i think its 3, about 9 months old) to listen to through my onkyo amp via hdmi as dts, when I play back I just get white noise.

I have some dts cd's that I want to import into itunes on a windows pc and then play back on my apple tv 3 (i think its 3, about 9 months old) to listen to through my onkyo amp via hdmi as dts, when I play back I just get white noise. I have seen lots of old posts which go on about converting files but am wondering wherher at the current time with the latest versions of itunes and apple tv whether this should by now be a virtual play out of the box solution.
I have tried connecting my atv to the amp by optical cable but that didnt produce anything better and am assuming that a hdmi cable should be able to reproduce everything an optical cable does.
Is this something I should be able to achieve without having to recode the files?
Tracks are imported to itunes as apple lossless, have tried setting the atv audio settings to auto and 16 bit, neither works yet I was told some time ago by an apple rep that the atv shoud be able to handle any type of audio as it just passes it to the amp to decode. I am not stupid but not that technical when it comes to audio and bitrates etc so any explaination would be appreciated.
Thanks in advance for any help

Willy, the procdedure you describe works perfectly for AppleTV G1. In fact, I frequently play DTS music discs ripped to my iTunes library as Apple Lossless (ALAC) and synched to the ATV. What happens is that, as far as iTunes and the ATV are concerned, a conventional stereo 16/44 audio file is being played; however my reciever detects the DTS data stream, and instead of outputting static, it decodes the 5.1 channels correctly. This process parallels the way DTS discs were designed to be played back: a conventional CD player is connceted, via digital out, to a DTS-aware reciever/pre-amp and the two channels of static are recognized as 6 channels of DTS-encoded audio.
However this process will only work if the player (CD, ATV, PC, etc.) sends a "bit-perfect" 16 bit/44.1 khz data stream to the decoding device. In the case of ATV G2 and G3, as has been discussed elsewhere, the unit resmaples all audio - including 16/44 PCM (Redbook CD) - to 16/48. While this is not a big deal for conventional audio CDs, MP3s, and AAC files, it mangles the fragile DTS datastream and renders it undecodable. The resulting static that you hear is just like the static you would hear if you played a DTS CD on a non-DTS capable system.
Sadly, I'm not aware of any easy way around this. You could use a program like Foobar (and the DTS plugin) to convert your DTS CDs to 6-ch .wav or .flac file. From there you could transcode the file to AC-3 and then mux it into a video container that ATV supports. You may need add a dummy video track, for iTunes/AppleTV to be ok with the file, though I'm not sure. This may be a lot of work.
Sorry for the bad news. I wish that the iTunes/ATV ecosystem had better multi-channel audio support.

Imovie11 audio on video clips does not convert when sharing, just get white noise

Imovoie 11 audio on video clips works in project mode, upon sharing to theater or file it generates whitenoise. Project mode has original video sound and added song paired correctly. Comes out as white noise in theater or new file.

Hi,
I did some more testing this time a shorter 2 minute video. Again trying to mute sections of the audio. I used garageband again to edit. Then convert the MOV with both FFmpegX and Flash 8. FFmepgX converted the file in about 1 minute, but still did not render the muted sections as mute.
I converted then with flash 8 it took about 30 minutes, god that is slow, but it did retain the muted sections. So I'm thinking maybe the FFmepgX converted has an issue with audio tracks that come from garage band.
Thanks,
Mike

Extracted audio from video file is white noise

Hi, I'm working on an animated series as a sound designer (my first gig as such). I'm getting .mov files from the director with some audio already added. In some cases, he just wants me to add tracks to what's already there and export it containing my audio and his.
The video looks OK (though the playback is pretty choppy, but that might be system limitations) but the extracted audio that shows up on the separate audio track is very loud white noise. There appears to be breaks where there's silence on the track but the audio is completely fuzzed-out and unintelligible.
The only thing I can think of is I'm using XP, he's on OS X. However, we both have current versions of QuickTime so why would it matter.
Any advice or insight would be appreciated. Thanks!

Hi grilch,
I'd definitely need to know the format of the audio stream. If you play the MOV file directly in Quicktime, does the audio play properly?
Thanks,
Durin

Is Logic Pro the Best Audio Recording Software for Mac?

Couple questions. I do a lot of audio production and work currently. I use a gateway with Cubase, and its not bad, but I feel like I need something mroe high end.
I'm looking at the 17 inch Imac. Does anyone record using this computer? How's it sound? Is there any way to put in a new soundcard or something if i don't like the current one?
Secondly, is logic pro the most advanced and best audio recording software for the mac? Are there others as well?
I know about Pro Tools, but it seems like there isn't anything high end enough that is TOO high end.
Does the Pro version have superior mixing capabilties. I am primarily going to be micing a guitar amp and having a mixer run into a firewire port, and also using a preamp for my guitar direct into the computers USB.
Lastly, how are the mixing features on Logic Pro vs. Logic Express? I do a lot of post production mixing as well, and use VST plugins. Speaking of that, will it accomodate using a drum program like BFD through VST or Midi like Cubase will?
Thanks for your time guys.

Yes, you do indeed need sth more high end.

It's not an iMac, but a faithful PowerBook G4 that I am using. Apples Core Audio is awesome. Your sound, however, will depend on your interface.

That's why we are here, and that's why you ended up in this forum as well
To me personally, Logic sounds warmer and bigger than any ProTools system I've ever heard. From what yopu described as the work you need to do, there is no comparable application. Logic also offers you many more features above and beyond what you currently need to do.
I know about Pro Tools, but it seems like there isn't

Everybody is using PT, and you should maybe get a Light Edition version of it. However, as stated above, Logic offers by far more possibilities.

For your purpose, Logic does have superior mixing capabilities. In my humble opinion, only the popularity of PT made it become the choice of studios and engineers, but things are turning...
Lastly, how are the mixing features on Logic Pro vs.
Logic Express? I do a lot of post production mixing
as well, and use VST plugins. Speaking of that, will
it accomodate using a drum program like BFD through
VST or Midi like Cubase will?
If you do post production mixing, forget about Logic Express altogether and go for Logic Pro. LP will accomodate tons of plug-ins, and it comes with a bunch of great one's as well!
The format for the plug-ins is called A(udio) U(nit) and works flawlessly. Many VST plug-ins are also available in AU format and the development of those is moving fast forward.
In other words, yes, you will be able to use BFD in Logic by means of the AU format.
Thanks for your time guys.
You're welcome.

I am running a website called mediahawk, I cannot play audio files I just get a black box where the media player controls are

I log onto the site when I try to play an audio file I see a black rectangel where the media played controls should be and the file will not play.
I have tried updating the plugin.
It works fine in IE.
Anyone have any ideas

Recording Cap 5 get white slides

No matter what I attempt to record, web sites, PowerPoint ppt file, etc, all I get are white slides. I do have mouse movement showing, and some captions, but nothing else appears. I've recorded in the past, from Captivate 3, 4, and 5, and have never had this problem.
Using Captivate 5
Windows 7
Dell laptop
Any ideas?
Thanks,
Barb

Hello,
Welcome to Adobe Forums.
Which version of Adobe Captivate are you using ? (CP5.0.1 or CP5.0.2 or CP5.0.3)
Did you try recording with a different user account on your computer ? (Built in Administrator)
Thanks,
Vikram

Something to worry about or is it just router 'white noise'?

I don't think this is Arch specific, but felt the Newbie Corner would be an appropriate place to make this thread. I apologize in advance if this is a stupid question, but I seem to get a lot of blocked UDP packets from various IP's directed at port 55881 in particular. Occasionally, I'll also get attempted TCP connection requests to port 23, 445, and some ports in the 8000's. If this is something to worry about, what can I do to configure my system so that I can be at ease (or close enough)?

illusory wrote:My logs on my system check out well. The connection attempts I mentioned are all from my router's log. How can I check to make sure there isn't anything running listening in on those ports? What can I do to disable these services if necessary?
As a device, which faces internet, I guess it's normal for the router to detect some connection attempts either by mistake, or from port scanners, kids, etc...
The services run on your machines, not on the router. The only one on the router should be either telnet or httpd for configuration. In order to protect your internal network, you only need to disable remote adminitstration on the router (or whatever it is called in your case, that is the router should be accessible for administration only from the LAN) and port forwarding (also on the router, so that requests are not forwarded to the LAN). Enjoy

I turned off my iPod touch and later tried to turn it on again and got a blank screen. Now I just get white or a blank screen. Screenshot and voice control work and it responds to charging. I already tried resetting it.

It was fine a few hours ago and isn't working now.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Does the MacBook Pro have an audio input?

Looking to take output from external source (cable box) and run into my MacBook Pro. Can I do this? What application would I run on the computer to listen to the input?

Hi starbux48,
Yes, on the 17" MBP you have a dedicated line and line out. Take a look at the sides of your MBP, and you should see two 1/8" jacks, one has a headphone picture and the other something else. This "something else" is your audio input. Just get a cable that has an 1/8" jack on one side, and stereo RCA (assumed for a cable box) on the other. I am not very familiar with Macs and audio recording, but I would imagine that whatever you intend to use to record will have a setting to select your MBP's audio input as the source. Good luck!

Big problem with an audio recorder iTunes

I bought Ondesoft's Audio Recorder specifically to get music from other apps into iTunes. I successfully recorded something (as AAC 192) and it appeared in the Music/Ondesoft Audio Recorder folder.
I tried to drag it to iTunes but it didn't appear, though it would play in QuickTime. Then I noticed that the filename ended .aac and not .m4a so I changed it and immediately the icon changed too, to the "musical note". I dragged it to iTunes and STILL it did not appear!
So I changed it back to .aac and now not even QT will play it.
These are the output format specs in the Ondesoft app :
output format aac
MPEG4-AAC - Normal Quality( 44100 Hz, stereo , 192 kbps )
In the profile information it says:
[Audio]codec=aac sample_rate=44100 hz channel=2 bitrate=192 kbps
So what's wrong? Why doesn't changing the filetype to .m4a cause iTunes to load it into its Library? And why has changing the filetype back to .aac caused QT to stop 'seeing' it? It still plays ok in the Audio Recorder app.

Oh, I know what has happened. I went back to the Audio Recorder, and saw in the 'Output Format' list that while aac was top of the list, there was also m4a lower down. So I re-recorded the music as m4a and this time it loaded into iTunes ok.
But here is a mystery - the profile information for both formats was the same, i.e. aac 41000 Hz 2 channel. If both are exactly the same format - and I'd always believed that iTunes's default format was AAC - then why does iTunes recognise one but not the other??

Using Pro Logic X to record. I have several tracks and I'm trying to record an audio track. I have the mic connect to Avalon 737 then into apollo interface. When I record all track are being recorded into that track. I can't just get the audio to record.

Thanks for responding. Everything seems to work right except for the when I plug into the 737. Ok let me see if I can be more clear. I had this set up done with two representatives of Neumann, and DBox. Here it is I hope this helps. 32 Channel snake (24 Inputs 8 outputs) Channels 1-8 from snake to my Octopre for Drums. From Octropre output quarter inch lines into the Apollo 2, quarter inch input. This is so that the Apollo 2 is taking the drum tracks. Snake Channel 9-12 into Apollo 1 channels 1-4 xlr. Snake Channel 13-16 into Apollo 2 Channels 1-4 xlr. Snake Channel 17 into the 737, output of 737 into Channel 5 of the Apollo 1 quarter inch.
Ok The Dbox. Sum output L&R into channel input 7&8 of Apollo 1. Apollo 1 output channels 1-8 into summing input channel 1-8 of Dbox. Apollo 1 main L&R going to main analog input L&R of Dbox. Spid out to DAW input of Dbox. I have both ADAT of both Apollos connected by optical wire. Also have port 2 of Apollo 1 into port 1 of Apollo 2 connected by Firewire. Let me know. Hope I got it right. Thanks for responding.

Audio Recording Software. Quicktime Pro?

Good day to you. I'm just curious about something.
I've been looking for an cost-effective way to record audio on my PC.
Does QuickTime Pro allow you to record audio using a microphone that's plugged into your computer?
Oh, I should also mention I do not have an Apple computer. I run a custom built Win7 PC.
Thank you very much for your time and reponse!

Very cool. Thank you very much.
While I'm at it, I'm not planning on like a podcast or anything but, is there a good mic you would reccomend? If any? Or would any run of the mill Logitech headset w/ mic would be sufficient?

Wich one best for Audio Recording using cubase and pro tools? MBP md102 or MBP md103? i often using a lot of VST

wich one the best for Audio Recording using cubase and pro tools? MBP md102 or MBP md103? i often using a lot of VST too

Well, I've been trying this for a while. By my calculations, at this rate, installing all the applications one by one and trying to restore all the data manually will take me about six years. I would finished just in time for the Tokyo 2020 Olympics.
The main problem is, I don't know where all the bodies are buried. Just one example, I'm using Cornerstone for an svn client. I have working copies of multiple repositories on my computer. I really don't want to set them all up again, and I can't figure out where the Cornerstone preferences and all settings are stored. I couldn't find them in the Library anywhere.
And that's just one case.
I haven't done much with my MacBook Pro yet, I think in retrospect the easiest course of action is to reinstall OS X as though it were new MacBook Pro, start from scratch, and use my Time Machine backup with the migration assistant and go from there.
And that's what I'm doing right now. I'm in the middle of reinstalling OS X.
Afterwords I'll use a clean app uninstaller application to get rid of all the applications that I'm not using. And I'll just hack away at directories that I know I haven't looked at for years, with the confidence that I have a backup both in Time Machine and in CCC and also on my iMac. That's three backups.
I would rather start out "light", but I can see it's just going to take forever and a day to get it done. Anyway, fortunately nothing is carved in stone, and I can always try again if I want to. But dealing with all the documents and all the applications one by one separately was just obviously going to take too much time.
I'll report back on my results. And I appreciate your suggestion.
Doug
