"Pops" During Playback
I recently used Audacity to get a concert I had recorded with my jazz band at Miami (OH) onto a CD but found that no matter how slowly I burned the CD, there were loud "pops" in spots. I did not crop it into individual song tracks and wonder if this makes a difference (i.e., I was given a CD with the whole thing in one WAV file with no stops). Thanks.
Re: "Pops" During Playback
Does the recording play in Audacity without pops?
Does the Exported wav/Aiff file play without pops?

Re: "Pops" During Playback
Audacity defaults to 32-bit floating for one of its sound file specifications. That makes a dandy editing quality, but many music CD authoring programs have no idea what that is.
Open up the show in QuickTime Player and press Apple-I to get the INFO panel. A good pre-burn panel will say 44100, 16-bit AIFF or WAV. You can even have an MP3 file and have it work OK, but 32-bit floating may not work so well.
If you have QuickTime Pro ($30-US), you may be able to just export the show to AIFF 44100 16 bit right there and I bet the pops go away. I'm not sure you can do that directly in Audacity, but that maybe possible, too.
You do know you need a CD Authoring Program, right? You can't just drag the sound file over to a blank CD on the desktop. Open the show in iTunes, make a playlist with the show in it and burn by following the instructions.
I personally would break the show up into songs with Audacity, but I may be getting ahead of the game.

Re: "Pops" During Playback
Sure you can - I have Audacity set at 32-bit floating 44.1kHz for capture and editing - and then when I export I use Audacity to downsample to 16-bit 44.1kHz (just select the right export option). Audacity downsamples to 16-bit - you can even specift which type of dithering you want applied in the downsampling process (accesed via Edit>Preferences>Quality).kozikowski wrote:Audacity defaults to 32-bit floating for one of its sound file specifications. ....

These settings produce very good quality CDs for me.
