Editing and Audio dropouts

Post by krisjop » Mon Nov 09, 2009 3:56 am

This is a new problem I'm having. I've always used Version 1.2.6 and burned everything with Winamp. When I edit (cut) the end of a track (let's say to cut off an announcer's voice), I save it as a .wav file. When I go to burn the CD, any song that I've worked on with Audacity has a fraction of a second of silence at the end. My other files don't. It's shorter than the buffer on a mp3 file but still annoying, especially when it's a concert. Any ideas? Thanks.

<<<I save it as a .wav file.>>>

Since Audacity doesn't save WAV files, we should figure out what you really did. Did you Export As WAV, or did you Save something you thought was a WAV file?

You're right. I clicked on export as WAV, I typed .wav to the end of file name. Bottom says Save as type: WAV (Microsoft) files (*.wav)

This only happens after you burn the CD?

Music CDs have Frames and if you miss a frame boundary, you can get odd results. Audacity used to have a preference where you could only edit on the frame boundaries, but I can't find it now that I'm looking for it.

That would give you a warning of impending doom.

That may be a mistake. Audacity automatically puts .wav at the end of WAV exports. If you force Windows to show you file extensions (a requirement in my book) you may find you've been saving MyMusic.wav.wav, and PianoSolo.wav.wav

I'm not sure I understand but I'll try. I want to burn a cd with 11 songs on it. If there's talking at the end of the last song, I just use the scissors in the toolbar to cut it off. Then I export it as a .wav file. Now let's say that the only song I worked on with Audacity was the last track. So the first 10 songs are flac files, the last one is a .wav file. I burn the cd. When I listen to it, everything is fine (no pauses between songs, seamless transition) until I get to last track. Now there's a very very brief moment of silence in between the end of the 2nd to last track and the beginning of the last track. This never happened before but now every cd i burn (where i've used audacity on some of the tracks) is doing it. I went to the wiki page and did everything it said to do. Still no luck.

As Doctor Laura would say, "You changed your story."

What happens if they're all WAV files?

If I start out with 10 flac files, put them in audacity, export them all as .wav files from audacity, then I get a drop out between every track. I was trying to explain that I don't think it's winamp causing the problem.
If I burn a cd of just flac files, there's no problem. If I rip a cd to my hard drive as .wav files, then burn it as .wav files, there's no problem.
It's only tracks that I export from audacity.
By the way, thanks for trying to help me out.

Even though I've been singularly unhelpful so far.

The files all sound perfect while they're in Audacity, right?

What is the WAV format you're using? Audacity 1.2 defaults to Mono, 32-floating, 44100 and not everybody directly supports that. It's possible to make MP3 music files with that which will not play on some computers.

Missed a step. Music CD sound format is 44100, 16-bit, Stereo. Hard to beat that.
