I am having this same problem now, with Audacity 1.3.9 (Unicode) on Ubuntu 9.10. Currently attempting to save a project containing one stereo track and one label track. I'm not using any strange filesystems, I've verified that permissions are good and plenty of free space is available...... I'm won...

The USB port hasn't changed.. The drivers have changed and your default Audacity settings may have changed. Do you have "PulseAudio Mixer" ? It is necessary for setting up recording on a default Ubuntu system, but for some reason was not installed by default on Ubuntu 9.04 (I don't know i...

Download the ZIP version (for Windows) from this page: http://lame.buanzo.com.ar Extract the contents of the zip file into your Audacity folder (which is in "Program Files"). Open up Preferences (from the Edit menu) and on the "File Formats" page, click on the "Find Library&...

Or in the case of a mono show, make a stereo show with the "backup" on the right channel. ... Split them, apply the effect, and then rejoin. That's almost simulating "group tracks". There is some discussion of how track grouping might be implemented here: http://wiki.audacitytea...

To confuse it even more you can get lossless AAC files also, but they're not really AAC (sometimes "MPEG4 audio lossless" with an incorrect file extension). To try and keep it reasonably simple, most AAC files and most WMA files are "lossy" and it is very unsafe to assume that th...

Unfortunately both AAC and WMA formats are also "lossy" compressed formats and will also degrade sound quality. The safe "lossless" formats to use are either: WAV, AIFF, or FLAC. "FLAC" uses compression, whereas AIFF and WAV are uncompressed so FLAC files are typically ...

Audacity does not have "per track" undo (and I don't know of any multi-track audio editor that does. You could perhaps suggest it as a feature request, but I can see some fairly major difficulties with implementing it. For example, what happens to the Undo histories if you make two mono tr...

If you want the peak amplitude to be 80%, first use "Amplify" with the default settings (that will bring the peak level up to 100%) Then, select the track and from the Effects menu click on "Nyquist prompt". In the Nyquist prompt text box, enter this code: (scale 0.8 s) and press...

It sounds like your USB port cannot handle the amount of data. If you are recoding and playing back simultaneously over USB, the amount of data that the USB port has to handle is double. Try running it at 44100/16 bit (CD quality) and see if that works.

What's wrong with leaving it in mono? If you are distributing it on the internet as an MP3 you will be able to use a lower bit-rate for the same sound quality compared to a stereo track. That means faster downloads / smoother streaming for your audience.
