Audacity Forum

Please see my above comment about 435 semitones/440 semitone tuning. If you are concerned about 0.001% accuracy, that is irrelevant. The design tolerance on most tape/cassette machines is around 2%, and even professional Revox machines were only designed to +/- 0.2% You can't do this sort of job if...

How far out is it to the nearest 1 % ?

For recording in a high quality format, the SD card needs to work fast to keep up with the data, otherwise bits of data will be dropped and it will sound like distortion (push it further and the "gaps" become obvious. I had this problem with my Zoom H2 - the sound quality when recording in...

Are you sure that you are using % and not "semitones"?
1% pitch difference is very small - few musicians play closer than a couple of % to "in tune"

Once you have it within 1%, use the same procedure but go up or down in 0.1% steps to get it bang on.

Edit menu > Remove Audio > Trim
(keyboard shortcut Ctrl+T)
Ensure that playback is "stopped" when you need to edit (not play, pause or record).

There is no "automatic pitch matching", but this simple procedure will probably help: (tip: spacebar to Play/Stop. Shift+spacebar to "Loop Play"/Stop) Import both versions into Audacity (one above the other). "Edit menu > Preferences > Tracks" - set the "Solo Butto...

Considering that Nyquist plug-ins are simply written as plain text files, it is amazingly versatile. Keep in mind that Audacity does not do anything in real time other than record and playback, so there's no "real time reverb" or "real time anything else", but you can perform vir...

Your set-up looks to be correct, but I've just tried running Debian Squeeze in Virtualbox and got exactly the same problem. (I run Debian Squeeze as my main machine on real hardware and this problem does not occur - If I find a solution I'll post, but as a workaround, just use ASLA or Jack (these bo...

It sounds like your computer may be a bit short of RAM, so you will need to manage that carefully. Before starting any major recording sessions it would probably be best to reboot so as to maximise the amount of RAM available. You can check how much RAM the computer has by right clicking on "My...

The issue here is made a lot more complicated by the fact that you are running Debian in a virtual machine. The way that the "virtual sound system" communicates with the "real (host) sound system" can be very confusing. If playback is at a consistent (but wrong) speed, then the p...
