Hi,Audacity's maximum recording time is calculated using the amount of free disk space.
a guy saturday tried to record the entire nights music onto his PC laptop, using Audacity. This is 8 to 9 hours total. The screen showed the appropriate stereo waves right up to the end I believe, I was keeping an eye on levels most of the night. Apparently when he first tried to save the single file, it showed a size of zero.
I got a text from him to say that he eventually managed to save the first hour and a half, and that he had to manually piece together 16000 temp files to get the total recorded up to 6 hours or so, losing the last hour and a half.
What is the maximum recording time, and/or is there a way to do a better job of recording in the first place? I don't know any details of his system at all, just wondered if I could help him out. He's somewhat embarrased and frustrated, as he tried to do the same last month but didn't realise that when he shut the laptop lid down, Audacity stopped recording, so only got the first hour and a half.
I've had lots of problems during long Audacity recordings - usually it just crashed leaving a temp directory full of fragments. This has been on PC, Mac and Linux. In the end, I gave up trying to use Audacity as a recorder (I use SoundStudio instead) because it would crash after a random period of time (usually around the 50 - 70 minute mark).
The temp files created by Audacity are .au format and are each 6 seconds long. If you are recording in stereo, then you get a pair of .au files for each 6 second block where (usually) the even numbered file corresponds to the left channel fragment, and the odd numbered file to the right channel.
Learn from my (bad) experience - don't use Audacity for recording anything that you consider "mission critical". Its fine for a bit of basic editing afterwards, but not for long recordings.
I have had great success using Audacity for roughly 1 hr recordings on a
regular basis. The only annoying feature was having to save to MP3 before
copying to audio CD.
Just choose "Export as WAV" from the File menu and you're good to go.
