I have recently begun using audacity for Mac OS X to record some
casettes and convert to mp3. The cassettes contain ~ 30-45 minutes of
speech that I do not want to break into smaller fragments. I typically
have 1.3 gigs free on my hard drive when beginning a recording. (more
approx 4 times my required length at CD quality audio). I record using
a Griffin iMic.
The recorded audio is recorded in stereo at 32 bit floating point,
regardless of how I set it in preferences or the project file (not sure
if this is an iMic thing or an audacity thing....) but that's ok
right? I have plenty of hard disk space and since I don't care about
stereo I can cut one of the tracks and cut the file size in half right
there. Then I can downgrade to 16 bit (or is 32 bit floating actually
smaller than a fixed 16 bit somehow?) That should cut my file size to
1/4 pretty easily without losing much (if any) quality - it's coming
from a cassette anyways...
The issue is this:
Regardless of whether I save first and then trim, or trim and then save
the disk fills up and I can't save the file. If I save first, I at
least have an unwieldy large version, but it's there. If I trim first,
I can't save anything. And if I save and then trim, and then try to
save a new copy - the new copy is larger than the original, even if I
try to remove everything from the undo history.
I have looked through the tutorials, and can't find any relevant
In short, is there any way to erase temporary files as a new file is
being saved in order to conserve disk space. I understand that if the
computer crashed in the middle of the save, that all would be
effectively lost, but come on - how often does that happen when running
*nix? When using large audio files, there should be a way to save
without effectively having to have 2 copies.
Additionally, exactly how do I remove all the extraneous information
from a project when I DONT want to be able to undo previous actions?
This is a great feature, but becomes too unwieldy with certain projects.
Hopefully this makes some form of sense!
PS> Other than this issue, I love Audacity!
PPS> If someone has any ideas about audacity and the imic and
recording in mono at 16 bit, I would love to hear them!!!
