Suggestions
•
•
Backup early & often, and do not re-arrange your file system.
•
Mac OS X Intel-based native Audacity is very stable (in the past
this was not true).
•
If you change your audio settings within your operating system
with Audacity running will have random effects. Close Audacity
before making major audio setting changes.
•
You might want to invest in third party Noise Removal and
Compression tools (like RMS).
Don’t try to do a bunch of other things with your system and run
Audacity either in recording or in post production modes.
