Suggestions • Backup early & often, and do not re-arrange your file system. • Don’t try to do a bunch of other things with your system and run Audacity either in recording or in post production modes. • 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). Saturday, June 7, 2008 49
