Gotchas• 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 recording or in post production
• Mac OS X Intel-based native Audacity is still a challenge (some developers have created builds, others haven’t)
• 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)
