I find that Peak is the application which is most suited to the kind of work I do to post-process recordings from my FR-2. It seems designed with an understanding of the process of converting a big file from a live show into a set of tracks. Editing, converting to regions, exporting to files, are all intuitive and straight-forward, with a gentle learning curve.
Some here have a deep hatred for Peak, probably because of nasty experiences with the company, BIAS. BIAS, and especially Steve Berkely its principal, are incredibly arrogant. Also, Peak is a cpu hog. Not much of a problem with a machine which runs faster than 700MHtz.
My only issue with Peak is that it won't work with files >2GB, so I have to chop up my files in Spark first. I've heard that the new version of Peak (5.0), can handle the big files. Spark is fine with >2GB, but I cannot handle it's ui. Workflow in Spark is totally non-Apple hig, bugs me muchly.
There is a new option out there, Wave Editor, which looks interesting. It requires 10.4, so I'll check it on my desktop machine next week. If anyone cares, I'll report back.
there are also lots of free option, Audacity being one of the best.
Cheers, Chris
Update: Peak 5 won't handle >2GB, neither will Wave Editor. Looks like Spark is the only one to handle large files.
