I'm in the process of trying out Audiomulch to see if it is something that would fit my workflow. First, a HUGE thank you for making the trial 60 days - you don't know how nice that is. You simply can learn a new application in 10 or 15 days.
Both formats listed in the subject (flac and ogg) are open, and I would love to see support for loading them. I was a bit sad to see that most of my samples (gleaned from sites supporting open formats) cannot be used. They can be converted, yes, but that's a bit of a pain.
Thank you for your hard work!
