Good recording but quirks

Have been using for several months. The single biggest flaw is that after recording you must immediatly save the file before playing it back to listen and edit. If you just play it back then it closes the app at the end and the recording is lost. This is a serious bug but once you realize it it is just a routine thing. I do forget and lose recordings. Save your recording!

Excellent Product

I am semi-competent with software & was lookimg for an audiio file mgt program. Boson was right on -- their excellent app. with manual led me through the required steps to create lengthy audio files. They have a nice step by step cookbook section on the most regularly used outcomes their app produces. Also a lot of help with other internet materials that will enhanc the performance of the app. A must buy, particularly if your dinner conversation does not include "bit rate subtleties."

Version 1.6

Like most say, it is quirky yet is so very versatile. I use it constantly and like not love. I want to love this app. I recently updated to monteray and now it will not record internet or anything. I'll check to see if there is a soundflower update needed. I hope that's all it needs. If anyone knows the answer I would be gratefull. Thanks! Boson Team.
