The app is simple and easy to use. Gets good quality recordings, but even though it will give you a large wav file as an output, it won’t actually capture those extra frequencies that are usually sought after in wav files (looking at a spectrogram in Audacity to do the testing). Also it looks like the software will store the audio files in its system folders, even after you export them. You can delete them in the app, but without deleting them manually, now I may have some potentially very large audio files hidden in my hard drive taking up space. Overall great app, but not quite perfect.
Thank you for your feedback. The delete function removes the file completely, and temporary export files are cleaned up automatically when the app closes, you do not need to delete them manually. Frequencies are captured at the maximum range the app can receive.
