jd.Edit is a waveform editor for iPhone, iPad and Mac — cut audio like on a desktop, one purchase for every device. On top of that, the app records through USB audio interfaces in true stereo and remembers your input choice. And it writes MP3 with its own encoder, calibrated against the reference encoder LAME.
