When you select an audio file in the Mac Finder, Snapper immediately appears right beneath the current window, showing you the wave form. Hit the space bar or double click in the wave form to play. Or use auto-play to start playing the moment you select the file. Vari-speed is available too. In the Snapper wave form you can select a part of the sound file and drag it out to create a new file, drag it to any sequencer or audio editor, turn the selection into an MP3 file, split stereo files into separate left and right files or vice versa, convert to MP4 and attach it to an e-mail in one, and export to AIFF, WAV, BWF, MP3, or M4A. Snapper opens over 50 sound file formats. That includes compressed files, split stereo, 192kHz, 5.1 surround files, red book audio, CDs and movies containing audio. It shows loops, markers, timestamps, regions, BWF annotations, even album covers. You name it, Snapper can handle it. For some formats you need to install external components.
