When you select an audio file in the Mac Finder, Snapper immediately appears right beneath the current window, showing you the wave form. 

Play
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.

Drag, Drop and Convert
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 DAW, sequencer or audio editor
• turn the selection into an mp3 file. (or m4a)
• split interleaved stereo files into separate .L and .R file sets or vise versa
• convert to m4a and attach it to an email in one go.
• export to WAV (BWF, Broadcast Wave), mp3, or m4a (MPEG-4 audio).

Which formats can it handle?
All of them. Snapper opens over 50 sound file formats. That includes compressed files, split stereo, 192 kHz, 5.1 surround files, cds and videos containing audio. Snapper shows loops, markers, timestamps, regions, BWF annotations, even album covers. You name it, Snapper can handle it.

Finder
Snapper follows your file selection in the Finder. It shows a wave form as soon as you select an audio file.

Pro Tools, Nuendo, Logic, Cubase, Live.
You can drag (selections from) files directly to the cursor of your sequencer or audio editor.

Snapper loves SoundFX
Snapper now adds an informer that communicates all metadata within WAV files to MacOS Spotlight, so you can search and find Sound FX metadata in the Finder. This includes, BEXT, Copyright, creator, annotations, comments etc.

Universal Category System logo On top of that Snapper embeds the Universal Category System so you can look for synonyms and category explanations. Snapper displays the entire category and subcategory names, rather than their abbreviations.

Requirements: OS X 10.5 or later
