SONAR’s AudioSnap engine and tempo analysis features give you unprecedented rhythmic and tempo control over your audio. Employing sophisticated transient detection technology, the AudioSnap engine automatically analyzes all recorded and imported audio files for rhythmic content to determine where the beats are in the music.AudioSnap is completely non-destructive, similar to Groove clips and V‑Vocal clips. AudioSnap, V‑Vocal, and Groove clips are mutually exclusive. Groove clip markers are typically placed at a zero-crossing point before a transient; AudioSnap transient markers are placed where musical changes occur, but may not be exactly at a zero crossing.AudioSnap is not a single feature, but rather a collection of different tools that can be used for different tasks. The AudioSnap palette ties it all together in a task-oriented layout.Figure 195. The AudioSnap paletteAudioSnap works by finding the transients in audio clips. Transients are the areas in an audio clip where the level increases suddenly. These make good locations to shrink, stretch, or split a clip, without changing its sound quality too drastically. SONAR contains a variety of high-quality stretching algorithms for different kinds of material. You can choose a lower-quality algorithm for real-time playback of your edits, and then choose a better algorithm for mixdown or bouncing to track (see Algorithms and rendering).SONAR lets you define the default online and offline algorithms via the AudioSnap palette, and you can override the default algorithm(s) on a clip-by-clip basis.
Note: The online algorithm is for preview purposes only during playback. The final audio quality will be greatly improved after the offline algorithm is applied during mixdown/export.The transients also make it possible for SONAR to calculate a clip’s tempo map (see Editing a clip’s tempo map).Figure 196. Audio clip.Figure 197. Audio clip showing transient markers.AudioSnap finds transients automatically, but the transient markers don’t always appear exactly where you might want them for the kind of editing you want to do. You can edit the markers by moving them to new locations, adding markers, filtering out markers, deleting markers, and promoting markers (protecting them from being filtered). For information about editing transient markers, see Editing transient markers.
