Class AFOnset

AFOnset (Audio File Onset) encapsulates a techniques.AudioFile instance, dividing the underlying source audio file into three regions delimited by onsetSeconds and releaseSeconds.

      onsetSeconds
├──────────┘         releaseSeconds
├───────────────────────────┘
├──attack──┼──────body──────┼─────────decay─────────┤

Using this technique in a score shifts the resulting audio item to the left on the timeline such that the audio file onset coincides with the the start of the event. This is useful for audio samples that have an "appoggiatura" that "leads in" to the musical onset of the sample.
