Adjusted the area in which the waveform gestures work (enlarged it to encompass the whole waveform)
Got media player hooked up so that it only plays the portion of the audio file corresponding to the current onset. Next steps: annotation...
Creating buttons to mark onset locations in two ways: 1) auto-create based on onset location in the current view (not yet working that well…there's an offset), 2) double-tapping the waveform (works pretty well…next step would be to add gestures to the button for selecting, deleting, expanding/minimizing, etc.)
