[Feature Request] Playback waveform

[Asheq]

When playing back audio, the app could show the waveform (volume visualization) of the track, similar to what is shown during recording.

I find this useful to quickly identify periods of silence and move past them.

I like the way that this app implements it: https://play.google.com/store/apps/details?id=com.dimowner.audiorecorder&hl=en_US&gl=US In that app, the visualization itself can be slid/panned left and right to move through the track. That feels much nicer than trying to move the little circle on the line.
