AudioUtils and Waveform Seekbar
Browse files Browse the repository at this point in the history 
- Created AudioUtils for processing audio messages
- Created Waveform Seekbar, for visualizing a FloatArray
- Time limit of about 5 seconds, else shows regular seekbar
- Also made mediaPlayer smoother
- Fixed time discontinuity bug when playing voice messages, but only on API 28 or higher
