Description
1st commit:
Whenever audio attachment is playing there are a lot of unnecessary work done in AudioWaveformProgressView.redrawSamples. On every audio progress update there are paths recreated for playedShapeLayer and unplayedShapeLayer. In my solution I draw unplayedShapeLayer and playedShapeLayer once and further apply layer mask to playedShapeLayer to show progress.
2nd commit:
AudioPlayer triggers update UI progress 20 times per second with Timer. I replaced timer with CADisplayLink which allowed to reduce updates number per second and improve animation smoothness.
Changes in 2 commits reduced CPU usage from 13% to 5% on my iPhone 12 (17.4.1).
