Here's a test (using 160px height):

Standard track:

Swipe on right channel:

Sinus on left channel:

Song with low volume:

Will this work?

Edit:

A last one in dark theme, showing differances in left and right channels:

>>I guess you calculate the waveform from the unfiltered file - is it possible to use (album) gain?

It does not seem like that, since the gain is applied in real-time. (Not know during reading of the audio-data)

>>Once again my question: do you render the waveforms / spectrogram every 50ms?

For the waveform yes, since it is very quick. For the spectogram no, since it is slow.

I will probably add a setting for the spectogram which controls the quality of the spectogram (FFT size).

Speed results for spectogram (initial render or when size is changed), startsize 1920*160 pixles:

• FFT 16384 bytes:1265ms
  
• FFT 8192 bytes: 735ms
• FFT 4096 bytes: 453ms
• FFT 2048 bytes: 297ms
• FFT 1024 bytes: 235ms
• FFT 512 bytes: 188ms

This might be a possible future updated, when everything else is closed and considered as working.

Fixed in #528
