Waveform can currently only be rendered for a short section (now set to 30 sec), because rendering longer will take a lot of time. Need to find a way to quickly render a waveform of a long track. (hours long)

• Rendering 30 seconds at a time shouldn't prevent you from still displaying the already rendered waveform. It's fine if a 2 minute song renders in 4 sections
• Make waveform bigger (With audio files, the entire space kept for video is wasted real estate. The audio waveform could be much bigger and easier to see) req: audio waveform with zoom and thumbnails #6
• a bit-perfect waveform editor in the split-and-join scheme for those who just want to edit the audio bit-perfect waveform editor #736
• allow showing waveform at the same time as thumbnails Persistent/inconsistent settings below timeline [Show waveform/thumbnails/keyframes] #843 / allow scan/rendering the entire waveform when I first load the file Option to Allow Rendering of Entire Waveform At Once? #1193
• Rough full-timeline waveform at 1x, finer waveform when zooming in Improve waveform #260 (comment)
• allow choosing which track (stream) to render waveform from Audio waveforms #1590
• allow showing a bigger waveform and video at the same time:
  • either allow increasing the height of the small (lower) waveform
  • OR allow a split view of the big waveform and the video
• Find a better way to render an arbitrary portion of a file
• The full-height waveform view is currently not linked with the bottom editing segment. If they can be linked together, it will greatly facilitate waveform-based editing. For example, when splitting a segment, the waveform graph should also be split into two segments; when deleting a segment, the corresponding section on the waveform graph should also show as deleted (with dark background or diagonal pattern).
• allow showing channels as separate or combined (currently only separate is supported)
• if multiple active audio streams, mix all audio streams+tracks together in waveform?
