HTML5 audio player has problems with large audio files. This causes delayed playback and syncing problems with the text.

The following was found to help with playback without compromising quality:

Use a lossy file format (like mp3)
Reduce bitrate and sample rates to 16k
Reformat to a constant bitrate
Convert to mono

It would be better to do all of this in the browser once a user uploads audio, e.g., using https://github.com/Kagami/ffmpeg.js
