Integrate bbc/peaks.js for waveform display #212
Description
Is your feature request related to a problem? Please describe.
Sometimes when transcribing long audio files there are long pauses. From an ASR (STT) standpoint, no speech regions may be detected, but there may be a muffled word that was missed. A quick view of the waveform can help pick out audio regions to listen to.
Describe the solution you'd like
Toggle display of the waveform below the time bar
Describe alternatives you've considered
Separate waveforms per audio channel would be great.

👋 @NickRuiz
Throwing another option into the mix,
Replace the progress bar / or have an alternative progress bar in storybook using wavesurfer-js
The issue I see with using
peak.js(and might be wrong coz I am not super familiar with the library) is that it says in theREADME:And if it does need a backend to generate the waveform data it would make it harder to keep it self contained as part of the component.

Good point. Thanks for sharing a few more-compatible alternatives.

@NickRuiz I thought you might find this interesting / useful bbc/stt-align-node if you are looking for a way to review results of STT?

Our transcribers/annotators use waveform display to quickly find the beginning of new "paragraphs", etc. Depending on how the ASR transcript is generated/segmented it might not be apparent when two adjacent words are separated by a long period of silence.
