I want, in my Ionic app, to fulfill these two requirements:
- visualize the audio waveform from the audio stream of pre-downloaded short (~30secs) video.
- Visulze the recorded audio waveform when users record by mobile microphone. It is nice-to-have if real-time.
I was considering to use libs, such as https://wavesurfer-js.org/, but wanted to know in advance if it is viable and if somebody has done it before.
