Description

This is a feature that's also request on the jellyfin server itself as well to help integration with 3rd party clients.

It would be great to see a waveform progress bar, like some other players do it. Until spectral data retrieval is implemented on the jellyfin api, this could work for downloaded tracks already.

Example of how it looks in plexamp :

Research direction
Investigate the current player UI implementation in Finamp, specifically the progress bar widget (likely in the player screen). Explore available Dart/Flutter packages for audio waveform visualization, such as flutter audio waveforms or just waveform. Check if the Jellyfin API provides any spectral data; otherwise, focus on local file waveform extraction using audio processing libraries. Review issue comments and linked issues for any implementation ideas or blockers.
