Just wanted to create an issue tracking this.
Am also curious if there is any active work on this?
Thank you!

Bit of a novice here, but it looks like the sampling rate and total number of frames are both available in CodecParameters for the track, but I have no idea how many samples / packet there are, or how to find that information. If anyone else knows how to get that, though, an implementation should be pretty trivial (samples_per_frame * n_frames / sample_rate = length in seconds)

Not all formats have streams where each frame has the same number of samples. E.g. in vorbis the number can vary from frame to frame.

I needed this as part of #513. I implemented it following the suggested approach in the symphonia documentation

Available nowadays.
