Extracting Numerical Data from Audio

RichardKnott's icon

Hello,
Basically, I'm trying to find a way to extract the maximum amount of numerical data from an audio stream, starting with peakamp readings at specified frequency bands.
Using multiple filtergraph objects with set bandwidths seems like the long way round, so if anyone could describe a better way of doing this I would be most grateful!

Thanks,

Rich.
