I've very long wanted something like this! Basically like a CyberChef ( https://gchq.github.io/CyberChef/ ) but for audio. I work in digital speech processing and often work with audio codecs and it would be very helpful to have an online tool which lets you apply multiple filters to some audio.
What I'm missing after trying out Sawtooth is the interactivity of CyberChef. Basically trying out a few filters, one after the other, showing the intermediate results for each, and some frequency analysis on it, and hearing the results. Can audio filters be applied in the browser for instant-feedback to hear the audio 'live' (like CyberChef auto-bake) like it can be with text?
And some conversions would be really great as well, like being able to apply various encodings: Treating the samples as a-law encoded and applying an a-law decoding pass on it.
