I’ve seen a few implementations in matlab, but this describes things the stft / istft procedure at a higher-level:

I’m interested in this and am wondering if other people would be interested in this.

Yeah, it would be useful to have istft. There’s an implementation in @jongwook’s [MusicProcessing.jl](https://github.com/jongwook/MusicProcessing.jl) but it’s somewhat audio-specific (it uses the samplerate-aware buffer types from SampledSignals). There was also a [PR to DSP.jl](https://github.com/JuliaDSP/DSP.jl/pull/85) with an implementation - looks like it’s maybe just stalled?

It could probably use a review and rebase,
