It is certainly possible to combine STFT with fast convolution in various ways. But doing so imposes significant overhead costs and constrains the overall design in strong ways. For example, this approach: > On Mar 9, 2020, at 7:16 AM, Spencer Russell wrote: > >  > if you have an KxN STFT

I think we're mostly on the same page, Ethan. Though even with STFT-domain time-variant filtering (such as with noise reduction, or mask-based source separation) it would seem you could still zero-pad each input frame to eliminate any issues due to time-aliasing. As you mention (paraphrasing),
