...the output for the filter-based and block-based resampler at different qualities at http://www.mumble.info/resamp/ The resampling was 96khz => 44.1khz. "chirp.png" is the original (unresampled) "perfect.png" is the result of a FFT/chop/iFFT of the whole file as one. "filter0.png" to "filter10.png" is the "normal" resampler at different quality levels. "block+X.png" is the block-based resampler with X samples overlap (and 960 samples (10ms) base block size). Note that block+0 and block+96 are not legal values for the resampler, they...

...om John, he thinks filter expressions should be emitted into the body of the function with the try, rather than being outlined by the frontend. Instead of having the frontend create filter functions, we would use labels in place of typeinfo. The IR would look like "landingpad ... catch label %filter0 ..." instead of "landingpad ... catch ... @filter_func0 ...". There would be a backend pass similar to SjLjEHPrepare that would outline the filter function and cleanup actions. Once we do the outlining, there is no turning back, because the outlined function has to know something abo...
