FLAC / Re: FLAC v1.4.x Performance Tests
Last post by Porcus -Is there any particular reason why 64-bit flac.exe should be so much faster than 32-bit?
Could you release a new version with a "-high" argument which gets a bit higher compression ratio than default but 25-50% slower compression and decompression speed?
ahaha, wow, TSAC-encoded files look painful to listen to!

Yes, smoothing will be part of the new version:Surely, IIR filter bank can be made wider (lower Q parameter as there is no FFT size parameter for this filter bank-based analysis) while having larger number of bands per-octave to get a smoother spectrum with improved time resolution or responsiveness on lower frequencies (as we can't have narrow bandwidth while having good time resolution on lower frequencies at the same time obviously), try it out yourself by tinkering with "Bandwidth" parameter on my own AudioWorklet-based filter bank spectrum analyzer project
This plugin looks nice in my foobar2000.Thanks!
Feature request: Show more details on higher frequencies with "Low detail mode" switch, something like this:Yes, smoothing will be part of the new version:
