Oh I forget the reassignment and NC (neighboring components) method exists to make FFT-based spectrum and spectrogram look much sharper in both time/frequency axis (though with caveats of for the former, having point cloud-like appearance especially on lower frequencies and for the latter, a rectangular window and possibly zero-padding works best though for both, the FFT size parameter still makes sense considering there is still a time/frequency resolution tradeoff in a form of window length), which can greatly improve the spectrogram display but is it worth adding these to foo_enhanced_spectrum_analyzer component?
BTW, I think the smoothed spectrum still have poor time resolution on higher frequencies in log2 frequency scale with FFT sizes like 32768, 65536, or even higher samples assuming it is just a post-processing step (considering just decreasing the Q value can similarly produces a smoothed spectrum but with improved time resolution, but it only applies to IIR/FIR filter bank anyway)
It would be nice if you could consider a silent mode. I have assigned the function to a keyboard key and don't need the result dialog. A progress bar would then be sufficient.

Merge it with the other - or maybe kill that one. Because this thread is more informative - here one can find a why don't you use G.729 instead. If you need it at all, or just are of the kind who insists that everyone should spend their time on any and every idea you may come up with.

Proper audio analysis have full resolution at log2 frequency scale. But here I find amateurs coding plugins with low and quantized output only. Hard to learn here anything new.

Hi, If I am creating a thread in the wrong place, please moderators move it. I have a problem with one of the CAF files. I'm using a component by nu777 foo_input_caf and all files play fine otherwise. VLC Media Player plays it, but not completely. It may be a component error, but I don't rule out another error. Maybe this file is corrupt. File integrity verifier shows

Despite being earlier against this, I have now uploaded hopefully all of the 64-bit conversions I have made of the seemingly abandoned components. The conversions can be found at the bottom of my personal component site here: https://foobar.hyv.fi/.
Thanks for this initiative and all the work you do for the community within the HA forum, Case!!

QOA is a Quite OK codec for me , but it's not too transparent. I made an ABX with Foobar2000 and got 16/16. Here's the link to the drive folder:
Maybe QOA can be transparent at higher sampling rates but looks like it's not transparent at 16kHz etc. I hope a 4-bit version will come (1-bit and 2-bit versions were came) for storing high quality audio with it, but looks like 3-bit is still a good compromise between filesize and quality for most circumstances.
