4 years ago I'm not as familiar with audio processing, as with image processing. Not sure, that MP3 quantization is alike. I found research work here, that maybe do this thing, maybe not. But can't find a link to read it for free to be sure.

We will help. Torrents are everything. The topic is important!

4 years ago Look like it's about smaller lookup tables and performance, at same quality.

4 years ago I will not prompt. I'm used to sndfile. For me, MP3 is gibberish for now.

4 years ago Try to ask for this here. I'm not sure if this is possible, because I have no experience with MP3 decoders.

4 years ago Ok.
Interested in MP3 DCT Quantum Smooth based on madplay (https://www.underbit.com/products/mad/) or mpg123 (https://www.mpg123.de/).
I immediately warn the obvious answer: I know about filter banks. I don’t propose to mess with “filter banks” for dequantization, but I suggest using other information.
“Volume War” in combination with “filter banks” in any MP3 without additional regulation (REPLAY_GAIN) leads to clipping. It is this fact that I propose to use for dequantizing MP3.
I’m not sure that the result of dequantization can be saved in MP3 (even 320kbps), but the utilities I have specified allow to save the result in WAV.
PS: This time expected
library + tool.
