That certainly is a strange problem. I can't offer a solution to it per se, but I recommend installing foo_input_vgm, as it is more up-to-date and feature-rich. Hopefully it would fix your problem.

ACTUALLY, IT WORKED! I just have to select the correct sound chip to mute the channels freely! Thank you so much! Have a great day!

Not sure, what you're talking about.
This APE file sample plays fine for me in 1.4.
TAK should also work, at least it did back in 2017 (provided via ffmpeg) according to the Android changelog.
Would have tested it as well but there don't seem to be any sample files on the net and I'm too tired to convert some on my own.

I can understand probably why .tak can't be supported, but I didn't expect .ape to be ineligible. Many existing windows components simply don't work? Thanks.

FLAC / Re: FLAC v1.4.x Performance Tests

Last post by Porcus - 2023-10-02 22:15:06

8192 beats 16384 size-weighted in my tests on upsampling those 38 CDs, but it varies quite a lot. Medians could very well tell a different story. I messed up something and it is still running, but I can report on those two block sizes at least.

Using -A "subdivide_tukey(3);blackman" on everything, then
** In overall size:
At 96 kHz, -b8192 beats -b16384, and -eb8192 beats -eb16384.
At 192 kHz, same happens.
At 384 kHz, -b8192 beats -b16384 by around 0.12 percent, but -eb16384 beats -eb8192 by around 0.18 percent.

192 kHz, let's look into that further: No -e here.
* Classical music benefits from larger blocksize -b16384, 12 albums to 2; all except harpsichord and (near-zero) Cage's percussion works. Total impact 0.32 percent (not percentage points!), varying from -0.15 (harpsichord) to 0.63 percent (Bruckner, vocals)
Median impact = 0.37 = median absolute value impact.
But then the rest:
* The heavier music: -b8192 wins by 7 albums against 3, switching sign on impact to signify that:
Total impact -0.14 percent, varying from -0.71 (Laibach, biggest benefit for -b8192) to 0.24 percent (Gojira, that benefits from 16384).
Median impact = -0.24. Remove the sign for median absolute value impact.
* The others. -b8192 wins by 9 albums against 5
Total impact -0.28 percent, max benefit from -b8192 is -1.31 percent (Wovenhand, in this release that is singer/songwriter) and then -0.99 (Sopor Aeternus, that is something completely different: darkwave) - and on the other end, benefiting most from larger blocksizes are the jazz albums: 0.41 percent for both Davis and Johansson. Those were near-mono before dithering I think.
Median impact = -0.32 percent. Median absolute impact: 0.38.

For those who did not follow the previous discussions, I am talking about optimizations for >=4x upsampled data, so the parameters listed above are not suitable for encoding "real" hi-res files.

... but who knows how many hi-res files are "real".

Thanks for the information. I hope the new feature will be available very soon.

General Audio / Re: AI language models can exceed PNG and FLAC in lossless compression, says study

Last post by C.R.Helmrich - 2023-10-02 19:30:04

Alright then, in that case I'll assume they did not use dither, just simple rounding. Then, many speech pauses will turn into digital silence, making FLAC compression to ≈30% of the WAV size possible, I guess.

Edit: To simulate this, I manually zeroed out the speech pauses in your librispeech-8bit.flac and, after re-FLACing, the compression ratio improves from 36.3% to around 32%, as expected.

And the fact that LZMA2 compresses a bit better than FLAC can probably be explained by the frame-wise header overhead in FLAC, which turns significant with file sizes as small as those which you reported.

Chris

P.S.: And compared with the input media (audio, color images), none of what they do is actually lossless then. Still wondering about the 16.4%, though.
