3rd Party Plugins - (fb2k) / Re: ReplayGain DSP - Alternative ReplayGain implementation by Case
Last post by Case -
New version released where the "positive gain" term is changed to "volume increase" as the option now takes both the gain and the target playback level amplifications into account.

There is now also advanced config setting at 'Preferences' -> 'Advanced' -> 'Playback' -> 'ReplayGain DSP' to control maximum allowed gain value with the realtime scanner. It now defaults to +20 dB, range is 0 to 100 dB.

And the peak compress clip prevention method was adjusted, it can now be enabled even for tracks that have unknown peaks (like Opus files with just tags).

Hello!
Is something broken with WilB Biography 1.4.2?
New artist photos won't show up, if I download and add artist pictures manually all is OK.
Wikipedia, allmusic, last.fm text works.

Thanks and best regards

Sorry, is "Mainconcept" the encoder?
Mainconcept is the company that developed the encoder. Was that really not clear?

The encoder is most probably proprietary, so if you want to know how they call it you'd probably have to contact them and ask.

Also, how can I run ffprobe from ffmpeg.exe?
I don't know if you can, ffprobe is a separate binary. But just to display the metadata from earlier it is enough to do:
Code: [Select]
ffmpeg -i "DST-EndoLoop.mp4" -vn -an -f null -

Thank you very much.

I just tried this, let's call it version 5:
Code: [Select]
static double apply_filter(float* A, float* B, int num_taps)
{
int i = num_taps - 1;
float sum = 0.0;

do {
sum += A[0] * B[0] + A[i] * B[i] + A[1] * B[1] + A[i - 1] * B[i - 1];
A += 2; B += 2;
} while ((i -= 4) > 0);

return sum;
}
In MSVC, regardless of settings (AVX2 or not, fp:fast or fp:precise), it has similar speed as version 3 and similar quality as version 4, while version 3 has obviously lower quality and version 4 has obviously slower speed. However in mingw64 and -Ofast (AVX2 or not), version 5 is slower than version 4 albeit they have similar quality.

So MSVC benefits from having 4 items in the same line, mingw64 does the opposite.

MSVC v3
F:\Programming\art-msvc\x64\Release>art-msvc-v3 -q -y -4 -r76543 1.wav 2.wav
8367
F:\Programming\art-msvc\x64\Release>art-msvc-v3 -q -y -4 -r44100 2.wav art-msvc-v3.wav
4852

MSVC v4
F:\Programming\art-msvc\x64\Release>art-msvc-v4 -q -y -4 -r76543 1.wav 2.wav
10562
F:\Programming\art-msvc\x64\Release>art-msvc-v4 -q -y -4 -r44100 2.wav art-msvc-v4.wav
6080

MSVC v5
F:\Programming\art-msvc\x64\Release>art-msvc-v5 -q -y -4 -r76543 1.wav 2.wav
8418
F:\Programming\art-msvc\x64\Release>art-msvc-v5 -q -y -4 -r44100 2.wav art-msvc-v5.wav
4881

Magenta and white are v3 showing lower quality, the others are v4 and v5 which are similar. Notice the two v3 results have 0.00001% THD and 0.00003% IMD+N. The figures are low, but still worse than v4 and v5.
