@korth as mod: I don't want to "shield myself against my own mistakes" here, but if you think it is OK - it being on a previous page with misleading numbers right in user's face - would you maybe please moderate in an extra first line in Reply #13 like e.g. the follows:
Mod note: Porcus facepalms and suggests to read Reply #28 for correction
Anyway, after having tried ffmpeg -threads this and that and around, I found the mistake not in the ffmpeg command, but in the flac command. It is even in the codebox, where flac was run with options -fo NUL ... without "-d". So it spendt time re-encoding to FLAC. Thank you to @ktf for spotting the anomaly.
Here are some hopefully more sane numbers, where reference FLAC (1.4.2 was used ... for dumb reasons) beating ffmpeg -threads 1.
Decoding times on SSD to NUL, the 1.060 seconds means 1774x real-time
Encoded with -0b65535 --no-md5 --lax
1.060 s ± 0.009 s flac (1.4.2)
1.278 s ± 0.008 s ffmpeg -threads 1
0.842 s ± 0.007 s ffmpeg -threads 2
0.591 s ± 0.030 s ffmpeg -threads 3
0.522 s ± 0.010 s ffmpeg -threads 4
0.506 s ± 0.012 s ffmpeg -threads 6
0.538 s ± 0.007 s ffmpeg, default threads (detects all eight)
Encoded with -0r0 --no-md5, reference FLAC single-threaded beats ffmpeg -threads 3
1.144 s ± 0.015 s flac (1.4.2)
1.799 s ± 0.005 s ffmpeg -threads 1
1.642 s ± 0.005 s ffmpeg -threads 2
1.163 s ± 0.007 s ffmpeg -threads 3
0.998 s ± 0.014 s ffmpeg -threads 4
0.981 s ± 0.015 s ffmpeg -threads 6
1.019 s ± 0.012 s ffmpeg, default
Encoded with default -5
1.552 s ± 0.011 s flac (1.4.2)
1.967 s ± 0.006 s ffmpeg -threads 1
1.290 s ± 0.012 s ffmpeg -threads 2
0.899 s ± 0.008 s ffmpeg -threads 3
0.725 s ± 0.003 s ffmpeg -threads 4
0.654 s ± 0.052 s ffmpeg -threads 6
0.619 s ± 0.006 s ffmpeg, default
Encoded with -8pl32 -r8 --lax
2.056 s ± 0.019 s flac (1.4.2)
2.818 s ± 0.006 s ffmpeg -threads 1
1.746 s ± 0.029 s ffmpeg -threads 2
1.227 s ± 0.021 s ffmpeg -threads 3
1.038 s ± 0.003 s ffmpeg -threads 4
0.784 s ± 0.004 s ffmpeg -threads 6
0.739 s ± 0.013 s ffmpeg, default
Encoded with -8b16
5.476 s ± 0.034 s flac (1.4.2)
24.328 s ± 0.186 s ffmpeg -threads 1 <------- ooh bad
61.104 s ± 0.582 s ffmpeg -threads 2 <------- and the "even worse" starts already here!
61.290 s ± 0.501 s ffmpeg -threads 3
60.371 s ± 0.438 s ffmpeg -threads 4
60.236 s ± 0.709 s ffmpeg -threads 6
61.878 s ± 0.492 s ffmpeg, default
There is not much gained above 4 threads (this is a 4-core 8-thread CPU) except the 8pl32-etc. file.
Commands given:
flac <file> -ss -dfo NUL
ffmpeg -threads <T> -i <file> -hide_banner -loglevel error -f wav -y NUL

WavPack / Re: -h as the new default mode
Last post by Porcus -Old code snippets die hard - for example for Monkey's Audio (Ashland develops for JRiver), the last available chm help file had a screen where there was no "Insane", before it was removed as outdated in 2022 ...
And JRiver was first released in, *looks up*, 1998 - before FLAC.
FLAC -6? At 0.x , -6 was the default. Could have stuck.
Not recommending -hh? The WavPack manual still warns against it for legacy hardware players. There were some Rockbox'ed hardware players where -h would decode slower than Monkey's Fast, although -hh decodes lighter than any Monkey on desktop.

Last post by TF3RDL -- Vertical scrolling spectogram, aligned with the bars of the spectrum analysis on top.Finally, a sneak peek of combined spectrum/spectrogram visualization, which is I want for @Crossover's Enhanced Spectrum analyzer component
- Left/Right and Mid/Side level meters with configurable channel pair.BTW, this makes me want more Mid/Side visualizations (e.g. a Mid/Side peak/RMS meter and a M/S spectrum analyzer)

WavPack / Re: -h as the new default mode
Last post by shadowking -Like WV high was designed for low power devices to replace 'very high' which itself was reasonably fast.
Do they say anything for monkeys ? I bet -c2000 is recommended even though way slower than -hh of WV..
It can also be interpreted that wv 'fast' of flac -4 are not recommended , So why do these in the first place ! ??. Stupid.
Btw
I had a P3-550 pc years ago that handled all WV modes easily, all Monkey Audio modes except 'insane', Even moderate
optimfrog modes worked.

General - (fb2k) / Re: Play/Convert DSD Stream Files (.dsf)?
Last post by dewdude -PCM stores it's audio using samples that contain a number of bits that correspond directly to the amplitude of that sample. So you know a sample of 0XFF will be full-scale amplitude and 0x00 will be full scale the oppostite direction. Samples can be signed...yadda yadda...but with PCM you have bits that represent a sample level.
DSD doesn't have that. It's sample is a bit. DSD doesn't even store the position of the waveform....it stores the delta of the wave....and it does this by flipping a saw-tooth oscillator very very rapidly then low-pass filtering it. This is also called Delta-Sigma Modulation.
You've probably dealt with it without realizing it. Most DACs use the "oversampling" technique; which uses delta-sigma internally at higher rates. CD players in the 80s and 90s used oversampling like crazy. It should also be noted that when digitizing signals, they usually start out as delta-sigma before being decimated to PCM.
The "lossy" aspect is talking about bit-perfection through the chain...not perceptual quality. You can't decimate DSD to PCM anything and then back to DSD and get the same bits back. You'll get the same perceptual audio quality. You can't go PCM-DSD-PCM losslessly either.

Validated News / CD Drive Accuracy 2024
Last post by spoon -AccurateRip collects data from all drives, normally this is only used to verify a disc is accurate, but can be reversed to calculate which drives are the most accurate (as measured by lowest % inaccurate tracks), on the basis that people who have a drive would have the same number of damaged disks as everyone else, on average.
This test was previously run in 2022, 2019, 2016, 2014, 2013, 2012, 2010, 2009 and 2006, as time goes on more submissions give a greater meaning to the results, only drives with over 4000 submissions and 40 users are used.
