Here's another 1.4.1 compile with newer GCC (12.2.0). Over here it's faster than Xiph build even with -p.
Seems like for my Ryzen 5000 this compile is still the fastest. Is it a problem to build the metaflac binary the same way?
I still and others maybe also use it for applying RG.
Is troll-adiposity coming from feederism?
With 24bit music you can listen to silence much louder!

BTW, it is still not possible to encode some channels layouts (e.g. 4.1) without option --channel-map=none. And this option is not documented still not in https://xiph.org/flac/documentation_tools_flac.html  nor --explain.

Out of curiosity:
For multichannel FLAC-in-Matroska, the channel mapping sits in the Matroska container's metadata, and so as long as a player is able to handle both
(1) multichannel Matroska in the first place, and
(2) FLAC decoding in the first place,
then it will - unless terribly designed - handle those files even if it was never updated to understand FLAC's "new" WAVEFORMATEXTENSIBLE tag override?

Hey @Case , had to create an account here to maybe help a little bit with this

I run Gentoo with LTO and it has been a blessing, maybe check https://github.com/gentoo-mirror/lto-overlay it shows a lot of tweaks to the CFLAGS to make a "better" binary, also, check https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html for -march= releases for different archs?

A few snippets:

Code: [Select]
FLTO="-flto=${NTHREADS}"

#FLTO is of the form -flto[=n] where n is the number of threads to use during linking.
#It's usually a good idea to set this to the number of hardware threads in your system
#You may also set this to "auto" to have gcc determine optimal number of cores (GCC 10+)

GRAPHITE="-fgraphite-identity -floop-nest-optimize"

#GRAPHITE contains Graphite specific optimizations and other optimizations that are disabled at O3 but don't influence the compiler's judgement.
#Since GCC 8.1.0, -ftree-loop-distribution is enabled by default at -O3
#NOTE: To use graphite, make sure you have gcc compiled with graphite support (add graphite to your USE).  Otherwise GCC will complain!

IPAPTA="-fipa-pta"

#IPAPTA contains -fipa* opts that are disabled by default in GCC.  These are interprocedural optimizations.  For now this is only -fipa-pta.
#This option increases compile times, but can potentially produce better binaries, especially with LTO.
#Essentially, it allows the compiler to look into called function bodies when performing alias analysis

SEMINTERPOS="-fno-semantic-interposition"

#With -fno-semantic-interposition the compiler assumes that if interposition happens for functions
#the overwriting function will have precisely the same semantics (and side effects).
#Similarly if interposition happens for variables, the constructor of the variable will be the same.
#The flag has no effect for functions explicitly declared inline (where it is never allowed for interposition to change semantics) and for symbols explicitly declared weak.

NOCOMMON="-fno-common"

# This option only affects C code.  Only non-conformant C code needs -fcommon, which is enabled by default.  Clear Linux leaves this flag off by default.
# This is enabled by default with GCC 10 and is kept here only for documentation purposes.  Use `-fcommon` to restore
# GCC 9.x behaviour and below.

SAFEST_FAST_MATH="-fno-math-errno -fno-trapping-math"
SAFER_UNSAFE_MATH_OPTS="-fno-signed-zeros -fno-trapping-math -fassociative-math -freciprocal-math"
SAFER_FAST_MATH="${SAFER_UNSAFE_MATH_OPTS} -fno-math-errno -ffinite-math-only -fno-rounding-math -fno-signaling-nans -fcx-limited-range -fexcess-precision=fast"

#These are flags left off by default that we're planning to start using.  Clear Linux uses these in lieu of full -ffast-math optimizations
#They DO break compliance with ISO C++, so we'll be careful about introducing these.
#Relevant discussion: https://gcc.gnu.org/ml/gcc/2017-09/msg00079.html
#We may end up just going full -Ofast, with exceptions done in the usual way.

DEVIRTLTO="-fdevirtualize-at-ltrans"

#This allows GCC to perform devirtualization across object file boundaries using LTO.

NOPLT="-fno-plt"

#This option omits the PLT from the executable, making calls go through the GOT directly.
#It inhibits lazy binding, so this is not enabled by default.  If you use prelink, this is
#strictly better than lazy binding.

In addition to this, if you use an Intel processor (Sandy Bridge or later), you may want to enable -falign-functions=32 in your CFLAGS.

Some of this may already be used and/or maybe you have tried it already, but who knows :D

I thought it was more applicable to post here rather than the FLAC v1.4.x Performance Tests thread.

Whilst most (all?) reports I've seen of flac v1.4.1 (and v1.4.0) show a decrease in bitrate and filezsize (albeit mostly small), I've had a few albums that I've re-encoded to 1.4.1 showing a slight increase. This is using the flac.exe that is in the foobar Free Encoder Pack 2022-09-23, using foobar (obviously) and all encodes have used the -8 setting (with no other options added).

It's not really an issue for me, but thought I'd share it.

Here's three examples:

The Prodigy - Music For The Jilted Generation:
v1.3.2 20170101: 512 MB (537 233 371 bytes) | 909 kbps
v1.4.1 20220922: 512 MB (537 590 184 bytes) | 910 kbps

Andy C - Nightlife 2 (A Drum And Bass Odyssey)
v1.3.3 20190804: 956 MB (1 003 192 746 bytes) | 967 kbps
v1.4.1 20220922: 957 MB (1 003 692 777 bytes) | 968 kbps

Pendulum - Hold Your Colour:
v1.3.3 20190804: 563 MB (591 035 369 bytes) | 982 kbps
v1.4.1 20220922: 564 MB (591 536 971 bytes) | 982 kbps

Doc Scott - Artcore 2 - The Art Of Drum & Bass
v1.3.2 20170101: 514 MB (539 818 208 bytes) | 903 kbps
v1.4.1 20220922: 515 MB (540 149 290 bytes) | 903 kbps

As you can see it's minor; just a 1 kbps increase and 0 in the last two, although with still a slight filesize increase.

These are all Drum & Bass / Jungle/ Breakbeat / "Hard" Electronic albums. Maybe the complexity of such music is the factor here??

As I say, it's not a critique, but simply to give some balance to there thus far being a seemingly overwhelming reduction in reported bitrate and filesize (using the same settings) that I've seen.

Out of curiosity, what happens if you use 1.4.1 with the old windowing functions?
-8 -A "tukey(5e-1);partial_tukey(2);punchout_tukey(3)"

For -7 and -8, there are slight changes in the windowing functions used to come up with the predictor. Those changes were made for speed (counteracting the slowdown due to double precision), by tweaking them get some calculations recycled.
There will every now and then show up signals where, by chance, the old ones made a better job. Also, flac works by "guesstimating which one is best and then spending time on that", so it may by chance go for the wrong one. Which should not make for big impact.

different toc, but still.

wrt non-audio data, do you mean tags? And if so, tags don't affect the bitrate surely?

I checked the files with another software (MediaInfo), the reported bitrates are consistent with foobar. The encoded files contain no tag / metadata / pictures.

Short answer: tags don't affect bitrate.

Longer answer: foobar2000 tries to calculate "audio-only" bitrate, and as far as I know it is reliable when it comes to FLAC.
(Other applications may consider the whole file - which is "more relevant" if you are asking what it takes to stream it, for example).

From my observation there is nothing particularly special about this disc.
[1] Setting -b above or below 4096 increases bitrate.
[2] -8 -A subdivide_tukey(3/125e-3) seems optimal.

Converted using foobar with -8 setting except for the "tukey..." ones.
Mediainfo and foobar report the same bitrate for all.

Will keep an eye on any re-encodes to 1.4x I do, but looks all ok

Re: FLAC v1.4.1 (Release)

Reply #44 –
No, only ever used -5 (many many years ago) and -8 with flac.exe from the foobar encoder packs.

I don't have the "original" 1.3.2 & 1.3.3 encodes of the Prodigy and Andy C album that showed 1kbps less (I deleted them). And you can see the various re-encoding results done this morning.

If anything pops up that seems odd in future I'll look into it and if necessary post here. But I think it's all ok.

This is apparently not any "1.4.x" thing, but:

-0p, -1p, -2p.  Is there any reason whatsoever that they should take longer time than -0, -1, -2, when -p has no (other) effect?
Because they might very well spend fifty percent more time.

Tested this because there are other scenarios where I just don't understand the cost of -p (rather, the differences in cost).

I am quite confident that they do here. Tested on three computers:

* New computer tested, this is one where -p makes the least of difference it seems. What I put to work at bedtime: a .bat file working on 20 GB (compressed!) of individual-track .flac files, first a non-timed -3pf to warm up the CPU and then 1.3.1 and 1.4.1 producing timings in the following order, manually rounded off from timer64's "Global time".
-0: 327 and 270
-0p: 373 and 364
-2: 346 and 309
-2p: 405 and 401

* Dell laptop ran yesterday, same computer as previously; this with 1.4.1 only:
Ran a warm-up, then a loop compressing the same album ten times with -2 and then ten times with -2p and rinse and repeat, alternating with or without -p until heated up and fan was running and times had stabilized. Typical times:
-2: 4.8 seconds (last twenty varied between 4.796 and 4.885, no worse than that),
-2p: 6.8 seconds

* Acer consumer laptop with Ryzen CPU, same as previously used in testing, same test as on the Dell but ran on a different album because "just pick random one", not my computer:
-2: 8.9 seconds
-2p: 13.6 seconds

I obtained similar results on x86_64 Ubuntu 22.04 and Aarch64 Debian. So, can't replicate.

Re: FLAC v1.4.1 (Release)

Reply #49 –
Tested again and found something even more shocking.
* Output to terminal window takes a hell of a lot of time - and differs over -p or not.
In both cases I ran -0 and -0p alternating, and just to be sure about the timings, I threw in an echo:| time after every -0p in addition to timer64.

Code: [Select]
C:\tmp>echo:|time & for /l %l IN (1,1,10) DO (c:\bin\timer64 c:\bin\flac-1.4.1-win\Win64\flac.exe testflacfile.flac -0f & c:\bin\timer64 c:\bin\flac-1.4.1-win\Win64\flac.exe testflacfile.flac -0pf & echo:|time)
The current time is: 12:07:12,39
Enter the new time:

C:\tmp>(c:\bin\timer64 c:\bin\flac-1.4.1-win\Win64\flac.exe testflacfile.flac -0f   & c:\bin\timer64 c:\bin\flac-1.4.1-win\Win64\flac.exe testflacfile.flac -0pf   & echo: | time)
