This moment was awaited for a long time, MPEG-4 lossless audio (ALS) specifications are now ready. Standardization were finalized recently and it was announced in Japan by the NTT company (source: here and in french)
MAIN FEATURES:
• Support for PCM resolutions of up to 32-bit at arbitrary sampling rate (including 16/44.1, 16/48, 24/48, 24/96, 24/192).
• Multi-channel / multi-track support for up to 65536 channels (including 5.1 surround).
• Support for 32-bit IEEE floating point audio data.
• Optional storage in MP4 file format (allows multiplex with video).

Full Version: MPEG-4 Audio Lossless: final specifications
I'm currently running a comparison between the freely available MPEG-4 ALS encoder and other popular lossless tools.
My table:
- MPEG-4 {default}
- flac 1.1.2 -8
- WavPack 4.3 -fx5
- WavPack 4.3 -x4
- Monkey's Audio 3.99 "fast" /-c1000
- Monkey's Audio 3.99 "normal" / -c2000
Files are my 150 reference full tracks (=16 hours of music), classical music only.

The comparison is meaningless without encoding and decoding speed. But I didn't find any decoder for measuring speed, and I'm running the encoding task on a laptop which is handicaped by a slow HDD. The comparison is just "informative".
EDIT: Monkey's audio bitrate were first wrong; they were edited one hour later. Sorry...
My table:
- MPEG-4 {default}
- flac 1.1.2 -8
- WavPack 4.3 -fx5

- Monkey's Audio 3.99 "normal" / -c2000

The comparison is meaningless without encoding and decoding speed. But I didn't find any decoder for measuring speed, and I'm running the encoding task on a laptop which is handicaped by a slow HDD. The comparison is just "informative".
EDIT: Monkey's audio bitrate were first wrong; they were edited one hour later. Sorry...

Usage: mp4alsRM16 [options] infile [outfile]
In compression mode, infile must be a PCM file (wav, aif, or raw format)
or a 32-bit floating point file (normalized, wav format type 3).
Mono, stereo, and multichannel files with up to 65536 channels and up to
32-bit resolution are supported at any sampling frequency.
In decompression mode (-x), infile is the compressed file (.als).
If outfile is not specified, the name of the output file will be generated
by replacing the extension of the input file (wav <-> als).
If outfile is '-', the output will be written to stdout. If infile is '-',
the input will be read from stdin, and outfile has to be specified.
General Options:
-c : Check accuracy by decoding the whole file after encoding.
-d : Delete input file after completion.
-h : Help (this message)
-v : Verbose mode (file info, processing time)
-x : Extract (all options except -v are ignored)
Encoding Options:
-7 : Set parameters for optimum compression (except LTP, MCC, RLSLMS)
-a : Adaptive prediction order
-b : Use BGMC codes for prediction residual (default: use Rice codes)
-e : Exclude CRC calculation
-f#: ACF/MLZ mode: # = 0-7, -f6/-f7 requires ACF gain value
-g#: Block switching level: 0 = off (default), 5 = maximum
-i : Independent stereo coding (turn off joint stereo coding)
-l : Check for empty LSBs (e.g. 20-bit files)
-m#: Rearrange channel configuration (example: -m1,2,4,5,3)
-n#: Frame length: 0 = auto (default), max = 65536
-o#: Prediction order (default = 10), max = 1023
-p : Use long-term prediction
-r#: Random access (multiples of 0.1 sec), -1 = each frame, 0 = off (default)
-s#: Multi-channel correlation (#=1-65536, jointly code every # channels)
# must be a divisor of number of channels, otherwise -s is ignored
-t#: Two methods mode (Joint Stereo and Multi-channel correlation)
# must be a divisor of number of channels
-u#: Random access info location, 0 = frames (default), 1 = header, 2 = none
-z#: RLSLMS mode (default = 0: no RLSLMS mode, 1-quick, 2-medium 3-best )
Audio file support:
-R : Raw audio file (use -C, -W, -F and -M to specifiy format)
-S#: Sample type: 0 = integer (default), 1 = float
-C#: Number of Channels (default = 2)
-W#: Word length in bits per sample (default = 16)
-F#: Sampling frequency in Hz (default = 44100)
-M : 'MSByte first' byte order (otherwise 'LSByte first')
-H#: Header size in bytes (default = 0)
-T#: Trailer size in bytes (default = 0)
-I : Show info only, no (de)compression (add -x for compressed files)
Examples:
mp4alsRM16 -v sound.wav
mp4alsRM16 -n1024 -i -o20 sound.wav
mp4alsRM16 - sound.als < sound.wav
mp4alsRM16 -x sound.als
mp4alsRM16 -x sound.als - > sound.wav
mp4alsRM16 -I -x sound.als

I'm currently running a comparison between the freely available MPEG-4 ALS encoder and other popular lossless tools.
My preliminary table:
- WavPack 4.3 -fx5
- MPEG-4 {default}
(other formats/setting are coming)
Files are my 150 reference full tracks (=16 hours of music), classical music only.

The comparison is meaningless with encoding and decoding speed. But I didn't find any decoder for measuring speed, and I'm running the encoding task on a laptop which is handicaped by a slow HDD. The comparison is just "informative".

Scince this MPEG-4 lossless audio is standardized, does this mean that hardware support will be at least more abundant than the currently available players with any kind of lossless support?

Only if manufacturers are interested to implement lossless. And MPEG-4 ALS have to fight against other formats like:
- Apple Lossless
- WMA Lossless
- Sony's lossless
- FLAC
N.B. Monkey's normal has been add in the table.
Pretty cool. The big question now is who will adopt it... Let's hope Apple Lossless was just a stop-gap solution

Right, I don't see those companies abandoning their proprietary formats.
Yes, it uses BSAC (Bit-slice arithmetic coding). Correct me if I am wrong but isn't ALS hybrid codec that would be the purpose of BSAC? When I read the Research Paper on it that was the impression I got or am I missing something here? Is that something different.
If there is money to be made from it they sure as hell won't at the cost of patenting some other general coding technique used in data compression.

I tried a few encodings just to see the kind of compression & speed to expect. I put the encoder on verbose to get the speed and bitrate. I put comparison bitrates next to the "Average Rate" row, the comparisons are FLAC 1.1.2 at compression level -8.
My computer is fairly modern, it consists of:
Athlon 64 3500+ (2200MHz)
2GB PC3200 RAM (128 Bit Dual Channel)
Encoding From: 36GB SATA HDD
Encoding To : 250GB SATA HDD
I wanted to see how fast the encoder was with the "-7" switch, and at this point, it is very slow. Obviously this is an initial release and the specification is new, but man that's slow.

Interesting to see that the default settings are giving better compression than FLAC's highest setting. Seems the compression levels will be closer to Wavpack than FLAC. Very cool news, thanks for the info Guruboolez.

I wanted to see how fast the encoder was with the "-7" switch, and at this point, it is very slow. Obviously this is an initial release and the specification is new, but man that's slow.

=> MPEG-4 ALS has a better ratio than the current "very fast" and modern lossless encoders (flac and WavPack fast)
=> MPEG-4 ALS has a worse ratio than Monkey's -normal / -c2000
(results for classical music, but from my experience the difference between formats are extrapolable to other musical genres - with a higher bitrate...)
As a consequence, I expect from this first implementation and for the encoding side to perform as good as Monkey's -fast/-c1000 (fast encoding/average decoding) or WavPack -x4 (very slow encoding/really fast decoding).
The question now is: how fast/complex is the decoding side? As fast as Wavpack/flac? Slower than Monkey's?
- WavPack 4.3 -fx5
- flac 1.1.2 -8
- Monkey's Audio 3.99 -normal
- MPEG-4 ALS 2005.12.28 {defaut}
The setting I used for WavPack and flac are those giving the best compressing ratio with no sacrifice on the decompressing speed. For MAC, I used he default setting, which offers IMO the best compromise between ratio (strong), encoding speed (fast) and decoding speed (decent).

=> MPEG-4 ALS has a better ratio than the current "very fast" and modern lossless encoders (flac and WavPack fast)
=> MPEG-4 ALS has a worse ratio than Monkey's -normal / -c2000
(results for classical music, but from my experience the difference between formats are extrapolable to other musical genres - with a higher bitrate...)
As a consequence, I expect from this first implementation and for the encoding side to perform as good as Monkey's -fast/-c1000 (fast encoding/average decoding) or WavPack -x4 (very slow encoding/really fast decoding).
The question now is: how fast/complex is the decoding side? As fast as Wavpack/flac? Slower than Monkey's?
I did a small test on Where Is the Line by Björk, from the album Medúlla, ripped from a DVD-Audio (losslessly, search the forums). The audio is 24bit, 96kHz, 6 channels (5.1).
I have to say, the results are very, VERY impressive. I'm currently encoding the whole album to wavpack -hmx6 for my own use, so I'll do more testing later. But man, I can't wait for that codec to be supported by Free Software (I use linux most of the time).
Edit: added the filesize of the reference .wav file.

Does anybody know what patents are being used in MPEG-4 ALS and what the licensing terms are?
Just out of curiosity, has anyone done bit comparisons to prove total lossless-ness?
Wasn't LPAC the codec chosen a while ago for MPEG4 because of the lack of applicants?
QUOTE(dreamliner77 @ Dec 29 2005, 02:06 AM)

I just checked it out on a couple of files. The files I tested, coded then decoded all were bit accurate. I used the bit comparator in foobar2000. I checked the filesizes in windows and they were exact too.
Try this:
-b : Use BGMC codes for prediction residual (default: use Rice codes)
Edit: hmm, I guess -7 already does that. What's the effect of -p ? Try -z3, too.
-7 -p -z3 should give best compression ratio
-b : Use BGMC codes for prediction residual (default: use Rice codes)
Edit: hmm, I guess -7 already does that. What's the effect of -p ? Try -z3, too.
-7 -p -z3 should give best compression ratio
Thanks Guru for the comparisson 
QUOTE(HotshotGG @ Dec 29 2005, 01:17 AM)
Yes, it uses BSAC (Bit-slice arithmetic coding). Correct me if I am wrong but isn't ALS hybrid codec that would be the purpose of BSAC? When I read the Research Paper on it that was the impression I got or am I missing something here? Is that something different.
You are confusing it with SLS perhaps?

Ok, here is an encoding/decoding speed test. Album used is The Joshua Tree from U2, athlon64 (1.8GHz) cpu and linux. I have used 32-bit executables as there isn't a 64-bit object file for the adaptive prediction algorithm in the mpeg4als.zip.

The table is updated on the second post of this thread. Were just added:
- MAC 3.99 -fast
- WavPack 4.3 -x4
Summary:
• MPEG-4 default = 614,28 kbps
• flac -8 = 633,87
• WavPack -fx5 = 628,72
• WavPack -x4 = 618,27
• MAC -c1000 = 616,05
• MAC -c2000 = 603,20
=> MPEG-4 default has nearly the same compression ratio on this musical genre than WavPack -hx4 and Monkey's Audio -fast.
• Decoding speed (old Duron 800): x39 (WavPack) x20 (MAC)
• Encoding speed (old Duron 800): x1.1 (WavPack) x19 (MAC)
I can't evaluate speed on my laptop: results are varying too much from one encoding/decoding to another one.

That won't be known for quite a while. The MPEGLA does a call for patents, and tries to get everyone who has one that applies to MPEG4 ALS to agree on a common licensing agreement.

this is not a lossy framework as mp3 for example so i doubt that there will
be large improvements as the decoder has to be the same and tweaking
would break it. anyway lets see.

In terms of compression ratio, I would agree that significant improvement is unlikely. But in terms of speed, I would expect massive improvements.

heh, yeah I already built a linux binary. the readme doesn't say why it's missing though.
I don't see why all the fuss about encoding speed, it's the decode that matters. on my machine, default ALS decodes about twice as slow as default FLAC. it will be nice to see Hans' table updated for the big picture.

Yes, I agree: current speed is disappointing. Especially for higher than defaut compression level:
-z1 = decoding time = x0.9 on a laptop (AMD Athlon XP 2000+) and ratio is not impressive compared to extreme formats such as OptimFROG, LA or even MAC -c4000/5000 which are clearly less painful on the decoding side (and encoding too).
-7 = decoding time = x9 on the same computer. For such slow but acceptable (for PC) speed, ratios have nothing extraordinary.
For default setting, I was able to reach x60, whereas flac and WavPack -f could both reach x120.
Quick question, which app can play the als files?
A quick and dirty test. Timings are not accurate, I did a lot of work on my PC while encoding/decoding.
PIV 3.0 Ghz.

What are you trying to say here?
That the program says that it cann't work. -7 can not work with RLSLMS mode and -z3 set's RLSLMS mode.

You are wrong, it doesn't say it cannot work. -7 sets the parameters to the optimum, EXCEPT the ones for LTP, MCC and RLSLMS. (I guess because the effect on speed). But you can still manually set those to the optimum values.
I already showed you can, and BoraBora's result shows that they have effect.

Sorry.
Sorry.

-7 = decoding time = x9 on the same computer.
Interesting, your decoding of a -7 file is faster than mine even though I have a faster cpu. I tried some other files and it looks like decoding speed is very variable. I made a graph showing the variability, decoded is whole album (507MB). However, decoding speed for a file encoded with default settings is pretty stable.

How slow and how compact is -7 -p -z3 ?
Does it beat the most insane OptimFROG lines?
Does it beat the most insane OptimFROG lines?
It may be.
For some reason, I can't make work "-7 -p -z3". Encoding stops after a couple of seconds. Weird. 
I tried "-s2" and "-s2 -p", though :
CODE
186661407 46,36% "-p -s2"
186886405 46,42% "-s2"
186900432 46,42% "-p"
187611042 46,60% default

I would expect results from -7 -z3 to be better than all others you tried, if you can't get -7 -p -z3 to work.

No, it stops and the prompt comes back. I have no error message, though I'm in verbose mode. Nothing. It starts then seems to change its mind and stops. Too much work, maybe?
I'll try again on a small sample.Edit : well, same thing on a single short track, with or without -v. I don't understand.
yah that's what happen's to me to.
For me:
-7 switch does not work with -z3 switch. Or wise versa
-z3 alone works.
If somebody isn't lazy enought to find, what switches -7 sets or resets, then he will be able to find the specific switch that doesn't work with -z3...
EDIT: BTW, for me encoding with -7 -z3 is ended imidiately, not after some seconds...
