MPEG Audio Layer-3 mpg123 Decode Filter (by Mukai Tetsuji [Warlock])

[Chibi Jasmin]

Found this in tsunami filter pack 3.9.3. it's a Direct Show MP3-decoder (L3mpg123.ax)...is it any good? Where can I find some info about it (any homepage for it)? Version info is 1.0.0.0....is there any newer version?

Any information appreciated!

[DSPguru]

according to David Robinson's decoders test, mpg123 is a very good (the best ?) mpa decoder.
lame,cdex,mp3directcut and lots of others are using mpglib.dll that is based on mpg123 for decoding purposes.

[Rodger]

What codec are you guys using for the audio in DivX5?

Still Radium V1.2 (org. Fraunhofer??).
Otherwise is there anything new?

I searched on the web for a new mp3-codec but didn`t find anyhing.

Thanx...does the DS-Filter have a homepage or something...?

I think I'd rather see a DirectShow implementation of MAD.

[Nic]

Word has it....

That the elecard MP3 Decoder uses the MAD Library (!?) The thread about it was once in this forum somewhere..

(Me & David Robinson (2BDecided) were at the same Uni at the same time...I still cant believe we never met :) )

[Chibi Jasmin]

What are you two talking about? I don't get it...I been searching for some info on the mpg123-Direct Show Filter. A homepage or something...

Mad? Elecard? Are they other decoders?

Or in other words...what DirectShow-Filter would you suggest for mp3-decoding? Is the mpg123 good or not? Any better ones?

[Nic]

Poor Jasmin..... :) (j/k)

The MAD decoder can be found at www.mars.org/home/rob/proj/mpeg/
I originally came across it as a WinAMP plugin...It is a very good MP3 Library, some say the best decoder.

mpg123 is a very good decoding library & I have some familiarity with it. It is highly recommended. But I know nothing about the DShow implementation.

The MAD decoder is very accurate & using some sort of dithering to improve the sound (I cant remember how off the top of my head :) ). Elecard produce many DShow filters for download. The company can be found at www.elecard.com (they have been bought by moonlight). It is believed that there freeware MP3 DShow filter uses the MAD library.

Hope some of that makes sense & helps.

Cheers,

[Chibi Jasmin]

Yeah, thanx...will check these out...

UPDATE: Didn't find any MP3-Decoding Filter on the elecard-page...well, as you say mpg123 is good, maybe I can keep the MPG123-DS-Filter... I am still curious, where it comes from and would like to find some info about it... :-)

[Sven Bent]

i wnat this tooo
where cna i get these mp3 playback filters

they most be better then this OLD fraunhoffer DSfilter I'm using

its rather hidden. but i founbd it
its under downlaods and its name is somthin with dakota decoding

its contains mpeg 1layer 2 &3
mpeg 2 layer 3 and ac3 decoding

Well, the mpg123 one I been talking about is in Tsunami Filter Pack V3.9.3! Get it here: http://www.dvbpool.de/tsunami/uebersicht.html

Well, we now just have to find out, which is better, mpg123 or the elecard/mad [is it mad? Nic said it is BELIEVED to be mad) one :-)

For me the choice is simple
If one produkt is fokused on one thin it must be better then something trying to gab to wide.

Look at icq it only got worse by bloating it up with sh*t :-)

Did I get you right, you are going to use the mpg123-filter, because it only concentrates on mp3 and not on ac3 and mp3 as the elecard-filter? Or do you mean mpg123 development concentrates on only one thing and elecard/moonlight concentrate on many things?

We need some more info on both of the filters. Which version of what decoding library they really use (okay, mpg123 seems to be mpg123-library), at least...then some knowledged people could say some wise words about the quality...both filters work without hassle, that's all I can say for now...but the fraunhofer worked, too...

[Nic]

To be honest if you cant hear the difference don't worry about it.

You could check out David Robinson's site:
http://privatewww.essex.ac.uk/~djmrob/papers.html#mp3

especially:
http://privatewww.essex.ac.uk/~djmrob/mp3decoders/decoders_winampmpg123.html

But I cant see why this is bothering you so much.....

-Nic

[Chibi Jasmin]

Thanx for the links, it's not bothering me very much, I am just interested and looking around...

There seems to be no documents on the web about the mpg123-DSF implementation...

[Nic]

Dont worry about the DSF implementationof mpg123, its only the actual mpg123 library that concerns the issue of quality.

Warlock's page is down, & was on a japanese server so, there is probably little English text on the matter...

Well, I'll try not worrying too much, but hopefully it is a good version of the library used in the DSF :D Thanx!

Since the file is http://www.moonlight.co.il/download/lame_dshow.zip

I assume it's based on LAME and so on a modified version of mpglib...

[Nic]

That Lame DShow is an encoder not a decoder isnt it?

(The odio dekota one does appear to link to the MAD lib, So Im pretty sure its based on the MAD MPEG Decoder)

-Nic

Yeah, it an encoder...

and okay, let's assume one is mpg123-lib (seems to be clear) and the odio dekoda is mad lib...which one to choose for mp3? They're probably both okay...

[Nic]

This could be considered trolling Jasmin..... Please stop asking questions over & over again, on this minor issue.

I conclude you don't have anything to add to this "minor issue".

[DSPguru]

i've noticed Jasmin is a very rigorousic babe :). she won't let go until you supply precise answers :
"what's the difference between mpg123 to mpg123-dsf (to mad)","what's the difference between aac 2 to 4", etc'...

i respect her :).


@Nic,
how could you study in the same university with 2bdecided without ever meeting him :o ?

[Nic]

Your only saying that because she's female ;)

I respect her too, but I'd much prefer to hear: "Ive tried both & I can definitely hear better quality with the MAD Decoder", etc, etc. Rather than asking the same questions over & over again. I dont mind helping people, but guiding them every step of the way is irritating, especially without them actually do anything to progress the discussion. Sorry to sound so harsh,

OT:
I know, whats worse is me & David lived in the same village(!!!) :)There was only a population of a couple of hundred (if that). Small World. :)

(BeSweet is using mpglib.dll ;))

Rather than asking the same questions over & over again.hehehe, so why are you replying ? you can ignore the thread, you know :rolleyes:.
i once remeber reading a very funny thread, it went something like :
first post by some user : "how do i a b c d e f g...???"
reply post by another user : "i don't know".

that's another example of where users should NOT reply :).

Nic, I didn't wanna annoy you...sorry, if I did...maybe I should have stated that I would probably not be able to hear these small differences, because a) I am not trained b) I don't have expensive audio equipment.

I just was interested in what exists and what it's based on...and of course, what the experts have to say about it...for every-day use it's not that important, which mp3-decoder I use, I admit that...sorry for asking too much...

[Nic]

No, Im sorry, its the stress of my job getting to me today. Too darn busy...... :) I hope I helped some.

Seriously though :), If you really wanted to find a more precise answer, posting the question at hydrogenaudio.org probably would get a better answer. People like ff123,2BDecided,etc spend much time & effort into comparing audio decoding/encoding.

(& Ill go check out the new spiderman film to see if I can appreciate this Kirsten Dunst girl ;) )

Yup, I should have stopped replying you're right :)

Yeah, sure, you helped...I'll take it over to hydrogenaudio later, if I find the time...

Have fun watching Spiderman...not sure, if it's your kind of movie, it's not mine, but Kirsten is for sure a reason to watch.

is was a kind of joke. off cause i would use theone that some propper test woudl show for best if the arguments where right.

however i rather like havin one filter for mp3 an another for ac etc etc

make it more easy to uninstall and upgrade for newer/better (other) versions

[Chibi Jasmin]

I had the elecard one registered and it took over only mp3, ac3 was still decoded by intervideo audio any hassle...

I'd say which library you use depends alot upon personal preference, however, definitely, at minimum, get the MAD Winamp input plugin to replace the crappy Nitrane Decoder that comes with Winamp. MAD is highly accurate, and as mentioned before, its dither works wonder with low bitrates.

The default mp3-decoder in Winamp claims to be from fraunhofer...

The default mp3 decoder that comes with Winamp 2.x+ (in_mp3.dll) is Nitrane. A fast decoder written mostly in ASM by the Winamp team, quality is not that good however. :(

Not Windows Media Player... WINAMP. (i.e. winamp.exe)

[Chibi Jasmin]

Okay, I read it again..it says technology licensed by Fraunhofer :-) Sorry...

[DSPguru]

btw, i recall that Warlock have compiled a library he called libmad out of MAD. since he made a dsf version of mpg123, it is possible that later on he had made a dsf out of MAD.

[Chibi Jasmin]

But that doesn't have anything to do with the moonlight/elecard dsf that's also supposed to use mad-lib?

http://privatewww.essex.ac.uk/~djmrob/mp3decoders/decoders_winamp.html

With version 2.666, Nullsoft finally dumped the buggy Nitrane decoder, and switched to a decoder apparently based on code from the inventors of mp3 (FhG). Winamp hasn't had a decent mp3 decoder since version 2.22, when the company briefly switched from Nitrane to FhG code

[int 21h]

OOps, I must have missed that. When I install Winamp on a new system, I always just delete in_mp3.dll without even looking at it anymore, and replace it with in_mad.dll (<-- MAD rules).

There are two filters from Elecard, both available for free download from http://www.elecard.com/download/
Odio Dekoda - Audio Mpeg Layer 2/3/AC3 decoder
MPEG Layer III Audio Encoder - Audio Mpeg Layer 3 Encoder based on Lame source code

[Kyo]

@Chibi-Moon (you like Sm?)

Personally, and at least for winamp, I tried both of them(long time ago...) and I think (hear :D) that MAD is a bit better, so for me (and my ears) MAD is my choose.
