AC3->MP3 without intermediate files?

[CyberDemonII]

Hello matter,

I am not sure i will 'release' ac3tomp3 in that way.

I did need it for my dvd2avi_gui program :

http://www.geocities.com/compressavi/dvd2avi_gui/dvd2avi_gui_1.08beta16.zip

Let me think what your opinion is about this one !

grtz,cd2

[DanniDin]

Just So AC3toMP3.exe Won't Be Lonely and Until it will Get its Own Screen in the GUI Here is Azid/LameGUI v0.4 beta1 (http://worldzone.net/computers/dannidin/AzidLameGUIv0.4b1.zip)

Danni.

@matter
I dont think anyone cares what size the app is, if its 5MB or 200K. Who cares? I'm pretty sure most of us are using a hard disk of more than 240MB now a days :-) If you want to concentrate on something then focus on the speed and compatability.

well, i guess you saw that the new version is amazingly fast, and btw - it all fits on one floppy disk.
as for compatability, well, only w$ndows...

@DanniDin
the new file-configuration screen is beautiful, grEaaaaat stuff !
please add a checkbox regarding WaveBooster, in case some1 wishes to disable it. (current version always set switches for WaveBooster).

Thanks DSPguru :)

I'll Have to Add a Special GUI "Screen" for Your Program that will Have More Options.

v0.61 (http://rilanparty.com/vbb/attachment.php?s=&attachmentid=107) now supports all presets :
phone, voice, fm, tape, hifi, cd, studio

also switches parser is more flexible now.
this command will work for example :
AC3toMP3 -azid( -g max ) [output.mp3] -lame( --r3mix ) -bbdmux( 0x86 ) [input.vob] -boost( /b=4 )

(that's for all of you guys who asked for flexability ;))

[FLivanova]

I just tried out AC3toMP3 and it looks very useful. Thanks for taking the time to release it. A few questions though:

Are all LAME options supported? I am a hardcore lame user and would like to use some specialized settings from time to time.

It would also be nice if you could add a setting to add a certain amount of gain + the max gain setting from azid. Or is it already possible to normalize to more than 1?

Something like -g max+3db would work ;)

I find that the max sound level in the movie is usualy a door banging or some other loud noise that can withstand a bit of clipping. If I add about 3db to the gain the whole movie sounds better and you don't notice the clipping in the loud noises. It usualy happens only a few times anyway.

Thanks again for your interests in making a great util.

[b0b0b0b]

Do I have to encode each vob to mp3 separately?

Also, there's no way to join mp3's seamlessly, is there?

[dvdyke]

Good question. Does it rip the ac3 stream to mp3 from the VOB's 1 at a time or goes through them all to create one large MP3 from each stream? Time for a readme for AC3toMP3 don't you think? :)

on the zip, look for lame sw.html , there you can find all LAME's supported switches.

about normalizing,
setting a gain, bigger then max-gain would cause overflows in azid.
if you think the soundtrack should be increased by 3db over max gain, try using this combination :
AC3toMP3 -azid( -g max ) -boost( /b=3db /l=0.99 )

@ACClarke
if you wish to create a virtualdub-compatible output, use this switch :
AC3toMP3 [input.ac3] [output.wav] -core( -wavmp3 )

@b0b0b0b

Also, there's no way to join mp3's seamlessly, is there?

joining mp3 is a simple binary append. (copy /b)
DanniDin, please add a checkbox to your GUI : "Join AC3toMP3's products!" (and implement it by yourself.. ;))



@dvdyke

only one stream is extracted each time. that's what bbdmux do.
btw,
i am now optimizing BB's code for a faster version of bbdmux.dll. i already gained about 4% speed improvement comparing to the original version.
i might add a multi-substream support, but it's not on my task-list at the moment.
anyway, how many ppl would be interested in this feature ?

Time for a readme for AC3toMP3 don't you think?
i'm counting on Doom9 here, ask him to update his AC3toMP3 Guide (http://www.doom9.org/ac3tomp3.htm) ;).
and for more comfortablity, you can always use DanniDin's beautiful GUI v0.4b2 (http://dspguru.tripod.com/GUI.zip) :cool:

info about AC3toMP3 v0.62 :
- will include the optimized bbdmux.dll
- will include a new & automatic dynamic-compressor (that will automaticly calculate how many dBs should be "added" to max gain.)

[Doom9]

joining mp3s? hmm.. that is a major pain in the ass and very error prone. when I voted for direct vob -> mp3 support I was kind of thinking about the whole ac3 being demuxed.. then being encoded as a whole, not file by file.

[pacohaas]

I agree with doom, a list file as input is probably the easiest solution.

[DSPguru]

VBR would be problematic. true.

ok... so i can add an option to recieve a list with all VOB files, but what about the substreams ? and what about the max-gain routine ? could each vob have a different gain ?

to make things easier, i were thinking about the following plain-text file format :
[filename1.vob]
substream1
[filename2.vob]
substream2
:
[filenameN.vob]
substreamN

another idea is to have a plain-text like this :
[filename1.vob] -bbdmux( substream1 ) -azid( gain2 )
[filename2.vob] -bbdmux( substream2 ) -azid( gain2 )
:
[filenameN.vob] -bbdmux( substreamN ) -azid( gainN )


i guess that DanniDin's GUI will create this list-file automaticly for all the drag-n-droppers ;)

@pacohaas
How come AC3toMP3 hadn't got to your Fairuse homepage ? still insists to keep it as a secret until i release a SSRC-supported release ?

[pacohaas]

sorry it hasn't made it up yet, you'll notice also that HeadAC3he hasn't made it yet either and I've been using that method for about 3 weeks. I intend to revamp the audio section when I get a chance and it will have 3 choices:
1. the old method(batch file only)
2. AC3toMP3 (probably with a batch file example)
3. HeadAC3he+wav-->mp3 w/batch file

I just need to get off my lazy butt and get to it.

...on that note(laziness) has anyone tried using 24-bit output from azid in AC3toMP3? That would mean that the max gain is calculated with more bits in mind so it's theoretically more accurate.

[DSPguru]

AC3toMP3 max-gain calculation, and in fact, most of the process, is implemented on a floating-point basis.
it's already as accurate as you can get.

[FLivanova]

Thanks, missed it. Are all the --r3mix switches used internally in the lame dll? I guess so.

If you have time could you please add the --lowpass switch as well? Also, I see the -h or -q? settings aren't supported. Do you use -h by default?


about normalizing,
setting a gain, bigger then max-gain would cause overflows in azid.


yep


if you think the soundtrack should be increased by 3db over max gain, try using this combination :
AC3toMP3 -azid( -g max ) -boost( /b=3db /l=0.99 )

That looks like it will do the job. Thanks :D

[dvdyke]

The ability to convert the substream from every VOB to one MP3 file without having to join MP3's etc is a must. Surprised this was not implement as a default. I assumed it would do that and so did Doom9 by the looks of things ;)

[LigH]

F$%&ing mail notification - I'm still left behind... :mad:

Oh hell, you guys are doing a great job: DSPguru is changing his former one-step converter into what germans would call an "egg-laying wool-milk-pig" (sorry, sounds like some "english for runaways" :p); AC3toMP3 is truely becoming an all-in-one tool. :eek: The worst problem only is: More parameters, even more parameters... :(

@DSPguru: Nice to see that you enabled an "#db" parameter mode for the boosting function. Shall I add that to my WaveBooster? (Does anyone still *need* my stand-alone WaveBooster??? :D No, I don't mind!)

[b0b0b0b]

I have a quick suggestion about the vob2mp3 part.

How about it does what dvd2avi does and if you tell it the first vob, it looks for all subsequent consecutively numbered vobs (by default). I think that's the 99% of the time scenario anyway.

Also, is there any way for vob2mp3 to tell us the ac3 delay much like dvd2avi does?

Thanks for a cool utility!

[DSPguru]

@FLivanova
for now, i believe AC3toMP3 supports all switches accesible by the dll version of LAME.

@dvdyke
hehehe...
it's nice to hear you assumed it would do that, but in this case : it=me, and i don't have all the time in world working on this voluntary project ;).
whenever i have spare time - i add features.
but must admit, i'm getting tired lately...

dear LigH
the #dB support for WaveBooster is a by-product of the switches-parser i wrote.
in fact, if you'd write the switch -V0db it would act the same as writing -V 1. ;)

b0b0b0b
i never used DVD2AVI, so i can't imitate it.
anyway, do me a favor guys, let the GUI create the batch/list file.
at least for now.

i were thinking of a way to put some order into the switches syntax :
AC3toMP3 -core( -input [?.vob] -output [?.mp3] -substream 0x8?) -lame( ... ) -azid( ... ) -boost( ... ).

basicly, the idea is to remove the -bbdmux() section and to add input&output file specifiers. (instead of "assuming" that a string ends with ".mp3" is the output file, etc'..).

that would probably be the syntax of the upcoming version.

[LigH]

Checking for an A/V delay shall be not the worst problem: All you need to do is completely analysing the stream structure. It is a quite heavy work, but I've done this once, while trying to write a video bitrate stats collecting tool. You really need to know the structure of a VOB sector and all the MPEG system stream blocks.

I don't really remember (but it's very probable) if there is a timecode for the start of the audio stream available in the VOB sector headers; I think there shall be an offset in periods of the decoder frequency (27 MHz or some like that?) for each audio block; at least each video GOP has a timeode, and from there it must be possible to calculate at least at which video frame the audio starts - finally, a consumer DVD player must be able to do the same...

[echan09]

hi:

I use the following options for converting ac3 to mp3 using ac3tomp3:

ac3tomp3 input output -azid( -c normal -g max ) -lame( --abr -b 128 -m j )


I'm having problems with sound volume going soft and loud where it's not supposed to. The original AC3 file doesn't have this problem. Any suggestions.

Thanks

[DSPguru]

try not to use dynamic compression :
AC3toMP3 input output -azid( -g max ) -lame( --abr -b 128 -m j )

[Beave]

Thank you very much for that wonderfull Program!

Some questions:
How can I make a mono ~45kbit mp3? I want this for the Commantary stream. -lowpass10 and -resample32 would be nice for that. I used to have this command:
-azid( -oc -d1/0 -cnormal -smono -g max ) -lame( -mm --voice -v --vbr-mtrh -V 9 --lowpass 10 --resample 32 --athtype 3 )
Doesn't work with ac3tomp3, unfortunatly.
Any commands on that?

What is the best OneCd lame-switch nowadays with AC3toMP3? How about -V7 -mj -h --vbr-mtrh --athtype 3 --lowpass 17? Would --lowpass work with any workaround?

Is it possible to use a preset and then change values, like --r3mix -V9 -b32 -lowpass16 ...? This doesn't seem to work here.

How come the Auto-Boost value in the GUI is set to 6? The sound was extremely distorted. I use /b=2 /l=0.95 rightnow.

Best regards

[Huge]

Hi,

I'm seeing some odd things with ac3tomp3. It may just be a co-incedence but my last three VBR encodes have come out with a bitrate of exactly 160. If I use the old ac3-wav-mp3 method on the same files I get lower bitrates of around 112 which is what I'd expect with the settings I'm using.

Here's my current .bat file settings (created using danni's gui).

"C:\DVD\Tools\ac3tomp3\AC3toMP3.exe" %1.ac3 %1.mp3 -azid( -z1 -b1 -c normal -g max -L -3db ) -lame( -m j -v --vbr-mtrh -V 4 -b 80 -B 256 --athtype 3 --nspsytune )

Any clues?

BTW: This program is sooooo fast compared to the old way's...

[Derian]

sorry for my bad english.

i have a ac3 file with dolby (3/2 channels) using DVD2AVI.
if i use the AC3toMP3 program, will the mp3 file keep 3/2 channels (Dolby Digital)?? and in the future??

Again sorry for my bad english, i hope that this forum accept foreigns ;).

[Beave]

if i use the AC3toMP3 program, will the mp3 file keep 3/2 channels (Dolby Digital)??
No, the mp3 will be Dolby surround at the most. So 2/1 is possible. If you want to keep the 3/2 simply take the generated .ac3 file an mux it with the video. There are some good guides on that on the doom9 site.

I wonder what the "Natives" of this forum would be? Is doom9 or/and each moderator the inhabitant of this place? What is the're native language? Hmm, too many thoughts I guess...
So , don't feel sorry.

[LigH]

According to the "ifrance" mail domain, doom9 may be French; many other members are Germans for sure; I know one from New Zealand... We all are newbies, with more or less experience in one or other areas.

[DSPguru]

@Beave
thank you for your kind words.
for now, AC3toMP3 doesn't support mono mp3 outputs, and neither do supports --lowpass or --athtype.
look here (http://DSPguru.tripod.com) for all supported Lame's switches.

about Booster, default boost=5, but you can set any value you find enjoyable.

@Huge
i've rechecked the VBR mode, and it's working good, varying all the time.
tell me, when the program print all settings, does it look like it "understood" all your switches ?



BTW: This program is sooooo fast compared to the old way's...

that's the idea ;).

[Huge]

Mr DSPGuru Sir :D

I've just a AC3 file through Danni's AC3-WAV-MP3 batch process and then used AC3toMP3 with the same switches. Danni's batch version gives me a bitrate of 140 while AC3toMP3 gives me 159.

[Huge]

I missed your question. Yes, AC3toMP3 looks like it picks up all the parameters OK.

One additional thing... there's a bug in the time display output. I've seen it jump around a bit and sometimes once it goes over the hour mark, the hour counter resets to zero or a - char.

Does anyone have a good VBR command line for 1CD rips?

[Beave]

Do you know if the --r3mix has all the commands "in it", even if --lowpass and --athtype is not supported bei the lame.dll?

Hopefully there will be a oneCD and twoCD Switch one day like --oneCD...

[DSPguru]

Originally posted by Beave

--r3mix include it all, yes :)

Hopefully there will be a oneCD and twoCD Switch one day like --oneCD...

maybe it's time to start a discussion about what should --twocd & --onecd represent.

[pacohaas]

here's my 2 cents:

1-CD (going for minimum size)
--nspsytune -V9 -mj -h --athtype 3 -Z -X0

2-CD (very high quality)
--nspsytune -V1 -mj -h --athtype 3 --ns-sfb21 2 -Z -X0

It's my feeling that the default lowpass set by the -V value is good. I know athtype isn't supported by AC3toMP3, but if the default athtype is 3 or 4 then I think it'd be ok to leave those off too. I can't recall what it is since it's been changed a few times, but if someone wants to check it out either at r3mix.net or in the source code, that would be great.

Again, just my 2 cents.

[Huge]

Hmmm, smallest file size is not what we should be after for 1CD's. Pacohaas, I know you're a FairUse user too and I'm guessing these aren't the settings you use for 1CD's. In fact we should try and emulate what FairUse is all about - *maximum quality* in the smallest file size.

My take at the moment would be to make 1CD's VBR and use -V4 but then I'm no expert on these things. -V9 seems a little cut-throat to me.

How about having --1CDVBR, --1CD settings?

[dvdyke]

Yes. I am still waiting to actually use this util but am waiting for something like a decent GUI or a batch file I can drop the 1st VOB file onto on the desktop and it will pull the 3/2 stream from all the VOB's in sequence and go to either 1 or 2 CD Lame MP3 with the optimum quality. Too much confusion about what command lines work best at present and no multi VOB stream pulling yet either. I'm too lazy to do it at the command line each time :)

[pacohaas]

Pacohaas, I know you're a FairUse user too and I'm guessing these aren't the settings you use for 1CD's.Yeah, I go back and forth as to what I think a --oneCD preset should be. It comes down to personal preference. A year ago -V9 sounded pretty bad, but now with npsytune and all the other improvements, it sounds ok. Add that to the fact that you're not just sitting there listening to the sound, but involved in the whole movie experience and I think many people won't notice a difference between a 95kbps sound track and a 145kbps sound track. As you have suspect, I don't just use these settings blindly, but instead vary the -V value depending on the movie length and compressability of the actual movie. I have, however, used -V9 on many of my rips and to tell the truth, I can't tell the difference between those and ones that I've used -V3 on when watching a movie. Granted I'm using speakers that are embedded in my monitor, so again, personal preference/equipment has to be taken into account. Presets are a tough thing to agree on. Maybe DSPGuru could work on an adjustable preset like some of dibrom's ABR presets. here's what I'm thinking:

--divx N

where N is the -V value, for instance:

--divx 6 stands for:
--nspsytune -V6 -mj -h --athtype 4 --ns-sfb21 2 -Z -X0

Here we've got 3 things that would be adjusted based on N(the ATH curve, lame's internal lowpass, and consequently --ns-sfb21 2 because it only affects frequencies above 16kHz) Ok, well I'm going to see if I can find some info on what ATH method LAME currently defaults to.

Aha! But Doom9 also speeks Swedish. Anyone up for just asking him? I would be really embarased to ask someone's race, it is rather odd to do that in my culture. (I hope Doom9 does not read this).

[Beave]

Since ac3tomp3 does not support all these fancy lame-settings what would be the best value there? Without lowpass and athtype and all those others what would be good for one CD? I mean for 2 CD we can take --r3mix.

I agree -V9 isn't that bad in movies, especially if you use lowpass like 16kHz. Usually the high frequencies reveal the compression first and if you don't compare it the original you won't notice the lowpass. The sound in movies isn't that clean either so artifacts will only show in heavy music parts. A setting of -V9 results often between 100 and 112kbit avg, which isn't that low either.

When I have heavy action movies with great sound I go for 2CDs with original ac3 sound.

[_TAG_]

just my 2 cents on lame options 4 encoding movies... just a suggestion (got switches from r3mix site, of course, with some adaptations)
note: i make 2 cds movies with 2 audio tracks, that's why my presents are somewhat space saving :p

movie small:
obviously for 1 cd movies which need the smallest audio (like animes, not Princess Mononoke)
--ns-sfb21 2 -Z -X0 -m j -v --vbr-mtrh -V 9 -b 32 -B 160 --lowpass 16 --athtype 3 --nspsytune

movie:
for 1 cd with decent sound or 2 cds which need a lot of video data (like batman)
--ns-sfb21 2 -Z -X0 -m j -v --vbr-mtrh -V 6 -b 32 -B 192 --lowpass 17.5 --athtype 3 --nspsytune

movie hi:
for 2 cds movies with a good sound/soundtrack
--ns-sfb21 2 -Z -X0 -m j -v --vbr-mtrh -V 4 -b 32 -B 192 --lowpass 17.5 --athtype 3 --nspsytune

sometimes i make the english soundtrack with <movie hi> and the italian one with <movie>, to save something on the audio track i don't usually listen to.

btw, shouldn't we switch lame settings discussion in a new thread?

[DSPguru]

the idea was to agree on presets supported by the lame_enc.dll so i can add "-onecd" & "-twocd" presets to AC3toMP3.

it seems we lost focus :rolleyes:

please get back to the original discussion :
what should "-onecd" & "-twocd" represent in AC3toMP3 ?

[_TAG_]

didn't lose focus...

but maybe we could have 2 other presets:
-doubletwocd
for dual audio tracks on 2 cds (like <movie>), and
-smallonecd
for movies on 1 cd which need more video bitrate (like <movie small>)

imho --r3mix (or --dm-preset normal) is a good candidate for --twocd.

[pacohaas]

@TAG, specifying -B will only lower the quality and save maybe 1% of the filesize in movie soundtracks. It looks like you are going for a fast encode with the mrth and no -h(-q2). Neither of these flags are supported yet by AC3toMP3

@DSPGuru, how hard would it be to support -q and --npsytune? I assume -q is simple and npsytune might be next to impossible, but I just want to make sure.

also, i had a look at the source code and 0 is the default -X value and --athtype 3 is the default ATH for VBR though 1 is the default for ABR/CBR.

didn't specify the -q2 cause that's what i get using RazorLame.

the mtrh is what r3mix uses, and i trust him (the --dm-preset doesn't use mtrh, so maybe it's the way to go, but i get pretty good results nonetheless).

as for the -B, i'm currently encoding Ronin audio, and i'll post the filesizes with -B192 and -B320, to see the difference...

btw, if ac3tomp3 does support --r3mix, it means that internally it uses the --npsytune, so it shouldn't be that hard to add it as a switch. (if i'm wrong please report me to the nearest sanitarium prior to flame killing) :D

for the last time : NO !!!
AC3toMP3 configures lame thru a BE_CONFIG structure, that DOES NOT have fields related to athtype & others. regarding psytune, it is written :
DWORD dwPsyModel; // FUTURE USE, SET TO 0

probably after lame 3.90 source code will be released, i could check for any changes.

the -r3mix is a PRESET. when i tell the dll : nPreset=LQP_R3MIX_QUALITY, the dll starts to fill all parameters internally. but still, i don't have access to this internal parameters.

i can only do two things :
1. to post about this shit to lame developers (i already did (http://66.96.216.160/cgi-bin/YaBB.pl?board=c&action=display&num=1006889666))
2. to release my own version of lame_enc.dll that support everything (but that means - going back to version 3.89 :()

so please, don't give me hard time on this, i already did all i can do.

[DSPguru]

AC3toMP3 v0.7a (http://rilanparty.com/vbb/attachment.php?s=&attachmentid=114) now supports list-file input.
more in the package :
- an example of list file.
- latest lame_enc.dll.
- a new & optimized release of bbdmux.dll

pay attention to the new syntax.
for a kick-start, just run the exe.

[damjang]

Hi DSPGuru! Thank you for your job...

I try AC3toMP3 0.61 (I deal with an 3h45min ac3 - 2dvd all in one rip) I see the time going positive and negative all the time: let I explain: first have e.g. 35 min decreasing and when arrive at 0 go to -35 decreasing to 0 and then 4-5 times the same. What this mean?

Thanks
DamjanG


PS: The handlig of mono files will be usable too...

[DSPguru]

Hi damjang,
please download AC3toMP3 v0.7a (http://rilanparty.com/vbb/attachment.php?s=&attachmentid=114) and see if this bug still occurs.
anyway, as long the bug relates only to the interface and not to engine itself. i'm relaxed :p.

as for mono MP3,
i'll think about it..

[Huge]

Hi Mr Guru Sir :D

trying to figure out these new switches in 0.7a and failing miserably. I don't get any syntax errors (I think I should be getting some errors) but the program starts and just displays the help screen.

I've even copied and pasted your examples and they do the same.

edit - my mistake. I wasn't including the -output parameter as looking at the examples in the .lst files there are some that don't have it. I assumed it just added a .mp3 extension to the input file.

If it'll Help You then I'll Release Azid/Lame GUI v0.4 beta 3 in a Few Hours...
