Audio (AC3/DTS/MPEG/LPCM) and Video (MPEG2) plugins - Page 3

@Nic,

Here's a bunch of lpcm streams:

I think the trouble is that you are using a WAV LPCM file rather than a raw LPCM stream from a DVD.

I should really compensate for that in the AviSynth plugin, but it's a bit of a hassle.....

I'll see what I can do though.

Ok, download NicAudio from nic.dnsalias.com again ( http://nic.dnsalias.com/NicAudio.zip (look in the readme to make sure you don't have a cached version))

This now supports LPCM Wav files with 2 channel audio (but no more than two channels, don't have the time to add support in for the rest right now)

-Nic

iNFO-DVD · 4th July 2005, 15:25

Wow that was quick. Just gonna test it now.

Excellent

I only use it for the preview in my program so it wouldn't matter to me if it was whatever bitrate or channels as long as I could hear it, just re-updated with the v1.1 dll and everything is great, phew, glad you was online and thanks again.

Cheers!

@ Nic:

Does it also support 20 bit LPCM? I don't have it - I just solved the interleaved format in "Twen"...

LigH · 1st September 2005, 17:10

And another idea (I hope, you are still out there somewhere, Nic?):

It would be great if you could support loading custom downmix matrices and gain settings as they can be exported out of AC3Filter.

Nic · 1st September 2005, 22:56

Hey LigH. Yup, still alive & kicking....inbetween trying to get my wavelet codec to work, making my AVI->EXE program, actually getting around to deciding what i'm going to do with QuEnc, oh and spraining my ankle yesterday playing football (my right foot is now twice the size of the other)...i'm quite busy and active.

The main problem is that I can't visit this forum easily anymore. Something's changed, and i've not had time to work out the problem, but the proxy at work doesn't like, nor does my home connection (using IE at least, firefox normally works fine)

Anyway, I digress.

I don't have many LPCM streams and when I do download LPCM samples, without having more than two speakers and a need to use them, I haven't had the patience to work out what's needed. One day I'll find the time. On the plus side the source code is very easy to read, understand and change so maybe someone else can do it.

The only real difficulty is the way the samples are interleaved. I don't have that info (without looking through lots of source), but I know folks like MPUCoder, DVD Lightning, neuron2, etc have more info on it.

http://www.ligh.de/software/Twen!.rar

contains a document which shall explain how the 20-bit interleaving in stereo streams works, and how you could change it to 16 or 24 bit samples acceptable in WAV files.

MPUCoder instead will know more about any possible channel mode for 20 bit LPCM. I read some details about the MuxMan development (katjarella always informed me about interresting news).

Cool

That will help a lot. I may try and do it tomorrow if I get chance. Or at least give it a shot.

hi,nic

I can not visit your homepage.
Will you please send your software to me? I mean all your program.So I can provide
download for my friends

meilinxiaoxue AT GMAIL DOT COM

thx!

hi Wilbert
thank you!

Nic's plugin works great, only thing missing now is AVS-input for BeSweet. Together with dimzon's 6-ch he-aac winamp plugin we'd have a perfect hassle-free (= no 7-8 gig temp space for intermediate wav files) freeware DTS => HE-AAC solution.

i miss this function soooo much.....

Mug Funky · 6th January 2006, 05:26

holy thread ressurection batman!

it just occured to me to post this (not really bug) problem with nicac3source, and most probably the filmshrink plugins it came from.

basically, any ac3 with embedded timecode will be out of sync by an unpredictable amount (i don't think it's just the difference between 00:00:00:00 and the start time of the tape, or there'd usually be 1 or 10 hours of silence). now this doesn't matter with DVDs (the compile process strips out ac3 timecode), but it can be a problem with an ac3 file produced by either soft encode or a Spruce card (and probably several other hardware encoders).

of course, i can easily run a separate little app to strip the TC out, but there'd be no fun in that

. it also might save a lot of fuss with other people if they come across the same kind of files.

LigH · 6th January 2006, 14:02

Not absolutely related, but because of the resurrection:

katjarella recently wondered about Nic's project of "self-playing executable media files", she just forgot the name of the project, and I was not successful in guessing good search queries.
