Tranzcode 0.40 beta

[DSP8000]

Hi,

here's an installer for Tranzcode v0.30 incl.TranzGUI v1.4 (http://members.iinet.com.au/~isdmultimedia/files/DTS%20Tranzcode%20v0.30.exe) by kurtnoise.

Hope that helps.

Regards,

Can someone tell me where to find the GUI for tranzcode? I have been looking for it but cannot find it.

http://www.needfulthings.webhop.org/ takes me to doom9.org
That´s right - interesting - the site is offline since 2 month and you are the third who remarked it . I will bring the site back after my holidays

Edit: BTW nice installer :)

[raquete]

it's not in the read-me and was hard to find the solution:

to extract 6 mono .waves using TranscodeGUI, first check "6 mono wav" or you get 2 channels even trying to select this option after load the track (the GUI refuse the option)

bye. :)

[Kurtnoise]

@Austin : any chance to share the sources of the 0.4 beta ?

I would like to add stereo downmix and pipeline...

[Austin Forgotten]

Hi Kurtnoise13,

Sure, just give me a few more days to finish off some work I did (past couple of days) I'm working on adding Range commands. I also need to clean up the source code, make it more presentable. :)

I think I fixed those bugs I mentioned (when posting the initial .4 rel. several days ago) that left back in March when I temporarily abandoned it. Still need to do a bit more to get the Two-Pass feature since it uses 64-bit on the 1st pass (arrh... decoding a 1hr+ .ac3/.dts to 6 mono wavs takes loads of disk space, not to mention adding the final output resolution on top of that!).

As I mentioned, I had also started the Range commands where you could select start and end positions either by time (in msec or h:mm:ss.sss) or samples, or frames, for decoding to wav, and also for splitting/trimming possibly inserting of DTS/DD files (with similar characteristic i.e. silence) at frame "boundaries". Of course with splitting DTSWav/DDWav I'd have to make adjustments to the wav header.

Kurtnoise13 are you going to update/modify "TranzGUI" to take advantage of the new features available in v.4? I downloaded BeLight yesterday but didn't see a Tranzcode interface on it. Eventually I'll need to write a dll which you/others could more readily use. I have done some work on my own GUI, but am a long way from seeing that project through unfortunately.

[Kurtnoise]

Hi,

are you going to update/modify "TranzGUI" to take advantage of the new features available in v.4?
Yep...that's why I asked this. ;) I already tested dts/dtswav/ac3/ddwav files + bits depth & Resampling features with the last beta and all seems to work fine. Keep up the good work.

[Austin Forgotten]

Thanks buddy, this takes a great weight off my shoulders since everyone is asking for a GUI right now :D. This allows me to spend more time in developement (i.e adding new features etc.).

(I fixed a little bug which has no effect on output - seems the /i (info cmd) shows wrong value for sync interval, this is just extra useless info-not important)

-AF

[Austin Forgotten]

Hi Kurtnoise13,

Sorry for not making available Tranzcode's current sources just yet. For the record I've been working it this past week, trying to finishing some cmds I started (twopass, peak scan, gain are all related as well as starting the "range select" feature, I mentioned earlier). They prove more difficult than I expected, especially after taking a 6 month hiatis on that project. If you can wait a little longer (hopefully within a week, but you never know how things might go).

- Austin Forgiveme

[Austin Forgotten]

Arghh.. bugs bunny alert:

Looks like the batch processing was broken since mid Feb! :( .

Seems I forgot to initialize DTS/DD files processed after the 1st file when I made modifications to the code!! So as long as you don't try batch processing of DTS/DD files with v 0.4 you won't notice it. Guess I hadn't done any testing on that for awhile :P.

Sorry about that, just found the problem today.

[Austin Forgotten]

While testing the two pass 64bit flt temp file demuxed to monos of a lesser bit depth, I came across another bug to add to my collection!

Testing the beta release, I also found the error when bit depth converting only (resampling + bit-depth conv works!) of multichannel wav to mono files crashes. I've tested 64f & 32f to 16 bit. Not sure if it fails when increasing bitdepth. Looks like a simple "switch var" for logic causing buffer allocation to be incorrect. Shouldn't be much of a problem to fix (I hope).

[xbox360]

Hello to Everyone, im using Tranzcode v4.0.0.1 & the program crashes when I do batch muxing for DTSWav ( D:\ConvertXtoDVD\Thee\Tranzcode.exe "004.wav"*005.wav*006.wav*007.wav*008.wav*009.wav* /16 /48000 ) Any Ideas ?

[Kurtnoise]

This has not been fixed yet I think. Use v0.30 instead...

[Austin Forgotten]

@ xbox360: Yes I'm aware, I think I've fixed that now, I've also fixed several other bugz too, but I also have included some new code to complete 2-pass which was a pain-in-the-p-ass. I have a couple more things to clean up, hope to release new non-beta as soon as possible. Sorry for the delays, sometimes I work on diff things related to Tranzcode (future enhancements), I think about something and then I'll see if I can do it, later to go back and continue something I put on hold for awhile.

@Kurtnoise13, I've not forgotten about the source code. I've decided to write my own gui version (not just a gui, but a windows app). Once I've released that I'll post the console source. Guess I didn't want you to get a jump start on me :)

It might look something like this:

(it doesn't work it's just to show you I have begun work on it)

[xbox360]

Wow your GUI Rock's, just dont forget to add batch conversion.

[daphy]

Hiho,

I just revisited this project after a long time - I just add the commands for the actual beta (0.40)
The progress is amazing :p
Tranzcode v0.40 (beta) rel. (March 2006)

http://tranzcode.byethost22.com/

Tranzcode.exe is a console (commandline) application (i.e. requires command entry in a "DOS" window)
To run it, open a "Command Prompt" window in WinXP found in the "Accessories" folder (black windowed icon)
Either copy Tranzcode.exe into your i.e. 'C:\WINDOWS\system32\' directory to save you the trouble of setting it's path or copying it into every directory where your working files are located.

Here is a quick guide to help you run some commands using Tranzcode. (Tranzcode commands in a nutshell)

When executing any commands in the console, use double quotes around any dir path or filename that you enter which contains any space characters.

i.e. tranzcode "my ac3file.ac3"

or tranzcode "D:\wicked dts files\test.dts"


If you do not specify the output prefix name, then Tranzcode will use the source name and append a channel identifier to label the channel [i.e. <source name>-FL (means Front Left channel)]

tranzcode "dtswav test file.wav"

result will output several mono wavs depending on the number of channels found (i.e. if 5.1) The output filename are: dtswav test file-FL.wav, dtswav test file-FR.wav, dtswav test file-C.wav, dtswavtest file-LFE.wav, dtswav test file-SL.wav, dtswav test file-SR.wav

Where:
FL = Front Left channel
FR = Front Right channel
C = Center channel
LFE = Low Frequency Effect channel
SL = Surround Left channel (Back Left)
SR = Surround Right channel (Back Right)

** Note: Most options do not require specific order **
** Also options can be upper or lower case **

But.. some options do not work with others, you will be notified about those. Hopefully I caught all bad combinations.


Specify which channels you want decoded using '/+' or '/-' options
=================================================

(By default all channels will be decoded.)

examples:

tranzcode test.ac3 /+FL,FR (only decodes Front Left and Right channels)

tranzcode test.ac3 /-C,LFE,SL,SR (if this is a 5.1 file then it does the same only decodes Front Left and Right channels) (using '/-' cancels the channel output)


Transcoding DTS [.dts, .wav (dtswav), .cpt] & Dolby Digital files [.ac3, wav (ddwav)] to Mono wavs.
===========================================================================

examples:
tranzcode test.ac3
tranzcode test.ac3 /-LFE /16 /44100 (cancels LFE channel, outputs 16 bit integer wavs at 44.1Khz)



Transcoding DTS [.dts, .wav (dtswav), .cpt] & Dolby Digital files [.ac3, wav (ddwav)] to a Multichannel wav.
================================================================================

examples:
tranzcode test.ac3 /mch /-LFE /16 /44100 (cancels LFE channel, outputs a 16 bit integer, 44.1Khz multichanel
wav)

tranzcode test.ac3 my_multichannel /mch /-C,LFE /16 /44100


Get the file information about the file: [ /I ]
============================

examples:
tranzcode test.ac3 /i [this will show calculated info (quick)]

tranzcode test.ac3 /im [this will show measured info (slow for .dts, .cpt, .ac3, dtswav, and ddwav)]


Operate in quiet mode (no progess is displayed): [ /Q ]
=====================================

example:
tranzcode test.ac3 output_files /q


Disable Adjust: [/A]
============

example:
tranzcode test.ac3 output_files /a


Disable Dynamic Range Compression: [/R]
==============================

example:
tranzcode test.ac3 output_files /r


Disables channel decoding to mono wavs for regular wav files (not applicable to DTSWav & DDWav): [/X]
=================================================================================

(Lets say you want to resample a multichannel wav, by default it will demux the channels to mono wavs, the /x option will not demux, this allows dsp operations like bit depth conversion or resampling to occur.

example:
tranzcode my_multichnl.wav /48000 /x


Dithering: [/Dx]
=======

Dithering should be applied when bit depth converting form a higher resolution to a lower one.
Dithering requires an extra parameter 'x':

Where 'x' can be: (0-3)

0 = none (this is the same as not using the /D command - this may not be in future versions)
1 = no noise shaping
2 = triangular dither
3 = ATH based noise shaping

example:
tranzcode my_32bit_mchnl.wav /16 /d2


Probability Distribution Function: { /Fx, /Fx[y], /Fx[.zz] }
========================
Where pdf type (x) can be: 0 = rectangular, 1 = triangular, 2 = gaussian
Where noise amplitude (preset) [y] can be: 0 = 0.7, 1 = 0.9, 2 = 0.18 (default: [2] = 0.18))
Where noise amplitude (user entered) [.zz] is within the range: (.10 to .99)

tranzcode my_32bit_mchnl.wav /16 /d2 /f1[2]


Bit Depth Conversion: [/8, /16, /24, /32, /32f, /64f]
================

/8 = 8-bit integer output
/16 = 16-bit integer output
/24 = 24-bit integer output
/32 = 32-bit integer output
/32f = 32-bit floating point output
/64f = 64-bit floating point output

examples:
tranzcode my_32bit_mchnl.wav /24 /d2 /x

tranzcode my_ddwav.wav /16 /48000


Resampling: [/44100 , /48000, /96000]
=========

/44100 = 44.1 kHz output
/48000 = 48 kHz output
/96000 = 96 kHz output

example:
tranzcode test.dts /16 /44100


Interleaving (muxing) mono wavs have same characteristics to a multichannel wav.
==============================================================

example:

tranzcode chnl1.wav*chnl2.wav*chnl3.wav*chnl4.wav*chnl5.wav*chnl6.wav my_6channel.wav /+FL,FR,C,LFE,SL,SR

where (FL,FR,C,LFE,SL,SR are the speaker assignments) Yes this is where '/+' option has a dual purpose.
the channel should be in the correct order as they are listed 1st to last.

example:

tranzcode chnl1.wav*chnl2.wav*chnl3.wav*chnl4.wav my_4channel.wav /+FL,FR,BL,BR



Batch processing:
=============

You can run a batch job on several files, which have the same output specifications, by using the '*'
character a a delimiter.

example:

tranzcode "test 1.dts"*test2.dts+"test 3.ac3"*myddwav.wav*dtswavtestfile.wav /16 /44100



You can halt execution of a run Tranzcode process by using the old [CTRL-C] (Control Key + C key)
You can then load the unfinished output files into an audio editor to view the current progress of the file, or use it to suspend process till you make more disc space available on the drive. Then as prompted hit the 'Y' or 'y' key to continue execution, or any key to abort the process.


Well that's about it for now, hope you find this useful, sorry other commands are not available, like '/S' for dowmix of multichannel audio, or '/T' for Two-pass operation to check for clipping of peak values to lower the gain, or a gain, normalization feature, or... well that's why this is a beta version from March (I was doing other things since then) :).

keep it up buddy :thanks:

[Pookie]

Fantastic app, one of my favorites.

[old-hack]

What should the size of a transcoded dts or ac3 file be compared to the original?

i.e. original dts file = 445683 KB

tranzcode file.dts file.wav /mch /44100 (file size = ?)

right now my wave file is 2 gigs and growing

added: my tranzcoded file ended up being 5 gigs.

thx

[old-hack]

I guess I thought "Tranzcode" meant that it would transcode a dts or ac3 file into a wave with a size and format recordable on a CD. Obviously the wave file created must be re-encoded to an AC3 or DTS wave.

[daphy]

yep :p

The results 2:04:16, 1:22:51, 1:02:08 are wrong.
If the filesize is ~= summ of 6 wavs you have a usable multichannel wav of 2:16:00.

I say usable but not correct because there are two fields in wav header erroneous (Riff and DataLength). These fields are 4 bytes long and can't save a number greater than 2^32 = 4 G.

This limit (4 GB) is reached with:
(16bit/8) * 6 chan * 48000 samplerate * (2:04:16) sec
(24bit/8) * 6 chan * 48000 samplerate * (1:22:51) sec
(32bit/8) * 6 chan * 48000 samplerate * (1:02:08) sec
but your files contain more data.

The problem is how use this wav files rejected by many audio software.
- To edit the wav's is recommended use mono/stereo to avoid the problem.
- To merge/split channels you can use WaveWizard
- To encode to ac3/aac you can use Aften/NeroAacEnc, both accept wav files > 4GB (use -ignorelength with NeroAacEnc).
ERROR #2

why not muxing ??
Sorry I'm not test Tranzcode like muxer. Maybe is the same problem with the overflow in header fields. You can use WaveWizard instead (check Ignore Size in Header).

Edit: You can use also BeHappy/Bepipe with AviSynth to decode (NicDtsSource), make some edit (resample, timestretch, downmix, ...) and encode to ac3 (Aften), aac (Nero or CT), ogg, flac, ...
All without intermediate wav files.

I think you forgot to add the '/mchn' option, or was it '/mch', anyway I've replaced it with the '/m' option in the new ver (not out yet)

You can also try without the specified name and channels

i.e. without the "island-6ch.wav /+FL,FR,C,LFE,SL,SR"

just type...

tranzcode island-FL.wav*island-FR.wav*island-C.wav*island-L
FE.wav*island-SL.wav*island-SR.wav /mch

That error has nothing to do with the length (format [hh:mm:ss])

Tebasuna51 is right about explaining the length since the wav header is limited to holding a value just over 4GB. So when you mux to a multichannel wav the file grows large enough to surpass 4GB especially with higher bit depths.

-AF

BTW, I mentioned a new ver is on the way and I thing I said "soon". Well I guess eveyone knows my "soon" can be anywhere from a couple days to a year! I have finished the 2-pass & gain stuff, and added simple downmixing (not Dolby Pro Logic IIx), and also added stdout support and esaier batch processing via custom filters (i.e. *.dtswav, *.ddwav, *.2chwav, *.1chwav, *.mchwav) . I really wanted to have audio playback, but for the life of me I can't playback decoded samples. I've spend a week trying with DirectX, and 2-3 weeks using BASS Lib (www.un4seen.com). All source code examples I've seen playback from file, not from memory buffer. I know this is not the right place to ask for help, I'll go ask for help in the "Development" forum. I like BASS lib since it has plugins for playing back other filetypes as well as dsp effect etc., maybe I can farm out the job to someone who's up to scratch on BASS lib and knows how to implement it via ANSI C.

(frustrated Austin)

[Austin Forgotten]

I finally figured out the playback thing using BASS Lib, so I won't need to be a grouch at XMAS.

[enantiomer]

Austin, this a great tool.
You mentioned you added stdout support, but I haven't been able to figure out how to make that work. Can you give an example of how to use Tranzcode at the command line so that the stdout can be piped to another application, e.g. Aften? Thanks.

[Austin Forgotten]

Hiya enantiomer,

Thanks for taking interest in my project. The stdout feature will be part of the next version. Err... I have been working on it for quite some time as you may or may not know. I added significant more functionality, unfortunately I would like to complete those, before I release it (started several features, which need to be cleaned up). I know it's been more than a year since I reluctantly release the beta 4 which is plagued with bug, since there was pressure to release. Every now and then a bug will stiil appear :(.

I know that I've also hinted at a near release, but ended up starting another thing that interested me, which I might be able to add to Tranzcode, eventually delaying it's realese. The thing is allot is tied together, so till I have the whole thing working flawlessly err.. umm well close to it, then it will see be presented. Uhh.. I should mention that although I did do some gui work on it 4 months ago, I abandened it temporarily to spend time on add more features. Once I get those things working the way I want, I'll focus on the gui. For all you mouse clickers out there, I'm sorry about that, but I'm the only one working on it, and I'm doing the best I can. Hopefully there will be something within a month or 2, that's all I can promise (Really!) [a console ver that is].

[mumdigaueln]

Hi,

I tried to process a dts file which /im reports as follows:


filesize : 579,803,070 bytes
filetype : DTS Padded
channels : 6 [5.1]
bit depth : 16 bit integer
sample rate : 48,000 Hz
bit rate : 768.00 kbps
length (time) : 6,147.680000 seconds [1:42:27.680]
length (samps): 295,088,640 samples
frames : 576,345
framesize : 1,006 bytes
snc interval : 1,006 bytes
sync word fmt : 16 bit
amode : 9 [FL,FR,C,LFE,SL,SR] (multich wav compatible)


When I start tranzcode without additional commandline parameters, I get six 32-bit flt wav files. Why 32-bit, input is 16-bit?

When using /16 tranzcode reports


Additional dsp: [bit depth: 32-bit flt --> 16-bit]


Obviously, tranzcode treats the input file as 32-bit file while processing.

When applying /d2 with or without /f2, tranzcode crashes. Some dll missing? Or bug?

Any help highly welcome. Thanks in advance.

mumdigaueln

[ACrowley]

32bit Output is correct on DTS Files

[mumdigaueln]

32bit Output is correct on DTS Files

What does that mean? The dts file itself has 16 bit. When being transcoded to wav it is "normal" that the bit depth is converted to 32-bit? Can you explain that?

And why the crash when trying to apply dithering?

mumdigaueln

[Austin Forgotten]

Hello there mumdigaueln,

You say that "When applying /d2 with or without /f2, tranzcode crashes". Actually I'm not surprised by that as the more I add to Tranzcode, the less time I have to fully test every option fully. I would advise not to use any dithering when down bit converting. I'll have a look at this. The dithering code as well as downbit converting and resampling was taken from ssrc source code (ssrc 1.30) (http://shibatch.sourceforge.net/)

To explain why the /im option says the file is a 16-bit dts, and the output is 32 bit floating point which you probably want to have as 16 bit wav output, you may find some info in a readme file. Basically I used libdts (renamed now to libdca) to decode dts, which THANKFULLY decodes to 64 bit floating point samples (i.e. doubles), why this is a good thing is because you can perform high level dsp (i.e. resampling) operations and retain the highest quality output. Thus tranzcode does all it's dsp at 64 bit floats (doubles) and then allow the user to select which resolution they desire.

Since 64 bit floats is not too popular as a default wav output I decided to default to 32 bit floats. If 16 bit integer output is desired I down convert it from 64 bit flts, which is an extra operation, which I let you know about it.

The /im command describes some attributes about the source file, apparently the dts file in question was originally encoded with 16 bit mono source files.

Err... as you probably already know, the multichannel output has a few errors in the (ext) wav header, which I've fixed in the unrel ver. You are advised to use another app (i.e. wavwizard) to mux the mono wavs output.

[mumdigaueln]

Hi Austin Forgotton,

thanks for your reply. If I understand you right, you propose to just let Tranzcode convert to mono wav files without any dithering and bit depth conversion. That will force me to do one step more, i. e. transcode (from 32-bit) to 16-bit mono wav's (including dithering which - as I learned - should always be applied when going down), as the program I use to encode to ac3 (Sonic Audio Transcoder which is part of Scenarist, but can also be used standalone) just accepts 16-bit wav's as input. This additional step is ok for me, as long as the quality is pertained as much as possible. I think I'll use Sound Forge or Audition for this intermediate step.

Best regards

mumdigaueln

[Mtz]

Do you have some link for Tranzcode GUI?
