UpmiX: tool to automate stereo to 5.1 conversion (v0.71)

[KpeX]

UpmiX has evolved into a tool to process many kinds of stereo audio into 5.1 AC3, MP4, or 6 wavs. See this post (http://forum.doom9.org/showthread.php?s=&postid=480270#post480270) for information on the current version. The current download link is: http://dhost.info/kpex/UpmiXv0.71.zip (right click > save as)

Original post:
I'm not sure if this will be useful to anyone or not, but it's worth a shot.

I've put together a brief guide and AviSynth script that automates the upmixing process from stereo sound to 5.1 Dolby Digital using all freeware programs: AviSynth, BeSweet, SoX, & Nic's Call plugin. It's nothing very complex or technical [edit], it merely does some low- and high-pass filtering, normalization to different levels, and resampling. Input is any 2-channel wav file, output is a 448 kbps 5.1 DD 48000Hz AC3 file. This process was designed & tested on music, mostly hard rock or techno, but in theory could be used for movie soundtracks as well with some tweaking. This method doesn't do anything spectacular, but it is fully automated and really demonstrates the power and flexibility of AviSynth together with Call and BeSweet.

Feel free to post any comments, questions, suggestions, etc. Thanks to anyone who tries it.

Edit: Please see below for new method

[KpeX]

If anyone's interested, I've uploaded a 25 second sample of a song encoded by this method, one sample of the encoded AC3, and one of the original 2 channel wav ripped by EAC and compressed for size purposes via lame --alt-preset standard. Get it here (http://www.freewebs.com/kpex/EncodeAc3_samples.zip).

[KpeX]

@ kempfand:

Just to make sure i'm understanding you correctly: you modified the script for DTS encoding ? I'd be interested to see your changes if you don't mind posting the script. I was actually kind of hoping someone would come up with a DTS-script because I've never experimented with it. ( My amp doesn't decode DTS )

Edit: getting back to quality issues: I doubt this method will be very comparable to EoH's method, post length would be the first clue ;) However I like it because it's automated and it works well for music: It produces a similar sound in all channels, based on what ranges/volumes those channels are suited for.

[KpeX]

Very cool, Andreas. It's also nice to see BeSweet back in active development. I've also come up with a semi-automated method for encoding CDs: EAC --> 5.1 DD, if anyone is interested let me know and I'll post it. Filenaming is not automated, however, one still has to type in the filename at the end of each encoded track.

[KpeX]

Well, here it is, my somewhat-automated method to encode AC3 right from EAC ( Exact Audio Copy ), the best CD ripper out there. If you tried my other AC3 encoding script, this is pretty similar. Here are the steps:

Requirements
============
1. Latest BeSweet beta and dll's. (http://dspguru.doom9.net)
2. AVS2AVI CLI encoding tool. (http://forum.doom9.org/showthread.php?s=&threadid=36768)
3. AviSynth 2.5x.
4. Nic's excellent Call plugin (http://www.avisynth.org/~warpenterprises)
5. Sox CLI audio tool (ftp://ftp.externet.hu/pub/mirror/sac/sound/sox12174.zip)




1. Download EncodeAC3v0.2.zip (http://www.freewebs.com/kpex/EncodeAC3v0.2.zip) (Right-click - save target as)

2. Unpack the contents to the same directory as you have the latest BeSweet beta, including the latest ac3enc.dll. Also put sox.exe, call_25.dll, and avs2avi.exe in the same directory.

3. Configure EAC: Set EAC options to save files in the directory mentioned in #2 as shown here (http://www.freewebs.com/kpex/EAC_options_1.gif)and set the compression with the path to the EAC_to_AC3.bat included in the zip file as shown here (http://www.freewebs.com/kpex/EAC_compression_options.gif).

4. Highlight the tracks you want encoded, and click the 'MP3' button in EAC. Each time a track is compressed, the compression will pause ( Please press any key to continue... ) at this time you can rename the file to its correct name, the .AC3 file will be in the working directory and have the name 'DolbyDigital5.1Audio.ac3'.

Notes: Make sure you don't have any other .wav files in the directory being used. This probably isn't the cleanest way to encode AC3, but it's nearly automated and hopefully will be useful. As usual, thanks to anyone who tests this method, and feel free to post any comments and suggestions or other experiences. Hope this helps,

Hello,

I downloaded your tools a few days ago, and last night I played around with it. I used the P4 modified VirtualDub 1.5.1 to encode the .AVS, it appears that you have changed to a new App? The AVS2AVI CLI encoding tool? If so, please update your website. This is a very interesting idea you have going here. Being able to encode to 5.1 or DTS has some possibilities. I am pondering a GUI written in VB if I get some time. I will probably use some "AppActivate/SendKeys" to hook the apps, but what I want to do is add Slider Controls to the EQ variables, to be able to modify them on the fly, to get different setups easily and also to add a Automatic Output file naming routine. I will post the app if I get around to it. I am following this thread eagerly and hope many jump on board with this idea. Perhaps merging some of this idea with the "Virtual Microphone 5.1" idea may be possible. Hey you should give this project a name, like the "Kpexer Project" or something and a Version number, so we can track and improve it. Thanks for your work.

VidHack

[VidHack]

Messed around with your new encoding method. I originally downloaded your tools a few days ago. I was using VirtualDub and BeSweet Version 15b18 with an older AC3enc.dll (v0.21) - All was fine.

So, I downloaded this new way, using avs2avi (CLI), got the newest BeSweet 15b19, and fired it up. Well BeSweet spit out errors on every pass. I need to add the -log option to get some debugging going, but I figured you would want to know.

Also, added the -q option to your EACtoAC3.bat, and remmed out the 'Pause' (speeds everything up.

VidHack

[KpeX]

@ Vidhack

1. Thanx for testing :D

2. It doesn't matter what you use to encode the AVS script. AVS2AVI was just what i used for the EAC guide because it was easier to call in a batch file. Perhaps I should clarify that there are two methods for this, encoding individual scripts or using the EAC batch file.

3. The 'pause' in the script is for renaming of the file (i.e. artist - trackname ) if it isn't renamed, it will be overwritten by the next file. This is one of the limitations of this method, it's more of a quick and dirty solution than anything else. What effect does -q have? I'm not familiar with that.

4. The two zip files I already uploaded are numbered (v0.1 and 0.2)

5. I hadn't really considered giving this an 'official' project name or actually licensing/releasing it, because it isn't really a program, it's just an AviSynth script that calls BeSweet, I'm no programmer, but feel free to base an actual tool off of any of these scripts/concepts.

6. Your conceived app sounds great, please do post if you code it.

7. I will update my site soon with the EAC guide, reflecting my previous post.

8. Edit: forgot, about your besweet problems, I upgraded to b19 with no problems.....did you make sure to put ac3enc.dll in the directory? what is the nature of the error messages? aside from that, yes a logfile might help.

[KpeX]

Update: Html EAC to AC3 guide is now on my site (http://www.freewebs.com/kpex/EACtoAC3.htm). Thanks to anyone who tests, when having problems, make sure you are following the guide correctly, and post the exact error message and where it occurs. Hope this is helpful,

[KpeX]

New scripting method, now uses batch file rather than avs script, it is now much cleaner and more efficient, and is now fully automated with automatic file naming. Basically just download my latest zip archive (http://www.freewebs.com/kpex/encodeac3v0.3.zip) and see here (http://www.freewebs.com/kpex/eactoac3v03.htm) for specific EAC configuration options. I threw the guide together rather quickly so feel free to post any problems/questions.

Edit: Almost forgot: if you just want to encode a stereo wav and not rip with EAC, just use the batch file from command line:

Encode.bat "path\infile.wav" "path\outfile.ac3"


Thanks to any and all who test, HTH,

I edited the paths in the convert.bat.
And tried it with a tereo 44.1/16 file.
During the process it makes (as expected) the temporary files. Each is about 40 MB. It then starts Sox and when it's all finished I end up with an emty AC3... ?

Problem is I cannot find what I'm doing wrong.

The posting of Kempand's example on Usenet : I liked the effect a lot, but got the impression that the LFE channel has some distortion compared to other versions of the same album....

I.e. take out the 'del %workingdir%....'. Do you still have the channel1.wav-channel6.wav ?

If yes, something with besweet -ac3enc ( -b 448 ) is wrong.

Regarding AC3: I never went this route, since dts gives better sound (i.e. I feeded the channelxyz.wav's into SurCode CD). I have no LFE speaker, so didn't notice distortions ...

Also: add '-logfilea BeSweet.log' so we can see where things go wrong.

Hi Andreas,

I did and ended with the channel 1 to 6 WAV's.
Downsampled (the save as in SF) to 44.100/16 and had no problem encoding them with DTS Encoder.

I'll do it again with the logfile and add it here, but I must mention two things from extensive listening that it a. lacks a bit clarity (Could that be because work is done directly on the 16 bit Wav's. Remember the notes from the Aurora writer about 32 bits ?) b. there's still the distortion in the LFE. It's difficult to describe. But it doesn't sound clean ! It looks like something is giving resonance within the sound itself. I do not quite understand myself what I'm writing now !!! LOL !!

But there definitely is potential in this method !

@ EoH and kempfand: Thanks very much for the kind words, testing, and reports. :D

@ EoH:

1. About my website, I'll look into that. I use mozilla firebird so maybe I should see what happens with IE. I'm very new to handcoding HTML so I appreciate the feedback.

2. As far as the resampling, the only reason I include it in the script is an AC3 must be 48000 Hz to playback over the S/PDIF of my soundcard. If it is not necessary, yes by all means remove it from the script.

3. Editing probably should be done on 32 bit wav's ideally, but that would make things more complicated and not as easy to automate.

4. I'll look more into the LFE channel issue. What type of sound/music do you notice the effect on ?

5. Edit: Just noticed your last post. Does the same thing happen with the latest beta of BeSweet (1.5b19) ? Are the individual .wav's okay ?

[KpeX]

A little OT, but my site (http://www.freewebs.com/kpex) and ac3 guide (http://www.freewebs.com/kpex/eactoac3v03.htm) should now work with IE. Mozilla/Firebird is still better though :P. So much to learn about CSS and HTML...

[kempfand]

@ EoH:
- Try using BeSweet v1.5b19. Earlier versions of BeSweet need a 7-line mux-file to work corretly (but this 'trick' is no longer needed with the latest BeSweet).

@ KpeX: Doing the editing at 32 bit is definitely the best way to go. EoH did some extensive testing, and we also found some threats in other boards about that subject (don't have the link handy, but I posted it in EoH's Ambisonics threat).

If we can improve the LFE, it would be great to keep it in mind (could do a 'manual' test-run on a couple of songs, for comparison; if we all feel the output is better, then trying to automate the editing @ 48 kHz could we worth the effort).

Kind regards,

Andreas

[KpeX]

@kempfand

I was thinking of the older mux file bug as well, but that shouldn't cause BeSweet to crash - hopefully b19 will solve EoH's problem.

I don't think this type of editing will have a audible difference at 16 or 32 bits. I will test and upload a sample. I will probably have to edit with Audacity or something similar unless you can suggest a better method for editing @ 32 bits.

I'm working on improving the LFE channel. If you could post more specifically what improvements you would like to hear, that would help greatly. Regards,

About the editing at 32 bits : read the comments in the link Kempfand suggested. It's from the guy who wrote the Aurora tools for Cooledit.
And yes : you will hear the difference.
I did a lot of testing on this in cooledit , with and without the Aurora plugins. Of course I cannot tell if it will make a difference in your method, but it could be worth the effort !


About the LFE : as I said before : it's difficult for me to describe the distortion. I loaded the LFE in SF 6 to analyze. Perhaps the crossover at 300 Hz has anything to do with it. (I'm not technical, but perhaps lowering that to 200 Hz will improve ?)

Music I tried it on : Kempfand's PF posts and I tried a few tracks from the French group Era.....

Later today I will look for a piece of music with a clean bass in stereo and try that....

@ all:

Feel free to try this version (http://www.freewebs.com/kpex/encodeAC3v0.31.zip). Modified the lfe.eq file slightly to lower the cutoff frequency for the lowpass and lower the overall level. Hopefully this will improve the perceived quality of the LFE channel. In my system the LFE channel isn't affected much by having additional frequencies in the LFE, but I can see how it could produce distortions in other setups. Feel free to test and modify with your own ideas.

Hopefully this weekend I will find time to test some 32 bit encoding. At this point I doubt this editing is extensive enough to notice a difference, although I'm open to being proven wrong :D. thanks to all who test(ed).

[echooff]

Hi KpeX,

Love your routine. It is a snap to use. Being new to avs scripts I doubt I could modify your script and end up with a working copy. Do you or anyone else know a line I could add and where to place it that would automatically rename the out put file to Its orginal name and a -new? Like besweet does when you use his GUI.

[daphy]

Hey guy I tried this and it works :D

1.it makes me wonder:
the very low output is this my mistake?
Is it possible to 'normalize' those files -> the files from besplit (frontleft.wav ...) are ok but the files channel1-6.wav have less output!!

2. comparing the original wav with the ac3 I´m wondering whether the right and left (front) are changed

Did some testing this afternoon.
LFE sure sounds better now, but still not as clean as possible.
I'm not quite sure about the reason.
Anyway, I also encoded to DTS without the LFE and then the LFE sounds better. (My receiver can use a separate LFE channel or make it's own out of the 2 front streams).

I hope to do more testing this weekend with testtones at different frequencies.

[VidHack]

A quick favor, could you post some info/link to website regarding the (eq) settings? Perhaps min / max values, options, any technical info.... Thanks..

[KpeX]

@ all

Many thanks for the testing and feedback. Just to be clear, v 0.3 and up is a totally different scripting approach than before, avisynth is no longer used or required.

@ echooff

First, Thanks for the kind comments. Secondly, If you are using v 0.3 or 0.31 there is no AVS script, it's just a batch file that calls BeSweet and Sox. As far as renaming the file, you could try this:

Encode.bat "path\myfile.wav" "path\myfile - new.ac3"

Or if I have time i'll throw together a batch file that would name it like that automatically.

@ daphy

The left and right channels should not be modified. Be more clear on what sounds like has changed and your playback setup.

I haven't experience any problems with a loss of volume. It's very easy to normalize, open up the batch file with notepad, and in each of the first six BeSweet command lines, in the -shibatch ( ) section, add a '--normalize'.

@ Eye of Horus

Thanks very much for the testing and feedback, I will continue to tune the LFE channel. Your efforts are appreciated. :)

@ vidhack

The equ settings in my script were totally conceived by myself based on my ears and my system. If I have time I will post a page regarding how they were derived and why I chose them. As always, feel free to modify. If you want, download the
shibatch equalizer winamp plugin (http://shibatch.sf.net) and do some testing with it, just right click > options > preferences > plugins, and you can load/save .equ files, that might make it a little more clear.

v 0.35 (http://www.freewebs.com/kpex/EncodeAC3v0.35.zip) - Changes:

1. Returns an error message if directories are set up wrong or files are not called for correctly.
2. If an outfile name is not specified, the output is "infile - DD5.1.ac3"
3. If you want to keep the temporary wave files for testing purposes, add a '-debug' at the end of the commandline.

a. I changed Besweet to the latest version and the problem was gone !
b. why doesn't a separate batchfile work ?

Put this in a batch...

encode 01.wav 01.ac3
encode 02.wav 02.ac3
encode 03.wav 03.ac3

Saved as start.bat.


Running this, it stops and even disappears from screen after the first file.

c. Are you familiar with the thread :
http://forum.doom9.org/showthread.php?s=&threadid=56020
(How to Properly Encode Dolby Digital Audio (AC3))

In this guide there is a recommendation to set "dialog normalization" to the same level as the average RMS level of the wavs.
Is it possible to build this into the encoding ?

Good idea :)

also the idea to make a separat batch file!!!

CYA Daphy

[KpeX]

1. For batch encoding using this method, your batch file should look something like this:

START /WAIT cmd.exe /C encode.bat 01.wav 01.ac3
START /WAIT cmd.exe /C encode.bat 02.wav 02.ac3
....

Inserting paths if necessary.

2. Proper dialog normalization is not possible under the current method, because the only parameter that is specifiable in BeSweet's native ac3 encoder is the bitrate. Personally I'd rather keep it freeware than do it exactly 'right', but feel free to use the .wav's in a payware AC3 encoding program and do some dialog normalization and other techniques described in the thread EoH mentioned. hth,

how about to combine the dts-comandline issue (http://forum.doom9.org/showthread.php?s=&threadid=55590) with this project because of those audio-DTS-CD junkies like me ;)

why don´t update your homepage download link -> still only 0.3 avaible

Thanks for the kind words, v 0.35 is uploaded, just not linked on my site, I figured more people were following through this thread, I'll update soon.

Using dts-command line encoding should be easy, just substitute the correct BeSweet command line into the batch file.

As far as the third point - I have no idea, never used surcode. Regards,

If your goal is DTS CD's, you don't need Surcode DVD, but Surcode DTS CD ! And there are no problems with that one ! Look for version 1.09 !

PS: old Miles Davis 'Kind of Blue' (remixed in 1997) sounds PERFECT in DTS after this routine :D :D :D

I'm confused too about the versions.... I have 1.09, 1.020, 1.021, 1.023 and 1.029..... but don't know if these are all DTS CD or DTS DVD...... anyway...for use with Besure/Besweet to make DTS CD's, stick to 1.09 ! No problems at all !

And for making DTS CD's with the KpeX method.......
Don't make to many yet.... there is a major improvement on it's way..... Cannot tell when exactly, but asap :-)

oh I see, is that 'major improvment' that easy to use as the KpeX method (so the routine has get it´s own name now :D ) or like the
ambisonic method of Eye of Horus (which killing my nervs :( two hours of trying out and the result was 2 and a half minute noisy sound -> I´m shure it was my mistake :scared: but never again...)?

@ KpeX

After a lot of testing, I found out that the distortion in the bass has nothing to do with your routine (although the lowering to 200 Hz gave a better result), but with the limited ac3enc.dll !
Encoding the temporary files in a commercial encoder gives a far better result. Actually it differs like night and day !

Very funny Daphy.

But if you have any criticism on my Ambisonics guide, I would like it if you post that in the right thread or send me a personal message.
Perhaps I could even help you to get good results from that method, but to announce in an other thread how bad my method is and how difficult without any arguments, is NOT appreciated.
It's also NOT appreciated to link an improvement we are developing on KpeX's method, to your own frustrations about not being able to handle the Ambisonics method.
If it was meant to be funny, it was NOT and it's also NOT appreciated to sneer down someone's hard work.

just my 2 cents......

comparing the original wav with the ac3 I´m wondering whether the right and left (front) are changed

I already thought this, too :(

Let´s wait for the new version :D

It´s hot hot hot here in German :scared:

@ daphy and kempfand

I had some issues when developing with the super equalizer not killing the correct channel, if it's backward for you, just switch them. i.e. rename left.eq to right.eq and vice versa. I'll test when I have time, could be that something is connected backwards on my system.

Meanwhile, after all these anticipation posts, EoH, I'm waiting to be blown away ;) ( I have nothing to do with and no idea what EoH is planning)
