David,

I'm not saying that I'm one of them, but don't be surprised if you get volunteers from this site to help you out with the batching suggestions, etc.

BTW, I have had no trouble at all on my Win2K box. Bidule hauls *ss!

Bidule is a realtime experimental music creation studio primarily

We'll think of an easy way to do such a thing that woulndt take too much time to implement. Suggestions are welcome.
I understand.

Thanks for listening to my suggestion,

Hi folks,

back from a hard (and I hope last business trip this year) I noticed much happened on my favourite board!

Thx to David for the new bidule! I am looking forward to do some testings this week.

joshbm wish list
for me one feature on this list is most attracktive:
optional output with 6 single monofiles.
To integrate a AC3/DTS encoder would be a nice thing in the future, but for now this output option would save much time!

@joshbm

did you some tests with the new bidule version and your 5.1 solution?
is some rewiring necessary?

something I remarked:
5.0 with DTS on all tested Amp (mostly Yamaha) sounds fine - even the bass. I also find out that most of the DVDs in DTS are 5.0.
5.0 with AC3 suffers under less bass, so for this case a 5.1 transcoding methode would bring some exciting improvements in bass.
That“s why I also did some further experiments with 5.1.

Shoot what a speed increase. Been playing for a couple of days now flawless and fast!

Test are greatly increased and still looking at tweaks and my new amp to arrive till batch mode kicks in.

Thanks again great work here

@daphy:

Yeah, some rewiring was necessary. I have a really excellent 5.1 solution as well. I would release it, but there are 2 or 3 more plugins required besides the ones already listed (mostly for the bass and to make the sound more clear).

If you would like me to post it I can. I added the following:
- Group version does not work for me because it takes up too much CPU usage (on my comp), so it is a .bidule file.
- Reverb option
- Baxxpander (cool wave expander-- making your sounds more crisp including the bass)
- X-cita, which defines the treble sound.

If I could make a 32-bit float ac3 (with ac3enc, which I don't know how to do) I would post a sample.

Regards,
- joshbm

Hello Joshbm.

Can You post the new way to do stereo2dd5.1? How do You get 6channel
32bits wave file?
As EoH says don't use never free ac3enc because it is now very bad encoder.
Forget it.

I have tried the new Bidule and all the exe updates
posted here, but I have this one rather
annoying problem.

I get 4xnormal speed with my 1,7ghz (running Xp Pro) when I set the
buffer size to 512k, at 256k it is as slow as ever.

But, with the speed increase, the program skips
the first 4 or so seconds (I'm trying to do
a 32bit float, 48khz file of 300mb) of the wav file giving
a result which is missing a few seconds...and this
is a major problem when the audio is
destined to go to DVD ;-)

I could not get past this
by any other way than slowing the thing down to
the good..erhm..bad old real time processing, where
the file is processed to the full length and nothing
gets skipped.

Just an FYI on something I just did...

Took a 32-bit 73 minute - 1.5GB wav and Biduled it with the normal 5.1 setup, offline processing, into a 16-bit multichannel wav.

Resulting file was 2.2GB.

Out of curiosity, I opened the file in Cool Edit 2.0...took a few minutes, but six wavs opened, and in single-wav view, each wav was a mono 379MB file. The naming scheme used by cool edit was AID1 (original file name), then AID1(2), AID1(3)...and so on to the number 6. The number 4 wav was empty, but each other wav was mono and just a little different-looking than the last. Used the SAVE AS option to save the first one as FL, the second as FR, the third as C, the 5th and 6th as SL and SR, respectively. Bully on the blank one, I leave the LFE empty in Surcode, anyway.

(I quit using Besweet-to-dts automation for now...Surcode has been crashing when called by Besweet lately. Don't know why.)

Surcode rejected the FL file, the first file saved (and without a number) telling me it needed a mono file, so when I looked at it in Explorer it showed up as a 2.2 GB file whereas the rest were 379 MB files (like they were supposed to be).

That FL-file still showed up as a 379 MB mono file in cool edit when I opened it...and it split into five other mono wavs just as the original one did before I saved as speaker assignments. Weird how this file is still considered to be a multi-channel file, but yet also as a mono, as well.

Don't roll your eyes at me, Scully...might just have to do with the different header-naming scheme that DSPGuru spoke of.

I ran that "mono" FL file through cool edits "resample to mono" option, saved it again, and it finally showed up in Explorer as a 379 MB mono file, was accepted by Surcode, encoded with the others into a dts file, and the heavens screamed with joy.

But I'm out of blank CD-Rs, can't try it out as a dts CD on the DVD player yet.

Anyway, I like to read every bit of information on everyone's experiences, so I just thought I'd share.

Hi folks,

me and @ndy have installed a special ftp server (with upload option) to give everyone of you the posibility to spend his bidules/groups/infos/own guides ... (no illegal stuff of course, please!)

have a nice time with it

Merry X-Mas


Ambisonic Server(new link)

@daphy: Thanks for the initiative.

As a 1st contribution, I'm adding a newly designed bidule which uses the Panorama-VST. It's currently in the "/Ambisonic/upload"-directory, but you might want to sort it differently.

Some explanations:
Code:
I think it basically achieves the same as
the 'old' one.  Maybe it is slightly better, as it
processes internally as 2nd-order-B-format (within
Panorama), whereas B-Pan "only" does
1st-order-B-format processing.  I don't yet have
enough samples to really call this a "firm" statement,
so it's just a working assumption currently.

Some notes to the settings (see 2 attached JPG's for
illustration):

(1) Elevation:  I put that from 0 to 0.55 (L & R), to
tilt the soundfield slightly upwards by 33 degrees.
This is because my speakers are all very close to the
floor.

(2) Distance: I out that from 3.70 to 5.05 (L & R),
which slighy enlarges the size of the sound-sphere. If
enlarged too much, the VST calculates too much
reverberation for my taste.

(3) Azimuth:  For "L", set to +2.20, for "R" to -0.94.
  This only applies to when decoded to Pentagon.

For Square-decoding, it would be +1.57 for "L", and
-1.57 for "R".

Why the change (Square --> Pentagon) ?
  - "L": +1.57 --> +2.20
  - "R": -1.57 --> -0.94

Remember that we turned the soundfield
counter-clock-wise by 36 degrees, inorder to have it
correctly aliged to the 5.0 (or 5.1) speakers in people's
living-rooms.

We have to do the same here, i.e. rotate
counter-clockwise by 36 degrees, which corresponds to
an an increase of +0.63.  Meaning:
  - "L": +1.57 + 0.63 = +2.20
  - "R": -1.57 + 0.63 = -0.94
Comments & suggestions welcome here in the forum.

Happy Xmas to all
Andreas

P.S. joshbm: don't forget us ...

Just a follow up since i rambled on about this problem for so long in this thread.

It appears that the clicking problem has been fixed in Besweet by DSPguru in the latest b24. Clipping at the first .002 seconds on 32 bit float waves is gone.

Since there is two versions of the latest beta you need the latest.

http://forum.doom9.org/showthread.ph...052#post417052

or home

Edit:

With regard to the process and the guide. I find the LFE input nice on dts and therefore have been using it. I remember the warnings about using it in the beginning on this thread.

What i have found is you need to watch to make sure that the lfe channel is not the controlling wave in the normalization process. This is the case with the graph suggested. This is dangerous and really does not normalizes. What i have done is add gains to the lfe channel between HNM and the recorder (3 would be required). I have found the default -3.33 db is a good setting but my testing is young (ed : -5 in most conditions?). This ensure that the normalization is carried out on C, F, or rears and not "pump up the volume".

Peace

Conversion between UHJ and B-format using SIR (Super Impulse reverb)

From Shayne Dec 11:
Quote:
What we need is all this put together in a MP3 player that joins all these filters and outputs a play list to a temp.ac3 file in small chucks and then sends them out spdif. The 3 gain filters can be user adjusted and voilą a player that would definitely out play anything we have now. I am sure its thought of and in the works.
I think we are basically there. At least for "wav/mp2-in" --> "6-channel-out", it works beautifully here with Bidule and SIR (Super Impulse reverb).

A few (selected) details on the SIR-VST:
Code:
- This is a reverb device that works with "impulse-responses".
Impulse-responses are generated by recording short, broadband
signals and their corresponding room-reflections, and by cutting
out the initial signal. What is left contains the information
needed to reproduce the same room with other signals.
- SIR is a stereo plugin. To take full advantage of
stereo impulses for mono signals, you must first convert
the track to stereo.
- Features:
  - performance optimised
  - wave-file import 24-32 bit
Angelo Farino already published an outline Conversion between UHJ and B-format using SIR for AudioMulch, which is pretty self-explanatory, so I wont' dulpicate here.

I've written a small bidule which does the same as outlined Audiomulch contraption (I can upload it to Daphy's ftp if there is interest).

In summary, this achieves the same as the initial Ambisonic Guide by EoH , but with the new tools in real-time (or "hyper-speed" with the offline-mode).

A few notes:
- make sure you use the "right" impulses with your source (i.e. 44.1kHz 32-bit pulses on source=stereo_wav with same properties)
- "M2Buss" in AudioMulch translates into "AudioMatrix" for Bidule
- I personally prefer Bidule, but this is my personal taste (think it's more intuitive to use, more straight-forward)
- Filtering-impulses are also available from A. Farina's Site
- You might want to play with the settings for 'dry' and 'wet'. As a starter, I recommend 'dry'= 0 dB, and 'wet0= -6 dB.

Cheers,
Andreas

Hello Kempfand.

Thank You for your work with Panorama Vst plugin. Can You upload Bidule with SIR VST Plugin?

I think "initial Ambisonic Guide by EoH" gives the best DD5.1 output,
How do You think?
