DSPGuru: Doesn't work. Tested on 2 independent tracks. Logfile for one:
Code:
BeSweet v1.5b24 by DSPguru.
--------------------------

Logging start : 12/21/03 , 01:11:57.

C:\BeSweet_T\BeSweet.exe -core( -input h:\01_BiD_32.wav -output p:\32-DeMux- -6chfloat -logfile C:\BeSweet\BeSweet.log ) 

[00:00:00:000] +------- BeSweet -----                          
[00:00:00:000] |  Input : h:\01_BiD_32.wav
[00:00:00:000] |  Output: FL, FR, SL, SR, C, LFE
[00:00:00:000] |  Floating-Point Process: Yes
[00:00:00:000] |  Source Sample-Rate: 44.1KHz
[00:00:00:000] +---------------------
[00:03:40:307] Conversion Completed !
[00:00:10:000] <-- Transcoding Duration

Logging ends : 12/21/03 , 01:12:07.
Resulting LFE has audio (and shouldn't), resulting SR has no audio (and should).

Just to be on the safe side: I Bidul'ed with the latest version posted by David here in the forum (dated 12/14/2003, in the RAR modified 8:30:40 PM). Not that I imply it matters, but one never knows.

I could upload a 2 sec Bidule 32-bit-wav (ca. 2 MB, start-to-end) to the newsgroups (i.e. alt.binaries.test). Let me know.

Kind regards,
Andreas

well i went through the above procedure and here are the results

pin 1 ====> pin 1 C
pin 2 ====> pin 5 FL
pin 3 ====> pin 3 SL
pin 4 ====> pin 4 SR
pin 5 ====> pin 6 FR
pin 6 ====> pin 2 LFE

This is a for sure based on the process of elimination

DSPGuru: Great job I think we are getting there.

As far as I can judge, pure de-muxing is working, both for 16/32-multichannel wav's. I.e.
Code:
BeSweet v1.5b24 by DSPguru.
--------------------------

Logging start : 12/21/03 , 21:14:18.

C:\BeSweet_T\BeSweet.exe -core( -input i:\01_32.wav -output i:\01_32-DeMux- -6chfloat -logfile C:\BeSweet_T\BeSweet.log ) 

[00:00:00:000] +------- BeSweet -----                          
[00:00:00:000] |  Input : i:\01_32.wav
[00:00:00:000] |  Output: FL, FR, SL, SR, C, LFE
[00:00:00:000] |  Floating-Point Process: Yes
[00:00:00:000] |  Source Sample-Rate: 44.1KHz
[00:00:00:000] +---------------------
[00:03:40:243] Conversion Completed !
[00:00:24:000] <-- Transcoding Duration

Logging ends : 12/21/03 , 21:14:42.
Resulting LFE.wav is empty, and resulting SR.wav has audio, both as they should.

Remarks & Additional Findings to Gaining:

(1) Peak chunk data: As I would expect, adding -ota( -g peak ) doesn't change gain (the current Bidule-out-wav's simply lack the info : Red-mark for Plogue ). This applies for both 32 & 16-bit-multichannel wav's.

(2) Demuxing a 32-bit-multichannel into 16-bit-out (using "-6ch") seems to work fine, both with "-g max" and "-g peak".

(3) Demuxing a 16-bit multichannel into 16-bit-out (using "-6ch") also seems to work fine, both with "-g max" and "-g peak".

(4) Further on: Demuxing into 32-wav-out ("-6chfloat") and gaining with "-ota( -g peak )" works fine . This applies to both 32- & 16-bit-multichannel-wav's to start with.

(5) @all: Note that my report on (5) was wrong. It probably works fine on other systems, and only produced 'scratchy' sound on my system when played through WinAmp.
Playing through CEP or Zoomplayer is perfect without any 'scratches'.


Lastly, the following 2 combinations produce a really 'scratchy' sound:
--> 32-bit-in demuxed to 32-bit-out with -ota( -g max )
[ i.e. C:\BeSweet_T\BeSweet.exe -core( -input i:\01_32.wav -output i:\01_32-DeMux- -6chfloat -logfile C:\BeSweet_T\BeSweet.log ) -ota( -g max ) ]

--> 16-bit-in demuxed to 32-bit-out with -ota( -g max )
[ i.e. C:\BeSweet_T\BeSweet.exe -core( -input i:\01_16.wav -output i:\01_32-DeMux- -6chfloat -logfile C:\BeSweet_T\BeSweet.log ) -ota( -g max ) ]

In other words: Whenever demuxing into 32-wav-out ("-6chfloat") and gaining with "-ota( -g max )", the resulting mono-wav's are 'scratchy'.

question on next steps deleted

Hope this little feedback was not too confusing and hope I got it right.

Kind regrads,
Andreas

4) "-g peak" works fine and this is my advised commandline, so why don't you use it ?
5) may i see the logfiles ?

It's the preferred commandline here too, but it (currently) doesn't normalise/gain-adjust (if I understand correctly). Not that it really matters, as it's just a question of turning up the volume a bit when playing.

Logfiles follow below, but 1st let me state, that I made a mistake here, and reported an error too quickly. The sound is 'scratchy' when I play through winamp v2.9. This is what I usually do.

However, I now openend the resulting mono-wav's in CEP as well as ZoomPlayer. Surprise surprise: It plays perfectly. I don't know what's going on here, but it means for me avoiding WinAmp in the future. Sorry for that (I'll change my post above).

In summary, it works as it should. I didn't test test the 2GB/4GB-thing, but this is no big deal, as slighly over 66 mins will fit into a biduled 16/32-output (when respecting a 2GB/4GB-barrier).

Again many thanks for the quick adjustments in this busy time.
Take care,
Andreas

this is good news. cheers, kemp!

note : i updated the b24 archive.
it is now safe to always use the "-g peak". if BeSweet will find that the PEAK chunk is missing, it will use "-g max".
(so the sound will be normalized anyhow)

btw,
please encourage david to re-enable the "peak" chunk feature.

my results on the new beta 24B (above)

Clipping at the beginning of waves is gone here

g peak normalization is working

Pin out back to old (daphy check kempfand guide jpg previous page)

Thanks for the update ...... U the Man DSPguru

same beta number is a bit confusing with such a change

Peace

I think we need to 5hit this man down beside my denon and ask if its 32 bit or not.

92 ripped since the latest beta2, Norm OK here. spot checks and 100% listen lfe gain -5 DB .... purrrfect ? 1010 to go ....... batchen.

Thinken cd sales r going to pick up here again. KooL

besweet 1.5 b25

@DSPGURU

we tried several times to split a 6WAV with correct mapping (without success) - then I found the latest besweet version (1.5b25) on the beta section - and all of our problems are gone


genius work!

Happy New Year

Have you noticed that besweet will crash every time when processing a file with "(" or possibility ")" in its title.

Gui ===> Batch dts (Sur dvd) ===> multiple to multiple

I presume it is the nature of the dos command and not to much you can do about it except avoid () in titles. Would " " work?

Funny how it goes .... about the same number of DTS fit on one DVD as did MP3 of the CD's in 95.

Peace

Since i got such a loud response from my last post here maybe i will ramble on some more. It appears to me that with Ambisonics 2ch to 5.1 the tricky thing is the LFE and its amplitude during the normalization process. I have a question.

Would it be possible to break the waves into 5.1 mono files and then normalize the 5 as they are dependent (equal amplitude increase) and the .1 (lfe) independent? This would for sure be the fix for the lfe channel and give the best result.

Peace

Edit typo

A quick (but dirty) solution would be to demux your 6-ch-wav twice (into different directories).
-> once without normalisation : just keep the LFE, and delete the other channels
-> once with normalisation : delete the LFE, and keep the 5 main channels

Again this only applies to the pure Ambisonic, not AmbioPhonic (Stereo Dipole, HRTF etc) stuff.

This should work fine!

The dirty would be more than twice as long to do. You would have to run all waves through both programs twice and could not use .bat file pass through in besweet.

The quick? i really don't see anything in the process you mention as being quick.

I guess i was kinda wondering if its possible to implement into besweet and if anyone else thinks it would be valuable switch.

Have you tried to use the "gain" VSZ inside bidule (you will need more than one, because it only has 2 pins in & out).

Then setting the main channels as they "sound" OK on the PC speakers, using a gain for the LFE you knoe is working from your experience.

Then runninh the bidule in offline mode, and BeSweeting w/o gain.

Sorry I cannot help more, as I don't use an LFE.

Cheers,
Andreas

Yes that is how i am currently controlling the lfe channel but gain does not equal normalization.
