First off, I would like to say EoH you are awesome! I have been working around with KpeX's SAD5.1 and it is very nice it does a good job, yet it was lacking something. Your new Ambisonics method works great! Hats off to you :-)!!!
If you guys are wondering how to get 6 mono wavs, well it is quite simple to do using CDP Multichannel Toolkit. You can download it from there website here: http://www.cs.bath.ac.uk/~rwd/mctools.html or a direct link to the zip file here: http://www.cs.bath.ac.uk/~rwd/mctools.zip Now once you download it, you will be working with the command-line tool called "channelx". Since it is a command-line tool you will need to create a new batch file with the following in it: @ECHO OFF channelx -och.wav YOUR_6CH_WAV.wav 1 2 3 4 5 6 This will separate all the channels within a 6 channel wav file. You can also specify which channels to take out with this tool. This is definately a handy set of tools. Last edited by joshbm; 4th September 2003 at 21:34. |

I had these tools already since more than a year, but now they're a bit outdated..... You know, there's also a tool called wav2to6.exe..... does exactly the same :-) And the Besweet tools, Soft Encode also....there are more... As long as there's no alternative (except doing it in a soundeditor) to the OTA -g max command..... I'm more than happy with Besweet !!! But it's always good to look at other tools too ! So....thanks for the links ! kind regards, EoH |

Speaker Arrangement
Now looking at the pentagon layout in emigrator
speakers should proly be adjusted to match... Has anyone tried this different speaker layout? dunno if the wife would let me turn the room into a pentagon hahahahahah @plogue david Is the 6 seperate recorders a bug or a processor / resources problem?

You create 6 separate mono recorders and sync their start parameters toghether?
sadly this trick is not very sample accurate. the only trick i know is to press rec on the first one from series of linked recs and then start the audio processing (circle icon on top of the app) then do the inverse after. Even then all files might not have the same end point, idd need to check. What we tought about doing was a single module that saved multiple mono files OR a multichannel one, so all mono files would be synched. We might add this in a future version. Cheers |

@ davidv; Good to see you here. Bidule (despite beta) is indeed a great tool, and I would like to say 'Big Thanks' for it. If you / your team can implemnet an offline (render) mode, that would really rock :-)
@ EoH: Quote:
@ bitsnbytes: Good catch. Using only B-Pan & Emigrator (w/o B-Proc), you would have to re-arrange the speaker set-up, as there would be a SC (surround center, in your back so-to-speak). In order to avoid this, we used a 'trick': Rotating the sound-field by -36 degrees counter-clock-wise with B-Proc. Result is that you don't need a SC (surround center) speaker. I know it might sound a bit confusing. It might help if you just draw the speaker-setup from Emigrator on a piece of paper. Channel-1 is slightly turned counter-clock-wise (by -37 degrees). Channel-3 is the surround-center (at the end of the minux-X axis). Then, by literally turning the sound-field by -37 degress (counter-clock-wise), channel-1 becomes C, channel-2 becomes FL, cannel-3 becomes SL, etc. Regards, Andreas Last edited by kempfand; 4th September 2003 at 22:56. |

IF you use the HNM filter for the LFE there is a AmpOut slider Try .333 seems pretty mellow setting for the sub you can also set the sub to cut off at say 60hz so its not generating subwoofer at higher range you can see my HNM filter specs on another previous post

Hello David, Welcome,

in fact, judging by the waves created in this particular process, it seems to save something like 2 extra bits out of the linear 24bits/16bits, due to gain loss of something like 13db. Quote:
applying 10db amplification before the audio file recorder seems like a reasonable act. Quote:
anyway, i've noticed that the product wave includes a "PEAK" chunk, so that's good enough for me Cheers, Dg.

Thanks For The Gain!
just what I was missing... I added 3 gains
utilizing 5 slots ... NOT using the 6th one for LFE as the HNM filter adds OutAmp ...Gain I set it to +10db much better

Playing around with Emigrator.
Used rig layout Oct2 with speaker mappings 1 - C 2 - FL 3 - FL 4 - LS 5 - LS and RS 6 - RS 7 - FR 8 - FR Just connect them to the right channels on the Recorder Out. Very good results as more info per channel. In DTS sounds great. Also I am fortunate enouth to have an amp that allows ES on any 5.1 sound, so when in 6.1 mode it works great as the 5 speaker would be the Center surround posistion. Now only if we could get a 6.1 encoding program - either AC3 or DTS Am working on the 3D rigs at the moment. |

since i now work in floating-point, i don't set a pregain value in the Bidule graph, i just add "-ota( -g max )" to the commandline from the BeSweet FAQ. note that a spike will prevent BeSweet from normalizing, that's why you might wanna add a "-split( -start 1 )" suffix.

@ DSPguru: Can't wait to get home in 10 hrs to use the new new BeSweet v1.5b21. Great job
Regarding the 1-2 sec spike (which someone else too described earlier): Try starting the play for 2-3 secs, stop it, move the slider back to the start, and play again. This has avoided the spike for me when I had it. Andreas |

the spike at the beginning cannot be avoided, since it's actually data - not samples, and in fact, this is useful data : it's the peak value of all channels.

/me wonder, perhaps there's a vst plugin for shell execute ?
the idea is to write the BeSweet commandline in this kind of plugin, and link its trigger with the end of the recorder. this way, we'll have a fully automated process. (stereo to multichannelwave,multichannelwave to dts) David ?

don't expect it in the near future..
anyway, how about updating your guide to use v1.5b21 with -ota( -g peak ) instead of v1.4 with -ota( -g max ) ?

you're right. no problem, a fixed one !!
all you need to configure in this plugin : 1. BeSweet.exe Path 2. Surcode.exe Path 3. Input FileName (the same one you write with the recorder) 4. Temp Directory for mono wave files 5. Output filename and a "start" button, to be linked with the "stop" button of the recorder. it will generate the commandline by itself. if you could attach here a zip file with a sketch source-code, i'll do the rest.. forgive me, but i don't have the time to read the VST specs..
