Hi Kurt,

I've been playing around with beta 9 today and must congratulate you on designing "yet another" outstanding product


Many thanks mate...

Wow...

I've just used BeLight to encode an 6Ch AC3 audio stream to an 6Ch AACplus v2 audio stream. And muxed this stream to an 720x576 anamorphic MPEG-4 AVC video stream using YAMB and got myself a lovely looking and sounding back-up of Terminator 3 (with chapters of-course)


Okay.... I have made the following observation....

If I encode this 6Ch AC3 speaker mapping test file to an 16 Bits 5.1 Wave .WAV file - the mapping is perfect

However, if I re-encode the 16 Bits 5.1 Wave .WAV file back to an 6Ch AC3 file, the mapping is incorrect

Am I doing something wrong?

Just to confirm: Re-encoding the afore mentioned 6Ch AC3 speaker mapping test file to another 6Ch AC3 file, creates perfectly mapped results
EDIT: And so does re-encoding the 16 Bits 5.1 Wave .WAV file to an 6Ch AAC file.

Cheers

@ what rate did you encode the file ?

on a previous note i was using nero aac to make the file i said was comming out as mono - i will try with aacplus and see what happens - i have updated nero itself but have the old dlls in besweets folder so i guessing that is ok, and what bitrate is (and i wont say best as i know i will get beat up for it) advisable for a backup or doesnt it really matter.

all these new formats im trying to learn i should have just stayed with dvdrs ;D

With AACplus sounding as good as it does.... I can't see uch point in bothering with Nero... LOL

could have just said default 96kbps

im trying out all the audio codecs to see which one i like, as i have done with the video codecs

suppose i could do the MS thing and stick with the one audio and one video codec

but i think the linux route is better

ac3enc.dll, and others ac3 free encoders (ffmpeg, ...), need a wav6chan reordered to: FL_C_FR_SL_SR_LFE (ac3-order)
instead the standard wav order: FL_FR_C_LFE_SL_SR (wav-order)

When you make ac3 -> wav6, BeSweet do ac3-order -> wav-order.

When you make ac3 -> ac3, BeSweet don't reorder.

When you make wav6 -> aac, Dimzon's plugin do wav-order -> aac-order.

You can use WaveWizard with the channelmapping setting "ac3 order for SoftEncode or ac3enc" to make a wav6 (ac3-order).
Or you can split the wav6 in 6 mono wav and use a mux file (ac3-order) with BeSweet.

Thanks for your explanation tebasuna51

I'm still at a loss to understand why when you have a correctly mapped 6Ch WAV source, would anybody want generate an incorrectly mapped 6Ch AC3 file. Surely... it's just asking for trouble!

As you guys can probably tell I'm not very upto speed about how all this mapping works and the reasons behind it. So may I ask, who along the decoding-to-re-encoding chain gets to decided how an 6Ch WAV source to 6Ch AC3 encode is mapped?

Hope that make sense!

But this is not very efficient if you compare the results with some other lossless formats (wavpack, monkey's, flac, etc...)
Have you considered adding support for FLAC?

Sounds like a plan...

Now I've got the hang of BeLight (goodbye to HeadAC3he and Foobar2000)... I'm going to recommend it to all my fellow Zensonic Z500 users tomorrow!

I think I have all the latest .dll files installed now... but I'm not sure about the Vorbis .dll's



Any help would be much appreciated

@Kurtnoise13

little update on the strange winamp showing mono issue - i think its just winamp being a tit, i have done encodes with all encoders in belight and ran them thru diff players - ffdshow (as do other players) reports that the input is 48000hz,6 channels sbr aac

and output is
48000hz,6 channels 16-bit integer

with output speakers as l,r,c,lfe,sl,sr

just strange winamp says mono

That's is Winamp bug, not BeLight.

btw 6 channels are 6 mono channels so winamp shows pseudo correct info, and when you open file info in winamp you see right information.
