multi-channel wave editor

[monohouse]

that can open 7.1 .wav and save 7.1 wav, I've tried cool edit pro 2.1 but it reads the file wil each channel separately, and when saves, only saves separately

does anyone know a good wave editor for this kind of wave files ?

[shon3i]

I cool edit in multitrack view you have Multichannel/Surround Encoder on View menu.

I think most usefull multichannel editor is Nero WaveEditor, support biggest multichannel input and output types.

[monohouse]

found it thanks, but that seems to only support up to 6 channels

[shon3i]

Then use Nero Wave Editor.

nero only opens the first 30 minutes of the multichannel track, that does not sound like a professional approach to mastering multichannel audio, are you sure there are no professional methods ? (ones which opens the whole file ?)

Do you have full licensed version of Nero? If yes then please describe problem in more details and it will be fixed.

hmmm, seems like Sound Forge can handle this, Multi-Channel in one window and not separated view like Cool Edit/Audition.
only 30 minutes? is your file larger than 4GB? if yes, I got this problem too, most programs can't handle WAV files larger than 4GB.
only program I found is EAC3TO...

And AviSynth based like BeHappy, MeGUI...

I stumbled across this one the other day, does multichannel waves and it's free.

oh thank you, I don't know because I never tried to use AviSynth to open a WAV larget than 4gigs...hmmm, maybe very useful for some cases

You need NicAudio.dll v2.01 (http://www.codeplex.com/NicAudio) plugin (very common for audio: ac3, dts, mp2, mp3, lpcm, w64, ...) and use the RaWavSource() method to open wav, raw, wave_format_extensible, w64, rf64, ... without the 4GB limit.

6,326,292,548 bytes, 8 channels, 24-bit packed int, 48 khz

I tried to open it with wavosaur, but it says an unknown error occured while accessing E:\audio.wav it seems that this program doesn't really do it, I also tried to do "import" but it saysunable to load file

is there an alternative approach ? such as for example to split the channels like in cooledit and manually edit them and then use a program that can join them correctly back into multichannel ?

[tebasuna51]

To split and join you can use WaveWizard.

[monohouse]

good, thanks, just one other thing, what is the correct order of channels for 7.1 ?

[tebasuna51]

The standard uncompressed wav file 7.1 must have this channel order:
FL-FR-FC-LF-BL-BR-SL-SR

[monohouse]

front left, front right, front center, low frequency, back left, back right, what is the rest ?

[setarip_old]

Surround Left, Surround Right...

[tebasuna51]

Surround Left, Surround Right...

Nope, Side Left and Side Right (is the MS names).

Surround is the name for 5.1 ac3 rear channels.
If a 5.1 ac3 channels need be converted to 7.1 the Surround channels must be distributed between Side and Back channels.

Edit: More or less
FrontC -> 0º
FrontR -> 30º
SideR -> 90º
SurroundR -> 120º
BackR -> 150º

@ monohouse
i think that S.Forge and Audition can open your 7.1 file.

@ tebasuna
cool explanations as always! :-)
