Editing a 6ch wav with Audacity

[trenz]

I currently have a 6ch wav with about 2 min of silence at the beginning. How would I use Audacity to edit this? When I open the wav it says opening WAVEX file and the 6ch are listed as left, right and 4 mono's. If I check the properties by right clicking the file then properties, then summary, it says sample size 16 bit but Audacity says 32 bit float. When I delete that 2 min and export as a wav it is saved as stereo WAV. I am doing something wrong. What is the difference between WAVEX and WAV. How do I keep it a 6ch wav after I delete that 2 min.

I thought I might try to use belight to separate it into 6 mono wav's, edit them individually, then mux back together but I get this error message in belight 21 (also tried v.22)
Error 58: Error : Unknown Input-File Format

Any ideas or suggestions of a program that can edit this wav

It is the song Psycho Killer ripped from the Talking Heads concert dvd Stop Making Sense. I plan to make a dvd-a disc and would really like to get this silence off this song.

Thanks

here are the properties of the file.

I´ll guess your 58 error on besweet has something to do with the settings of bidule, PLZ check your preferences (see picture!)

AFAIK Audacity can't save 6ch wav. If you have Nero 7 you can use Nero WaveEditor, but the output is WAVEX also.

What is the difference between WAVEX and WAV.
Only the wav header, WAVEX is more complex and not supported for old audio soft.

BeSweet (BeLight) don't support WAVEX.

How do I keep it a 6ch wav after I delete that 2 min.
If you only need delete first 2 min. you can rename your wav6ch to:
yournameDELAY -120000.wav
and use WaveWizard (http://needfulthings.c-f-h.com/tools/) with this settings checked:
- Menu Edit -> Preferences -> Process Delay. Output Format: Wave PCM.

Then you have a standard wav (not WAVEX) with first 120000 ms deleted.

Awesome, worked perfectly. Do you have a suggestion for removing silence from the middle or end of a 6ch wav? I don't currently have one like this but since I am gathering all this knowledge I would like to know if this is possible.

Thanks

Do you have a suggestion for removing silence from the middle or end of a 6ch wav?
You can use WaveWizard to remove end silence in two pass:
1) yournameDELAY 120000.wav
- Menu Edit -> Preferences -> Process Delay. Maintain Length.
Inserted 2 min of silence, the last 2 min. deleted.
2) yournameDELAY -120000.wav
- Menu Edit -> Preferences -> Process Delay.
The inserted 2 min. are deleted.

Or you can use WaveWizard to convert WAVEX in wav PCM an after use BeSweet (or BeSplit to cut the file in many segments). At last, use BeSweet to join the segments.

But you can do any job in only one pass using BeHappy/BePipe in AviSynth style. You need create a .avs file with:
bassAudioSource("D:\YourPath\YourName.wav")
#
AudioDubEx(BlankClip(length=Int(1000*AudioLengthF(last)/Audiorate(last)), width=32, height=32, pixel_type="RGB24", fps=1000), last)
[b]trim(0,119999) + trim(240000,359999)
# [BeHappy: Kill video]
AudioDubEx(Tone(), last)
This select the first 2 min, delete 2 min and select the next 2 min.
