I have a Panasonic DV recorder that also records sounds in a VM1 raw format - I've got some recordings of a steam traction engine I want to extract.
The panasonic web site is less than helpful.
Is there any way to find out what parameters I need to use to open one of these files in Cooledit? (I have version 1.7 I think, I'm away from my home PC at the moment)
I've tried most of the bit size/frequency options available so far - or do I need version 2.x ???
Ta,
Paul

I have no idea what constitutes the VM1 format- it may well be proprietary - but wouldn't it be quicker and easier to make a quick excursion into the analogue domain and re-record in PCM format? In view of the source material, the minimal quality hit is going to make much difference.
Latest version of CEP (before v.2x) was 1.2a. That's the one you really should have, even if you don't want to go to v2

Thanks for replying, yes 1.2a is the one I have.
VM1 is listed as one of the formats that Cooledit will open, but it is a raw data file, no format info included so you need to enter the parameters to make it work.
Unfortunately, it looks like I'll just have to re-record it as a low quality mpeg video onto the SD card and extract the sound from that.
(or onto tape and get a DV input into my PC)

Fine - that clears that little matter up :)

I couldn't find any reference to VM1 in my help files. Neither could I find any information on the net (although I didn't spend a lot of time on that exercise). If you can import it as raw data and you know nothing about its structure, you can spend a lot of time trying all the variables out.

I'm not familiar with this bit of kit, but I was assuming that it would playback a recording and provide an (analogue) audio output. That being the case, I'd just hook that straight into the computer and re-digitise it in a format we do all understand.

DV is going to have one of two digital sound options:
4 channels of 12bit/32Khz -- not likely
2 channels of 16bit/48Khz -- quite likely.
You could try that and see what you get. Also, I don't know whether Motorola or Intel byte order is correct, so that's a 50/50 chance and something worth trying twice for!

I'd try the above first. Then, if it still doesn't fly (and IMO even if it does), I'd get the firewire card. At $20, they're a steal these days, and once on your PC in DV format, any number of progs (some freeware) will extract PCM WAV from them. Plus, PC vid editing is just COOL!
