Long story short, I need to split a 6.07 GB 24/96 .wav file into several
smaller files (less than 2GB) so that I can edit them in Cubase SX. My
OS is Win2k. I have tried using the DOS program AudioHack, but the files
it outputs cause an unsupported format error message (even if I change
the extension to .raw). Also tried chopping up the region in Cubase, but
it won't read past 2 GB from the beginning of the .wav. Can anyone
suggest a utility or method to recover the remainder of the file? Thanks!

Sounds like we need a "stream editor" for .wav files... something which
understands how to simply break it up into chunks with appropriate
headers. Should be trivial to write, actually, since .wavs are (I
believe) a relatively simple file format...

Seems like a program like Audition/CE which supports raw
formats, is what you need to deal with the files coming out
of AudioHack.

Raw format is basically .wav file format with no headers. It
looks like Audiohack is literally chopping the files, which
results in a file with no headers.

There's a set of command line utilities that allow you to extract sections
of .wav files. I know they were written for the SGI and they show up on
Cook's web list of SGI audio utilities, but I am sure they have been ported
to Linux and OSX these days as well.

wav files can be all kinds of things, but the most common format consists
of alternating 16-bit or 32-bit words containing right and left samples,
and a fixed 56-bit header saying what's inside. In fact, all you need to
do is strip the header off, send it to the output, count off to the starting
position, start copying the number of samples desired and copying them to
the output, then ending. You could even do this with sed!

If your HDD is formatted as FAT32 you may be having trouble with a 2GB
file-size limit inherent within that file system. If this is the case you
could always try converting the HDD to NTFS which doesn't have this problem
but BACK UP your stuff first! If not then I'd just download demo's of audio
editors until you find one that will allow you to open the file, zoom right
out and chop it up. File splitter apps will generally just chop the file
without worrying about headers as the usual purpose is only to chop it up so
it can be reassembled later. Obviously without the header info your chopped
up wav files will be largely useless.

Good luck

For your information- I just tried generating a 6 giga file with
audition and it crashed brutally. Looks like the limit it can handle is
4 giga.

A WAV file can only be 4 gig in size - check out the WAV file spec.

NTFS is definately not HPFS nor was a majority of it taken
from HPFS. . Yes, the team that designed NTFS knew HPFS
internals, but they also knew about the internals of a lot
of other file systems including the VMS file system.

Dave Cutler, the chief architect of NT, was hired away from
DEC, where he was the chief architect of VMS.

Prior to the initial introduction of NT 3.1 I used to be a
VMS systems manager as well as a VM/CMS internals system
programmer,. I also was quite familiar with IBM OS and MVS
internals.

NT borrows more than a few ideas from all of them, and also
Unix.

Okay, I may be wrong there. I was under the impression that NTFS was forked
from HPFS. I'm pretty certain that in the beginning both OS/2 and NT could
use each other's filesystems before the relationship soured, but of course
that doesn't mean they both used the same FS.

In some sense, just not "largely taken"

I'm pretty certain that

NT pre-exists Win95!

NT 3.1 was first delivered to the public a few months after
Win 3.1, as I recall.

The original plan was for Win95 to be based on a NT kernal,
but the DOS program compatibility issues were too much.

2K looks like 98, but under the hood it's an *entirely* different animal.

There were two distinct OS paths, the business stuff (NT) and the consumer
stuff (9x). NT4 became 2K with a major rework, including the new "95"
interface and a lot, lot more. It was called NT5 before it was released. XP
then came directly from 2K in 2001.

95 begat 98, which became SE when they fixed a pile of bugs, which begat ME.
ME seemed to be a public beta test of a bunch of eventual XP features. Major
POS system that I wouldn't wish on anyone. The 9x line didn't lead to
anything else, the line dead-ended at ME.

lol, nope. It was recorded in Cubase SX 2.something.....it looked like
it was writing audio right up until I stopped it at about 3 hours. I'm
pretty sure the data is still there, it's just a matter of splitting the
file up.

If I use AudioHack to write new .wavs without any header info, will I
have to spend all day to piece it back together, or just chop off the
headers at the beginning and end? (ie. there aren't several headers in
chunks located all over the place are there?) I don't care if I lose a
few samples here and there, or even a few seconds (depending on what
spot it's at). Thanks!

Hi Johnny,

You need a sequential editor in order to handle something this big and,
again, success cannot possibly be guaranteed.
If it was a normal 44.1/16 audio file you could use one of plenty free
utilities available on the web that could convert your file into RAW
PCM format (like wav2raw). I haven't tried those with 24/96, and I've
never compared the header differences for those files.
FIRST, back your file up. It should fit onto a dual-layer DVD.
Second, use a binary file splitter utility and split your file into
smaller chunks. There are hundreds of utilities that can do this,
SPLITS is one of them (just google: binary split files).
Open the first file of the produced sequence with a binary editor and
remove the header (you can check by yourself easily: create a very
short 2496 wave file, save it and then convert it to raw and save the
raw file as well; then open both files in the editor window and check
out the difference).
Try importing the chunks as raw files in a wave-editor and see if this
is working out for you... since you mentioned that it won't be a
catastrophe if a few seconds were lost!

Good luck,

Windows ME should really have its own special classification because MS

It's dead anyhow.

I know NT had many versions, but NT reached critical mass, so to speak,
around NT 3.51. It became alot more popular with 4.0. So when people
refer to Windows NT, chances are they're talking about NT 4.0

OK, I've reproduced the problem in Cubasis on Win2K. You can creat a .wav
file as large as you like; however, a .wav file contains a 32-bit header
containing the length of the data.

What you get in the header is the low-order 32 bits of the data length; so
for your 6GB file, you get the data-length minus 4GB, which is where the 2GB
comes from.

I think I can help you recover the data if you still have the problem; let
me know if you still need help, and I'll get onto it tomorrow evening.

Just for the record, and for anybody else who might have this problem in
the future, I solved the issue by splitting up the .wav with AudioHack,
a command line based program and then repairing the output files in
Samplitude. The whole process went something like this:

1) Put the oversized .wav file (example: audio.wav) in the same folder
as AudioHack
2) Run AudioHack and it will ask for a input filename, so type "audio.wav"
3) Then it will ask for the output #1 filename, type "audio1.wav"
4) Then it will ask for output #2 which is the remaining portion of the
..wav "audio2.wav"
5) Open audio1.wav in Samplitude, it will give you an error message
saying it's damaged. Tell it to open anyway and specify the type of .wav
file it is, in my case 24/96k/stereo.
6) Make sure everything sounds right and export it to "Audio_1.wav"
7) If audio2.wav is less than 2gb, open it in Samplitude and follow the
same steps, if it's larger (as it was my case) start over from step 2,
changing the filenames of course

Also, if you want to run AudioHack with the /H or /N switches, you'll
have to open the windows command prompt, cd to the folder that audiohack
is in, and type "audiohack /n" or "audiohack /h" ....for me it worked
just fine without doing this

Anyway, I stayed up until 4am burning the 24 and 16-bit masters onto DVD
and had to catch a plane at 6:30am ....whew! Thanks a TON to everyone
who helped!! You really saved my arse!
