My band is going to be tracking at a really nice Pro Tools based studio pretty soon. I've asked the engineer if I could have the raw tracks to mess with on my home studio which consists of an analog board and an HD24XR. I have some DAW capabilities as well. The files he'll be providing are what he called "broadcast wavs." He emailed me a very short one to mess with. When I check the properties they are:

Bit Rate: 2304kbps
Audio Sample size: 24bit
Channels: 1(mono)
Audio Sample Rate: 96kHz
Audio Format: PCM

If I want to use these files on my HD24, what do I need to convert them to to do it. I'll probably want to convert them to 48kHz so I can have all 24 tracks, but does anything else need converting?

Thanks.
 
Transferring via fireport allows for AIFF or WAVs -- not sure if broadcast WAVs will work (never tried!)
 
On the off chance that somebody else has a similar question and stumbles across this thread, I wanted to post some info I found on the web.

Basically a broadcast wav is a 96/24 (or better) wav file that has some certain additional information imbedded into it. This additional information can include such things as author, copyright information, etc.

They can be converted for use on the HD24 through a number of programs including the one I've recently found r8brain. I also suppose a broadcast wav could be 88.2/24 which would make for cleaner conversion to 44.1.

Anyway, when we track in a few more weeks we're going to ask for 88.2/24 wav files and go from there.

Hope this helps anybody unfortunate enough to stumble upon this thread later...
 
i was under the impression that a "broadcast wav" could be even of any sample and word size, but that the differnce was that it did carry extra information about the file itself. R8brain really does not have anything to do with "broadcast wav" in specific. It merely is a handy standalone program that converts sample rates, and maybe even word lengths.

You are kidding right? Sample rate conversion isn't any easier or harder just because the original sample rate is twice the desired sample rate. GET THAT THROUGH YOUR BRAIN EVERYBODY!!!

Wow! As I've researched this topic I've read this kind of statement almost exactly as many times as I've read "if you're goint to convert down to 44.1, you're WAY better off starting at 88.2!" Heck, on this very board I've read posts by folks that swear they can hear a difference...

xstatic - I'd say you're right. I'm guessing though anybody who feels the need to use broadcast wavs, isn't going to go with 44.1 or 48... again, the whole thing started when this engineer we're going to record with started throwing the term around.

I think the success I had with r8brain could have been a fluke since that's also about the same time I realized that my "real" version of cakewalk home studio 2 (not the cheapy music creator I had been using) could make projects at 96/24... But for whatever reason, my HD24XR didn't like the sample the studio provided me with.

Thanks again everybody for your help!

There isn't anything wrong with R8brain at all. I was just trying to make it a point that R8brain is not a program for "broadcast wavs" but is a converter. it's stand alnoe as well which is very handy. No paging through menu's etc....

As far as the whole sample rate thing goes.... I think my computer is pretty darned good at math. It seems like it can effortlessly do divisions and multiplications to thousands of decimal places. I am sure it converts just fine from either 88 or 96 k down to 44.1. Math or no math I have a feeling that 96k to 44 still sounds better. Logically speaking 96 k has 11% more resolution than 88k. but, personally, I track everything at 24/44:D
 
xstatic - LOL I bet my computer can do some pretty mean division too :) So I guess it doesn't actually matter what we track at at the "real" studio, I can get it on my HD24XR in a number of ways.

It is funny how the 88.2-44.1 vs 96-44.1 topic seems to get as much discussion here as the J-Bass vs. P-Bass topic gets on the Fender board....
 
Why not just take the Alesis right into the studio with you and transfer it there:D
 
Not a bad idea, and one I'd considered, but at $1000/day I don't really want to spend too much of the label's time/money on my side project. I got a firewire drive as the engineer suggested and I'll end up with all the tracks on that. Then it's off to transfer land...
