To put it in old time tape terms, with a mono source, no matter how you do it, your client will be getting good ol' two-track mono (or if you prefer, 1/2 track mono).
But you'd better tell him it's stereo  |

Thanks. And yes, frequency range defines the clarity as well. They go hand in hand. Who records direct to mp3 anyway for professional projects? If you record at 22 kHz, you will not have the same clarity you would if you record at 44.1 or 96kHz. There is a thing called upper and lower harmonics that can be captured and not even noticed until you hear a recording done at a high sample rate and a high bit depth (ie 24 bit). It just sounds better, cleaner...more accurate to real life audio. The bit depth or rate determines the amount of info/music/voice transferred per second. For voice only...not so evident....for music.....it is very evident on monitors that can produce accurate sound.

Random trivia:
Q: Why is CD audio recorded at 44100 hz?
A: Because it’s a mathematical link between Pal and NTSC video format, of course!
Q: Huh?
A: In the days of early digital, the way to get move the digital audio around was on videotape. And they could store the digital information on tape because:
NTSC - the American Standard
60 fields per second
x 245 usable lines of resolution
x 3 colors of RGB
--------------------
= 44100
PAL - The standard in Europe and Japan
50 fields per second
x 294 usable lines of resolution
x 3 colors of RGB
--------------------
= 44100
Isn't that fascinating? No? oh well.....

Japan is NTSC.
Picky I know, but I have a lot of catching up to do with my post count.
Actually, I used to have one of those old digital audio systems. It was my first 'portable' system. A Betamax deck with a technics A/D convertor. It was portable much in the same way as a bag of bricks.
Ah! The fond, nostalgic memories we treasure of our early days of audio.
An MCI 2" 24 track and the ritual heart stopping degaussing that I hated so much.
Chinagraph pencils, splicing blocks and razor blades.
Sound effects on single sized vinyl records that actually played at 33.3.
Three of us manually mixing a track on a 24 channel desk in the days before affordable automation.*
Storing tapes tail out to avoid print through.
OK, what was this thread about again?
Maiku
*This was at the end of a 48 hour recording marathon. During one of the mixing passes all three of us fell asleep at the board. We were woken by the flap-flap-flap of the tape after it had unspooled at the end.

My stereo rate is twice my mono rate. I also offer a discount for files using a 2kHz high-pass filter.  |

| THAT'S what I should do! Tell them my rates are more if I record in stereo!!! Glad to know I'm not the crazy one...not for this at least! But they were VERY indignant and insulted when I tried (Gently, I SWEAR) to explain why recording in mono was perfectly fine........... ugh. I give up. So now they will get their stereo recording...as long as they never come and actually LOOK at my studio. |

A 44,100 kHz STEREO file is basically just two 22,050 audio tracks - linked together into the same audio file. This is what your clients is asking for - two 22,050 tracks.

As far as I can tell a stereo file has to be two channels with each being 44.1. That's how the Red book standard for CD's lays it out. Also, if I save a stereo file as de-interleaved then I have two mono 44.1 files. Not two 22.05 files.
Melissa,
You might want to ask the client what they mean by stereo. A true stereo recording can only be achieved by using two mics to record two independant channels of audio. Splitting a mono signal into two channels cannot really be called stereo unless there is a difference between the two in some way - such as by adding phasing or reverb or some such. If they just want two channels of mono then they could just as easily do it themselves.
Next they'll be wanting a surround sound mix.

| Mike, I've found that trying to discuss technical issues with this particular client only antagonizes them...they have it in their head what they want, and believe what they want...and I--and the tooth fairy-- will oblige, if only in fantasy. |

He's probably related to our client who insisted his voice files must be recorded in stereo at 96kHz sample rate, but delivered at 48kHz.

Just out of curiosity, Melissa, what is the final media this will run, TV, Radio, DVD?
I agree with Doc. It is and can be done, but is usually done in post.
AA should give you options when you hit "new file" to place the signal in separate channels.
We'll figure this out.
