Audition does not support 24000Hz?

[guywhitmore]

Hi, I'm working on a game project that needs some of the audio to be saved as 24000Hz wave files. 

I see 22050 and 32000Hz as options but not 24000Hz.  Is there a reason?  Seems like half of the 48000Hz standard would be easy to support.

Thanks much,

You can manually type in a Sample Rate when converting, and it will appear as a new option in the dropdown list.

Supported but an unusual choice for a game.  That's an unusual sample rate and far from a standard.

yes.  yes it is.  it is an unusual project, to be sure.  However, when 48kHz is the primary sample rate, 24kHz is more logical than 22050Hz for the 2ndary sounds.

I get that, but how is this going to play through physical devices that don't support that rate natively? Your only hope is a software resample to a supported rate, I would have thought - which hasn't really saved you very much (if anything...)

The DAC (converter) default sample rate output is 48kHz.  It's the Xbox console.  The game audio engine can take pretty much any sample rate and upmix to 48kHz on the output bus.  A lower sample rate is mainly to save disk/RAM space, so 24kHz halves the size of any content.  upsampling from 24kHz to 48Khz uses negligible CPU (ogg/mp3 etc. is very CPU intensive by contrast)
