OSx 10.8.5, Max 6.1.3
I have not needed to reduce audio driver sampling rate below 44.1K but am looking into it for a costly MSP process.
using the Audio Status window or [adstatus sr] there are no options for globally reducing sampling rate below 44.1; I only get higher numbers in the umenu. I know that [poly~] and [degrade~] and other objects allow for this, but have I missed something that will set a lower overall sampling rate for MSP? Maybe it's Core Audio dumbness.... See Max documentation: http://cycling74.com/docs/max6/dynamic/c74_docs.html#mspaudioio
"You can set the audio sampling rate with the Sampling Rate pop-up menu. For full-range audio, the recommended sampling rate is 44.1 kHz. Using a lower rate will reduce the number of samples that MSP has to calculate, thus lightening your computer's burden, but it will also reduce the frequency range. If your computer is struggling at 44.1 kHz, you should TRY A LOWER RATE."
