buffer ~ sample types and bit rates.

March 21, 2012 | 8:55 pm

sorry if this is a dumb question, but i am wondering if using buffers at lower bit rate of sample types/rtes will save on cpu?

i am messing around making a looper in maxforlive, and i have 4 versions of the same subpatch using buffer, record and groove objects and my cpu is in the 30s, yet when i have max open for editing, the cpu in ableton drops to 3.

cheers.

of course will it save CPU, but to lower the buffers samplingrate will require you to put the whole runtime
at a lower signal rate. if you have a semi professional audio interface, 22 khz for example wont be possible.

what you could do is putting the buffer into a poly and use downsampling via poly patcher.

however, both methods will require you to downsample the files to be imported prior to working with them in max.

not sure if it is worth the hassle? there are better tasks where one can save CPU…

p.s. buffer~/play~/dac~ uses less than 0.5% on my 11 years old 900 MHz PPC G4 computer …

thanks for the tip. are you running in max stand alone? i am building in maxforlive.
