How to decrease Audio Slice sample frequency?

Post by simmartin »

Hello,I'm using Slicekit + Audio Slice. Using the provided example (modified to perform a simple loopback on each channel - out0 = in0, out1 = in1, etc..) all works well if I define the sample frequency to 48000 or 41000. I have problems if I decrease that parameter to, say 24000... but from what is documented and CODEC specs it should work as well. For example, starting form the "Loudness Slicekit Audio" example, I changed the define "SAMP_FREQ" (inside the file app_global.h) from 48000 to 24000 and tested also 22050, but no audio is provided on output. The same code with 44100 or 48000 works really well... I need some help to decrease sample frequency (if possible)!

Ok, it is a hardware limitation... decreasing the PLL oscillator helps :D
