TMS320C5535: Voice Pre-Processing: 8khz sampling

Part Number: TMS320C5535

Hi,

I am using Audio Pre-Processing exmaple code for C5535 EZDSP, connected to PCM 8 Mic CMB. I have configured and made changes in code to work for 6 MICs. 

The example runs at 16Khz sampling rate. I want to run it at 8Khz. I have made the changes in below lines ( changes 16000 to 8000):

BF_rt_bios/AudioCodec_DMA.c: status = AIC3254_init(16000, 16000, PLL_MHZ);
BF_rt_bios/AudioCodec_DMA.c: status = PCM186x_init(16000, PLL_MHZ);
BF_rt_bios/codec_pcm186x.c: if (sampRateRec==16000)

I have also changed the BF Co-eff using bfgui.exe.

Other than this any changes needs to done for the program to work?
