filter and echo program

Started by cherifanissa May 24, 2003
Iam working with a KIT DSP (TEXAS INSTRUMENTS)on DSK C5402.
I am searching an echo program done with functions "codec_read"
and "codec_write" and also a filter program (low, high and band pass
filter )including in the codec program.
Codec parameters used:
sampling rate 16kHz
ADC mode 15-bits
DAC mode 15-bits
Analog input gain :6dB
Analog output gain : -6dB
Thanks a lot!
