Hello everyone,

     We use DVRRDK3.0 in DM8168 board, for audio,we need the function of  echo cancellation,I have  installed Texas Instruments Acoustic Echo Removal (AER) software,both for ARM and DSP,but I don't kown how to intergrate it to  our DVRRDK usecase.Besides,this AER software  can't  to process the audio data with 44.1khz samplerate,I want to  know,could I  modify the source code in order to support the 44.1kHZ samplerate,and in this software I   haven't found the source code,so if I can modify it ,I want to know where is the soure code is?

   If this algorithm is supported like a lib,and I can't modify it ,I want to know if I use our algorithm to process the echo,and want to execute in DSP,what framework can we use? Between RPE and IPC,what is suitable for deliver audio data between ARM and DSP?

Thanks for any reply!!!
