    Gonzalo R.
    Hi, I'm following "AIC3254 Acoustic Echo Cancellation" application note from PurePath. I've tested AEC algorithm showed in page 7 of this document and everything run ok. In this case the far end input and output are connected via the I2S port (USB), and the near end input and output...

  • Forum Post: PurePath - Interprocessor component

    Onur Arkut
    My question is about the operation of interprocessors, about which I feel I'm missing something important. In some example AEC process flows, for example AIC3254_AEC_12LE, the output 1 of DSP_D_DSP_A_AEC_LE is directly linked to the input 1 of DSP_A_DSP_D_AEC_LE, and then from its output to AEC_12LE...

    Hi Paul, We do have 3rd party SW running on TI DSPs, which probably can help you. Building hands-free applications also is a challenge when it comes to acoustic design, we can help you out with this as well. Check out www.limesaudio.com for more info. Regards Fred
