  • Forum Post: PurePath BiQuadFade question

    Bruce12833
    I am trying to use the BiQuadFade component (through SPI). When I set the Enable Transfer flag address (0x0c on my process flow) I am expecting to see this address go to zero after the transfer is complete. What I see is this address staying at 0x80. Is there some setup I am missing? Thanks.

  • Forum Post: PurePath Mono Mux question

    Bruce12833
    I am having some trouble using the Mono Mux component. PurePath publishes the I2C Interface as Page 44, register 8. When I look at the generated driver I see it is using a 24 bit number to select the input ( address 10 holds the selection). The Mux. Help says that this interface is a 32 bit number...

  • Forum Post: PurePath support for LEC on AIC3254 miniDSP

    Wayne Duquaine
    The AIC3254 miniDSP currently has support for Acoutic Echo Cancellation (AEC) in PurePath GDE. Any plans for providing Line Echo Cancellation (LEC) as well ? It would be very handy for Telco based applications.

    Mikael Bohman
    In the premade examples from TI, the AEC demo uses I2S as the input/output for audio. In an embedded design, it's intresting to use the A/D & D/A of the CODEC for input/output combined with the AEC. Is it possible to instead use analog Input/Outputs under the AEC framework? And if so, which...
