I ordered a TAS3208-LC EVM and after some initial hickups and schematic studying I got the EVM up and running.
I also implemented some IIR filters and delay lines using the GUI.
Most work actually was to get the coefficients out of Matlab into a textfile format that PurePath Studio understands
(suggestion to allow an Excel format input or so?)
My plan is to implement a 3-way active cross over for an active speaker system with variable highpass in the bass section dependent on the volume.
There are some great features built in like the RMS measurement.
Another feature I want to build in is a safety feature to allow immediate muting of my audio, controlled with GPIO pins on the TAS3208.
Does the GUI supports the GPIO pins and if not, how can I signal to the DSP that an GPIO pin is activated, muting the audio??
