Fixed Audio Processing Flow (Program 5)
The PCM514x family implements signal processing capabilities and interpolation filtering via processing blocks.
These fixed processing blocks give users the choice of how much and what type of signal processing they may
use and which interpolation filter is applied.
These fixed processing blocks give users the choice of how much and what type of signal processing they may
use and which interpolation filter is applied.
The signal processing blocks available are:
•
•
Biquad filters
•
Multiband DRC
•
Mono mixer
•
Stereo mixer
•
Master volume
The addresses of the coefficients are fixed when selecting the fixed processing flow, however, if these
components are used in the RAM source mode (Program 31) the registers for coefficients will change. Users can
find more details in Purepath Studio.
