-
- D/A converters have no direct connection from the DSP chip, in the
- way DSP program can access the D/A hardware.
- It is the sounddriver that keeps the D/A sample stream filled up.
-
- It is possible to set up DMA streams out of DSP and then to the D/A.
- A very good example code is in JeanLarouche collection of examples
- particularly DigEars example. Which gets sound data from DigitalEars
- and play it through D/A.
-
- Get JeanLarouche.tar.Z file from ccrma-ftp.stanford.edu in pub dir.
