Testing custom audio input routines on an Amiga 1200 with a standard parallel-port sampler.

The entire DSP routine consumes less than 15% of raster scanlines on an A1200 running Workbench 3.1.
By setting up Paula's audio DMA to double-buffer incoming 8-bit samples, the 68020 has plenty of cycles left for the Costas loop.

Long live the Amiga. Try doing real-time subcarrier demodulation on a 386 running Windows 3.1 without dropping frames!

Please make sure it's compatible with Kickstart 1.3 for those of us who haven't upgraded our A500s to 3.1 yet.

Top-posters will be placed in my ~/.killfile without notice.
