Most of the Macintosh applications that record and play back 8-bit internal
Macintosh digitized sound have their limits set by the amount of RAM in the
machine. There are some high-end, higher cost, 16-bit, CD-quality sound
solutions available. One of these is Sound Tools from Digidesign. This
solution includes a NuBus card, external hardware, and software for the
Macintosh II.
