SPARCstation Sound Tools
Alpha Distribution of 10jan90
Previous distribution 20nov89
This package contains some simple sound tools for the SPARCstation-1.
The SPARCstation can record and playback telephone-quality sound using
the Am79C30A audio chip from AMD. Telephone-quality means 8192 samples
per second and eight bits per sample, so don't expect Hi-Fi. The chip
has a few interesting abilities other than record and playback, such as
tone generation. For full details call AMD's "literature center" at
(408)749-2264 and ask for the spec, publication #09893.
In addition to the tools that directly manipulate the sound chip, this
package includes some simple filters for manipulating sound files.
Feedback is welcome; send bug reports, enhancements, checks, money
orders, etc. to the addresses below. Be sure to mention what version
you have when sending bug reports!
