Audio-Tone
==========

Audio-Tone.demo.app, Pure Tone Generator module was written for
real-time synthesis of the sinusoidal (pure tone) signal.  Signals are
generated in real time and do not require the DSP processor (which is
not available in some NeXTSTEP computers).Therefore this software will
run on all NeXTSTEP computers equipped with D/A converters.  Signal is
generated in RAM and for this reason no hard disk space is required
for operation of the Audio-Tone.demo.app program.  This program works
very nicely with Digital  Oscilloscope  and Spectrum Analyzer (both
applications come with NeXT) and any recording / editing software.
Playback and recording/ analysis of the signal could be done
simultaneously since DSP chip is not used and main processor is used
only 2->3% during signal production.
