speech signal process tools

You will only need to use these menus if you have purchased ETSM (an
optional waves+ add-on product for time scale modified playback) or if
you are using a third party DSP board (Ariel DSP 32C, LSI C30, or
Townshend DATLink) for playback and/or recording.  If you are using
native hardware for playback and recording, you will not need to use
these menus.  

Playback on native hardware should work automatically without your
having to make any changes to the xwaves configuration.  The internal
play code in xwaves works automatically on all architectures except
for DEC Alpha, and on DEC Alpha we have set the .wave_pro file up
properly to use the external play program decplay.  See Chapter "Using
audio" of the waves+ Manual for more details on controlling playback.

To record files using native hardware, use EnSig's Record tool, or the
ESPS recording program for your architecture.  In general we recommend
that you record files using EnSig's Record tool, a graphical user
interface that allows you to record files on all architectures.  The
Record tool uses the native workstation hardware.


TIME SCALE MODIFICATION (ETSM PLAY)
===================================
Allows you to add TSM playback to the waveform menus and to add the
TSM toolbar creator to waveform menus.  When right moused, a drop down
menu is displayed from which you can make your selection.  Note that
you must have a license key for ETSM installed to use time scale
modification. 

PLAY (3rd PARTY PROGRAMS)
=========================
Allows you to set the third party DSP board to use for playback: Ariel
DSP 32C, LSI C30, or Townshend DATLink.  Note that Entropic no longer 
supports external DSP boards;  you must contact the vendor for drivers
or updated play programs for these boards.  Note also that these play
programs will only work on the files they supported in the past, and
will not work on certain new file types that ESPS/waves+ now supports,
such as Esignal and PC-WAV files.  

When right moused a drop down menu is displayed from which you may
select your play program. Effectively the xwaves symbol play_prog is
set. Subsequent calls to play functions will use this program.

RECORD (3rd PARTY PROGRAMS)
===========================
Allows you to set the third party DSP board to use for recording:
Ariel DSP 32C, LSI C30, or Townshend DATLink.   Note that Entropic no
longer supports external DSP boards;  you must contact the vendor for
drivers or updated recording programs for these boards.

When right moused, a drop down menu is displayed from which you can
select your record program.  Selections are provided for both 
mono- and stereo-recording on the different boards and with various 
sample rates.  After you select a recording program from the xwaves
Record panel, a button panel pops up. This panel contains two buttons:
one to start recording and one to stop recording.  After you have
stopped recording, the recorded signal is displayed in xwaves.
