APRL Change Log

This is the page that keeps track of the changes made to APRL. This is useful to know, since there are several people working on the project.

1995aug07 dpwe
Added "obj cget -opt" syntax to retrieve just the value of an option to all the tk and tk-like objects. Seems to be part of the standard for tk4.0
1995may20 dpwe
Synchronized my local changes with the main source tree and updated the ftp-able source tree and precompiled binary. Now will only run/compile with tcl7.4 / tk4.0.
1995may02 dpwe
* Added 'close' command to soundfsink. Really, it was useless without. * Added special-case optimized versions for filter:run running the common bpf and hpf/lpf structures. Something like 4-6x faster than general purpose routine.
1995may01 dpwe
* Updated for tcl7.4b3/tk4.0b3 * Added -linewidth option to wavesink * Implemented highpass filter.
1995mar14 dpwe
Made some mods/fixes to tkTimeline.cc and tkWaveSink.cc; addded "oscope.tcl" time waveform oscilloscope script (for Justine).
1995mar03 dpwe
Added -scale (multiplicative scale constant) to audiosrc, audiosink, soundfsrc, soundfsink, randsrc. Commands page updated.
1995feb27 dpwe
Added independent output sample rate to pitch tracker, added percent-substitutions in scheduler callback command string, gave that string a reasonable default. New tgz source tree in ~ftp/pub/Code/aprl has GNU readline option turned on, since "we're going crazy without it". IRIX5.3 binary also at ftp.

1995feb26 eds
Added a new 'needle' object (which is really a VU meter) to the sources and updated the executable and the documentation.

1995feb25 dpwe
Updated the commands page to describe the VU meter, the new -command and -docmd options to the scheduler, and the new value command to data sources.

Built under IRIX 5.3 using standard CC and cc - some warnings, but appears to work (had to rebuild gnu's readline lib too - needed to insert "#include <alloca.h>" in sysdep-irix.h). New distribution in ftp://sound/pub/Code/aprl-1995feb25.tgz . Also includes first version of BillG's ptrack object (not documented).

1995feb23 dpwe
Added the 'vumeter' object. fancyclapper.tcl now displays a VU meter reflecting the input signal.

Cleaned up the make files, made a copy of the dpwelib src under /ti/MLGtoolbox/aprl/full-src.

Put aprl-1995feb23.tgz in ~ftp/pub/Code.
