1-June: add-to-menu and remove-from-menu can affect the popup menu.
region handling changed to use the region "id", not its current stack position.
many related changes:
region-* procedures take the id as the region number argument.
removed: select-region, select-region-hook, id-region, region-id
renamed: delete-region -> forget-region.
selection-chans, selection-srate (since regions may be disassociated from the selection).
with-big-colormap is now the default.
removed all the map and scan functions except map-chan and scan-chan
(the rest can be easily re-implemented using loops, sample-readers, set-samples, and sync -- see examp.scm).
removed all the temp-to-sound|selection (and vice versa) functions (and temp-filenames)
(these were redundant since set-samples can take a filename -- see examp.scm for re-implementations)
Snd version 5.0 due to these changes.
added channel arg to save-selection and set-samples (for multi-file selection saves)
make-selection (examp.scm).
removed env-base.
29-May: combined channel-style and uniting under the name channel-style (uniting removed).
dac-folding -> dac-combines-channels (not sure about this name change).
C-x x|n|x_x|n key support ("eval expression") removed (was useless and broken).
These four keys can be re-implemented using bind-key and as-one-edit.
c-g! (simulates typing C-g).
28-May: renamed enved-exping -> enved-exp?, enved-waving -> enved-wave?, enved-clipping -> enved-clip?
amplitude-env -> enved-amplitude, srate-env -> enved-srate, spectrum-env -> enved-spectrum
removed save-state-on-exit (use exit-hook with save-state).
removed activate-listener and hide-listener (the latter is now (set! (show-listener) #f)).
27-May: replaced mix-sound-channel and mix-sound-index by mix-home.
player-home.
Added "control" to the various control panel names:
amp -> amp-control, contrast -> contrast-control, contrast-amp -> contrast-control-amp,
contrast-func -> contrast-control-procedure, contrasting -> contrast-control?, expand -> expand-control,
expand-hop -> expand-control-hop, expand-length -> expand-control-length, expand-ramp -> expand-control-ramp,
expanding -> expand-control?, filtering -> filter-control?, filter-order -> filter-control-order,
filter-env -> filter-control-env, reverb-decay -> reverb-control-decay, reverb-feedback -> reverb-control-feedback,
reverb-funcs -> reverb-control-procedures, reverb-length -> reverb-control-length, reverb-lowpass -> reverb-control-lowpass,
reverb-scale -> reverb-control-scale, reverbing -> reverb-control?, speed -> speed-control, speed-as-float -> speed-control-as-float,
speed-as-ratio -> speed-control-as-ratio, speed-as-semitone -> speed-control-as-semitone, speed-style -> speed-control-style,
speed-tones -> speed-control-tones, filter-dBing -> filter-control-in-dB, enved-dBing -> enved-in-dB.
renamed filter-env-order -> enved-filter-order.
Some rationale:
Scheme uses "procedure" rather than "function" and "?" for booleans.
The control names ("amp" in particular) were too likely to be confused or shadowed.
filter-env-order was too similar to filter-order (and not obvious it meant the envelope editor filter order)
These names actually predated the decision to use Guile -- I didn't foresee 4 years ago where Snd was headed.
26-May: removed fit-data-on-open; here's a replacement:
(define (fit-data snd chn dur)
(let ((mx (maxamp snd chn)))
(list 0.0 dur (- mx) mx "time" (- mx) mx)))
(add-hook! initial-graph-hook fit-data #t) ; #t to make sure env restorers get to function first
added 'extended' arg to bind-key et al so C-x keys can be bound.
example of zero-crossing based C-p, C-n, and C-k in extsnd.html (bind-key).
save-control-panel renamed save-controls, similarly for reset-controls and restore-controls
(these now parallel show-controls and apply-controls).
mark->sound renamed mark-home (the arrow is out of place here, and it's returning the sound-channel list).
sample-reader-home.
25-May: removed open-alternate-sound -- is exactly the same as close-sound + open-sound.
removed earlier scm_apply optimizations ("Rule #1 of optimization: don't do it").
removed normalize-on-open (use after-open-hook and equalize-panes):
(add-hook! after-open-hook (lambda (snd) (equalize-panes)))
renamed normalize-view to equalize-panes.
24-May: removed line-size, prefix-arg (it's now an optional arg to the key function).
ignore-prefix arg to bind-key removed, Snd no longer handles prefix itself.
removed cut (use delete-selection).
call-apply renamed apply-controls.
prompt-in-minibuffer callback func now takes only the response arg (no longer the snd index).
23-May: OSS fragment defaults changed -- see extsnd.html or HISTORY.sndlib.
old default was (set-oss-buffers 4 12) but 2 12 is usable in most cases.
fft-smoother added to examp.scm.
smooth renamed smooth-sound.
22-May: widget-text (mainly for auto-testing).
21-May: Gtk version can now use the mozilla embedded browser for the help dialog.
hankel-jn (default 0.0) for Bessel choice in Hankel transform.
removed raw-srate, raw-chans, raw-format, and use-raw-defaults (use open-raw-sound-hook instead), erase-rectangle.
mouse-enter|leave-text-hook now works in Gtk version as well as Motif.

18-May: Gtk+ version was forgetting to make the listener menu active! (thanks to Dave Phillips)

16-Mar: read|write-peak-env-info-file.
15-Mar: tested ok with gtk 1.2.9.
src-sound with negative envelope bugfix, also the interpretation of the
envelope arg is changed to be consistent with the envelope editor src function.
'(0 1 1 1) now returns no change (src ratio of 1 throughout -- the value is used
directly, rather than being an offset from 1.0.
14-Mar: dac reverb segfault in ALSA with Midiman delta bugfix (thanks to Oded Ben-Tal).
peak-env-info.
13-Mar: removed initial-x0, initial-x1, initial-y0, initial-y1, and replaced with
