The change tempo effect was modified in commit 8e0089c.
The most significant change is to include the "from" length in the accessibility name of the "to" length textctrl. (The nvda screen reader cannot access the value of the "from" length textctrl, and it's not straightforward using Jaws. Note that this issue existed before the recent change of Change Tempo.)
There remains a minor issue of Jaws, but not NVDA reading the names of wxStaticBoxes, and so some repetition in what is read by Jaws.
When using FloatingPointValidator and calculating the min / max
range as floats or doubles, the validated control value has been
rounded to 'n' decimal places, but the min / max range have not
been rounded. It is therefore a matter of chance whether the
rounded control value, when at the extreme limit of the range,
is within the higher precision range or not.
Non-linear effects now process tracks before mixing.
This will be slower when multiple tracks are selected
but the preview should now match the applied effect.
SetLinearEffectFlag(true) allows linear effects to
preview more quickly when multiple tracks selected, by
pre-mixing selected tracks.
Simple generators like Tone and Noise may be marked as
'linear' so that they only preview a few seconds.
Generators that vary over time (such as Chirp) must use
the full duration that is set. As this currently
requires calculating the full duration, preview for
'non-linear' generators are not limited to the preview
length.
This brings the builtin, LV2, and VAMP effects inline with the
Audio Units, LADSPA, and VST effects. All effects now share
a common UI.
This gives all effects (though not implemented for all):
User and factory preset capability
Preset import/export capability
Shared or private configuration options
Builtin effects can now be migrated to RTP, depending on algorithm.
LV2 effects now support graphical interfaces if the plugin supplies one.
Nyquist prompt enhanced to provide some features of the Nyquist Workbench.
It may not look like it, but this was a LOT of work, so trust me, there
WILL be problems and everything effect related should be suspect. Keep
a sharp eye (or two) open.
