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.
This enhancement allows the User to set 'Ratio' to a between 1.1 and 10, with 0.1 precision.
Formerly, the minimum was 1.5, and the smallest increment was 0.5.
... Busy-waiting will happen on Mac when modal dialogs are open, and a LADSPA,
VST, or AudioUnits effect is also open with "fancy" interface.
Busy-waiting will not happen for modal dialogs at other times.
This is using the same idiom of only capturing if not capturing already. These cases in AutoDuck, Resizing, Grabber and TQP might have been latent ASSERTs. This based on precedent rather than actual elicited buggy behaviour.
I confirmed that the currently used real FFT code in RealFFTf.cpp is faster
than the old one with a quick benchmark that calls PowerSpectrum() on 4-minute
audio file, with different sizes of computation windows:
Window_size: 256 method: new FFT time_s: 0.393
Window_size: 256 method: old FFT time_s: 1.065
Window_size: 1024 method: new FFT time_s: 0.38
Window_size: 1024 method: old FFT time_s: 0.958
Window_size: 4096 method: new FFT time_s: 0.413
Window_size: 4096 method: old FFT time_s: 1.084
Window_size: 16384 method: new FFT time_s: 0.518
Window_size: 16384 method: old FFT time_s: 1.338
Window_size: 65536 method: new FFT time_s: 0.655
Window_size: 65536 method: old FFT time_s: 1.524
Window_size: 262144 method: new FFT time_s: 0.735
Window_size: 262144 method: old FFT time_s: 1.873
Now supports stereo tracks. Several tweaks to error messages,
validation logic, and accuracy improvements.
Includes a fix for summary64K (incorrect rms drawn on zoomed
out waveform).
