Non-destructive pitch shifting: implement overflow button

1

A `...` button in the top right corner of clips, which allow to open the pitch-and-speed dialog in one click. Figma design (private): https://www.figma.com/file/6kBToiSyv40MOWaNzkxCdj/32_WX---Pitch-%26-Onset-snapping?type=design&node-id=30-761&mode=design&t=PhFBhnaOKVhnO3s8-0

### Your idea Pitch and speed dialog isn't modal anymore, meaning having it open doesn't block interaction with the rest of the UI. ### Problem to be solved Changing speed...

Multi-channel "tracks" don't react to "fit-to-height"

### Bug description Multi-channel tracks (visually presented as multiple mono tracks) don't react when executing "fit-to-height", whether through the View menu or the keyboard shortcut (on Windows). Mono or stereo...

Take trimmed data into account when stretch- and pitch-rendering a track.

1

### Your idea Like we do when joining smart clips of different stretch or pitch ratios, use the trimmed parts left and right to improve the result. ### Problem to...

### Your idea So that neither imaging nor aliasing results from the shift, consider one of the two approaches: * replace the current, rough resampling used by the time-and-pitch library...

Steady tone gets tempo-detected

1

### Bug description [This steady sine wave](https://github.com/audacity/audacity/files/14178090/tempo-detected.sine.zip) gets tempo-detected. While there is some tolerance with false positives when they are in the rhythmic/non-rhythmic grey zone, for such tone the detection...

### Your idea Improve quality of non-destructive pitch shifting with formant preservation. This requires algorithmic modifications in the time-and-pitch library. ### Problem to be solved This is particularly desired for...
