Audacity 3.4.0

Audacity 3.4 adds a musical view, time stretching and a new exporter.

• Music workflows Audacity now features several music related features, such as switching between hh:mm:ss time and Beats & Measures, and time-stretching clips to align them to a song's tempo.
• Time stretching Hold Alt (macOS: Option) while hovering over the top third of a clip edge to stretch it.
• New exporter Audacity now features a new export window with easier access to options such as sample rate and custom mapping (for 5.1 or 7.1 audio). Additionally, the "Browse" button uses the native file browser now!
• For MP3, Audacity now always uses Joint Stereo mode, which always delivers the best possible quality.
• Simplified pasting logic. #4720
