Rubber Band Library version 1.9.1 released

Version 1.9.1 of the Rubber Band Library is now available.

Rubber Band Library is an audio time-stretching and pitch-shifting library and utility designed for musical applications. It allows you to change the tempo and pitch of an audio recording independently of one another.

Version 1.9.1 is a maintenance release, including a fix that removes some audible artifacts when changing pitch dynamically. This release also changes the default build system from autoconf to Meson, and, although all previous releases in fact work fine on Apple Silicon (ARM) Macs, this is the first one that officially supports that platform as a tested configuration.

The library is binary compatible with versions 1.7, 1.8.x, and 1.9.
