Sam James ba1cb7727e configure.ac: fix bashism in CXXFLAGS assignment
configure scripts need to be runnable with a POSIX-compliant /bin/sh.

On many (but not all!) systems, /bin/sh is provided by Bash, so errors
like this aren't spotted. Notably Debian defaults to /bin/sh provided
by dash which doesn't tolerate such bashisms as '=='.

This retains compatibility with bash.

Fixes configure warnings/errors like:
```
checking whether make supports nested variables... (cached) yes
configure: 3698: CXXFLAGS+= -Ofast: not found
```

SoundTouch library

About

SoundTouch is an open-source audio processing library that allows changing the sound tempo, pitch and playback rate parameters independently from each other:

  • Change tempo while maintaining the original pitch
  • Change pitch while maintaining the original tempo
  • Change playback rate that affects both tempo and pitch at the same time
  • Change any combination of tempo/pitch/rate

Visit SoundTouch website and see the README file for more information and audio examples.

The latest stable release is 2.3.2

Example

Use SoundStretch example app for modifying wav audio files, for example as follows:

soundstretch my_original_file.wav output_file.wav -tempo=+15 -pitch=-3

See the README file for more usage examples and instructions how to build SoundTouch + SoundStretch.

Ready SoundStretch application executables are available for download for Windows and Mac OS.

  • Windows
  • Mac OS
  • Linux & Unices (including also Raspberry, Beaglebone, Yocto etc embedded Linux flavors)
