+# 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](https://www.surina.net/soundtouch) and see the [README file](https://www.surina.net/soundtouch/readme.html) for more information and audio examples.
+
+## Version

+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](https://soundtouch.surina.net/README.html) for more usage examples and instructions how to build the software.
