audiowmark-0.6.1 is now available at

Overview of Changes in audiowmark-0.6.1:

* improve speed detection/correction
- performance optimizations to make --detect-speed faster
- improve accuracy of speed detection
- make it work properly with short payload
- add second, slower / more accurate algorithm (--detect-speed-patient)
* fix segfaults during hls-prepare (#11)
* read all input if a process provides audio on stdin to avoid SIGPIPE (#19)
* improve infrastructure for testing audiowmark
- run some scripts for 'make check' to ensure everything works correctly
- add CI which builds/tests audiowmark automatically using github actions
- support various sanitizer builds / STL C++ debug builds
- fix some issues triggered by sanitizers
* add --strict option: provide strict and more permissive mode
- "input frames != output frames" is only an error if --strict is used
- enforce payload size if --strict is used
* improve command line parsing error messages
* documentation updates
* minor fixes

audiowmark is an open source solution (GPL3 or later) for watermarking
audio files. It has many features, it is robust, fast, secure and of
course we believe that the watermark is not audible for most users.

The project page provides the documentation and source code as well as
some audio demos, so you can check whether you hear a difference between
original and watermarked files.
