# Updates for TarsosDSP

TarsosDSP is a Java library for audio processing I have started working on more than 10 years ago. The aim of TarsosDSP is to provide an easy-to-use interface to practical music processing algorithms. Obviously, I have been using it myself over the years as my go-to library for audio-processing in Java. However, a number of gradual changes in the java ecosystem made TarsosDSP more and more difficult to use.

Since I have apparently not been the only one using it, there was a need to give it some attention. During the last couple of weeks I have found the time to give it this much needed attention. This resulted in a number of updates, some of the changes include:

-   Change of the build system from Apache Ant to Gradle

-   Make use of Java Modules to make TarsosDSP compatible with the ModulePath introduced in Java 9.

-   Packaged the software into a maven compatible format, which makes it easy to use as a dependency.

-   CI with GitHub actions to automatically build and test the software.

-   Updated some examples shipped with the TarsosDSP. I have still still some examples to verify.

-   Improved handling of errors on reading audio via ffmpeg

Notably **the code of TarsosDSP has not changed much** apart from some cosmetic changes. This backwards compatibility is one of the strong points of Java. With this update I am quite confident that TarsosDSP will also be usable during the next decade as well.
