@knorth55 any interest in maintaining it? From glancing over your PRs and the repo, it looks awfully unmaintained. If this is important to you & you rely on it, you may consider petitioning for maintainership/admin on the repo.
@smac Yes, @k-okada and I are interested in maintaining the repository. Our robot system heavily relies on audio_common repo, so the maintenance quality of the repo is a big issue for us, too.
Sorry; I haven’t really had time to manage the bug reports or contributions to audio_common for a while. I’ve granted @k-okada and @knorth55 write access to this repository and https://github.com/ros-gbp/audio_common-release so that they can do maintenance and releases.
