A quite popular resampler used in a lot of audio plugins and daws.
Is it Open Source? Yes.
I think there can be several people that will use it and having it in the repo will make it easier to add future audio software.
As this task has been marked Needs Maintainer for a month with nobody having stepped up to become maintainer, in addition to providing an acceptable patch for inclusion, marking as WONTFIX. Feel free to re-open when a patch has been submitted via the proper processes.
