Comment 6 for bug 1832059

As I understand it, with the lsp-plugins requirement, this will not be accepted into Debian until after lsp-plugins has been accepted (I already wrote an ITP: bug for that). Unfortunately, lsp-plugins does not build for all architectures (per the author), which means that, as I understand it, lsp-plugins will not be accepted into Debian. With that, I doubt PulseEffects would be accepted as well since it requires lsp-plugins to operate.

Unless I'm wrong, I believe the only chance this has to be included in Ubuntu would be the direct route, which yes, means more work for a sponsor.
