Our Freebies are no longer in development, though you can still download them fir older version of MacOS from our Legacy page. It's also likely we have a modern solution to assist with your audio needs.
For fast menu bar access to your Mac's audio devices, as well as much, much more, please see the new SoundSource.
For audio play-thru functionality previously provided by LineIn, we recommend using Audio Hijack.
For robust custom ringtone creation, we recommend our audio editor Fission. Edit any audio file in Fission, then choose “Save as iPhone Ringtone” right in Fission's File menu.
