ListenHub

Sonnox ListenHub is a macOS-only monitoring and mix-referencing utility for producers and mixers who want a clearer perspective on their work. Compare your mix with tracks playing through Spotify, Apple Music, YouTube or a local media player, with automatic input level matching to reduce loudness bias. Solo mid or side information, check mono compatibility, and isolate frequency bands to investigate bass balance, stereo width or overlooked details. Loudness, dynamics and spectral meters help you assess how your mix compares with your references, while stepped volume controls make listening levels easy to repeat. ListenHub works as a zero-latency plugin or a system-wide app with AU plugin hosting on each output. A free iOS and Android remote app puts monitoring controls within reach without crowding your computer screen. It suits home studios and professional mixing setups alike, but does not support Windows.
