Sienna Free by Acustica Audio
A free monitoring tool for checking mixes through modeled rooms and a large collection of headphone profiles.

Check how your mix translates
Sienna Free is built for monitoring rather than creative processing. It lets producers audition music through modeled listening environments and headphone emulations, helping reveal balance issues that may be difficult to spot on a single pair of headphones or speakers.
What the free version includes
- Sienna Rooms.
- Guru monitoring tools.
- HOG Sun218 sub room.
- More than 180 measured headphone emulations.
The free edition does not include every feature and room expansion from the commercial Sienna suite, but it still provides a substantial reference toolkit for home studios and headphone-based mixing.
When to use it
Place Sienna Free near the end of your monitoring chain and use it for translation checks rather than exporting processed audio. Compare bass balance, vocal level, stereo placement and brightness across several environments before committing to a final mix or master.
