Multiband compressor limiter for radio broadcasters

Free Download

Your rating: not submitted

Sonos is a software multiband compressor limiter in real time for radio broadcasters. With this tool and a appropriate sound card it is likely to turn a Microsoft Windows computer into an radio broadcast processor. The processor attains its loudness over the use of a particular distortion masked final clipper.


Sonos blends to sound cards using ASIO or the Microsoft Windows native multimedia sound interface.If you choose to use ASIO interface then low latency mode is available.Use of ASIO is reliant upon the sound card possessing ASIO drivers.Most of the professional sound cards are supporting ASIO.

To prevent illegal tampering the application is password protected.

Sonos can be directly started when Microsoft Windows starts. Also the application can be made to minimize to the system tray.

Sonos works with multiple instances. In theory is possible to have more than twenty processors but CPUs are not strong enough yet to cope all twenty processors.

The processor is the principal feature of Sonos. There are three distinct processors ready to use mainly contrasting in the number of bands The nine band (MBL9) is the suggested choice but it may weigh down some PCs so to lower CPU load a processor with fewer bands can be picked. All four processors share typical parts like the four stages of parametric equalization, stereo enhancer, filtering for FM and AM, stereo widener, phase rotator, convertible pre-emphasis for FM. The processor architecture is related in every of the five processors. Dual band gated AGC is pursued by a gated multiband limiter freely anticipated by a multiband compressor. Single band gated confinement is applied before the last clipper. Pre-emphasis for FM is used partly before the multiband section and partly after the last clipper. The processor settings are completely customizable with easy to use saving and loading of preset files. There is a Daypart planner to enable adjustments of preset by time of day or day of the week. The processors have a Fail Over or failsafe option that changes the input to a backup should the principal source fail. The processor can be disabled to decrease CPU load.

It is likely to drive FM transmitter MPX inputs straight from Sonos. It requires a 192kHz sound card with decent bandwidth to pass the MPX signal. The stereo multiplex encoder has customizable clipping for more loudness. The pilot volume amplitude is customizable. The RDS and RBDS encoder is working with all the basic RDS features plus it has a scrolling Program Service Name feature with various messages that can be set up as a rotation. Also there is a means of showing actual track information. The SCA generator works with frequencies from 20kHz up to 90kHz and deviation from 1kHz up to10kHz.


  • Supports multiple instances.
  • It's compatible with all Windows editions.


  • The sound quality is not as good as expected.
