Sonos 4 download
Sonos 4 is a software real time multiband FM processor for broadcasters. With a suitable sound card it is possible to turn a Windows PC into a broadcast limiter. The processor achieves its loudness through the use of a distortion masked final clipper (a distortion cancelled clipper). The sound quality and loudness is close to industry standard Optimods and Omnias.

Sonos 4 is no longer available. It has been replaced by Radio Optimizer.

Maxx is a tool for final limiting or mastering of audio files in production environments. There is a manual interactive mode and a batch file processing mode using either a new two band (MBL2) processor or a nine band  processor based on MBL6 from Sonos 4.

Maxx has been replaced by Studio Optimizer.


Hellfire is the next thing in processor development. The Hellfire hardware processor will be released sometime in 2018.

Hopefully by Christmas 2017 a demo of the new processor design will be released as a stripped down version of the Radio-Optimizer. This will enable nothing more than playing of audio files through the new processor to a sound card output.

The hardware will run a Linux on an regular PC motherboard/processor with a custom soundcard designed for broadcast radio use.
