Overview
THIMEO Audio Technology Stereo Tool Professional Software
Stereo Tool is a software-based audio processor which offers outstanding audio quality and comes with many unique features. It is used by over 3000 FM stations ranging from small local stations to 50-100 kW stations and nation-wide networks with dozens of transmitters, thousands of streaming stations and many DAB+, HD, AM and TV stations. It can be used for both live and file based processing.
About THIMEO Audio Technology
Thimeo Audio Technology was founded by Hans van Zutphen. Hans studied computer science at the University of Nijmegen, the Netherlands, and before starting Thimeo he worked at ASML and Philips Healthcare. He always loved radio and in 2001 he ended up creating his own online station, for which he created audio processing software.
Today, Thimeo Audio Technology audio processing products are used by broadcasters in over 100 countries. Thimeo Audio Technology is also integrated into dozens of other manufacturers equipment worldwide. Thimeo Audio Technology products include Stereo Tool, MicroMPX, Watchcat, ST-Enterprise, and STXtreme. Thimeo now has a team of engineers and support staff in both Europe and North America.
Features
The Professional version of Stereo Tool adds a special Composite Clipper to the processing. The Composite Clipper takes the stereo pilot, stereo encoding and RDS into account when generating the composite MPX signal, which increases the headroom for audio by several dB's. You can typically generate a signal that's 2-3 dB louder without sounding more clipped, which results in a much more dynamic and much higher fidelity signal. Beside that it unlocks our "Asymmetric L-R" mode, which adds another 1 dB or so. Beside these advantages to the audio signal, the clipper can also analyze the RF spectrum after the exciter, and optimize the signal to reduce reception issues in fringe areas and in multipath areas.
If you can use Stereo Tool to generate the composite MPX signal, we highly recommend the FM Professional version, which sounds much better and improves your reception.
