Quantec Yardstick - the true measure of room simulation:
The Yardstick 249x series of room simulators are high-quality, digital sound processing devices based on the original 1982 QRS Room Simulation algorithm.
Due to its unobtrusive, natural character and its superb room simulation, the original QRS has become a lot more than just a well-know production tool for pop music. In the fields of classical music production, chamber music, as well as in movie post-production, the QRS is considered to be the Yardstick for all competing products. In other words, whenever a natural sounding ambience is desired, and any kind of artificial reverberation is not, the QRS algorithm has been repeatedly praised by countless sound professionals.
