Rayspace reverb features a real-time impulse response designer. It simulates room acoustics while you draw them, and allows you to hear the results immediately!
* Use a set of tools to draw your own complex spaces, from small boxes to huge halls.
* Real surround sound! Uses the front and rear speakers to completely immerse the listener, with echoes and direct sounds coming from real positions.
* Clean sound. No smearing techniques or the usual 'greyness' found in other reverbs. High mix volumes add minimal artificial colour.
* Dampening and filtering wall effects, as well as air absorbency.
* Continuous impulse display, with volume and filter responses.
* Automation of all controls with source and listener movements also recorded in host software.
* Only £30
