Realtime Audio Reverb

A reverb module in VHDL for the digital audio processor in FPGA

Reverb is calculated with pre processed damping according to the behavior of the air and reflection parameters of virtual walls. PreDelay and variation of local delays are possible. The RAM-length maybe changed manually or automatically. To cause a most useful effect, statistical noise is used to create a kind of random reflection pattern. This is supposed to create the most natural reverb and is currently discussed to be used for surround sound. All values for damping, room size and material are parametric during compilation and runtime.

The reverb module can be used to add and subtract reflections to / from the audio material. It is also possible to add negative signals to the material in real time in order to pre compensate room reflections like it is known from echo cancelling.

Hear the difference of the Reverb for a demo sequence (e-Mu Proteus Demo song):
