.
Both the 7-tap and 19-tap versions have been implemented, and can be selected
via the checkbox in the Parameter Window. For stereo signals,
the same FIR filter parameters are used for each channel.
NOTE: the 19-tap version is taken from a highly-idealized geometric simulation of the
Boston Symphony Hall!
The FIR delays are implemented using circular buffers.

Signal Implementations
| Audio signals | Control signals | Description |
|---|
| Single input single output mono-mono | n/a | The mono audio input is filtered and sent to the mono audio output. |
| Single input single output mono-stereo | n/a | The mono audio input is filtered and sent (in duplicate) to the stereo audio output channels. |
| Single input single output stereo-mono | n/a | Each audio input channel is filtered separately (but with the same filter coefficients). The filtered channels are then averaged and sent to the mono audio output. |
| Single input single output stereo-stereo | n/a | Each audio input channel is filtered separately (but with the same filter coefficients) and sent to the separate stereo output channels. |
