Introduces a delay ?? I don't think so, the encoding equations are pure
multiplications, each channel of the b-format signal is just the input
multiplied by a certain coeficiient, and the decoding stage is the same.
The phase information is provided by the interactions between the
various speakers, not through delays. As far as I'm aware there is no
"built in reverb".
