The FFTConvolver is able to do short convolutions with the FFT size N being at
least twice as large as the length of the short impulse response. It incurs a
latency of N/2 sample-frames. Because of this latency and performance
considerations, it is not suitable for long convolutions. Multiple instances of
this building block can be used to perform extremely long convolutions.
