Other techniques like overlap save/overlap add
The traditional overlap-add technique cannot be used as is in musical applications (reverberation) where latency is critical. It is a common practice to break down the impulse response into non-uniform chunks, and to run in parallel different convolvers for each segment of the impulse response - some of them being naive FIR implementations (for the short blocks at the "head" of the response), and some of them being high-latency overlap-add FFT convolvers.
