6. Conclusion

This article presents the state-of-the-art in artificial reverberation algorithms for imitating the phenomenon of acoustic reverberation. Since Schroeder's pioneering work in the 1960s, this field of research has been constantly evolving, and today three main families of techniques coexist. The convolutional approach produces a very convincing and "realistic" effect by exploiting the impulse response captured between two positions in a space. It often serves as a benchmark against which other techniques are measured. Thanks to optimized algorithms and the power of today's processors, real-time rendering is possible for many applications. Convolution reverberators are popular in music and film production, where the acoustics of a specific space (e.g. a prestigious concert hall) are desired. However, the approach is not very flexible and remains restricted to static or minimally interactive...
