While FDNs address several problems in previous reverberation filters,
the following areas could benefit from further attention:
- Spatialization of reverberant echoes
- HRTF for initial early reflection (Kendall and Martens)
- Diffuse field illusion for late reverb?
(Current approach is simply decorrelating each channel.)
- Mode frequency distribution
- Coupled delay-line systems tend to have uniform mode density
- Natural mode densities increase with freq. squared
- However, note that perception of mode density decreases with frequency
- Is a uniform distribution a good compromise between nature and perception?
