Adaptive digital audio effects can be developped according to several forms, depending of the number of processed sounds, the channel number of sounds, from which sound features are extracted. Auto-adaptive (or internal) Fx
Cross-adaptive (or external) Fx
Multichannel adaptive Fx Of course, adaptive Fx can be multi-channel Fx. In that case, features are extracted from each channel as well as cross-features (that describe the relationship between channels).
Feedback adaptive effect The forms presented previously(auto-adaptive, cross-adaptive and multi-channel) extracted features from input sound. They are feedforwar forms. Their alos exist feedback forms, where features are extracted from the processed sound, such as in adaptive filtering as developped for telecommunication applications.
