Intelligent Digital Audio Effects (I-DAFx) process audio signals in a signal-adaptive way by using a high-level analysis of the input. Examples are the control of time parameters in tremolos, auto-wahs and vibrato effects using beat tracking, the application of blind source separation techniques to upmixing for multichannel reproduction, and signal-adaptive audio effects using feature extraction. Tools for automated live mixing have been developed recently that analyze the multichannel input of a mixer to control the effects, leveling, and panning. These and other techniques are in the scope of this workshop. It presents an overview of I-DAFx and demonstrations of practical implementations with sound examples.
