The authors present a collaborative effort on establishing an online course in DSP eartraining. The paper reports from a preliminary workshop that covered a large range of topics such as eartraining in music education, terminology for sound characterization, e-learning, automated tutoring, DSP techniques, music examples and audio programming. An initial design of the web application is presented as a rich content database with flexible views to allow customized online presentations. Technical risks have already been mitigated through prototyping.

This paper describes a method for doing convolution of two live signals, without the need to load a time-invariant impulse response (IR) prior to the convolution process. The method is based on stepwise replacement of the IR in a continuously running convolution process. It was developed in the context of creative live electronic music performance, but can be applied to more traditional use cases for convolution as well. The process allows parametrization of the convolution parameters, by way of real-time transformations of the IR, and as such can be used to build parametric convolution effects for audio mixing and spatialization as well.
