In this paper, we propose an error estimate algorithm (EEA) for stereophonic acoustic echo cancellation (SAEC) that is based on an extension of the set-membership normalized least mean-squares (SM-NLMS) algorithm combined with the affine projection (AP) algorithm. In the EEA, with the minimum error signal fixed, we compute the filter lengths so that the error signal may approximate the minimum ...

This paper investigates two subjective responses to a recorded percussive musical instrument sound displayed in a hapticauditory virtual environment; the responses were Apparent Motion Towards (AMT) and Powerfulness. The system employed a wholebody actuator and a full-range multichannel stereophonic sound compliant with ITU standards. AMT was experienced when whole-body vibratory components wer...

A computational model of perceived spaciousness in recorded musical signals, inspired by research in music information retrieval (MIR), is presented and evaluated experimentally. First three dimensions of spaciousness are selected for computational modeling: width of source ensemble, extent of reverberation, and extent of immersion. Next human subject responses to stereophonic music along these...

In this paper we present a novel sound source separation algorithm which requires no prior knowledge, no learning, assisted or otherwise, and performs the task of separation based purely on azimuth discrimination within the stereo field. The algorithm exploits the use of the pan pot as a means to achieve image localisation within stereophonic recordings. As such, only an interaural intensity di...

Non-Negative Matrix Factorization is well known to lead to considerable successes in the blind separation of drums and melodic parts of music recordings. Such splitting may well serve as enhancement when it comes to typical Music Information Retrieval tasks as automatic key labelling or tempo detection. In this respect we introduce the combination of an NMF based blind music separation into sev...
