Giorgos Siamantas - Thesis audio results

This page presents the audio results of a number of source separation experiments carried out in the Audio Lab of the Department of Electronics, University of York. The audio accompanies the research work carried out during my PhD, which was supervised by Dr John Szymanski and presented in detail in my PhD thesis (see link on the right).

The dB values refer to the RMS energy difference between sources j and j + 1. For example, a ''5 dB'' value indicates that the RMS energy of source 1 is 5 dB higher compared to the RMS energy of source 2, 10 dB higher compared to the RMS energy of source 3, and so on. For a detailed description and discussion concerning the particular experiments, the proposed separation system and the alternative techniques it is compared with [1, 2], please see Ch. 5 and Ch. 6 of the thesis.

For the purpose of carrying out comparisons, the WAV versions of the audio files are also provided in an archived form.
