Investigations into Informed Phase Restoration of Amplitude Spectra for Audio Signals

Transform coding has been extensively used for audio and speech compression applications during the past decades. A widely used transform is the real-valued Modified Discrete Cosine Transform (MDCT), which is employed in several state-of-the-art codecs such as the MPEG-1 Layer III (aka mp3) and AAC. An extension to this transform is the...

Speech Based Onset Estimation for Multisensor Localization

This work presents a study of a current problem in the field of audio processing: Source and receiver localization. Currently, this problem requires that either the onset time of the sources or the internal delay of the receivers are known. The algorithms studied here, take advantage of the structure of the time matrix, which contains the TOA of...
