The commonly used spectral features take into account merely the magnitude information, whereas the phase is overlooked due to the complications related to its interpretation. Additional information concealed in the phase is hypothesised to be beneficial for sound event recognition. The APGD is an approach to inferring phase information, which has shown applicability for analysis of speech and music signals and is now studied in environmental audio. The evaluation is performed within a multi-label deep neural network (DNN) framework on a diverse real-life dataset of environmental sounds. It shows performance improvement compared to the baseline log mel-band energy case. In combination with the magnitude-based features, APGD demonstrates further improvement.", booktitle = "European Signal Processing Conference (EUSIPCO 2015)", keywords = "sound event detection;deep neural networks;all pole;group delay", note = "Accepted for publication", title = "{A}utomatic recognition of environmental sound events using all-pole group delay features", url = "https://www.cs.tut.fi/~diment/papers/Diment15_APGD4events.pdf", year = "2015", }
