Research on auto-harmonizing a melody (e.g. Chinese folksong) with piano accompaniment is trying to build up a computer system which generates a 3-voice music including piano left-hand voice and right-hand voice beside an input melody voice. This research belongs to the automatic harmonization field. Here we approach Chinese folksong harmonization with piano accompaniment as a machine learning task,...
Automatic discrimination of musical signal types as speech, singing, music, genres or drumbeats within audio streams is of great importance, e.g. for radio broadcast stream segmentation. Yet, feature sets are largely discussed. We therefore suggest a large open feature set approach starting with systematical generation of 7k hi-level features based on MPEG-7 low-level-descriptors and further feature...
This paper deals with the Music/Speech classification problem, starting from a set of features extracted directly from compressed audio data. The proposed classification system is able to label audio sequences stored as compressed MPEG layer III files. Decoding and analyzing in a unique stage is a fundamental tool for audio streaming applications, such as real time classification. Moreover, the techniques...
