Landmark-Based Audio Fingerprinting for DJ Mix Monitoring
نویسندگان
چکیده
Recently, the media monitoring industry shows increased interest in applying automated audio identification systems for revenue distribution of DJ performances played in discotheques. DJ mixes incorporate a wide variety of signal modifications, e.g. pitch shifting, tempo modifications, cross-fading and beat-matching. These signal modifications are expected to be more severe than what is usually encountered in the monitoring of radio and TV broadcasts. The monitoring of DJ mixes presents a hard challenge for automated music identification systems, which need to be robust to various signal modifications while maintaining a high level of specificity to avoid false revenue assignment. In this work we assess the fitness of three landmark-based audio fingerprinting systems with different properties on real-world data – DJ mixes that were performed in discotheques. To enable the research community to evaluate systems on DJ mixes, we also create and publish a freely available, creative-commons licensed dataset of DJ mixes along with their reference tracks and song-border annotations. Experiments on these datasets reveal that a recent quad-based method achieves considerably higher performance on this task than the other methods.

Many radio stations and night-clubs employ Disk-Jockeys (DJs) to provide a continuous stream or “mix” of music, built from a sequence of individual song-tracks. In the last decade, commercial pre-recorded compilation CDs of DJ mixes have become a booming market. DJs exercise skill in deciding an appropriate sequence of tracks and in mixing 'seamlessly' from one track to the next. Online access ...

DJ mixes and radio show recordings constitute an important and underexploited music and data source. In this paper we try to approach the problem of separation of a continuous DJ mix into single tracks or timestamping a mix. Sharing some aspects with the task of structural segmentation, this problem has a number of distinctive features that make difficulties for structural segmentation algorith...
