A Tempo Extraction Algorithm for Raw Audio Recordings
نویسندگان
چکیده
This paper presents a tempo extraction algorithm for raw, polyphonic audio recordings, assuming that music meter and tempo remain constant throughout the recording. The method was submitted at MIREX 2006, in the context of the Audio Tempo Extraction evaluation task. Our approach is based on the self-similarity analysis of the audio recording and does not assume the presence of percussive instruments. In order to account for the contest’s requirements, which emphasizes on perceptual tempo tracking, the proposed method returns two tempi, ranging from 40bpm to 320bpm, along with their relative strength.

Music meter and tempo tracking from raw polyphonic audio
This paper presents a method for the extraction of music meter and tempo from raw polyphonic audio recordings, assuming that music meter remains constant throughout the recoding. Although this assumption can be restrictive for certain musical genres, it is acceptable for a large corpus of folklore eastern music styles, including Greek traditional dance music. Our approach is based on the selfsi...
متن کاملBrain Beats: Tempo Extraction from EEG Data
This paper addresses the question how music information retrieval techniques originally developed to process audio recordings can be adapted for the analysis of corresponding brain activity data. In particular, we conducted a case study applying beat tracking techniques to extract the tempo from electroencephalography (EEG) recordings obtained from people listening to music stimuli. We point ou...
متن کاملExtraction and Removal of Percussive Sounds from Musical Recordings
Automated removal and extraction (isolation) of percussive sounds embedded in an audio signal is useful for a variety of applications such as speech enhancement and for music processing effects. A novel method is presented to accomplish both extraction and removal of beats, using an adaptive filter based on the LMS algorithm. Empirical evaluation is undertaken using computer generated music wit...
متن کاملCyclic tempogram - A mid-level tempo representation for musicsignals
The extraction of local tempo and beat information from audio recordings constitutes a challenging task, particularly for music that reveals significant tempo variations. Furthermore, the existence of various pulse levels such as measure, tactus, and tatum often makes the determination of absolute tempo problematic. In this paper, we present a robust mid-level representation that encodes local ...
متن کاملEstimating Tempo, Swing and Beat Locations in Audio Recordings
The problem of estimating the tempo of audio recordings (the number of beats per minute, or BPM) has received an increasing amount of attention in the past few years. Applications include the synchronization of multiple audio tracks for simultaneous playback, ”tempo-synchronous” audio effects, automatic looping of audio tracks... This article presents techniques for estimating the tempo and the...
