Expressive modifications of Musical audio recordings: Preliminary Results
نویسندگان
چکیده
A system is described that aims to modify the performance of a musical recording (classical music) by changing the basic performance parameters tempo, sound level and tone duration. The input audio file is aligned with the corresponding score, which also contains extra information defining rule-based modifications of these parameters. The signal is decomposed using analysis-synthesis techniques to separate and modify each tone independently. The user can control the performance by changing the quantity of performance rules or by directly modifying the parameters values. A prototype Matlab implementation of the system performs expressive tempo and articulation modifications of monophonic and simple polyphonic audio recordings.

A prototype system for rule-based expressive modifications of audio recordings
A prototype system is described that aims to modify a musical recording in an expressive way using a set of performance rules controlling tempo, sound level and articulation. The audio signal is aligned with an enhanced score file containing performance rules information. A timefrequency transformation is applied, and the peaks in the spectrogram, representing the harmonics of each tone, are tr...
متن کاملSymbolic and Audio Processing to Change the Expressive Intention of a Recorded Music Performance
A framework for real-time expressive modification of audio musical performances is presented. An expressiveness model compute the deviations of the musical parameters which are relevant in terms of control of the expressive intention. The modifications are then realized by the integration of the model with a sound processing engine.
متن کاملRule-Based Expressive Modifications of Tempo in Polyphonic Audio Recordings
This paper describes a few aspects of a system for expressive, rule-based modifications of audio recordings regarding tempo, dynamics and articulation. The input audio signal is first aligned with a score containing extra information on how to modify a performance. The signal is then transformed into the time-frequency domain. Each played tone is identified using partial tracking and the score ...
متن کاملA Machine Learning Approach to Discover Rules for Expressive Performance Actions in Jazz Guitar Music
Expert musicians introduce expression in their performances by manipulating sound properties such as timing, energy, pitch, and timbre. Here, we present a data driven computational approach to induce expressive performance rule models for note duration, onset, energy, and ornamentation transformations in jazz guitar music. We extract high-level features from a set of 16 commercial audio recordi...
متن کاملUsing Musical Knowledge to Extract Expressive Performance Information from Audio Recordings
A computer system is described which performs polyphonic transcription of known solo pianomusic by using high-level musical information to guide a signal-processing system. This process, which we term expressive performance extraction, maps a digital audio representation of amusical performance to a MIDI representation of the same performance using the score of the music as a guide. Analysis of...
