Constant Q Profiles for Tracking Modulations in Audio Data Format
نویسندگان
چکیده
Cq-profiles are 12-dimensional vectors, each component referring to a pitch class. They can be employed to represent keys. Cq-profiles are calculated with the constant Q filter bank [2]. They have the following advantages: (i) They correspond to probe tone ratings. (ii) Calculation is possible in real-time. (iii) Stability is obtained with respect to sound quality. (iv) They are transposable. Cq-profiles are reliably applied to modulation tracking by introducing a special distance measure.

متن کاملCq-profiles for Key Finding in Audio
Key finding in audio is based on the constant Q transform. A heuristics is suggested how to compress the constant Q transform into a 12-dimensional short-term pitch class profile. Short-term profiles are weighted by a cosine window and summed up yielding long-term profiles. The latter are matched against averaged major and minor prototype profiles.
متن کاملAutomatic Transcription of Polyphonic Music Based on Constant-q Bispectral Analysis for Mirex 2009
This paper describes a new method submitted for MIREX 2009 task: Multiple Fundamental Frequency Estimation & Tracking. Specifically, it is submitted for the first two subtasks: frame by frame evaluation and event contour detection and tracking. In this framework [1], multiple-F0 estimation is carried out by means of a front-end that jointly uses a constant-Q and a bispectral (higher-order spect...
متن کاملMultiple-f0 Estimation and Note Tracking Using a Convolutive Probabilistic Model
This MIREX submission exploits a convolutive probabilistic model for multiple-F0 estimation and note tracking. It extends the shift-invariant Probabilistic Latent Component Analysis method and employs several note templates from multiple orchestral instruments. By incorporating shiftinvariance into the model along with the constant-Q transform as a time-frequency representation, tuning changes ...
متن کاملA Q-learning Based Continuous Tuning of Fuzzy Wall Tracking
A simple easy to implement algorithm is proposed to address wall tracking task of an autonomous robot. The robot should navigate in unknown environments, find the nearest wall, and track it solely based on locally sensed data. The proposed method benefits from coupling fuzzy logic and Q-learning to meet requirements of autonomous navigations. Fuzzy if-then rules provide a reliable decision maki...
