Handheld Acoustic Filter Bank for Musical Control
نویسنده
چکیده
This paper introduces the design of a handheld musical input device that produces control data by measuring, and analyzing, the resonances of carefully tuned pipes. The device provides input control information to several virtual reed instruments running in parallel, responsible for producing the sound. Inspired by the khaen, a musical instrument from Northeast Thailand and Laos, the controller consists of a row of acoustic tubes, with finger holes that change the tube’s resonance when covered. Each tube is equipped with both a microphone recording the change in pressure variations at a set location along the tube. The mic outputs are mixed, and input to the computer via the mic level audio ports, allowing the controller to interface very reliably (and conveniently) to most laptop computers.

A Time-Frequency Adaptation Based on Quantum Neural Networks for Speech Enhancement
In this paper, we propose a novel wavelet coefficient threshold (WCT) depended on both time and frequency information for providing robustness to non-stationary and correlated noisy environments. A perceptual wavelet filter-bank (PWFB) is firstly used to decompose the noisy speech signal into critical bands according to critical bands of psycho-acoustic model of human auditory system. The estim...

In this paper, a novel approach to the transcription of polyphonic signals is investigated. The method makes use of top-down analysis and bottom-up reconstruction of the time-frequency contents of the signals. Time-frequency contents of the signals are obtained using a bank of narrow band filters with very sharp transition band. The filters are designed using the Frequency Response Masking tech...

This paper describes the transformation of an everyday object into a digital musical instrument. By tracking hand movements and tilt on one of two axes, the Bubbaboard, a transformed handheld washboard, allows a user to play scales at different octaves while simultaneously offering the ability to use its inherent acoustic percussive qualities. Processed sound is fed to the Mommaspeaker, which c...

Designing appropriate features for acoustic event recognition tasks is an active field of research. Expressive features should both improve the performance of the tasks and also be interpret-able. Currently, heuristically designed features based on the domain knowledge requires tremendous effort in hand-crafting, while features extracted through deep network are difficult for human to interpret...
