Abstract
There is provided a wind synthesizer controller playable by the same manipulation as that of a customary musical instrument as well as able to obtain accurate scale information and volume information. The wind synthesizer controller includes a microphone, an expiration intensity measuring unit, and a controller. The microphone detects a sound generated by flowed in expiration. The expiration intensity measuring unit measures intensity of the expiration on the basis of a detected sound signal. The controller generates volume information on the basis of the measured expiration intensity. The volume information at least includes note on, note off, and velocity.
Claims13
A wind synthesizer controller comprising:
- a microphone detecting a sound generated by flowed in expiration;
- an expiration intensity measuring unit measuring intensity of the expiration on the basis of a detected sound signal;
- and
- a controller generating volume information on the basis of the measured expiration intensity,
- wherein the volume information at least comprises note on, note off, and velocity,
- wherein the expiration intensity measuring unit filters the detected sound signal and passes a frequency band of a set cutoff frequency or lower, calculates a first DC voltage output for the filtered frequency band, and measures the first DC voltage output as first expiration intensity, and
- wherein, when the first DC voltage output is not smaller than a set threshold value, the expiration intensity measuring unit calculates a second DC voltage output for the sound signal detected by the microphone and measures the second DC voltage output as second expiration intensity.
