| titleOfInvention |
Input apparatus of electronic system for extracting pitch data from compressed input waveform signal |
| abstract |
An input waveform signal is first converted into a compressed waveform signal by log-conversion. The compressed waveform signal is then converted into a digital compressed waveform signal so that a pitch of the input waveform signal is extracted from the digital compressed waveform signal. Note-on/off states of a musical tone to be produced are controlled in accordance with the level of the digital compressed waveform signal and a predetermined threshold. The attenuation period of the input waveform signal and, thus, the note-on time, can therefore be prolonged to correspond more closely with the actual playing of an instrument from which the input waveform signal is obtained. |
