Abstract
A recording method acquires, from a first musical instrument which outputs playing data which represents playing information, playing data of playing by the first musical instrument; generates a first waveform signal according to the played sounds of the first musical instrument which correspond to the playing data; generates a second waveform signal according to a sound including a sound emitted from the first musical instrument and other sounds; generates a third waveform signal wherein the first waveform signal is subtracted from the second waveform signal; generates audio data from the third waveform signal; and records the audio data.
Claims15
A recording method comprising:
- an acquiring step of acquiring, from a first musical instrument that outputs musical-performance data representing musical-performance information, the musical-performance data output by the first musical instrument;
- a first waveform generating step of generating a first waveform signal corresponding to played sounds of the first musical instrument according to the musical-performance data;
- a second waveform generating step of generating a second waveform signal corresponding to sounds, including the played sounds of the first musical instrument according to the musical-performance data and other sounds, picked up by a microphone;
- a third waveform generating step of generating a third waveform signal by removing the first waveform signal corresponding to the played sounds of the first musical instrument picked up by the microphone from the second waveform signal;
- an audio data generating step of generating audio data from the third waveform signal;
- and
- a recording step of recording the audio data.
A recording device for recording music from a first musical instrument that outputs a first waveform signal corresponding to played sounds of the first musical instrument according to musical-performance data representing musical-performance information, and other sounds other than from the first musical instrument, the recording device comprising:
- a recorder that receives the musical-performance data from the first musical instrument;
- a microphone that picks up a second waveform signal corresponding to sounds, including the played sounds of the first musical instrument according to the musical-performance data and the other sounds;
- a filter device that receives the second waveform signals output from the microphone, and outputs a third waveform signal where the first waveform signal corresponding to the played sounds of the first musical instrument picked up by the microphone is removed from the second waveform signal;
- and
- a recorder that records audio data that is generated from the third waveform signal output by the filter device.
A recording method comprising:
- an acquiring step of acquiring, from a first musical instrument that outputs musical-performance data representing musical-performance information, the musical-performance data output by the first musical instrument;
- a first waveform generating step of generating a first waveform signal corresponding to played sounds of the first musical instrument according to the musical-performance data;
- a second waveform generating step of generating a second waveform signal corresponding to sounds including the played sounds of the first musical instrument according to the musical-performance data and other sounds;
- a third waveform generating step of generating a third waveform signal by removing the first waveform signal corresponding to the played sounds of the first musical instrument from the second waveform signal;
- an audio data generating step of generating audio data from the third waveform signal;
- and
- a recording step of recording the audio data,
- wherein the musical-performance data is sequence data, and
- wherein the recording step records the audio data paired with the musical-performance data.
