Abstract
Techniques are described that relate to various aspects of converting the mechanical energy of instrument strings to digital representations for use in a variety of applications.
Claims23
A computer program product, comprising one or more non-transitory computer-readable media having computer program instructions stored therein, the computer program instructions being configured such that, when executed by one or more processors, the computer program instructions cause the one or more processors to:
- receive fretting data representing fretting hand positions for strings of a stringed instrument;
- receive string data representing vibrations of the strings of the stringed instrument;
- determine a first fundamental frequency estimate for a first string of the stringed instrument by performing a spectral analysis of the string data for the first string;
- determine a second fundamental frequency estimate for the first string using the fretting data for the first string;
- determine that the first fundamental frequency estimate for the first string corresponds to a harmonic of the second fundamental frequency estimate for the first string;
- and
- correct the first fundamental frequency estimate for the first string using the second fundamental frequency estimate for the first string.
4 more elements
A device, comprising:
- memory;
- one or more interfaces configured to receive fretting data representing fretting hand positions for strings of a stringed instrument, the one or more interfaces also being configured to receive string signals representing vibrations of the strings of the stringed instrument;
- circuitry for generating string data from the string signals;
- and
- one or more processors configured in conjunction with the memory to:
- determine a first fundamental frequency estimate for a first string of the stringed instrument by performing a spectral analysis of the string data for the first string;
- determine a second fundamental frequency estimate for the first string using the fretting data for the first string;
- determine that the first fundamental frequency estimate for the first string corresponds to a harmonic of the second fundamental frequency estimate for the first string;
- and
- correct the first fundamental frequency estimate for the first string using the second fundamental frequency estimate for the first string.
