Abstract
The present invention relates to a musical instrument tuner, e.g. a guitar tuner, featuring different levels of detail for displaying monophonic and polyphonic characteristics of an input signal.
Claims24
A musical instrument tuner comprising:
- an input module,
- a signal analyzer,
- a display,
- a housing,
- a user interface,
- the input module, the signal analyzer and the display forming a part of said
- housing or being comprised in said housing,
- the input module receiving an input signal from a musical instrument,
- the signal analyzer determining at least two characteristics of said input signal,
- the at least two characteristics comprising a monophonic characteristic comprising a representation of a pitch frequency and a polyphonic characteristic comprising a representation of multiple pitch frequencies,
- the display enabling displaying of at least two display modes from a group of display modes, the display modes comprising monophonic display mode and polyphonic display mode,
- in the polyphonic display mode displaying said polyphonic characteristic of the input signal according to a first level of detail, and
- in the monophonic display mode displaying said monophonic characteristic of the input signal, according to a second level of detail,
- wherein the established second level of detail of a displayed pitch frequency is higher in monophonic display mode than the established first level of detail of the same pitch frequency in polyphonic display mode.
A method for displaying tuning information by a musical instrument tuner, the musical instrument tuner comprising
- an input module,
- a signal analyzer,
- a display,
- a housing,
- a user interface,
- the input module, the signal analyzer and the display forming a part of said housing or being comprised in said housing,
- the input module receiving an input signal from a musical instrument,
- the signal analyzer determining at least two characteristics of said input signal,
- the at least two characteristics comprising a monophonic characteristic comprising a representation of a pitch frequency and a polyphonic characteristic comprising a representation of multiple pitch frequencies,
- the display enabling displaying of at least two display modes from a group of display modes, the display modes comprising monophonic display mode and polyphonic display mode,
- the method comprising the steps of
- determining one or more of said at least two characteristics of said input signal to be displayed by said display,
- determining for each of said one or more characteristic to be displayed a display configuration including a level of detail according to one of at least one display mode associated with said characteristic selected from said group of display modes,
- displaying said one or more characteristic to be displayed, whereby a displaying according to a monophonic display mode provides a higher level of detail for a pitch frequency than a displaying according to a polyphonic display mode provides per pitch frequency.
A computer program product comprising a computer readable medium having control logic stored therein for causing a computer to determine and display a characteristic of a musical instrument, the control logic comprising:
- first computer readable program code means for causing the computer to receive an audio signal from said musical instrument;
- second computer readable program code means for causing the computer to determine at least two characteristics of said audio signal from a group of characteristics at least comprising
- one or more monophonic characteristics and
- one or more polyphonic characteristics;
- and
- third computer readable program code means for causing the computer to display said polyphonic characteristics in a first level of detail and said monophonic characteristics in a second level of detail, wherein the established second level of detail of a displayed pitch frequency is higher in monophonic display mode than the established first level of detail of the same pitch frequency in polyphonic display mode.
A musical instrument tuner comprising an input module and a signal analyzer, the input module receiving an input signal from a musical instrument and the signal analyzer determining at least two characteristics of said input signal,
- the at least two characteristics comprising a monophonic characteristic comprising a representation of a pitch frequency having a first level of detail and a polyphonic characteristic comprising a representation of multiple pitch frequencies having a second level of detail,
- wherein the pitch frequency of the monophonic characteristic is determined with a higher precision than each of a majority of the multiple pitch frequencies of the polyphonic characteristic such that the first level of detail is higher than the second level of detail.
