Polyphonic tuner

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 resolution 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 resolution 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 resolution and said monophonic characteristics in a second resolution, wherein the established second resolution of a displayed pitch frequency is higher in monophonic display mode than the established first resolution of the same pitch frequency in polyphonic display mode.
