Definitions

  • This invention relates to tuning apparatus and more particularly, although not so restricted, to tuning apparatus, for tuning voice and musical instruments, equipped with a calibration function by means of which an arbitrary tuning reference can be set.
  • the reference pitch for measuring the sound to be tuned is fixed in the conventional tuning apparatus, it has been difficult to effect tuning in a pitch which deviates from the fixed pitch. For instance, in an ensemble of a piano - which is difficult to tune within a short period of time even for those who are skilled in tuning - and another instrument, that other instrument must be tuned using the pitch of the piano as the reference.
  • the deviation of the piano sound from the fixed pitch of the tuning apparatus is first measured, and a tuner who tunes the other instrument memorizes this deviation and tunes the other instrument so that their deviations are substantially equal. Therefore, unless the tuner correctly memorizes the deviation of the piano sound from the fixed pitch of the tuning apparatus, the other instrument will be tuned incorrectly.
  • the mode of use of the tuning apparatus in this case is different from the mode of use for tuning a musical instrument alone, and the tuner will sometimes abuse the tuning apparatus.
  • the present invention seeks to provide a tuning apparatus which measures a sound to be tuned by using the pitch of a frequency predetermined by a player of a musical instrument as the reference pitch for tuning.
  • the present invention also seeks to provide a a tuning apparatus which prevents erroneous tuning by displaying whether or not the measurement of the sound to be tuned is made in the pitch of an arbitrary sound as a tuning reference.
  • a tuning apparatus for extracting the pitch of sound to be tuned and displaying deviation of the extracted pitch from a reference frequency
  • the apparatus being characterised by comprising: external switch means for determining a calibration mode; first memory means for storing the deviation of said sound to be tuned from said fixed reference frequency; second memory means to which said stored deviation data is transferred from said first memory means upon operation of said external switch means; calculation control means for subtracting the data stored in said second memory means from the measured data in said first memory means after operation of said external switch means; and display means for displaying the result of calculation of said calculation control means.
  • the calculation control circuit adds 100% to the result of calculation and outputs data which is a half tone lower than the note to said display means when the result of calculation is smaller than -50%, and subtracts 100% from the result of calculation and outputs data which is a half tone higher than the note to said display means when the result of calculation is greater than +50%.
  • the display means comprises first display means for displaying the result of calculation of said calculation control means, and second display means for indicating that the calibration function is operative.
  • the tuning apparatus may include third memory means for storing a reference table for determining the name of the note of the sound.
  • the third memory means may be arranged to store the result of calculation of the calculation control means.
  • the tuning apparatus may include a counter for producing a signal representative of the timing of the sound.
  • a tuning apparatus includes: a waveform shaping circuit 2 which converts a measured input signal A, which is obtained by converting an audio signal to an electrical signal using, for example, a microphone 1, to a pulse signal B; a pulse control circuit 5 which receives the pulse signal B and applies signals to a counter 3 and a calculation control circuit 4; a reference signal generation circuit 6 which generates a clock signal for the counter 3; an external switch member 7; a switch circuit 8 which generates a switch signal upon operation of the external switch member 7; a first memory circuit 9 which stores a deviation value by a fixed pitch calculated from the count value output from the counter 3 and and the name of a note; a second memory circuit 10 which stores a correction value; a third memory circuit 11 which stores a reference table for calculating the name of a note as well as the deviation value by the fixed pitch in the calculation control circuit 4 described above; a first display device 12 which displays the result of measurement; and a second display device 13 which displays whether or not a calibration
  • the waveform shaping circuit 2 converts the input signal A ( Figure 2) to a pulse signal B.
  • the pulse control circuit 5 controls the counter 3 to count each rise of the pulses of the pulse signal B, and outputs the rise timing t1, t2, t3, t4...to the calculation control circuit 4.
  • the name of the note and the value of the deviation are stored in the first memory circuit 9 and are displayed as shown in Figure 3 by the first display device 12.
  • the switch circuit 8 If the external switch member 7 is closed, the switch circuit 8 outputs a high level signal to the calculation control circuit 4. Then, the calculation control circuit 4 executes calculations in accordance with the flowchart (I) shown in Figure 4. In other words, when receiving a high level signal from the switch circuit 8, the calculation control circuit 5 judges whether or not the first display device 12 displays the name of the note and the deviation value, and if it does, the calculation control circuit 4 transfers the deviation value of the data stored in the first memory circuit 9 to the second memory circuit 10.
  • the name of the tone and the deviation value are calculated as F and +45, for example.
  • the external switch member, the second memory circuit for storing the correction value and the calculation control circuit are provided for executing correction. Therefore, there is provided the effect that the measured value can be tuned at an arbitrary reference pitch. Furthermore, since the second display device is provided, it is possible to display the state where tuning can be made in an arbitrary reference pitch.
