Definitions

  • the invention relates to a tuning device for a pipe of an organ, wherein the whistle is a tongue whistle, wherein the length of the freely oscillatable region of a tongue of the whistle via an electronic drive element is variable. Furthermore, the invention relates to an electronic tuner for tuning a group of pipes in an organ.
  • a lip whistle the sound is created by refraction of the air on a sharp edge, whereby the oscillation of the air flow creates a swinging column of air (standing wave) in the whistle (comparable to a recorder).
  • a metal tongue is caused by the flow of air in vibration, which have a very different design than lip whistles and are usually not visible housed in the organ.
  • Lip whistles and reeds are also different in terms of voice response.
  • the pitch of the whistles is determined by various methods, e.g. by bending the beards or moving vocal cords at the upper, rear end of the pipe, set in the course of a first intonation. This process usually takes several months with large organs and requires a lot of experience, a good ear and extensive expertise.
  • the pitch is determined not by the vibration of an air column, but by the vibration of the metal tongue, so the pitch of these pipes remains almost constant with temperature changes.
  • the tongue whistles can be tuned almost indefinitely on the basis of the voice crutch, since due to the movable mechanism, no material fatigue occurs.
  • the mood should only be carried out if stable temperature conditions prevail in the installation room.
  • the heating should be switched off, since the different tempered air flow through circulation could already have an impact.
  • churches are heated up at short notice for church services.
  • Even the heat given off by concert goers can already lead to deviations.

  • Fig. 1 the construction of a conventional whistle 2 with a tongue 4 is shown graphically for a better understanding of the operation of reed pipes.
  • the play wind which flows through the injection hole 13 at the base into the pipe foot (boot 14), generates a pressure pW inside the pipe.
  • a voice crutch 3 in the form of a curved wire hanger, presses the tongue 4 against the open side of the air duct designated throat 15, which is the only way out for the air.
  • the tongue 4 has a slight bend (Aufsch), through which it protrudes slightly from the throat 15. As a result, the air can flow into the throat 15, whereby the tongue 4 is sucked in and closes the throat.
  • the tongue Since no more air can penetrate into the throat, the tongue bends 4 back by their rigidity and the Aufsch back to their original position, so that air can flow through again.
  • the pressure pK in the throat 15 is always lower than that in the boot 14.
  • the tongue 4 thus begins to oscillate exactly at its natural frequency, this being dependent on the oscillatory length determined by the voice crutch 3.
  • the resulting sound of the tongue 4 in the air stream can be very strongly amplified and modified by the mouth of the throat 15 in a resonator 16.
  • the shape of the resonator 16 has a significant influence on the sound pattern of the whistle 2.
  • the length of the resonator 16 has by the reflection of the wave at the end of the tube influence on the sound color of the whistle 2 and also on the triggering of the next cycle and thus a minor effect the pitch.
  • the pitch is usually set and the sound quality is varied by varying the resonator length by finding the optimal coupling of the natural oscillations of the resonator and the tongue. Due to the specific design, pipes can be built with countless variations to create different sounds.
  • the pitch depends quadratically on the length of the free oscillating region of the tongue 4. It should be noted that here many variables such as pressure, force, rigidity or even the width can be shortened and the natural frequency depends only on the actual material parameters E modulus and density and the two dimensions length and thickness.
  • the lengths of the metal tongues used in organ pipes range from about 5 mm at the highest to about 200 mm at the deepest pipes.
  • a tongue reacts more sensitively, the smaller their dimensions are. Due to the extremely high sensitivity of the tuning process is particularly cumbersome in the smallest reeds, with the necessary Adjustments can hardly be performed manually because they are so small (a mere touch of the voice crutch is sufficient to influence the sound).
  • the change in length of 0.01 mm for a tongue 8 mm long and 0.1 mm thick causes a calculated pitch deviation of 4.3 cents, which is already audible to the human ear. This means that the adjusting movements necessary for the production of the tuning lie at the Stimmkguren of the small pipes in the ⁇ m range.
  • the change in ambient temperature has no significant effect on the pitch of the reed whistles compared to the whistles.
  • the Applicant has calculated a value of only 0.17 cents, with the temperature-dependent deviation in cents being independent of the pitch.

  • the clamping element 18 may, for example, have a screw which contracts two clamping jaws of the adapter 10, between which the vocal crutch 3 is inserted, and thereby clamps the vocal crutch 3 between the clamping jaws.
  • a clamping screw could also attach directly to the Stimmkgure 3 and clamp them.

This has the advantage that the whistle 2 can continue to be tuned in a conventional manner, to which simply the clamping element 18 is released. The voice crutch can then be operated normally again without the tuning device 1 or the adapter 10 having to be removed.
  • Fig. 3 shows a tuning device 1 with a in the area directly below the nut 17 of a whistle 2 laterally adjacent to the housing 5 arranged drive element 8.
  • a drive element 8 for example, a DC motor can be used, which drives a threaded spindle 19 via a gear 22.

  • the drive element 8 with the gear 22 is also fastened with screws to the mounting member 11. Due to the lower thread pitch of metric threads and the resulting high reduction only a smaller drive torque (about 10-15 Nmm) is required, which relieves the motors used. Furthermore, a high positioning accuracy can be achieved due to the lower pitch, which makes tuning easier, especially with short tongues.
  • Fig. 4a and 4b show in two fracture views a further advantageous embodiment in which the tuning device 1 can be arranged closer to the vocal cuff 7 above the nut 17 of the whistle 2.

  • the adapter 10 is again formed as a plastic block and has substantially the same features as with reference to the embodiment of Fig. 3 have been described. However, the adapter 10 is slightly smaller, since the threaded spindle 19 is arranged very close to the space next to the voice crutch 3.
  • Tuning devices 1 shown have proven in test series carried out by the inventor and combine the advantages of a very high positioning accuracy, a compact size, easy installation options and low acquisition costs.
  • the whistle 2 remains dismountable (eg to remove dirt on the tongue) and the whistle 2 can be tuned manually by loosening the grub screw 42 via the Stimmkgure 3 if necessary (eg in case of failure of the engine).
  • a control loop with a plurality of components can be constructed as shown in FIG Fig. 5 is shown by way of example.

  • the reference variable 26 (the target frequency) changes as a function of the air temperature, since the reeds are adapted to the temperature-dependent pitch of the lip whistles due to the lower number and the gentler tunability.
  • the reference variable 26 can thus be determined, for example, by determining the pitch of a lip whistle or a group of lip whistles used as a reference in the course of the tuning process.
  • the tuner TLA Tuning Set CTS-32-C were used in the prototype phase for frequency detection. It has been specially developed for instrument making and also has some organ-specific setting options (eg historical tuning of temperaments).
  • the working range of the tuner is 9.5 octaves, which is also needed due to the different footings of registers for tuning an organ. It is possible to connect a temperature sensor to the change in ambient temperature during the voting process.
  • An advantage of this device is the accuracy in the sub-cent range, with which the pitch can be measured and the serial interface with which the measurement data can be transferred to a computer via USB interface.
  • the tuner can be remotely controlled via serial interface.
  • the measuring algorithm forms a frequency mean over an adjustable time range (gate time) of 50-1000 ms, since the pitch of a whistle never remains exactly stable, but varies depending on the frequency position. Especially with low tones in the bass range, this fluctuation range is particularly large, in which case can be remedied by increasing the gate time.
  • a gate time of 300 ms can be used, which is then adjusted if necessary.
  • An integrated microphone picks up the current sound and generates a corresponding audio signal.
  • the signal then passes to an analog bandpass filter which filters out unwanted frequencies (and even overtones).
  • the tone to be tuned and thus the filter range of the bandpass filter can be configured on the tuner or via a serial interface.
  • This filtering results in the extraction of a clean sine signal from the complex audio signal (corresponding to the frequency component of the fundamental tone).
  • the frequency of this sinusoidal signal can be determined by means of known algorithms, for example by means of a microprocessor.
  • the tuner used in the prototype phase is expedient, but is very expensive to buy and dependent on the supplier, the inventor has developed his own solution for frequency measurement. It was designed a circuit board on which there are a microphone, a preamplifier and a microcontroller. Due to the low cost of these components, it is also possible to accommodate several microphones at acoustically suitable locations in the organ.
  • the programming of the microcontroller can be based on known algorithms. For example, to determine the fundamental frequency of a tone, numerous algorithms exist, such as e.g. the Fourier transform (used by most tuners) which analyzes the entire frequency spectrum and thus shows which frequency is how strong. Due to the fact that all frequencies are calculated, the calculation takes a relatively long time compared to other algorithms.
  • Fourier transform used by most tuners
  • the target frequency of the currently tuned whistle is always known.
  • the frequency search can be significantly reduced and saved computing time, for example, is searched only within a fixed frequency band.
  • a simple analog bandpass filter can be used (e.g., MF10 from Texas Instruments) that can perform desired filtering of the microphone signal in near real time (the small, constant phase shift is irrelevant).
  • a center frequency can be predetermined by a clock signal, which is filtered out of the input signal and additionally amplified.
  • the bandwidth of the filter around the center frequency, operating mode and gain can be configured with external resistors.
  • Everything outside the defined range is very strongly attenuated by a two-stage filter of 4th order. This makes it possible to isolate the fundamental frequency even with very harmonically rich tones (as they occur especially with tongue registers) and to obtain an approximately clean sine wave as an output signal.
  • Autocorrelation also represents a possible algorithm that multiplies the signal out of phase with itself and detects the fundamental frequency at a maximum.
  • a clock signal was generated, with which the filter frequency can be set.
  • the clock signal for the filter must be one hundred times the filter frequency.
  • the bandwidth of the filter has been configured so that the signal, which is a few semitones next to the set frequency, are already strongly attenuated (attenuation by about -40dB / octave). Since the second harmonic (first overtone) is only at the octave, and thus is very far away, it is already very much attenuated. Thus, it was possible to extract from the complex audio signal a nearly pure sinusoidal oscillation which oscillates exactly at the fundamental frequency of the whistle.
  • This signal was sent to the analog input of the PC and to the Further processing with the integrated analog-to-digital converter (ADC) converted to a digital signal.
  • ADC analog-to-digital converter
  • an autocorrelation method or a zero crossing count can be used. While well-known methods of autocorrelation have provided promising results, they required relatively high computational power compared to other approaches. As an alternative, therefore, the so-called "zero crossing rate" was tested, in which the number of oscillations is determined in a certain time.
  • a microphone generates voltages in the negative and positive range, but in the test setup, the signal was transformed into the positive voltage range because the input of the microcontroller could not measure negative voltages (measuring range 0-5V). Since an exclusively positive voltage signal was available, a voltage threshold was set in the middle of the sinusoidal signal and the number of threshold passes was counted. The number of vibrations to be evaluated was fixed and the frequency was calculated on the basis of the elapsed time when the value was reached. The constant number of oscillations makes it possible to eliminate the risk (as compared to a fixed measurement duration) that, for very low tones (i.e., long period), the measurement result becomes inaccurate due to under-measured oscillations. The more oscillations are counted for measurement, the more stable the calculated frequency, thereby also reducing the speed of the entire vocal process.
  • a very useful option for this application would be to count only a few oscillations at the beginning of the tuning process, when the whistle is still very detuned, to quickly and inaccurately determine the frequency, and when approaching the target frequency, the number of oscillations in the Dynamically increase software to increase the accuracy and stability of the calculation.
  • the motors are anyway only operated by very short pulses, there is correspondingly more time to precisely determine the frequency accordingly.
  • it interpolates linearly at zero crossing (or here by the defined threshold) of the ADC input signal, provided that the measured value does not correspond exactly to the threshold.
  • Fig. 6 shows a schematic representation of the electronic tuner 31 according to the invention, which was developed on the basis of the experimental series described above.
  • the electronic tuner 31 has a microphone 32, which is connected via a preamplifier 33 and a bandpass filter 34 with a microcontroller 35.
  • the microcontroller 35 controls the provided on the pipes 2 of an organ tuning devices 1 via corresponding motor driver 36, wherein the control is carried out in coordination with the executed by the microcontroller 35 algorithms for frequency determination and the sequence of mood.

  • the tuner 31 can be connected via an interface 37, for example, a conventional Ethernet, MIDI or BUS interface to an organ 38, if this organ has a corresponding interface.
  • This makes it possible to control the pipes 2 of the organ 38 directly from the microcontroller in accordance with the mood sequence when the organ 38 is already electrified, ie an autonomous control of sounds is possible.
