摘要： An electronic musical instrument uses a mouthpiece model that models a mouthpiece as a three-dimensional shape having one end at which the mouthpiece is to be held in a mouth of a performer being smaller than another end. A processor in the instrument calculates a reflection coefficient of a progressive wave and a regressive wave using the mouthpiece model by calculating a wave impedance for the progressive wave and calculating a wave impedance for the regressive wave, and generates a musical sound signal on the basis of the calculated reflection coefficient, which is then outputted to a sound generator for sound production.

摘要： A sound detection system of a musical instrument with vibrating parts includes at least a pair of sensors and a preamplification unit for processing the signal output from the two sensors along respective channels. At least one of the pair of sensors is a piezoelectric transducer and the other one of the pair of sensors is a different-type transducer. The preamplification unit includes, for each channel, an input stage, including an amplifier circuit and an equalization circuit, and an output stage including at least a weighted adder circuit and at least two volume controls with arbitrary logarithmic response curve. At least the input stage for the channel of the piezoelectric transducer is a charge amplifier circuit and at least one of the other input stages can be configured both as a charge amplifier and as non-inverting amplifier with high input impedance.

摘要： A method includes generating an audio signal, generating a control signal that is configured to control a haptic feedback device that is incorporated into a device for delivering audio based on the audio signal to a user, and embedding the control signal in the audio signal by using a pseudorandom signal to form an encoded audio signal. Another method includes receiving a signal that includes an audio signal having an embedded control signal, recovering the control signal from the received signal by using a pseudorandom signal, using the recovered control signal to control a haptic feedback device that is incorporated into a device for delivering audio, recovering the audio signal from the received signal, and using the recovered audio signal to generate audio in the device for delivering audio. Systems perform similar steps, and non-transitory computer readable storage mediums each store one or more computer programs.

摘要： A speaker system includes one or more rotating speakers (or speakers with rotating reflectors) that are synchronized in absolute angular position to another rotating speaker or synchronized to audio effects to generated by a signal processing system driving a stationary or rotary speaker. Knowledge of absolute angular position in a multi-rotor speaker array or signal processing system allows for control of rotary position to accomplish acoustic effects otherwise not possible, such as matched-velocity profiles with differential phase control and motion profiles that are not based on simple rotation.

摘要： A delay time counter in a DSP cyclically counts a sampling clock from zero to a delay time sampling count and issues a delay time interrupt to a CPU each time the sampling clock count reaches the delay time sampling count. The CPU measures a time difference between each time the DSP issues the delay time interrupt and each time sequence clock interrupts occur a number of times corresponding to the delay time. Then, in order to reduce this time difference, the CPU increases or decreases a maximum count that is set to the sequence clock counter. Therefore, in the next delay process, the shift between the time by which the automatic performance is advanced by the CPU (which is equal to the delay time) and the timing of the delay process executed by the DSP (which is also equal in length to the delay time) will be corrected.

摘要： An electric instrument music control device is provided having a foot pedal. The foot pedal includes a base portion and a treadle, wherein the treadle moves with respect to the base portion. The device further has a magnetic displacement sensor coupled to the base portion and a magnet coupled to the treadle. The magnet is located adjacent the magnetic displacement sensor to place the sensor in a field-saturated mode, wherein the magnet moves with respect to the magnetic displacement sensor in response to movement of the treadle with respect to the base portion. A sound characteristic of the electric instrument is modified in response to moving the magnet with respect to the magnetic displacement sensor.

摘要： Among other things, techniques and systems are disclosed for detecting musical structures, such as downbeats. In one aspect, a method performed by a data processing device includes receiving an input audio signal. The method includes detecting a meter in the received audio signal. Detecting the meter includes generating an envelope of the received audio signal; generating an autocorrelation phase matrix having a two-dimensional array based on the generated envelope to identify a dominant periodicity in the received audio signal; and filtering both dimensions of the generated autocorrelation phase matrix to enhance peaks in the two-dimensional array. The meter represents a time signature of the input audio signal having multiple beats. Additionally, the method includes identifying a downbeat as a first beat in the detected meter.
