A system processes mixed input data using a neural network trained to separate audio data of predetermined timbres from mixed audio data and to obtain a group of decomposed tracks comprising at least first, second, and third decomposed audio tracks representing audio signals of first, second, and third predetermined timbres, respectively. The system reads a control input representing a setting of a first volume level and of a second volume level. The system recombines at least a first selected track and a second selected track selected from the group of decomposed tracks to generate a first recombined track. The system recombines the first recombined track at the first volume level with at least a third track selected from the group of decomposed tracks, at the second volume level, to obtain a second recombined track. The system plays the audio data based on the second recombined track.

An electronic musical instrument comprising a plurality of keys that includes a first and a second key having a pitch in a harmonic relationship with a pitch of the first key; and at least one processor. wherein the at least one processor performs the following: deciding, in response to a operation of a first key, whether the second key is in a damped state or in a non-damped state; generating, in a case where the second key is in the non-damped state, a resonance tone corresponding to the second key with at least one of a first resonance pitch and a first timbre; and generating, in a case where the second key is in the damped state, the resonance tone corresponding to the second key with at least one of a second resonance pitch and a second timbre.

An electronic wind instrument includes a tonguing sensor which detects tonguing, a breath sensor which detects a breath value, a loudspeaker which outputs a musical sound and a processor which controls the musical sound, in which the processor acquires a tonguing value which depends on a tonguing time which is the time which has elapsed after start of the tonguing which is detected by the tongue sensor, decides a silencing effect value which indicates a degree of volume reduction depending on the tonguing value, acquires the breath value which depends on a magnitude of a breath sensor signal which indicates a result of detection by the breath sensor and makes the loudspeaker emit the musical sound whose volume which depends on the breath value is reduced depending on the silencing effect value.

A method of and system for generating audio having pitch attributes of an incoming audio stream. The method comprises receiving a digital audio input. The audio spectrum is analyzed and integrated over segments of digital audio data upon receiving analysis triggers which can be synced with the audio tempo. The integrated spectrum is processed to find peak frequencies in the spectrum and their associated gain stored in a peaks array. The peak frequencies are used to program the oscillators controllable attributes and characteristics. The synthesis is performed upon receiving an analysis clock. A number of digital oscillators are configured with the associated frequency parameters and gain parameters from a peaks array. The oscillators are configured according to the audio pitch analysis and generate an oscillator output at the frequency and gain specified in the peaks array. These oscillator outputs are summed together generating synthesized audio.

Systems and methods for onboard, real-time pickup blending for electric guitars/basses may utilize every possible tonal combination that double coil pickups can offer. The industry standard pickup toggle switch may be removed from electric guitar/bass instruments. Instead of a user being limited to only using one pickup at a time to be selected, the user may mix in any combination of the pickups (top, bottom, or both) at any time. Accordingly, multiple pickups can be on at the same time and/or the user may blend in (or out) any percentage of any of the pickups that the user wishes to create a large combination of tones.

An audio processing method obtains observed envelopes of picked-up sound signals including a first observed envelope representing a contour of a first sound signal including a first target sound from a first sound source and a second spill sound from a second sound source and a second observed envelope representing a contour of a second sound signal including a second target sound from the second sound source and a first spill sound from the first sound source; and generates, based on the observed envelopes, output envelopes including a first output envelope representing a contour of the first target sound in the first observed envelope and a second output envelope representing a contour of the second target sound in the second observed envelope, using a mix matrix including a mix proportion of the second spill sound in the first sound signal and a mix proportion of the first spill sound in the second sound signal.

A device includes a guard structure configured to mount to a body of a guitar proximate a pickup selector lever of a pickup selector mechanism of the guitar. The guard structure includes a hood and when the guard structure is mounted to the body of the guitar over the pickup selector lever, the hood is oriented away from a pickup of the guitar. In an embodiment, when the guard structure is mounted to the body of the guitar at least a portion of the pickup selector lever is positioned within an interior volume of the hood of the guard structure.

A method for synchronizing an electronic interactive device on basis of a first sound track is provided. The method may include identifying a first peak point and a valley point of the first sound track by calculating a first energy of the first peak point and a first energy of the valley point of the first peak point and comparing the first energy of the first peak point with first energy of neighboring points of the first peak point. The method may also include identifying a first peak point of a second soundtrack, and determining a similarity between the first soundtrack and a second sound track on basis of the first peak point of the first soundtrack and the first peak point of the second sound track.
