Embodiment apparatus and associated methods relate to adapting an actuator to adjust the tension of a musical instrument string, configuring a sensor to detect vibration propagated through the musical instrument body, configuring a noise removal filter to remove an undesired signal from vibration propagated through the musical instrument body, and automatically tuning the musical instrument based on adjusting the musical instrument string tension by the actuator while removing the undesired signal, until the fundamental frequency propagated through the instrument body by the vibration of the musical instrument string is within a predetermined tolerance of a reference frequency. In an illustrative example, the undesired signal may be actuator vibration. In some embodiments, actuator vibration spectral content may vary as a function of actuator torque, and, the noise removal filter may be adapted in real time. Various examples may advantageously provide faster and more accurate stringed musical instrument tuning.

A sonification system and method for providing continuous monitoring of complex data metrics, such as that from computer system activity, by taking data from multiple streams and reducing each stream of data into an easily understood audio signal that is easily distinguishable from other audio signals generated from other data streams. The sonification system and method operates to map multi-dimensional data graphs to audio and consists largely of silence, separated by terse and informative audio signals which each provide information related to intensity measurements and quantity measurements during a predetermined time interval.

An electronic apparatus is disclosed, which includes an input interface configured to receive an audio signal, a processor configured to process the received audio signal, and an output interface configured to output the processed audio signal, in which the processor is configured to obtain a scale of a first octave by applying a filter bank to the audio signal based on a sampling frequency of the audio signal; down-sample the audio signal; and obtain a scale of a second octave lower than the first octave by applying the filter bank to the down-sampled signal.

Digital signal processing and machine learning techniques can be employed in a vocal capture and performance social network to computationally generate vocal pitch tracks from a collection of vocal performances captured against a common temporal baseline such as a backing track or an original performance by a popularizing artist. In this way, crowd-sourced pitch tracks may be generated and distributed for use in subsequent karaoke-style vocal audio captures or other applications. Large numbers of performances of a song can be used to generate a pitch track. Computationally determined pitch trackings from individual audio signal encodings of the crowd-sourced vocal performance set are aggregated and processed as an observation sequence of a trained Hidden Markov Model (HMM) or other statistical model to produce an output pitch track.

Embodiments of the present disclosure provide a harmony processing method and apparatus, a device, and a medium, and the method includes: acquiring a harmonic interval corresponding to a target harmony control in response to a triggering operation on the target harmony control; performing, according to the harmonic interval, sound modification processing on a first sound input originally to obtain a second sound, in which an interval between the first sound and the second sound is the harmonic interval; and generating a target audio according to the first sound and the second sound, wherein the first sound and the second sound are presented as different harmonic parts in the target audio.
