Methods and systems for improved neural beat generation for digital audio files are provided. In one embodiment the method is provided that includes receiving a digital audio file and a beat frequency for a neural beat. Chromagram features may be extracted from the digital audio file and may be used to identify dominant pitch classes at a plurality of timestamps within the digital audio file. A plurality of carrier frequencies at different time periods within the digital audio file may be selected based on the dominant pitch classes. A neural beat may be synthesized for the digital audio file based on the beat frequency in the plurality of carrier frequencies. The neural beat may be stored and/or may be combined with the digital audio file to generate a combined audio track, which may be stored.

The present invention provides a method for processing audio data, comprising the steps of providing input audio data containing a mixture of audio data including first audio data of a first musical timbre and second audio data of a second musical timbre different from said first musical timbre, decomposing the input audio data to provide decomposed data representative of the first audio data, transforming the decomposed data to obtain third audio data.

The invention generates progressive music in real-time for video games using random, seeded random, and manually input variables to affect melody, phrase length, harmonic chords and complexity, and percussive accompaniment. As the game is played, variables may be passed in that change the music to increase or decrease complexity and tension levels and to interpolate between styles. The generated music then progresses from stable, simple, and consonant to more tense, dissonant, and complex melodies, harmonies and rhythms, and back to the original stage as a musical resolution. Through variables controlling musical parameters, music may progressively change from the atonal region where there is no clear resolution or stability, to tonal, where there is only consonance and stability, and anywhere in between. These variables are assigned through a middleware or a game-engine setup that uses the current device as an audio source plugin, or manually coded into the individual video game.

Provided is a musical instrument controller capable of accurately controlling a musical sound parameter. This musical instrument controller includes: a reception means for receiving, from a musical performance device, a sound emission start signal transmitted on the basis of a musical performance operation; a sensor for detecting an amount of displacement from a reference position; and a control means for generating a control signal on the basis of the amount of displacement from the reference position and transmitting the control signal to a sound generation device. The control means sets the reference position on the basis of the sound emission start signal received from the musical performance device.

A method for generating an audio output is described. Image inputs of interactive movements by a user captured by an image sensor are received. The interactive movements are mapped to a sequence of audio element identifiers. The sequence of audio element identifiers are processed to generate a musical sequence by performing music theory rule enforcement on the sequence of audio element identifiers. An audio output that represents the musical sequence is generated.

The present disclosure relates to a method of automatically preparing a MIDI file based on a target MIDI file comprising respective note information about each of a plurality of target notes and a source MIDI file comprising respective note information about each of a plurality of source notes. Each note information comprises pitch information defining a pitch of the note. The method comprises ranking the plurality of target notes based on the pitch of each target note. The method also comprises, for each of the ranked target notes, removing the pitch information from the note information of the target note. The method also comprises, for each of the ranked target notes, replacing the removed pitch information with pitch information of a corresponding source note, whereby the target note has the same pitch as the corresponding source note, forming a plurality of new notes of a new MIDI file.

A method in accord with certain implementations involves, at a data interface of a musical instrument effects processor, receiving an extracted characteristic of an audible sound that is captured at a microphone; transferring the extracted characteristic to a digital signal processor residing in the musical instrument effects processor; receiving input signals at an input to the musical instrument effects processor; at the digital signal processor of the musical instrument effects processor, modifying the received input signals using the extracted characteristics to create the electronic audio effect; and outputting the modified input signals as an output signal from the musical instrument effects processor. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

A method for processing music audio data, including providing input audio data representing a first piece of music comprising a mixture of musical timbres. The method also includes decomposing the input audio data to generate at least first-timbre decomposed data representing a first timbre selected from the musical timbres of the first piece of music, and second-timbre decomposed data representing a second timbre selected from the musical timbres of the first piece of music. The method also includes applying a transport control to obtain transport controlled first-timbre decomposed data. The method also includes recombining audio data obtained from the transport controlled first-timbre decomposed data with audio data obtained from the second-timbre decomposed data to obtain recombined audio data.

A recommendation of at least one of multiple audio samples or sets of audio samples to combine with a particular audio sample or set of audio samples is automatically generated. The recommendation is generated by determining the rhythmic compatibility as well as the harmonic compatibility of the particular audio sample or set of samples with each of the multiple audio samples or sets of audio samples. For each of the multiple audio samples or sets of audio samples, a compatibility rating is generated based on the rhythmic compatibility and the harmonic compatibility of the audio sample or set of audio samples with the particular audio sample or set of audio samples. At least one of the multiple audio samples or sets of audio samples is presented by a computing device as a recommendation to combine with the particular audio sample or set of audio samples.

A content control device includes: a plurality of controls to which a plurality of parameters for controlling properties of a content containing at least one of sound and video are respectively assigned, each of the plurality of controls outputting a first indicated value in accordance with an operation amount of the control; and a processor configured to previously create setting information used to determine respective values of the plurality of parameters in accordance with the second indicated value; determine the values of the plurality of parameters corresponding to the second indicated value respectively in accordance with the second indicated value and the setting information; and revise each of the values of the parameters to be determined in accordance with the first indicated value outputted for the control assigned to the parameter.
