The present invention relates to the field of audio recognition, in particular to computer implemented note recognition methods in a gaming application. Furthermore, the present invention relates to improving latency of such audio recognition methods. One of the embodiments of the invention described herein is a method for note recognition of an audio source. The method includes: dividing an audio input into a plurality of frames, each frame having a pre-determined length, conducting a frequency analysis of at least a set of the plurality of frames, based on the frequency analysis, determining if a frame is a transient frame with a frequency change between the beginning and end of the frame, comparing the frequency analysis of each said transient frame to the frequency analysis of an immediately preceding frame and, based on said comparison, determining at least one probable pitch present at the end of each transient frame, and for each transient frame, outputting pitch data indicative of the probable pitch present at the end of the transient frame.

A sound control device includes: a reception unit that receives a start instruction indicating a start of output of a sound; a reading unit that reads a control parameter that determines an output mode of the sound, in response to the start instruction being received; and a control unit that causes the sound to be output in a mode according to the read control parameter.

A hi-hat cymbal sound generation apparatus according to the present invention includes an input part, a recording part, a trigger part and a sound volume control part. The input part acquires distance information on a distance between a top pad and a bottom pad, state information and vibration information on a vibration of the top pad. The input part acquires the state information by determining the state information based on a corrected distance, which is obtained by adding a distance correction value, which corresponds to a magnitude of the vibration indicated by the vibration information, to the distance indicated by the distance information. The recording part records data on a hit sound in each state indicated by the state information. The trigger part checks whether the vibration indicated by the vibration information falls within a predetermined range in which a sound generation procedure is to be started.

When an instruction is provided for changing a characteristic of a set filter which includes a plurality of partial filters and forms a specified characteristic by combining a plurality of partial filters, a processor performs, as crossfading processing for a first filter and a second filter among the plurality of partial filters, fade-out processing of gradually decreasing a degree of contribution of the first filter to the characteristic and fade-in processing of gradually increasing a degree of contribution of the second filter to the characteristic. As a result, unnaturalness occurring at the time of changing filter characteristics is solved.

A method and a device provides a user with the ability to freely improvise or play around with a selection of different chords and be provided with visual guidance assisting the improvisation of melody, while also providing accompaniment consistent with the selection of chords. Sound files consistent with a user selection of a chord and/or a dynamic level are selected from an audio library and played, while the user is given visual cues on a user interface keyboard assisting the user to select notes that are consistent with the chord selected for the accompaniment.

Provided are an audio file re-recording method and device, and a storage medium. The method includes: determining first time, the first time being start time of a recorded clip to be re-recorded in an audio file; playing a first recorded clip that has been recorded, the first recorded clip using the first time as end time in the audio file; upon arrival of the first time, collecting first voice data of a user to obtain a second recorded clip; and processing the first recorded clip and the second recorded clip to obtain a re-recorded audio file.

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.

An apparatus for analysing a magnitude spectrogram of an audio signal is provided. The apparatus includes a frequency change determiner being configured to determine a change of a frequency for each time-frequency bin of a plurality of time-frequency bins of the magnitude spectrogram of the audio signal depending on the magnitude spectrogram of the audio signal. Moreover, the apparatus includes a classifier being configured to assign each time-frequency bin of the plurality of time-frequency bins to a signal component group of two or more signal component groups depending on the change of the frequency determined for the time-frequency bin.

Described are apparatus for generating and/or processing audio signals. One apparatus includes: a first stage for obtaining an audio signal; a second stage for modifying the audio signal based on one or more control signals for shaping sound represented by the audio signal; a third stage for generating spatial metadata related to the modified audio signal, based at least in part on the one or more control signals; and an output stage for outputting the modified audio signal together with the generated spatial metadata. Also described are corresponding methods, as well as corresponding programs and computer-readable storage media.
