摘要： Systems and methods for processing an audio signal are provided for replay on an audio device. An audio signal is spectrally decomposed into a plurality of subband signals using band pass filters. Each of the subband signals are provided to a respective modulator and subsequently, from the modulator output, provided to a respective first processing path that includes a first dynamic range compressor, DRC. Each subband signal is feedforward compressed by the respective first DRC to obtain a feedforward-compressed subband signal, wherein the first DRC is slowed relative to an instantaneous DRC. Subsequently, each feedforward-compressed subband signal is provided to a second processing path that includes a second DRC, wherein the feedforward-compressed subband signal is compressed by the respective second DRC and outputted to the respective modulator. Modulation of the subband signals is then performed in dependence on the output of the second processing path. Finally, the feedforward-compressed subband signals are recombined.

摘要： The present disclosure provides a method and apparatus for correcting a delay between an accompaniment and an unaccompanied sound, and a storage medium, and belongs to the field of information processing technology. The method includes: acquiring accompaniment audio, unaccompanied sound audio and original song audio of a target song, and extracting original song vocal audio from the original song audio; determining a first correlation function curve based on the original song vocal audio and the unaccompanied sound audio, and determining a second correlation function curve based on the original song audio and the accompaniment audio; and correcting a delay between the accompaniment audio and the unaccompanied sound audio based on the first correlation function curve and the second correlation function curve. It can be seen therefrom that in the embodiment of the present disclosure, by processing the accompaniment audio, the unaccompanied sound audio and the corresponding original song audio, the delay between the accompaniment audio and the unaccompanied sound audio is corrected. Compared with the method for correction by a worker at present, this method saves both labors and time and improves the correction efficiency and also eliminates correction mistakes possibly caused by human factors, thereby improving the accuracy.

摘要： The inventions relate to the field of electric musical instruments, more particularly, to an optical sensor for a stringed musical instrument with a digital interface and to a stringed musical instrument with a digital interface equipped with said sensor (MIDI - Musical Instrument Digital Interface).
Implementation of the disclosed inventions allows to obtain a signal corresponding to vibrations (deflections) of a string in two mutually perpendicular planes, with the influence of the device generating such signals on string vibration parameters being reduced, without signals generated by different strings being mixed and with dimensions of the optical sensor being reduced to allow for its compact placement on a stringed musical instrument.-

摘要： The present disclosure discloses an audio signal processing method and apparatus, and a storage medium and belongs to the field of terminal technologies. The audio signal processing method includes: acquiring a first audio signal of a target song sung by a user; extracting timbre information of the user from the first audio signal; acquiring intonation information of a standard audio signal of the target song; and generating a second audio signal of the target song based on the timbre information and the intonation information. Since the second audio signal of the target song is generated based on the timbre information of the standard audio signal and the intonation information of the user, even if the user's singing skills are poor, a high-quality audio signal may still be generated. Thus, the quality of the generated audio signal is improved.

摘要： A low-cost and high-compatibility optical pickup including a light source, one set of optical sensors, and a controller. The light source illuminates a string assembled on an instrument. The set of optical sensors corresponding to the light source is provided to sense the shading of the string. The controller supplies the sensed data from the set of optical sensors to a system host for recognition of the melody played on the string. Considering the other strings assembled on the instrument, the optical pickup includes other sets of optical sensors to sense the shading of the other strings which are also illuminated by the light source. The controller also supplies the sensed data of the other sets of optical sensors to the system host for recognition of the melody played on the other strings.
