System and method for customized heterodyning of collected sounds from electromechanical equipment
Systems and methods are disclosed herein for customized presentation of sound data associated with the operation of electromechanical equipment, wherein users of varying hearing capabilities can ascertain conditions of the equipment in real time. A sound detection device includes transducers which collect sound signals from the equipment and convert the sound signals into digital sound data. A processor generates a first audio data set corresponding to the digital sound data received from the sound detection device and, for a given human user, identifies an audio profile comprising perceivable audio frequency ranges. A target frequency range is identified within the perceivable audio frequency ranges for the given human user, and the first audio data set is shifted or mapped to the target frequency range to generate a second audio data set. Audio output signals corresponding to the second audio data set are user-selectively delivered to the user via an audio receiver.
Post filter for audio signals
In some embodiments, a pitch filter for filtering a preliminary audio signal generated from an audio bitstream is disclosed. The pitch filter has an operating mode selected from one of either: (i) an active mode where the preliminary audio signal is filtered using filtering information to obtain a filtered audio signal, and (ii) an inactive mode where the pitch filter is disabled. The preliminary audio signal is generated in an audio encoder or audio decoder having a coding mode selected from at least two distinct coding modes, and the pitch filter is capable of being selectively operated in either the active mode or the inactive mode while operating in the coding mode based on control information.

Singing voice conversion
A method, computer program, and computer system is provided for converting a singing first singing voice associated with a first speaker to a second singing voice associated with a second speaker. A context associated with one or more phonemes corresponding to the first singing voice is encoded, and the one or more phonemes are aligned to one or more target acoustic frames based on the encoded context. One or more mel-spectrogram features are recursively generated from the aligned phonemes and target acoustic frames, and a sample corresponding to the first singing voice is converted to a sample corresponding to the second singing voice using the generated mel-spectrogram features.
Machine-Learned Differentiable Digital Signal Processing
Systems and methods of the present disclosure are directed toward digital signal processing using machine-learned differentiable digital signal processors. For example, embodiments of the present disclosure may include differentiable digital signal processors within the training loop of a machine-learned model (e.g., for gradient-based training). Advantageously, systems and methods of the present disclosure provide high quality signal processing using smaller models than prior systems, thereby reducing energy costs (e.g., storage and/or processing costs) associated with performing digital signal processing.
Information processor, information processing method, and program
[Problem] To allow a user to grasp clearly a source of information with sound. [Solution] There is provided an information processor that includes an output control unit that controls output of an information notification using sound, the output control unit causing, on the basis of a recognized external sound source, the information notification to be output in an output mode that is not similar to an external sound that can be emitted by the external sound source. There is also provided an information processing method that includes controlling, by a processor, output of an information notification using sound, the controlling further including causing, on the basis of a recognized external sound source, the information notification to be output in an output mode that is not similar to an external sound that can be emitted by the external sound source.
Generating speech in the voice of a player of a video game
A computer-implemented method of generating speech audio in a video game is provided. The method includes inputting, into a synthesizer module, input data that represents speech content. Source acoustic features for the speech content in the voice of a source speaker are generated and are input, along with a speaker embedding associated with a player of the video game into an acoustic feature encoder of a voice convertor. One or more acoustic feature encodings are generated as output of the acoustic feature encoder, which are inputted into an acoustic feature decoder of the voice convertor to generate target acoustic features. The target acoustic features are processed with one or more modules, to generate speech audio in the voice of the player.
