Abstract: Example aspects include techniques for implementing real-time and low-latency synthesis of audio. These techniques may include generating a frame by sampling audio input in increments equal to a buffer size of until a threshold corresponding to a frame size used to train a machine learning (ML) model is reached, detecting feature information within the frame, determining, by the ML model, control information for audio reproduction based on the feature information. In addition, the techniques may include generating filtered noise information by inverting the noise magnitude control information using an overlap and add technique, generating, based on the control information, additive harmonic information by combining a plurality of scaled wavetables, and rendering audio output based on the filtered noise information and the additive harmonic information.

Abstract: A method for SiC high-speed growth by regulating growth monomers using chemical potential under a non-equilibrium condition. The method uses a C-rich process (Si/H2=0.97‰, C/Si=1.55) to achieve a rapid growth of an epitaxial layer. When a relative chemical potential ?C of the C source in a growth atmosphere is high, growth monomers adsorbed in advance are SiC molecules in an epitaxial growth, and a height of a growth step is maintained at 1/2 c or 1 c. A rapid growth of the epitaxial growth is achieved, and a better surface roughness and a lower ionized doping concentration are obtained at the same time.

Abstract: Provided is a method for determining insulation thermomechanical deterioration of a VPI wire rod of a pumped storage power generator motor. The method includes: periodically performing a cold-heat cycling test on a wire rod, and performing an insulation dielectric dissipation factor testing and a result interpretation of the insulation dielectric dissipation factor testing before and after each period to obtain corresponding data; in response to determining the interpretation result as the data being qualified, continuing to perform the cold-heat cycling test; and in response to determining the interpretation result as the data being unqualified, striking the wire rod with a copper hammer, and using an acoustic acquisition and analysis system to perform signal processing to determine spectral characteristics in a thermomechanical deterioration state as a deterioration criterion.

Abstract: In examples, a method for generating a remixed audio sample is provided. The method may include receiving an audio portion, obtaining metadata from the received audio portion, and analyzing the metadata and generating a symbolic music representation based on the analyzed metadata. In some examples, a selection of a style asset is received and applied to the symbolic music representation. Accordingly, a remixed audio portion may be rendered based on the stylized symbolic representation. That is, metadata associated with a song or song portion may be analyzed to identify a tempo, key, structure, chord, and/or progressions, etc., such that a remixed version of the song can be provided with customized instrumental arrangements and styles.

Abstract: Systems and methods directed to combining audio tracks are provided. More specifically, a first audio track and a second audio track are received. The first audio track is separated into a vocal component and one or more accompaniment components. The second audio track is separated into a vocal component and one or more accompaniment components. A structure of the first audio track and a structure of the second audio track are determined. The first audio track and the second audio track are aligned based on the determined structures of the tracks. The vocal component of the first audio track is stretched to match a tempo of the second audio track. The stretched vocal component of the first audio track is added to the one or more accompaniment components of the second audio track.
