摘要： Methods, systems, and computer program products for network-based processing and distribution of multimedia content of a live performance are disclosed. In some implementations, recording devices can be configured to record a multimedia event (e.g., a musical performance). The recording devices can provide the recordings to a server while the event is ongoing. The server automatically synchronizes, mixes and masters the recordings. The server performs the automatic mixing and mastering using reference audio data previously captured during a rehearsal. The server streams the mastered recording to multiple end users through the Internet or other public or private network. The streaming can be live streaming.

摘要： A sound signal synthesis method includes inputting control data representing conditions of a sound signal into a neural network, and thereby estimating first data representing a deterministic component of the sound signal and second data representing a stochastic component of the sound signal, and combining the deterministic component represented by the first data and the stochastic component represented by the second data, and thereby generating the sound signal. The neural network has learned a relationship between control data that represents conditions of a sound signal of a reference signal, a deterministic component of the sound signal of the reference signal, and a stochastic component of the sound signal of the reference signal.

摘要： A system and method for operating and performing a remotely networked virtual musical instrument. A client transmits musical control data to a remote server over the network, encompassing a digital music engine and digitally sampled virtual musical instruments. In return, the client consumes, synchronizes, and mixes the combined server playback stream from the network of the fully expressive and interactive musical performance with zero audible latency.

摘要： Disclosed herein are a number of example embodiments for an improved audio sample playback unit. For example, multi-dimensional mapping of triggers to audio samples is disclosed. Also disclosed is low latency retrieval and playback of audio samples via pre-loading of sample heads into high speed memory. Furthermore, disclosed herein is a multi-threaded control operation for generating audio frames in response to trigger inputs, as well as the use of multiple pipes from which audio data can be generated. Further still, an example embodiment provides for multi-level control of audio properties, including voice-specific controls, pipe-specific controls, and global controls.
