- Rockin’ Patent: US Patent No. 10,068,557
- Filed: 23 August 2017
- In the name of: Google LLC
- Title: Generating Music With Deep Neural Networks
- What’s claimed: “A computer system to generate music, the computer system comprising: a machine-learned neural synthesizer model comprising an autoencoder model, the autoencoder model comprising an encoder neural network and a decoder neural network; wherein the encoder neural network is configured to receive an input audio waveform and, in response, provide an embedding descriptive of the input audio waveform; and wherein the decoder neural network is configured to receive the embedding and at least a portion of the input audio waveform and, in response, predict a next sequential audio sample for the input audio waveform; one or more processors; and one or more non-transitory computer readable media that collectively store instructions that, when executed by the one or more processors cause the computer system to perform operations, the operations comprising: evaluating a loss function that compares the next sequential audio sample predicted by the decoder neural network to a ground-truth audio sample associated with the input audio waveform; and adjusting one or more parameters of the autoencoder model to improve the loss function.”
- Why this patent rocks: This patent appears to involve Google LLC’s ‘NSynth’ (‘neural synthesiser’) project that uses a neural network to combine the sounds of different instruments to generate new, synthesised sounds. It has been suggested that NSynth algorithm learns the core mathematical aspects of each instrument’s sound waves and combines them to produce a new sound that is not simply the product of compiling those instruments on top of one another. Google LLC took the sounds from NSynth and used them to produce a musical instrument called ‘NSynth Super’.
