Described are methods and systems of identifying one or more fundamental frequency component(s) of an audio signal. The methods and systems may include any one or more of an audio event receiving step, a signal discretization step, a masking step, and/or a transcription step.

A method. The method including receiving a prompt describing desired characteristics of audio. The method further including generating, using a set of machine learning models and based on the prompt, a latent space representation of the audio at a latent rate less than 40 Hz. The method further including generating, using the set of machine learning models and the latent space representation of the audio, an audio file at an output rate greater than the latent rate. The audio file including the audio based on the latent space representation of the audio. The audio having a length greater than 90 seconds.
