Technique and mechanism for processing polyphonic audio signals. Processing includes filtering the audio signals to generate a set of narrow band signals, estimating an instantaneous magnitude and frequency associated with the narrow band signals and driving a bank of sinusoidal oscillators based on the instantaneous magnitude and frequency to create an output audio signal.
A musical synthesizer produces an audio signal using a set including hundreds or thousands of resonators. The resonators can be based on analysis of any acoustic space such as an acoustic instrument, room, studio, or concert hall A machine learning network is trained to learn the characteristics of a musical sound. The characteristic may be whether the sound is pleasing to the human ear. The network produces audio effects applied to selected frequencies in the spectrum. An input or excitation signal is provided to the network, which processes the input through a trained model of a target audio source and configures the set of resonators to produce an output audio signal based on the input signal. The network may be expanded to create novel impulse responses creating tones and timbre unique to existing audio sources, the input signal may include musical tones or include vocal inputs.

The present disclosure provides systems and methods by which music can be created and played by automatically defining a set of pitches that can be selected based on interval changes for pitch values within the set. A set of available pitches within a particular series can be referred to as a pitch palette, wherein each available pitch within the pitch palette is associated with being some predefined interval from any other pitch within the pitch palette. In accordance with aspects of the disclosure, a device may be configured to automatically identify particular pitch palettes that correspond with certain pitches or with particular pieces of music.

Methods and systems for performing modal reverb techniques for audio signals are described. The method may involve simplifying a reverb effect to be applied to the audio signal by receiving an IR, dividing the IR into a plurality of sub-bands, using a parametric estimation algorithm to determine respective parameters of the modes included in each sub-band, aggregating the respective modes of the sub-bands into a set; and truncating the set of aggregated modes into a subset of modes. Reverberation of the audio signal may be manipulated based on an IR that itself is based on the truncated subset of modes.

Methods and systems for performing modified reverb techniques for audio signals are described. The method may involve receiving an audio signal, a modal reverb effect to be applied to the audio signal, and an indication of a plurality of frequencies. Modes of vibration of a space simulated by the reverb effect may be separated into a set of frequencies included in the input, and a set frequencies not included in the input. The modal reverb effect may be modified by separately adjusting the separate sets of modes of vibration. The modified effect may then be applied to the audio signal.
