Abstract

The present disclosure describes systems and methods for audio signal processing, and more specifically, techniques for automatically generating surround sound by extending stereo signals including a left and right channel to multi-channel formats in an unsupervised and content-independent or content-agnostic manner. In operation, a computing device may receive a stereo audio input signal containing two channels from a sound source. The computing device may transform the stereo audio input signal into an upmixed multi-channel time domain audio signal to create an immersive surround sound listening experience by wrapping the original stereo field to a higher number of speakers in the frequency domain. Based at least on the continuous mapping and the panning coefficient, the computing device may generate the upmixed multi-channel time domain audio signal.

• H04S 7/00 - Indicating arrangementsControl arrangements, e.g. balance control

Abstract

A signal processing method generates a time-frequency domain representation of an input signal for the purpose of signal detection, signal display, and application of filtering operations, such as sample accurate spectral editing. The method may include receiving an input signal in the time domain in a processor. The input signal may include a plurality of transform frames. The input signal is transformed into the frequency domain using a frequency transform. Time-frequency matrices are generated from the frequency transform. Crossfrequency phase coupling is applied between adjacent frequency bins to introduce synchronization between adjacent frequencies and to generate smoothed time-frequency matrices with sample-accurate frequency magnitudes. The frequency information can be edited in the time-frequency domain specific to a single sample of the transform frame to alter unwanted signal features. A modified time domain representation of the edited input signal can be generated from the modified time-frequency matrices.

Abstract

An audio file editing system enabling creation and editing of audio content within a single multi-layer audio file. The audio editor and method of the invention enables “layering” of audio content relative to other audio content within a single file to create a multi-layered audio file. This enables audio information to be combined in a way that keeps all content active and editable until the final product. An unlimited number of layers can be assembled within a file, constrained only by practical file size limits and system capabilities.
