Abstract
Systems and methods to automatically equalize coloration in speech recordings is provided. In example embodiments, a reference spectral shape based on a reference signal is determined. An estimated spectral shape for an input signal is derived. Using the estimated spectral shape and the reference spectral shape a comparison is performed to determine gain settings. The gain settings comprise a gain value for each filter of a filter system. Using gain values associated with the gain setting, automatic equalization is performed on the input signal.

A method comprising:
- defining a reference spectral shape based on a reference signal;
- deriving an estimated spectral shape for an input signal;
- comparing, using one or more processors, the estimated spectral shape to the reference spectral shape to determine gain settings, the gain settings comprising a gain value for each filter of a filter system;
- and
- automatically performing equalization on the input signal using gain values associated with the gain setting.
A system comprising:
- a reference model module configured to define a reference spectral shape based on a reference signal;
- an input model module configured to derive an estimated spectral shape for an input signal;
- a comparison module configured to compare, using one or more processors, the estimated spectral shape to the reference spectral shape to determine gain settings, the gain settings comprising a gain value for each filter of a filter system;
- and
- a filter system configured to automatically perform equalization on the input signal using gain values associated with the gain setting.
A non-transitory machine-readable storage medium in communication with at least one processor, the machine-readable storage medium storing instructions which, when executed by the at least one processor, performs a method comprising:
- defining a reference spectral shape based on a reference signal;
- deriving an estimated spectral shape for an input signal;
- comparing, using one or more processors, the estimated spectral shape to the reference spectral shape to determine gain settings, the gain settings comprising a gain value for each filter of a filter system;
- and
- automatically performing equalization on the input signal using gain values associated with the gain setting.
