Noise Extraction Parameters

This section references parameters of the noise algorithm.

Parameter

Description

Noise profile

The definition of a noise profile is mandatory for noise extraction. It can be defined using one of these four options:

  • From a WAV file: the noise profile is computed from the whole signal, which therefore should contain only noise. This noise should not change over time.

  • From Sound: Analysis and Specification: the noise profile is computed from a signal already open in Sound: Analysis and Specification.

  • Automatic estimation: the noise profile is automatically estimated from the input signal.

  • White noise: user has to give the noise RMS level (in dB SPL).

Gain

This parameter corresponds to the gain that is applied to the noise profile. This gain is immediately applied when defining it.

Temporal resolution

This parameter corresponds to the time domain resolution at which the noise signal should be considered stationary.
