Acoustic Parameter Estimation

Contact: Richard Hendriks

Noise reduction and speech enhancement algorithms usually rely on acoustic parameters such as the acoustic transfer functions (ATFs) and power spectral densities (PSDs) of different sources. These parameters depend on the acoustic scene and usually have to be estimated in real-time. Below is a list of different estimator implementations.
