Directional Multi-slope SRIR De-Noising

Reverberation de-noising for spherical harmonic (SH) spatial / directional room impulse responses (SRIRs / DRIRs).

The proposed method utilizes a directional (multi-slope) parameterization of the reverberation tail and replaces parts that are estimated to be dominated by noise.

More information can be found in the publication http://dx.doi.org/10.17743/jaes.2022.0017

Quickstart by having a look at the DEMO_* script.

First, clone and checkout the git repository and its submodule git submodule update --init --recursive After this, the submodule 'DecayFitNet' should be at commit '33a5a546'.

Please make sure to meet the dependencies/requirements of the submodule DecayFitNet.


From this room impulse response with directional energy: DirRMS

To this directional EDC estimation and restoration (i.e. denoising): DirEDC

Resulting in a denoised output: EnInOut
