6.3.5 EstimateLeak

6.3.5.1 Outline of the node

This node estimates a leakage component from the other channels.

6.3.5.2 Necessary files

No files are required.

6.3.5.3 Usage

When to use

This node is used for denoising after source separation with GHDSS .

Typical connection

Figure 6.49 shows a connection example of EstimateLeak . The input is a speech power spectrum output from GHDSS . The outputs are connected to CalcSpecAddPower .

6.3.5.4 Input-output and property of the node

Input

INPUT_POWER_SPEC

: Map<int, ObjectRef> type. Vector<float> type data pair of a sound source ID and power spectrum.

Output

LEAK_POWER_SPEC

: Map<int, ObjectRef> type. Vector<float> type data pair of a sound source ID and power spectrum of leakage noise.

Parameter
