Speech separation with voice identity
Published:
We usually claim that audio-visual methods performs better than audio-only in blind sound source separation. We are gonna check the performance of audio-only methods by doing a simple experiment. To code a U-Net to perform source separation using identiy embeddings.
Masks in sound source separation: An ablation
Published:
In this blogpost I explain how masking works in sound source separation. It adresses binary mask and complex masks. An ablation study on their performance for the two-sources case is carried out.

Goal: Audio-visual sound source separation
Library: MIR Eval library ported to pytorch
Published:
I’ve ported MIR eval library to PyTorch enabling a faster evaluation.
It’s is available here –> torch_mir_eval
- Only the Source separation functions has been ported, even though the project is opensource and open to grow.

Let’s show how to preprocess audio data to be used in Deep Learning. To do so we are going to use two very standard libraries. numpy and librosa.

Resume EN: This project proposes a method for the task of audio source separation of a signal, based on the movements of the players related to that signal. The process is composed of three blocks. The first block, computes a frequential analysis of the original signal by Non- negative Matrix Factorization (NMF). The video processing block estimates the velocity signal of the movements of each player by two types of video segmentation: the first one is based on motion trajectories of the objects in the scene, while the second one, uses optical flow and Principal Component Analysis. The last processing block makes a cor- relation between the frequential information and the velocity signals, using four variation of a method based on NMF and Non-Negative Least Squares. Finally, some experiments show the efficacy of the different variants of the audio source separation method.
