Audio Signal Separation addresses the problem of segregating certain signals from an audio mixture. Focusing on the separation of musical audio signals, we addressed this problem from different angles in the context of several public and industrial research projects. Listen to some demo sounds in DEMOS tab. Orchestral music signals separation. We investigate the …
Blind Audio Source Separation: State-of-Art

The authors propose in this work a new algorithm for the separation of acoustic signals in a system with one input and multiple outputs. The input is a single source and the outputs are its transmitted signals observed at multiple microphones. The algorithm is composed of (L − 1) principal component

Improved Expectation-Maximization Algorithm for Unknown Reverberant Audio-Source Separation The problem of undecided Separating reverberant audio sources is crucial for speech and audio processing. Numerous separation strategies have been developed to solve this problem; however, all of them estimate model parameters in the time–frequency domain, …

Formally known as Audio Source S e paration, the problem we are trying to solve here consists in recovering or reconstructing one or more source signals that, through some -linear or convolutive-process, have been mixed with other signals. The field has many practical applications including but not limited to speech denoising and enhancement, music remixing, …
