Interference Reduction on Full-Length Live Recordings

Diego Di Carlo, Antoine Liutkus, Ken Deguemel
2018 2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
Interference reduction with these ideas can be achieved on full-length live multi-track recordings in an acceptable time and could be used by sound engineers.  ...  Live concert recordings consist in long multitrack audio samples with significant interferences between channels. For audio engineering purposes, it is desirable to attenuate those interferences.  ...  Access to the Montreux Jazz Festival database was provided by EPFL, in the scope of DYCI2.  ...

Kernel Additive Modeling for interference reduction in multi-channel music recordings

Thomas Pratzlich, Rachel M. Bittner, Antoine Liutkus, Meinard Muller
2015 2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
In practice, each one contains interference from every other voice. In this paper, we aim to reduce these interferences in multi-channel recordings to recover only the isolated voices.  ...  When recording a live musical performance, the different voices, such as the instrument groups or soloists of an orchestra, are typically recorded in the same room simultaneously, with at least one microphone  ...  CONCLUSIONS In this paper, we have proposed a simple, yet effective algorithm called KAMIR for interference reduction in multi-channel live recordings.  ...

2018 Light: Science & Applications  
This review article provides a broad discussion about the noise issue in DH, with the aim of covering the best-performing noise reduction approaches that have been proposed so far.  ...  That is, a universal denoising strategy for completely suppressing holographic noise has not yet been established.  ...  Optical techniques for noise reduction in DH mainly involve the reduction of the light coherence, engineering the light sources in the recording stage, or recording multiple holograms of the same object  ...

Shift-Invariant Kernel Additive Modelling for Audio Source Separation [article]

Delia Fano Yela, Sebastian Ewert, Ken O'Hanlon, Mark B. Sandler
2018 arXiv   pre-print
This choice assumes that the source of interest repeats in both time and frequency. In practice, this assumption does not always hold.  ...  A major goal in blind source separation to identify and separate sources is to model their inherent characteristics.  ...  The proposed methods were evaluated in an interference reduction scenario for transient noise typically found on live and studio music recordings.  ...
