Interference Reduction on Full-Length Live Recordings
2018
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Preserved Fulltext
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. ...

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. ...

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 ...
