Hi, I'm looking at the "cocktail party" classic problem. I can see how to use ICA to separate the components. But, How do I then create new wav files of the separated sounds so that they can be played?
Others suggested tuneR already for a former question. You can make a Wave object from the signal returned by ICA processing using tuneR and also write a wav filke with tuneR: See ?Wave and ?writeWave Best, Uwe Ligges

FWIW you can play sounds directly without creating any files using play() from the audio package. Cheers, Simon
