The claim of novelty for time-travel filtering seems odd, so I wonder if this was a mistake in transcribing the quotation for the article. Any FIR filter can effectively time travel if you consider the peak to be time zero. Negative delay of one part of the sound is positive delay of the rest. It's not new to this article, but this is something that is new with DSP that is not so easy without DSP.
The DRC room correction software could achieve excellent results with frequency-dependent temporal correction back in the early/mid 2000s: http://drc-fir.sourceforge.net/ http://drc-fir.sourceforge.net/
