Hey all, 'Timetraveller' here. Did not get chance to ask this on air as living in the UK I only get to listen once the program has aired.
Great show and remember these two guests years and years ago probably just before Art decided to run out of talent and fall off his antenna and hurt his back. One thing that was mentioned that did wonder was that Brendan mentioned that a smartphone can record EVPs but most smartphones (and a lot of digital recorders) compress the audio stream to mp3 and you loose so much in the audio spectrum. Would not a lossless (PCM) recording at say 96KHz not be best as then you could put it through something like adobe audition (or freeware Audacity) and then check the waveforms and possible start using some nice DSP filters to get a better chance of an EVP?
