Hi Doug

 
By SoulSearcher at February 14, 2007 - 3:12pm | Ask Doug

I was listening to a old archived show and it mentioned that you use a MP3 to record EVPs. I wondered if you have had any luck using the MP3? I asked this same question on the TAPS message board and only recieved one reply saying probably not due to frequencies. I have not purchased a digital voice recorder yet but I do have a IRiver MP3 that records so I thought I would give it a shot first before I go the voice recorder route.

MP3 recording

By Doug on March 18, 2007 - 12:50am

An open source reference implementation of the MP3 encoding algorithm (called LAME) does indeed engage hipass filtering by default. Which means very low frequencies are not encoded into the recording. Other encoders may or may not follow that example, and that example is a default that can be adjusted or even disabled.

However, most folks analyzing audio for EVPs do not seem to pull out only the low frequencies and then adjust them up to the audible range for listening. Most folks appear to listen to the audio and should they hear anything (which implies the EVP exists within the audible frequencies) they then go through bizarre and different-for-every-person mechanations to do whatever they consider it is to "clean up" the interesting snippet.

I've only ever seen one show on TV where the fellow said he was transforming the sub-audible frequencies into audible frequencies for analysis of the sub-audible spectrum. And I've never actually met anyone who claims to do that.

That being said, I don't believe that the hipass filter that may be within your MP3 encoder will stop you from recording EVPs in the audible range--which is exactly what everyone seems to be looking for with one single exception (the guy in the TV show mentioned above).

So go for it!

And my luck at capturing EVPs is dismal no matter what recorder I use. Sadly, that includes my MP3 recorder.
