If so, how? I don't want to listen to it from the computer. Thanks.

As long as you don't compress it or run it though a filter.

You can compress it as long as you keep the quality high. Mp3 compression only strips extreme high and low end frequencies, which you won't be able to hear anyways.

I've recently exported several 60 minute MAP preset patches. Export them as .wav files through BWgen, and then use a program to encode them to mp3 or desired format. I'm an audio engineer so I have access to wavelab, but you can find a free alternative on the internet. Use either high quality VBR or 320 kbps constant bit rate encoding for best results.

The point of binaural beats is for the brain to create the 'third tone' by subtracting the low from the high frequency. It doesn't matter if you hear it or not, the brain does process it. If you clean the highs and the lows you remove the binaural aspect, and you're no longer doing hemispheric synchronization, you're just listening to repetitive beats, which is not why you spent the money on binaurals.

The frequencies removed by a good quality mp3 compression, cannot be reproduced by consumer grade headphones. It's also important to note that every speaker, including headphones, has its own frequency curve which shapes the sound in different ways. This means every person will hear the sound differently. Most cheaper in-ear headphones won't even play frequencies below 100 Hz, and higher frequencies are quite distorted. Speakers will change the sound of any audio far far more than compression.

You're correct that the binaural beats are used to create a third tone. However we do not hear this third tone. It is interpreted by our brain. The human hearing range is only 20 Hz to 20 kHz, and binaural beats are below this. To get, say, a 4 Hz (delta) wave, we could play 150 Hz through left ear and 154 Hz through the right. Or 300 and 304. Or 425/429. All of these will create the delta wave for our brain, and all of them won't be affected in the least by a good quality compression. :-)

Yes you can if you not compress it.

To clear it up, once again... it is fine to compress the signal, as long as the quality settings are relatively high.

You can get the mp3's here: http://www.brianmercerbooks.com/MAPBrainwaveGeneratorMAP.html
