I know you may not agree with what i say but as far as i know i do not think you can export as an mp3, and because they are at specific frequencies they would not properly work if you were to record them using another recording source, if i was you i would just work on lucid dreaming without the aid of the BrainWave Generator, it has worked for some but i have seen many people say it doesn't work, i see it more of a placebo, if people believe it will work it will work, just try to lucid dream without it, you don't want to have to depend on BrainWave Generator to induce lucid dreams, you want to be able to do things yourself and rely on only yourself. However thats only a suggestion, go ahead and use it if you like, but i'm not aware of there being any way of exporting the audio file, even if you recorded it the frequency would most likely get distorted simply by being recorded. Hope that helped you out
