If the Paraliminal contains the Holosync Technology use the following as a guide.
It is not recommend to use compressed formats like mp3 for your Holosync/Autofonix soundtracks. Compression can diminish the effectiveness of some binaural beat technologies like Holosync.
You can copy your Holosync/Autofonix soundtracks to your iPod or other media device using the following audio file formats without losing effectiveness:
WAV
AIFF
FLAC
APE (Monkey's Audio)
SHN
Note that the above list includes commonly used lossless or uncompressed file formats. Your media player may support other formats not listed.
I use AIFF for my iPod and I have analyzed the audio results with no differences between the the original and copy..
Hope this helps
