No. The InnaPeace technology is perfectly effective in an MP3 format.
Many lesser-quality 128 kbs MP3s are formatted with fairly high “compression”, which is not compression at all but “trimming” of the high and low tones to decrease the file size.
This is not the case with InnaPeace, which uses only better-than-CD-quality 320kbs, allowing for the complete range of tones.
This is the reason the demo track is less powerful than the main program tracks.
We chose to offer the InnaPeace program in the 320kbs MP3 format for ease of use, portability and exceptional sound quality, and to pass on significant cost savings to you.
