Modern headunits and even factory systems now support MP3 formats for playback. Our original Nero Audio CD image is still available and still the prefered format, but we're now pleased to offer for download all the original tracks in MP3 format ISO image.
The new disk includes a number of frequency sweeps as well, in 10hz bandwidths, and a 15hz bandwidth between 45 & 60hz.
1. Download the compressed file here (supplied in Zip format, compatible with all versions of Windows)
2. Open the file in Windows Explorer.
3. Double Click the image file (CD_MP3_TestTone_Image.iso) to start the burning routine.
NB: If you have problems burning the image using Windows, we recommend installing InfraRecorder, which is a free downloadable CD burning application.
