HTOA - Hidden Track One Audio
Some audio CDs we buy can have hidden audio within the first track of the disc. In order for some hi-fi CD
players to playback this audio you would start playing track 1 (at the beginning) and press the rewind
But when we come to back-up/transfer our audio CDs to the PC this hidden audio can become lost. This is
because not all PC CD/DVD Rom drives can successfully retrieve this audio. What we'd like
to do at daefeatures.co.uk
is to catalogue this functionality
along with the other drive features we already cover.
Thankfully, this feature is easy to test for. All you need is a CUE compliant burning app and the files
that are available here for download.

and not the .wav file when burning your disc!
Once the image has finished burning you can return to the main EAC

but that track should be in red. This means that there is a hidden track or TRACK 01 INDEX 00.
To extract the audio you should again use EAC
and use EAC

has finished it's job playback the
wav file in any audio player. If audio starts playing immediately your drive can retrieve the HTOA (or hidden
track one audio).
