Hi. The following sentences are my estimation. If there really is a better way, of course I would also be very interested in how.
This is probably only possible with use an some external library because the audio CD format uses its own data format. They are basically WAV files but are not readable because CD-DA has one BYTE size of 14 bits, which is not compatible with the standard (8 bites per byte). With such a structure, the OPEN statement is computed, so CD-DA without special software is directly not accessible to QB64.
