Why don't you show us the command you're using to try and create your CD? That might help us help you practically, rather than theoretically. To answer your questions: tao is track at once, as opposed to disk at once. It's what you get with the cdrecord -audio option. I mistyped and confused you. I was asking whether you really mean to create an audio CD, such as you might play in your stereo? Or do you really mean to put .wav or mp3 files on a CD ROM? It's not the same thing. Lastly, it's not copying in this case. Here's a brief extract from the cdrecord man page. Notice that it speaks of "extracting data" from the .wav file: If a filename ends in .au or .wav the file is considered to be a structured audio data file. Cdrecord assumes that the file in this case is a Sun audio file or a Microsoft .WAV file and extracts the audio data from the files by skipping over the non- audio header information. In all other cases, cdrecord will only work correctly if the audio data stream does not have any header. Because many structured audio files do not have an integral number of blocks (1/75th second) in length, it is often necessary to specify the -pad option as well. cdrecord recognizes that audio data in a .WAV file is stored in Intel (little- endian) byte order, and will automatically byte-swap the data if the CD recorder requires big-endian data.
