How can I import files from compact discs?
« on: June 04, 2008, 03:11:23 »
I would like to look at the waveforms of music files on compact discs. But every time I try to import the files, Sonic Vizualizer says that the format is not recognized. The file extension on a music file on a compact disc is .cda.  How do I look at these files?

Thanks.

As I understand it, a .cda file does not actually contain any audio data -- it's just an index that tells the computer where to read the music from the CD.  There is nothing in it for Sonic Visualiser to read (unless SV were to include code for direct access to CD drives, which it does not; it just loads files from the filesystem).

You need to use a CD ripper program to read the audio data from the CD and encode it into a file in a format that SV can load, such as WAV.

Thanks Chris. Any suggestions as to a good CD ripper program that would work?
