Hi list, I would really like to see support for .cda as input files. The cda format is the one used on regular audio CDs. Support for this format would make it even easier to encode to FLAC from CDs -- Daniel Aleksandersen
You are mistaken, Daniel. Regular audio CDs do not use any kind of "file format" CDDA consists of a stream of audio data with metadata codes in a bitstream - there are no files, only a continuous stream of bits, frames, blocks, etc. The .cda files that you see are created by converting the raw CDDA data to a file - they are not to be confused with the original. The FLAC command-line conversion utility supports "raw" input, which is the closest thing to regular audio CD format that you can get.

However when you put an audio CD in a computer you will see them as files with the .cda extension. Supporting this ?format? would make encoding simpler as users would not need to ?rip? to a format, but could drag and drop the files from the CD to the computer. -- Daniel Aleksandersen
CDA is not a file format. It's just a "shortcut" in windows. CD Ripping requires device-level SCSI communications via the Device Driver API (DeviceIoControl) and is way out of the scope of FLAC. Use Exact Audio Copy or another ripping program to do this. Daniel Aleksandersen wrote:> Hi list, > > I would really like to see support for .cda as input files.

does anybody know why dvd use files for audio and video but audio cd's not? What could be the reason for this? e.g. they could make a file for each track and just put them on an audio cd and make cd players compatible with this format. So for me it has always been a mystery why audio cd's work this way. does anybody knows if super audio cd's still work the same as normal ones? 2007/9/13, Josh Coalson <xflac@yahoo.com>:> --- Daniel Aleksandersen <aleksandersen+xiphlists@runbox.com> wrote: > > > Hi list, > > > > I would really like to see support for .cda as input files.
