Free from single software for mac

AIFF from PCM is a freeware tool to convert files containing stereo or mono linear PCM sound data into AIFF format.
To help visualize here is an example: You authored a DVD disk using iDVD a long time ago. The burned disk is still there but your original soundtrack is no more available. Although you can extract the sound data from the DVD using for example the excellent MacTheRipper or YadeX, this extracted file wont play.
The problem is that it will be extracted as PCM, which is a raw sound data missing any additional information. To play it, to import it into iTunes or to use it in iDVD again, the file has to be converted into another format. The file type most recommended to be converted to would be AIFF, and AIFF from PCM is a tool that can be of great help for this job.
