I have received a few emails regarding the origin of lossless files as many here only use lossless for archiving and their main auido collections. So I figured I would just write this post to answer all the questions at once. If you encode your own files from your own CD, you know the origins but the trouble is some people are worried about the source of these files when they are not encoded by us. There is a program that has been out for awhile that checks the origin of APE, FLAC, SHN, WAV and LPAC files or audio CD tracks. The program is called Audiochecker, it tests your audio files and will tell you if they originated from CDDA (CD files) which is good or from a lossy source such as Mp3 which is bad! I figured this app would be appreciated by you guys that are unsure of the origins of your FLAC files. Being as busy as I am, I have only run quick tests but I know you can optimize the testing for larger collections, such as the app will check the smallest file in the album. You can also have the app put a test log in each album folder which is very handy. Granted, this app takes a bit of time considering what it actually does and you only have to do the test once to know. You can find it here:-> Audiochecker Beta Hopefully this will be of help to some of you that are worried about the source of some of your files. Comments?
