Hey,

I would like to ask a question about lossless audio. How can you distinguish between a lossless song and one which has just been converted into a lossless format but isnít actually lossless.

From what I understand you have to use a spectrum analyzer, but that is the extent of what I understand.

Thank you so much in advance wink.gif

(1) You cannot be completely sure. You can in quite a few cases verify that this hasn't been converted directly from a certain format to, say WAV without intermediate processing though.

(2) There are a few steps you can take in order to be more confident that the file is one way or the other.

(3) If you search this forum, you will find many old threads giving answers to (2) above. The most common answer is 'buy the CD and rip it yourself instead of pirating the track off the internet'.

Besides visual analysis, additional pointers: AuCDtect, TAU Analyzer, etc.

But more so, this. Or even, perhaps, if you ask me(!), just forget about lossless and buy a lossy file from a digital distributor without pointlessly buying a CD, ripping it, and then leaving it on a shelf for however many decades before it gets landfilled. lalala.gif
