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

If you have the original lossless and a "suspect" file you can compare them. Based on the eventual differences you can pretty much certainly determine if the suspect is of lossless origin or not. (Not with 100% certainty, unless you know that there weren't any other lossless versions, like different pressings etc. or without taking into account ripping errors.)

If you only have the "suspect" file, you can never be sure of its origin. You can only make a guess with certain tools, like the spectrum analyzer, which will show you if there was a high frequency cut, which is typical for some lossy encodings.

PS: How do I upload Images here

Upload the picture to some image host (like Tinypic). Get the direct link to the picture and post it with the "Insert Image" button.
