so my question is if do that my sound quility is like aac format or the sound is losseless like aiff and wav file?
tnx

It is like the quality of the original file, so it would be like your AAC file. There is no point in up-converting a lower quality file unless it is to put it into a format required by an application you are using. You cannot get back the lost quality. Taking this a step farther, up-converting from a lossy format (AAC, mp3, etc.) to another lossy format will, in fact, result in even more loss since each conversion using a lossy format results in more loss. It's like making a photocopy of a photocopy of an original. In your case, converting to a lossless format would just result in a copy of the AAC file in the original quality of the AAC file, just in a lossless format. It would result in a possibly larger file but no better quality.
