Quality Loss When Converting MP3 to AAC Using iTunes or FFMPEG
Many music files are encoded with the Advanced Audio Coding (AAC) that can reduce the size of the file. Audios in AAC format are of smaller size but of comparatively good quality. Additionally, it is compatible with many popular players and devices, such as iPhone. However, users may be anxious about the loss of quality when they want to convert MP3 to AAC format.
Some users may directly use iTunes as audio converter. But according to some users, "iTunes will covert audio but at a loss of quality. I thought that by putting the songs on a CD and ripping from the loss of quality will not be severe."
Similarly, some feel hassled as well when converting MP3 to AAC with audio converters such as ffmpeg. "The problem here is: ffmpeg obviously can't convert to a higher bitrate than 152k. Even when it says it does so the resulting files still have 152k instead of 192k...."
Since we need to obtain the lossless audios in AAC format, not all of the audio converters can do this. It is noted that the conversion between MP3 and AAC is closely related to the process of decoding and re-encoding during which loss of quality certainly happens.
