About the AAC format
AAC (Advanced Audio Coding)
AAC was standardised in 1997 in MPEG-2 and later in MPEG-4. It usually sits inside M4A and MP4 - that's how Apple Music tracks and the sound of most videos are stored. An .aac file is a stream without a container: internet radio recordings and sound extracted from video are saved this way.
Some players, car stereos and programs can't open .aac files. Then they are converted to MP3 at a bitrate no lower than the source, or to WAV for audio editors: WAV adds no new loss but takes several times more space.
Best for music and video soundtracks at a small file size.
