Converting AAC to MP3: what to know
AAC is an audio format often used for internet radio recordings, sound extracted from videos and tracks downloaded from websites. It is converted to MP3 for older players, car stereos and programs that don't open files with the .aac extension.
Both formats are lossy, so a little quality is lost in the conversion. To keep the loss inaudible, choose a bitrate no lower than the original: for music, 192–320 kbps.
AAC or MP3: which to choose?
AAC (Advanced Audio Coding)
AAC is a lossy audio format and the successor of MP3: it sounds better at the same bitrate.
Best for music and video soundtracks at a small file size.
MP3 (MPEG-1 Audio Layer III)
MP3 is the most universal audio format: compact files that play anywhere.
Best for music, podcasts and audiobooks on any device.
What happens when converting AAC to MP3

Trim the fragment, convert stereo to mono or change the sample rate.
AAC files up to 512 MB are supported; the actual limit also depends on the free memory of your device.
