AAC vs MP3
AAC and MP3 compared: both are lossy, and AAC is the newer of the two.
| Detail | AAC compared with MP3 |
|---|---|
| Age | MP3 dates from the early 1990s. AAC came in 1997, made to follow it. |
| Quality | At the same bitrate, AAC usually sounds a little better. At 192 kbps both are fine for most music. |
| Files | Raw AAC files end in .aac and have no container. Most AAC sound sits in M4A or MP4 files. |
| Device support | Phones, Apple devices, and current browsers play AAC. Some car stereos, old MP3 players, and upload forms take only MP3. |
| Size per minute | AAC at 128 kbps and MP3 at 128 kbps are the same size, about 1 MB per minute. The bitrate sets the size, not the format. |
| Conversion | AAC to MP3 is lossy to lossy. Use Standard or High so the second step loses little. |
