1. Sample Rate
The sample rate is the digit of audio carried per second. A broader and higher range of sample rates leads to better sound and music quality. AAC is better than AC3 in this aspect.
Bitrate refers to the numbers or bits processed per second, minute, hour, or longer. A higher bitrate is associated with higher quality, which means a bigger file size. It is more commonly used in playback/streaming than in recording.
3. VBR (Variable Bitrate)
Variable Bitrate is a control technique that allows the bit rate to vary yet maintains the audio quality. It improves audio quality in contrast to the file size ratio, producing a better quality-to-space ratio on the same file size. AAC is more flexible than AC3.
Video and streaming audio application enables you to listen to or view music files. The more applications it supports, the better. This is because you can playback your audio on various platforms and devices.
In summary, AAC is better than AC3 in sample rate, bitrate, quality, and support for more platforms. The only thing that AC3 has the advantage of is backward compatibility with older Dolby equipment.
