It is a successor to the MP3 format, offers better sound quality as compared to MP3 and is authorized by the ISO and IEC. AC3 is a commonly used file extension for the audio files played on DVDs. The AC3 is a common format for Dolby Digital audio on Blue-Ray and DVD.

|What is AC3/AAC||AC3 (Audio Coding) is nothing but Dolby Digital audio codec and the compression for this is lossy as well, except for the Dolby TrueHD. It is the common version which contains up to six channels of audio.|
|History||AAC was developed as a joint project by Dolby Laboratories, Sony Corporation, AAC, Nokia, AT&T Laboratories and Fraunhofer IIS as an international standard, as a product of the Moving Picture Experts Group. The development took place in the year 1997.||AC3 was originally known to be Dolby Stereo Digital until the year 1994. Dolby Laboratories in early 1997 changed the name from “Dolby AC-3 surround sound" to "Dolby Surround Digital" which is nothing but the current format of Dolby Digital.|
|Compatibility||AAC is the widely used format for iPhone, iPod, iPad, Nintendo DSi, YouTube, DivX Plus Web Player and PS3, which are all commonly used devices. It is also compatible with Nokia, Android, Blackberry and webOS operating devices, and also the major brands of audio systems in the cars.||AC3, widely known as Dolby Digital is used in DVDs, Blue-Ray Disks, game consoles and HDTV broadcast standard format.|
AAC compresses files to a smaller size so that the files occupy less space and maintain sound quality at the same time. AAC produces the frequency between 8 to 96 KHz, while AC3 gives out a bit rate of 384 KBPS. If you want to play audios on amplifier system, you should use files in AC3 track for the better effect.
Talking in terms of quality, AAC is more advanced when it comes to the advanced lossy format. It produces better quality audio as compared to AC3, even with the same bitrate, and a better quality with low bitrates. In situations when you want to have better compatibility on older Dolby Digital devices, you should go for the AC3 format.
