Tips: AIFF or AAC Format

What is AIFF Format:

AIFF stands for Audio Interchange File Format. It is a standard format used for storing sound data for personal computers and other electronic audio devices. Apple Inc. based on the Electronic Arts’ Interchange File Format (IFF) developed the file format. It is mostly used in Mac computer systems.

What is AAC Format:

AAC or Advanced Audio Coding is an audio coding standard for lossy digital compression designed to be a successor of MP3. It is the default standard audio format for YouTube, iPod, iPhone, iTunes, Playstation 3 and much more.

Differences between AIFF and AAC:

AAC and AIFF coding algorithms are largely used for Apple products although AAC was not developed by Apple. The codecs dictate how the audio is recorded and digitized in digital format. The main difference between AAC and AIFF is the way, which the encoding is done, AIFF is a lossless format meaning that all audio information is retained in the file and nothing is lost. Irrespective of how many times you encode the file between lossless formats, the quality of the sound will be maintained. In contrast, AAC uses a lossy compression, which discards the least valuable data. Converting between lossy or a lossy and lossless file will result in a degraded quality.

The other difference is found on the file size. Since AIFF is lossy and uncompressed, the files encoded in this format are bigger than AAC, which is a lossy file by roughly ten times. Using AIFF means you require a huge hard drive which could be a challenge when media players have a limited drive space.

More so, AIFF is better suited for audio editing while AAC is better suited for personal listening. Lastly, AAC is a popular codec while AIFF is hardly used. Using AIFF drains the battery quicker since the hard drive needs to spin longer to read the whole file.
