First of all, the AIFF stands for Audio Interface File Format, while the full meaning of AAC is Advanced Audio Coding. The two are coding algorithms that are mostly used by Apple products. These two codecs show how the audio is recorded and digitized in digital format. The way by which encoding is done in both AIFF and AAC makes a significant difference between them.

AIFF is known to be a lossless format, which simply indicates that nothing is lost in the audio information, but they are all kept in the file. The quality of sound remains the same irrespective of the number of times you encode the file.

AAC, on the other hand, makes use of a lossy compression algorithm, which discards information that is considered less important. When you convert a lossy to a lossy or a lossy to a lossless codec, the more you do it, the more it gets worse in quality.

AIFF and AAC are two coding algorithms that are used mostly by apple products, although the latter was not developed by Apple.

AIFF stands for an audio interchange file format. It is a lossless format, which means that all audio information is kept in a safe file, and nothing is lost. AIFF is lossy and uncompressed files encoded in this format is much bigger; when using AIFF it means that you will need a huge hard drive. AIFF can also drain your battery quicker.

AAC stands for advanced audio coding; it uses a compression algorithm that discards the least important data. AAC is very popular, that is why Apple has decided to use it as their default file format for their iPod and music stores. AAC is better suited for personal listening.

AIFF and AAC are two things related to audio. AFF is an abbreviation for the audio interchange file format. Apple created this format, and it is used in many Apple products. AAC is also an abbreviation, which stands for advanced audio coding.

While AAC is also used in Apple products, Apple is not the creator of the coding. Audio messages that are in Apple products are kept in AIFF. Doing so has it saved in a format that is lossless, which means the data is not compressed. AAC is used in music devices and stores. This coding is better for does that do leisure listening.

AIFF stands for the audio interchange file format, and AAC stands for advanced audio coding. The two are coding algorithms that are utilized mostly for Apple products. One of the key variances between the two is that Apple did not create AAC. These codes determine how audio is recorded and put in digital format, and another difference is how encoding is accomplished.

All of the audio messages are kept in the file with AIFF, which is a lossless format. This format means that all audio data is kept in an uncompressed file, and nothing is lost. AAC is an accessible format that Apple uses as a default for iPods and music stores. Therefore, AAC is better suited for personal listening. You rarely see AIFF used in music players. Also, AIFF files are much more significant.
