AIFF vs WAV, which audio format is better? What are the differences and similarities between AIFF them? And how to convert between these two formats? This post will detail all information about AIFF and WAV, and introduce some excellent audio converters, such as MiniTool Video Converter.

What Is AIFF?

AIFF, short for Audio Interchange File Format, is one of the most-used audio file formats in the Apple Macintosh Operating System. It was developed in 1988 by Apple based on the IFF format and is a lossless format and audio data is stored in an uncompressed form.

An AIFF file contains the raw audio data, two uncompressed channel information (stereo and mono), bit depth, sample rate, and application-specific data areas. In fact, AIFF is similar to WAV for the Apple Macintosh platform.

Uncompressed in nature, there is no loss of data and quality in the AIFF format, but it takes up a lot of storage space. One minute of an AIFF file takes up approximately 10MB. Therefore, Apple came up with another format called the AIFF-C that is similar to an original AIFF file but with an added feature of audio compression, which helps in reducing the file size.

How to open an AIFF file?

In general, you can open AIFF files in Windows Media Player or iTunes, depending on the operating system. Other programs that open AIFF include VLC media player, Audacity, and Elmedia Player.

What Is WAV?

WAV, short for Waveform Audio File Format, is an audio file format standard, developed by Microsoft and IBM. It is used to store uncompressed audio data with pulse-code modulation, but it can be used to store sound processed with other audio codecs.

The WAV format uses containers to store audio data, track numbers, sample rate, and bit rate, and it is one of the standard formats for audio CDs. The WAV files are uncompressed lossless audio, so it will take up quite a bit of space, coming in around 10 MB per minute with a maximum file size of 4GB.

How to open a WAV File?

The default player for opening WAV files is Windows Media Player. Alternatively, programs such as iTunes, VLC media player, and QuickTime player can also be used to open and play WAV files.
