What is an AIFF file?

AIFF stands for Audio Interchange File Format and has existed since the late 80s. Created by Apple Inc. for use primarily on Macintosh systems, AIFF files are highly regarded for their high-quality audio and lossless compression properties. It makes them popular among professionals in the music industry and audiophiles.

Quick Definition: An important file format popular to effectively store sound data using your personal computers or any other electronic audio devices.

AIFF is one of the essential audio file formats that come up with a standard to store the sample sounds. It offers flexibility and allows users to store monaural and multichannel audio samples at different rates and widths.

Check some crucial aspects of the AIFF sound file:

  • Audio Fidelity

One of the hallmarks of AIFF files is their unrivaled audio fidelity. AIFF files store audio data using Pulse Code Modulation (PCM), which captures all range and depth of sound without any loss in quality. AIFF files are an excellent solution for recording, editing, and playing back high-quality audio without lossy compression.

  • File Size and Compatibility

AIFF files offer excellent audio quality but tend to be larger in file size compared to more conventional audio formats like MP3 or AAC. It has compatibility with various audio software and hardware devices - particularly those within the Apple ecosystem. As a result, they are popular choices among professionals.

  • Use in Professional Audio Production

AIFF files have long been an essential element of professional audio production. It is used by music producers, sound engineers, and musicians to record and edit without compromising audio quality during production. Once recorded in AIFF format, these files can easily be converted to more space-efficient formats for distribution.

AIFF File Structure

At its core, an AIFF file consists of various chunks of data encasing audio information - waveform, metadata, and format details. These chunks are organized in a specific sequence for easy playback and manipulation.

EA IFF 85 has the complete structure to store data in the files. It includes various chunks of data. The two general chunks in its structure include:

  • Common Chunk:

The common chunk is an essential part of the file that contains the parameters describing your sample sound, like sample rate, length, and more.

  • Sound Data Chunk:

This chunk carries the actual audio samples. Various optional chunks are also there with defined markers, instrument parameters, save information regarding application, etc.

AIFF File Sharing

As you know, AIFF was designed by Apple, so it runs on Macs and iOS. Thus, iTunes and Apple Music are the perfect platforms to listen to AIFF sound files. It can also easily work on different apps on Mac, like Final Cut Pro. It shows that it is not restricted only to the software of Apple.

Moreover, many people dedicatedly use Windows or Android devices. AIFF files are acceptable in many media players like Windows Media Player. However, a third-party player will be required while on Mac or iOS; it gets played natively.

Now, let's focus on its sharing!

Undoubtedly, AIFF audio files are large. It is a downside when it comes to sharing these files. For instance, a file of one minute can have a size of up to 10Mb. The big sizes of AIFF file formats make it impractical to share them. Also, if you want to use your video content on social platforms like YouTube or TikTok, this file format is unsuitable as they prefer smaller file sizes.

One solution for you is to use the compressed version of AIFF. It is popularly known as the AIFF-C format. It utilizes less space in the hard drive than a regular AIFF file. You should remember that these files come in different file extensions, which is ".affic."

When you check the quality, there is no difference between the AIFF and AIFF-C file formats. An essential consideration is that old media players might experience difficulty in running them. But, the modern ones can play them appropriately.

Furthermore, the AIFF format cannot support the metadata efficiently, making it tougher to tag files than other file extensions. It shows the challenges when dealing with large volumes. It can become problematic when an enterprise needs fast search capabilities for particular files.

How to Open an AIFF File?

The users can easily open AIFF files and then play the audio file they have with different media players like below:

  • Apple Music
  • Microsoft Windows Media Player
  • Apple QuickTime Player
  • VideoLAN VLC media player

Besides, it is already mentioned that iPhone and iPad devices should play AIFF/AIF files natively without using any application.
