To convert an audio, follow these simple steps:

  1. Download and launch Movavi Video Converter.
  2. Download and launch Movavi Video Converter.
  3. Add your files to the program.
  4. Choose the output format.
  5. Convert the audio.

Determining the AIFF vs. WAV contest may not be easy because both audio formats output the same quality of sound. Even the most experienced DJ may not tell if there is any noticeable difference between the two audio file formats. But the main difference between the two is that AIFF contains metadata, while WAV doesn't.

DescriptionFiles in the WAV format can contain compressed or uncompressed audio, but usually, they come without compression, so WAV files can be quite large. Uncompressed WAVs are useful for professionals who require the best sound playback quality.The AIFF file type is widely used for storing audio on Mac systems. If you don’t know how to open AIFF files for playback, check out the list of programs below.

Technical detailsThe specification of the WAV file type is based on the RIFF specification. Both formats are containers for audio and store data in tagged “chunks.” Every “chunk” (or block) holds information about a part of a file, and, when creating a WAV, you can even leave some blocks empty to ease future sound editing. As for audio encoding, you can compress a .wav file with the MP3 or AAC codec, but WAV is mostly used for storing uncompressed audio.The AIFF format contains uncompressed audio encoded with pulse-code modulation. AIFF files are made up of chunks that define sound characteristics and other related data. The AIFF specification requires Common Chunk and Sound Data Chunk; other chunks are optional.

If you need to convert your AIFF or WAV files, our special pick for you is Movavi Video Converter. It can convert your video and audio files to over 180 different formats in a couple of clicks and edit the result with built-in options. The interface is easy-to-use, so even a beginner won’t have any problems using it.

AIFF vs. WAV: The main differences

AIFF and WAV play on almost all kinds of computers and devices, though AIFF works mostly for Macs, while WAV is for Windows. The two audio formats employ the same type of encoding that results in large file sizes, but have a better quality sound compared to MP3 and M4V. In the contest pitting AIFF versus WAV, it would be difficult to determine the winner without a detailed analysis of each.

What is a WAV file?

So, what is a WAV file? Short for Waveform Audio File Format, WAV is one of the oldest and simplest high-resolution audio formats developed by IBM and Microsoft in 1991. This audio format works by converting audio signals into binary data, which is then stored as a bitstream format on PC. It stores data in chunks, just like the AIFF format used on Mac computers.

WAV forms the Windows main audio format for raw and uncompressed audio files that use the usual bitstream encoding known as the Linear Pulse Code Modulation (LPCM). The LPCM is the standard coding format for audio CDs that store 2-channel LPCM audio with a sampling of 44,100Hz with 16 bits for each sample.

If you are a professional user and want to do some DJing, WAV would be your best bet. This is because you can easily edit or manipulate WAV files using some software. Although this audio format is by nature uncompressed, allowing for higher quality output, you can compress it on Windows using the Audio Compression Manager (ACM) codec.

You can access the ACM codec via various programs that use them. A good example of such programs is the Sound Recorder found in some versions of Windows OS. But from Windows 2000, the WAV format can specify multiple audio channel data as well as the exact speaker positions to eliminate ambiguity in its output.

Pros

  • Lossless uncompressed format: possible to reproduce a recording without loss in quality.
  • Simple: WAV files are easy to process and edit, even for DJing.
  • High dynamic range: with a high dynamic range of up to 192 kHz, this audio format is best for broadcast companies.
  • Smoother loops: regular frequency makes this audio format produce smooth sound regardless of the file size and beatport.
  • Can work as an interchange medium between platforms: whichever platform you are operating on, WAV can help in transitioning smoothly between different audio formats.

Cons

  • Large file sizes: since WAV is mostly uncompressed, it takes up large spaces on the storage medium. A minute of this audio length may take up to 10 MB of space.
  • Compatibility issues with some playback devices and online use: because of its large size, WAV may have compatibility issues with lighter platforms.
  • Limited support and portability: not many devices support WAV playback, hence, confining to PCs.
  • Can get corrupted easily: this audio format is easy to process, edit, and manipulate, hence, a user can easily corrupt it.
  • Not suitable for online sharing: this file system occupies large chunks of space, making it difficult to share online. You may need to compress it to a smaller file size through conversion to other lighter audio formats, such as MP3, before you can share it via the web.

What is an AIFF file?

So, what is an AIFF file? It stands for Audio Interface File Format, an audio file format developed by Apple in 1988. It is based on the IFF (Interchange File Format). You are more familiar with the MP3 format, but when it comes to the AIFF, you are looking at an uncompressed audio file that retains a higher quality compared to MP3.

But the uncompressed audio files mean that it will occupy more space on your storage media, up to 10 MB per minute of audio recording. It could be a small price to pay if you are looking for high-quality audio output.

AIFF works mostly on Macs and iOS devices, it can also play on Windows with certain media players, such as VLC. Windows appends .aif to such files before reading them, while Macs attach .aiff to them. This means that Windows users will see .aif while those on Mac will see the extension .aiff.

However, it is still possible to compress this audio file format. There is a variant that can utilize compression to achieve less disk space and is called AIFF-C, or simply AIFFC, which stands for Compressed Audio Interchange file Format. As expected, compressed versions of AIFF will have the extension .aifc.

You can open and play AIFF media on Apple iTunes, VLC, Media Player Classic, Windows Media Player, and most other multi-format media players. If you are a Mac user, use those Apple programs to play these audio files, including Roxio Toast. iPhones and iPads should play these audio formats natively without a special app, but if you want to play them on Android phones, you will have to convert to compatible files.

Pros

  • High quality: AIFF is a lossless format that provides better quality audio compared to other audio file formats.
  • High dynamic range: best for audio recording and broadcast since it experiences no decline in quality during recording and playback.
  • Simple: this format is easy to process and edit, and even create beatports, hence, quite suitable for the DJ.
  • Compatibility: AIFF can play on almost all media devices, some natively, while others need an app.

Cons

  • Difficult adding tags: due to its very nature, this file format isn't flexible enough for adding tags even though it has room for metadata.
  • Difficult to share online: it takes up much space because it is uncompressed. As such, it is difficult to share online.
  • Large files: AIFF occurs in uncompressed chunks of files, occupying lots of space. A minute of this audio file length occupies about 10 MB.

Frequently asked questions

Is AIFF better than AAC?

AIFF is lossless, preserving the CD quality of the audio file, but when it comes to iTunes, AAC is preferred because of its compressed state, thus occupying less space and easy to download. But AIFF produces better playback qualities compared to AAC.

What does a WAV file contain?

A WAV file contains uncompressed audio in the Linear Pulse-Code Modulation (LPCM) which preserves all the samples of an audio file at 4.4 kHz with 16 bits per sample.

Is AIFF lossless?

AIFF is a lossless audio format, meaning you get no quality loss. However, it also means such files occupy more space and are less convenient to download.

Can you convert AIFF to WAV?

To convert AIFF to WAV, you can use Movavi Video Converter – user-friendly and powerful software for audio and video files conversion. It works on Windows and Mac, so you won’t have any problems running it on your computer.

Can an iPhone play AIFF?

iPhones should have native support for AIFF files. However, if you can’t play them, you can try using audio player apps like iTunes or QuickTime.
