Part 5. Bonus Tip – Common Audio Formats

Audio files come in a variety of sizes and sizes. However, they are divided into three categories. After understanding the definitions of these three categories, it is easy to choose the format that suits you best.

#Uncompressed Audio Formats

Uncompressed audio consists of real sound waves that have been captured and converted to digital format without further processing.

WAV

WAV – Waveform Audio format, introduced in 1991 by Microsoft and IBM, is one of the most widely used uncompressed formats for audio files. The audio container uses uncompressed technology and is primarily used to store recordings in CDs.

PCM

PCM – Pulse-Code Modulation, is a digital representation of raw analog audio signals. PCM is the most commonly used audio format for CDs and DVDs. There is no compression involved.

AIFF

AIFF – Audio Exchange File Format, is a format that Apple developed for the Mac system in 1988. It can contain multiple audio formats. Most AIFF files contain uncompressed audio in PCM format.

#Audio Formats with Lossy Compression

Lossy compression means sacrificing sound quality and audio fidelity for smaller file sizes. When it’s done well, you won’t be able to hear the difference.

MP3

MP3 – MPEG-1 Audio Layer 3, was released in 1993. It is the world’s most popular audio format for music files. Almost all digital devices with audio playback in the world can read and play MP3 files.

AAC

AAC – Advanced Audio Coding, was released in 1997. AAC uses a much more advanced compression algorithm than MP3. It is a standard audio compression method used by YouTube, Android, iOS devices, iTunes, and later Nintendo’s laptops, and later PlayStation consoles.

#Audio Formats with Lossless Compression

Lossless compression is a method that reduces an audio file’s size without any loss of data. The downside is that lossless compressed audio files are bigger than lossy compressed audio files

FLAC

FLAC – Free Lossless Audio Codec, was launched in 2001. It can compress up to 60% of the original source file without losing any data. FLAC is an open source and royalty-free audio file format, so it does not have any intellectual property restrictions.
