Looking for help playing hi-res audio on your iPhone or iPad? Check out our guide. However, Apple users don't have a choice between the two because iTunes and iOS both provide native support for ALAC and no support for FLAC. While ALAC is good, it's slightly less efficient than FLAC regarding compression. ALAC is sometimes referred to as Apple Lossless. It was developed and launched in 2004 as a proprietary format but eventually became open-source and royalty-free in 2011. That's why many see FLAC as the best audio format.ĪLAC stands for Apple Lossless Audio Codec. With it, you get the full quality of raw uncompressed audio at half the file size. ![]() What's even nicer is that FLAC is an open-source and royalty-free audio file format, so it doesn't impose any intellectual property constraints.įLAC is supported by most major programs and devices and is the main alternative to MP3 for music. What's nice is that FLAC can compress an original source file by up to 60 percent without losing a single bit of data. Maybe it is a bit on the nose, but it has quickly become one of the most popular lossless formats available since its introduction in 2001. Audio File Format: FLACįLAC stands for Free Lossless Audio Codec. The downside is that lossless compressed audio files are bigger than lossy compressed audio files-up to 2x to 5x larger for the same source file. Opposite lossy compression is lossless compression, a method that reduces an audio file's size without ANY data loss between the source and the compressed audio files. It also doesn't offer any real benefits over AAC or OGG, so when MP3 isn't good enough, it's simply more practical to go with one of those two instead of WMA. So yes, in terms of objective compression quality, WMA is actually the better audio file type than MP3.īut since WMA is proprietary, not many devices and platforms support it. Not unlike AAC and OGG, WMA was meant to address some flaws in the MP3 compression method-and it turns out that WMA's approach to compression is pretty similar to those of AAC and OGG. It's a proprietary format created by Microsoft. It was first released in 1999 and has undergone several evolutions since then, all while keeping the same WMA name and extension. For now, it's mostly used by hardcore proponents of open-source software. MP3 and AAC have such strong footholds that OGG has had a hard time breaking into the spotlight-not many devices support it natively-but it's getting better with time. Vorbis was first released in 2000 and grew in popularity for two reasons: It adheres to the principles of open-source software and performs significantly better than most other lossy compression formats (meaning it produces a smaller file size for equivalent audio quality). Instead, OGG is a multimedia container that can hold all kinds of compression formats but is most commonly used to hold Vorbis files-which is why these audio file types are called Ogg Vorbis files. Actually, it's not even a compression format. It's the standard audio compression method used by YouTube, Android, iOS, iTunes, later Nintendo portables, and later PlayStations. The compression algorithm used by AAC is much more advanced and technical than the MP3 music file type, so when you compare the same recording in MP3 and AAC formats at the same bitrate, the AAC one will generally have better sound quality.Įven though MP3 is more of a household format, AAC is still widely used today. It was developed in 1997 as the successor to MP3 while it caught on as a popular digital audio format, it never overtook MP3 as the most popular. ![]() Similar to how Microsoft and IBM developed WAV for Windows, AIFF is an audio file format developed by Apple for Mac systems back in 1988.ĪAC stands for Advanced Audio Coding. Audio File Format: AIFFĪIFF stands for Audio Interchange File Format. However, Mac systems can usually open WAV files without any issues. The WAV file is just a wrapper for the PCM encoding, making it more suitable for Windows systems. Most WAV files contain uncompressed audio in PCM format. This means a WAV file could potentially contain compressed audio, but it's rarely used for that. WAV is a Windows container for different music formats. Many assume that all WAV files are uncompressed audio files, but that's not true. It's a standard developed by Microsoft and IBM in 1991. WAV stands for Waveform Audio File Format (also called Audio for Windows at some point but not anymore). LPCM is the most common form of PCM, which is why the two terms are almost interchangeable at this point. There is a subtype of PCM called Linear Pulse-Code Modulation, where samples are taken at linear intervals. PCM is the most common audio format used in CDs and DVDs. ![]()
