Audio File Formats
Just like video and photos, audio is available in a variety of
types and formats. The audio file format is a type of file used
to store digital audio on devices like smartphones and PCs. Bit
layout refers to the way that audio data is encoded in a file
as bits. These bit layouts can be compressed using lossless or
lossy encoding, or they can be left uncompressed.
File Description
.au Sun Microsystems created the audio AU format, which was used in
the early days of the web and on their NeXT computers.
.iff A common file type developed by Electronic Arts is an IFF file. It is
used to exchange multiple types of data across apps and systems
and may contain image, text, or audio data. Many applications can
open IFF files like Adobe Audition 2022 on Windows and Apple
QuickTime Player on Mac.
.mid, .rmi The Standard MIDI File (SMF) is a file format that offers a standardised
method for saving, transferring, and opening music sequences in
other systems. The MMA created and upholds the standard, which
often employs a .mid extension. Windows Media Player, VLC, and
Apple’s Logic Pro can all open MIDI files.
Microsoft Windows combines SMFs and Downloadable Sounds
(DLS) files in Resource Interchange File Format (RIFF)-wrapped
RMID files with the .rmi extension.
.mod A music module file saved in the common music module format.
It was derived from the Amiga module format. It includes sound
samples that represent various instruments and note patterns (much
like a MIDI file), which are played back in time with the notes. Video
games frequently employ MOD files for their background music.
.qt A QuickTime movie can just have audio and no visuals. QT sound
files can be played by any application that supports QuickTime.
.snd The file extension SND (SouND) denotes that a file is a digital
sound file. It can be opened on Windows Media Player or Apple’s
QuickTime Player.
.voc The Creative Voice audio format, which uses the .voc file extension,
was created in the 1990s for use with Creative Technology’s Sound
Blaster sound cards. Sadly, there are not many applications that can
play VOC files because the VOC format is not widely supported.
However, VOC files can be opened and played by Faasoft Video
Converter and Faasoft Audio Converter. These tools can be used to
convert data as well.
