The 'MP3 & Audio' section consists of the programs which convert audio files between different formats, convert audio files to Flash for web, extract audio from video files, edit audio files (Free Audio Dub), rip and burn CDs. Enclosed in the CD-DVD-BD section are the applications that enable users to burn files and folders to discs, to convert videos to a DVD format and vice versa, to burn CDs, and to copy CDs into digital music files. The 'DVD and Video' section contains several desktop video and DVD converters. Some of the programs can flip, rotate and cut (Free Video Dub) videos. One of the most popular programs from the section is Free Video Dub.

Switch Audio File Conversion Software

FLAC, AAC, Ogg and other lossless formats were becoming more popular in the early 2000's, so Software such as Switch was needed to help users move audio files from one device to another and migrate old legacy audio formats into more efficient modern formats. The ability for a computer user to convert audio files becomes critical when they are unable to edit or use a particular audio file format due to limitations within their software or hardware platforms. Switch gives users the ability to convert WAV, MP3, WMA, M4A, Ogg, AVI, MID and most other audio file formats (40+ formats supported, see charts below).

Music Player Daemon

Can be used as a source for an Icecast stream, in Ogg Vorbis and MP3. Other formats can be converted to Ogg/MP3 on the fly before output to the stream server. Built-in HTTP streaming server, capable of producing Ogg Vorbis and MP3 streams of a chosen quality on-the-fly. Independent of a GUI. Music will continue playing whether a front-end is open or not, and will continue playing even if the X server is killed.

VP9) alongside audio data in an audio coding format (e.g. Opus). The container can also contain synchronization information, subtitles, and metadata such as title. A standardized (or in some cases de facto standard) video file type such as .webm is a profile specified by a restriction on which container format and which video and audio compression formats are allowed. The coded video and audio inside a video file container (i.e. not headers, footers, and metadata) is called the essence.

2000s in the music industry

A-la-carteadvancing state of music distributionchallenges for the record industry
Rise of MP3 players, which are consumer electronics devices that stores, organizes and plays audio files. Some DAPs (digital audio players) are also referred to as portable media players as they have image-viewing and/or video-playing support. The first mass-produced DAP was created in 1997 by SaeHan Information Systems, which domestically sold its “MPMan” player in the middle of 1998. In October 2001, Apple Computer (now known as Apple Inc.) unveiled the first generation iPod, the 5 GB hard drive based DAP with a 1.8" Toshiba drive. With the development of a minimalistic user interface and a smaller form factor, the iPod was initially notable within users of the Macintosh community.


Regardless of the desktop media player, or the amount of storage capacity on a mobile phone, Didiom scanned a computer, and made the media collection available for wireless streaming and downloading to mobile phones. All streams were SSL encrypted for high-value transmissions, such as online banking transactions. Didiom's technology supported audio files in the format of DRM-free and DRM-protected Windows Media Audio (WMA), MP3, WAV, Advanced Audio Coding (AAC), M4A and Ogg Vorbis, as well as iTunes playlists, and playlists in Windows Media Player Playlist (WPL), PLS and M3U formats.

In March 2014, Young announced that Pono would provide "the finest quality, highest-resolution digital music from both major labels and prominent independent labels" using the FLAC audio file format. $6.2M of funding for the project was raised via preorders for the player using the crowdfunding platform Kickstarter. In June 2014, Young assumed the title of CEO of Pono Music. The Pono player and music store was officially launched in January 2015. On July 17, 2016, Pono Music announced that their online music store would be temporarily shut down due to the acquisition of their content partner, Omnifone, by "a large company".

Media Foundation

Enhanced Video RendererEVRMicrosoft Media Foundation framework
The frame rate of the output video is synchronized with the frame rate of the reference stream. If any of the other streams (called substreams) have a different frame rate, EVR discards the extra frames (if the substream has a higher frame rate), or uses the same frame more than once (if it has a lower frame rate). Windows Media Audio and Windows Media Video are the only default supported formats for encoding through Media Foundation in Windows Vista. For decoding, an MP3 file source is available in Windows Vista to read MP3 streams but an MP3 file sink to output MP3 is only available in Windows 7.

Most AAC files with finite length are wrapped in an MPEG-4 container (.mp4, .m4a), which is supported natively in Internet Explorer, Safari, and Chrome, and supported by the OS in Firefox and Opera. Most AAC live streams with infinite length are wrapped in an Audio Data Transport Stream container (.aac, .adts), which is supported by Chrome, Safari, Firefox and Edge. Many browsers also support uncompressed PCM audio in a WAVE container. In 2012, the free and open royalty-free Opus format was released and standardized by IETF. It is supported by Mozilla, Google, Opera and Edge. This table documents the current support for audio coding formats by the element.

Audio converter

For example, an audio transcoder converts from one compressed audio format to another (e.g., MP3 to AAC) by means of two audio codecs: One for decoding (uncompressing) the source and one for encoding (compressing) the destination file or stream.

Comparison of audio player software

Comparison of media playersaudio playeraudio players
The following comparison of audio players compares general and technical information for a number of software media player programs. For the purpose of this comparison, "audio players" are defined as any media player explicitly designed to play audio files, with limited or no support for video playback. Multi-media players designed for video playback, which can also play music, are included under comparison of video player software. This section lists the operating systems on which the player works. There may be multiple versions of a player for different operating systems.


MPG.mpgMPEG-1 Part 2
Layer I audio files typically use the extension .mp1 or sometimes .m1a MPEG-1 Layer II (MP2—often incorrectly called MUSICAM) is a lossy audio format designed to provide high quality at about 192 kbit/s for stereo sound. Decoding MP2 audio is computationally simple, relative to MP3, AAC, etc.

HD-AACScalable Lossless CodingMPEG-4 Scalable To Lossless (SLS)
MPEG-4 SLS, or MPEG-4 Scalable to Lossless as per ISO/IEC 14496-3:2005/Amd 3:2006 (Scalable Lossless Coding), is an extension to the MPEG-4 Part 3 (MPEG-4 Audio) standard to allow lossless audio compression scalable to lossy MPEG-4 General Audio coding methods (e.g., variations of AAC). It was developed jointly by the Institute for Infocomm Research (I 2 R) and Fraunhofer, which commercializes its implementation of a limited subset of the standard under the name of HD-AAC. Standardization of the HD-AAC profile for MPEG-4 Audio is under development (as of September 2009).

Variable bitrate

VBRvariable bit ratevariable
MP3, WMA and AAC audio files can optionally be encoded in VBR, while Opus, Vorbis are always in VBR. Variable bit rate encoding is also commonly used on MPEG-2 video, MPEG-4 Part 2 video (Xvid, DivX, etc.), MPEG-4 Part 10/H.264 video, Theora, Dirac and other video compression formats. Additionally, variable rate encoding is inherent in lossless compression schemes such as FLAC and Apple Lossless. The advantages of VBR are that it produces a better quality-to-space ratio compared to a CBR file of the same data.

Podcasting is a variation on this theme, where – usually audio – material is downloaded and played back on a computer or shifted to a portable media player to be listened to on the move. These techniques using simple equipment allow anybody, with little censorship or licensing control, to broadcast audio-visual material worldwide. Digital media streaming increases the demand for network bandwidth. For example, standard image quality needs 1 Mbit/s link speed for SD 480p, HD 720p quality requires 2.5 Mbit/s, and the top-of-the-line HDX quality needs 4.5 Mbit/s for 1080p. Webcams are a low-cost extension of this phenomenon.

On October 23 of the same year, Apple debuted the iPod portable digital audio player. The product, which was first sold on November 10, 2001, was phenomenally successful with over 100million units sold within six years. In 2003, Apple's iTunes Store was introduced. The service offered online music downloads for $0.99 a song and integration with the iPod. The iTunes Store quickly became the market leader in online music services, with over five billion downloads by June 19, 2008. Two years later, the iTunes Store was the world's largest music retailer.

Compact disc

CDCDsCD single
Monaural audio has no existing standard on a Red Book CD; thus, mono source material is usually presented as two identical channels in a standard Red Book stereo track (i.e., mirrored mono); an MP3 CD, however, can have audio file formats with mono sound. CD-Text is an extension of the Red Book specification for audio CD that allows for storage of additional text information (e.g., album name, song name, artist) on a standards-compliant audio CD. The information is stored either in the lead-in area of the CD, where there is roughly five kilobytes of space available, or in the subcode channels R to W on the disc, which can store about 31 megabytes.

Some proprietary multimedia applications, such as Spotify, use a peer-to-peer network along with streaming servers to stream audio and video to their clients. Peercasting for multicasting streams. Pennsylvania State University, MIT and Simon Fraser University are carrying on a project called LionShare designed for facilitating file sharing among educational institutions globally. Osiris is a program that allows its users to create anonymous and autonomous web portals distributed via P2P network. Bitcoin and alternatives such as Ether, Nxt and Peercoin are peer-to-peer-based digital cryptocurrencies. Dalesa, a peer-to-peer web cache for LANs (based on IP multicasting).

Digital video

PACo could stream unlimited-length video with synchronized sound from a single file (with the ".CAV" file extension) on CD-ROM. Creation required a Mac; playback was possible on Macs, PCs, and Sun SPARCstations. QuickTime, Apple Computer's multimedia framework appeared in June 1991. Audio Video Interleave from Microsoft followed in 1992. Initial consumer-level content creation tools were crude, requiring an analog video source to be digitized to a computer-readable format.
