m4v	video/mp4	M4V is a standard file format for videos for iPod and PlayStation Portable devices developed by Apple. It is based on the MPEG-4 Part 2 compression.
mp4	video/mp4	MPEG-4 is a multimedia container format standard that is most commonly used to store digital audio and digital video streams, especially those defined by MPEG. It can also be used to store other data such as subtitles and still images. MPEG-4 files with audio and video generally use the standard mp4 extension.

mpg4	video/mp4	Another file name extension for MPEG-4 files.
ram	video/3gpp	RealAudio metadata (RAM) is typically a small text file that contains a link to the audio stream.
rm	application/vnd.rn-realmedia	RealMedia is a multimedia container format created by RealNetworks that is typically used in conjunction with RealVideo and RealAudio for streaming content over the Internet.
rmvb	application/vnd.rn-realmedia-vbr	RealMedia variable bitrate (RMVB) is a container streaming content over the Internet with variable bit rate.
rtp	application/x-nokia-teh-rtp
rv	video/vnd.rn-realvideo	RealVideo is a proprietary video format developed by RealNetworks that is usually paired with RealAudio and packaged in a RealMedia (rm) container.

The following table describes the supported audio files.

3gpp	audio/3gpp	Another file name extension for 3GPP files.
aac	audio/aac	Advanced audio coding (AAC) is a standardized, compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at many bit rates.
amr	audio/amr	A file format for storing spoken audio using the adaptive multi-rate (AMR) codec. AMR is a patented audio data compression scheme optimized for speech coding.
au	audio/au	A simple audio file format.
awb	audio/amr-wb	Adaptive multi-rate – wide band (AMR-WB) is a patented speech coding standard developed after the AMR that provides excellent speech quality due to wider speech bandwidth.
m4a	audio/mp4	Audio-only MPEG-4 files generally have an m4a extension. This is especially true of non-protected content.
mid	audio/midi	Musical instrument digital interface (MIDI) is an industry-standard protocol that enables electronic musical instruments, such as keyboard controllers, computers, and other electronic equipment, to communicate, control, and synchronize with each other.
midi	audio/midi	Another file name extension for MIDI files.
mp3	audio/mpeg	MPEG-1 audio layer 3, more commonly referred to as MP3, is a patented digital audio encoding format using a form of data compression. It is a common audio format for consumer audio storage and widely used for digital audio compression for the transfer and playback of music on digital audio players.
mp4	audio/mp4	MPEG-4 files with audio and video generally use the standard mp4 extension.
mxmf	audio/vnd.nokia.mobile-xmf	The extensible music format (XMF) is a tree-based digital container format used to bundle music-oriented content, such as a MIDI file and optionally the sounds it uses, liner notes or other content grouped by language-codes.
nrt	-	Nokia Ringing Tone.
ra	audio/vnd.rn-realaudio	RealAudio is a proprietary audio format developed by RealNetworks. It uses a variety of audio codecs, ranging from low-bitrate formats that can be used over dialup modems, to high-fidelity formats for music.
rng	application/vnd.nokia.ringing-tone	Nokia Ringing Tone.
spmid	audio/sp-midi	Scalable polyphony MIDI (SP-MIDI) is a MIDI variant for mobile applications where different players may have different numbers of musical voices. SP-MIDI is a component of 3GPP.
wav	audio/wav	Waveform audio format is a Microsoft and IBM audio file format standard for storing an audio bit stream on computers.
wma	audio/x-ms-wma	Windows Media Audio (WMA) is an audio data compression technology developed by Microsoft as a part of the Windows Media framework.
