Description

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

boosts higher quality audio reproduction than MP3 and requires

 

 

 

 

 

 

30% less data to do so.

 

 

 

 

AMR-NB, AMR-

 

Adaptive Multi Rate offers a wide range of data rates. The

 

 

 

WB

 

 

philosophy behind AMR is to lower the data rate as the

 

 

 

 

 

 

interference increases to enable better error correction.

 

 

 

 

 

 

 

 

 

 

 

 

GSM FULL RATE

 

Format for speech coding used in most GSM networks. The GSM

 

 

 

 

full rate requires one full rate traffic channel to carry its data. The

 

 

 

 

 

 

 

 

 

 

 

 

compression involves mapping input blocks of 160 speech

 

 

 

 

 

 

samples to encoded blocks of 260 bits.

 

 

 

 

MP3

 

 

The MP3 format (.mp3) provides the coding of audio for digital

 

 

 

 

 

storage.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Real Audio

 

Real Audio (.ra, .rm) is a compressed format suitable for streaming

 

 

 

 

over the internet.

 

 

 

 

 

 

 

 

 

 

 

WAV

 

 

Format for storing files (.wav). Linear pcm 8-bit and 16-bit, CCITT

 

 

 

 

 

A-law and U-law.

 

 

 

 

 

 

 

 

 

 

 

WMA

 

 

Windows Media Audio (.wma), referring to components of the more

 

 

 

 

 

general Windows Media Format proprietary standard.

 

 

 

 

 

 

 

 

 

XMF

 

 

Mobile XMF-MIDI: XMF (eXtensible Music Format) is an open

 

 

 

 

 

standard file format for gathering together into a single file all

 

 

 

 

 

 

 

 

 

 

 

 

media assets (and/or links to external media assets) required to

 

 

 

 

 

 

render a MIDI note-based piece (or suite of related pieces) in a

 

 

 

 

 

 

computer-based player (or possibly an instrument) with consistent

 

 

 

 

 

 

audio playback across all players and platforms, and suited for

 

 

 

 

 

 

interactivity, content protection, meta-data, and the Internet – and

 

 

 

 

 

 

keep it simple.
