What is a VoIP codec?
International VOIP virtual numbers, worldwide VOIP originati...The word "codec" comes from COder/DECoder. A codec defines the algorithm used to convert analog signal into digital signal and vice versa. Each algorithm consumes different amount of bandwidth and provides different voice quality level. In the VoIP world the codecs are used to encode the voice for transmission across an IP backbone. Another name for voip codecs is "vocoders".
Related QuestionsQuestion: Which VoIP codec should I use?
VoIP FAQVoIP codecs convert analog voice signals to their digital encoded version. Codecs vary in size, sound quality, bandwidth and computation requirements. The most common VoIP codecs currently available are: G.711 (alaw & ulaw), G.723, G.726, G.729, GSM, and iLBC.
Related QuestionsWhat is a codec, and where can I get it?
Internet Streaming Media FAQA codec is a downloadable software encoder or decoder for a particular media format that is geared towards a specific computer platform. Codecs function much like plugins for browsers, and are used by players or authoring software to work with the specific media type. Most codecs that you will come across are decoders that are geared to presenting media content to players.
Related QuestionsWhat is the relationship between codec and VoIP?
RARIS: FAQIn order to transfer voice (analog signal) over IP (internet), the voice message must first be digitized. Codec basically transfers voice into data in order to travel through the public internet network. Presently codec algorithms are designed to reduce the size of their voice packets to increase speeds of transmissions and reduce bandwidth loads on the network.

What is a 'codec'?
VoipSmart FAQThe word 'codec' is a joining of encoer/decoder. With respect to voice over IP, a codec is an algorithm used to encode and potentially compress the analogue voice signal into digital form to be transmitted over the Internet. At the remote end, that same codec is then used to decode and decompress the digital signal in order to reproduce the original analogue signal. There are a variety of different codecs available that offer varying levels of compression and quality.

Continuum ResourcesCodec is short for coder/decoder. Codecs are used to compress movies before saving to a file and to uncompress them for playback. Compression is necessary because without it movies would require huge file sizes. Even if there were enough disk space for an uncompressed movie, the computer could not retrieve the movie from the hard drive fast enough for smooth playback. Compression becomes even more important for movies streamed across the internet because of limited bandwidth.Related Questions
Ondine Computing - FastEZ CD and DVD MakerCODEC is an acronym for Codern-Decoder and relates to software or hardware that is installed on PCs, enabling them to create and/or view multimedia files. For example, video editing suites such as QuickTime etc. install CODECs onto the PC that enable the User to view these files. As a general rule, if you capture your video file (for example from your DV camera) onto a PC it's best to create a FastEZ VideoCD using the same PC. (Back to top)Related Questions

Using codecsA codec is software that is used to compress or decompress a digital media file, such as a song or video. Content creators use codecs because a compressed file takes up less storage space on your computer and can be transferred across the Internet more quickly and smoothly. When you play a digital media file, Windows Media Player uses a codec to decompress the file. Codecs are used to create and play nearly all music or video files on your computer or on Web sites.Related Questions

RARIS: FAQThe term codec is a contraption of COder and DECoder. The codec is where the analog to digital transformation is performed. In the PSTN, the Pulse Code Modulation (PCM) scheme is used to generate a 64kbps stream. More “economical” coding schemes have been designed to reduce this stream to 32, 16, and even 8 kbps. The main ITU codec standards are G.711, G.722, G.726, G.728, G.729, G.723.Related Questions
