Acelp.net Audio Codec
is a speech codec for Windows Media Player
, developed by VoiceAge - the World's Premier Supplier of Speech and Audio Codecs.
ACELP.net, like prestigious standards such as EFR GSM, IS-136, TETRA, G.723.1, G.729 and G.729 Annex A, is based on ACELP technology. This state-of-the-art technology has now been adapted to meet the needs of IP networks and the PC platform by using an improved, net-adapted packetization method that outperforms conventional approaches. In particular, it minimizes the impact of errors while significantly improving error correction possibilities in case of data-packet losses. Through frame concatenation and interlacing, the communication channel is made more robust.
The ACELP.net family includes a dual-rate codec (8.5/6.5 kbps), a fixed-rate codec (5.0 kbps) and a wideband codec (16 kbps). The dual-rate version of ACELP.net has the ability to switch bit rates on the fly to effectively handle network inconsistencies. ACELP.net provides toll-quality compression at 8.5 kbps and near-toll quality at lower rates.
The ACELP.net family has already gained broad recognition, with ACELP.net being the preferred low bit rate speech codec in RealAudio® and being included in both Microsoft MediaPlayer and Audible ready equipment. This technology can be rapidly harnessed for applications such as broadcast over Internet (multicasting), multimedia email and multimedia conferencing.

Thank God I found your site..I was the Microsoft codec site and couldn't make any sense of it...your page very clear..codec numbers were very straigh forward...keep up the good work.
Microsoft clearly recommends using the ACELP codec by VoiceAge. This is the same codec RealNetworks uses to encode speech. "Indeed, when encoded at just 16 Kbps (one-fourth the size), the ACELP voice codec nearly matches MP3 quality at 64 Kbps!"
