This vocoder is commonly used in VoIP gateways and is the vocoder in Microsoft’s NetMeeting software. It is called the Multi-rate Coder and has two bit rates, 5.3 and 6.4 Kbits/second. This vocoder algorithm has silence suppression, meaning silence is not transmitted and does not occupy bandwidth, and is patented, the use for which a license must be paid.
is an audio representation used in H.324, providing roughly 3.5KHz frequency response in a 6,300-bit communication channel.
An audio compression standard used for digital telephones on a digital PBX/ ISDN that produces digital audio at either 6.4 or 5.3 Kbps. G.723-compliant devices can communicate with other G.723 devices, but not with G.711 devices.
audio coding standard providing voice quality (300 Hz to 3400 Hz) at 5.3 / 6.3 kbps.
Voice compression algorithm that compresses digital voice to either 5.3 or 6.4kbps.
An ITU-T Recommendation entitled, "Dual Rate Speech Coder for Multimedia Communication Transmitting at 5.3 and 6.4 kbps".
Audio (Voice) Compression Protocol reducing the required bandwidth per call, per direction to 8 kbps using adaptive multi-rate wideband.
G.723 is a ITU-T standard wideband speech codec. This is an extension of Recommendation G.721 adaptive differential pulse code modulation to 24 and 40 kbit/s for digital circuit multiplication equipment application.
