Narrowband Audio: Narrowband comes in many variations, but the most traditional version of this style of codec is the G.711. G.711 actually refers to two different codecs: G.711 mu-law is used in North America while G.711 a-law is used in Europe. G.711 processes each individual call at 64 kb/s, the same speed as a T0 channel (B Channel on a T1 circuit). It is also the standard codec …

The Opus codec scales from 6 kbit/s narrowband mono speech to 510 kbit/s fullband stereo music. Supports both constant bitrate (CBR) and variable bitrate (VBR). Provides audio bandwidth such as Narrow Band (8 kHz), Middle Band (12 kHz), Wideband (16 kHz), Super Wideband (24 kHz), and Full Band (48 kHz). SMV

Narrowband: G.711, G.726: Offers narrow-band voice with low processing requirements, and with typical bit-rates of 32-64 kbps. Other narrow-band codecs with compression, such as G.729AB and G.723.1, offer bit-rates as low as 5.3 kbps, but require higher DSP processing horsepower. Wideband:

Narrowband codecs – These are codecs that typically digitize sound frequencies between 300 and 3400 Hz, which is the approximate frequency range of the human voice. This limitation of frequencies causes voice to acquire its characteristic “telephone-like” tone.

Other narrowband codecs, such as the AMR-NB codec used for GSM mobile networks, achieve this general frequency output at a lower bandwidth of up to 12.2 kbps, resulting in more complexity in the compression algorithm. HD Voice is enabled through the use of wideband audio codecs, which are sampled at a higher rate of 16 kHz to provide an

iLBC is short for Internet Low Bitrate Codec is an open source narrowband audio codec. If you in a environment where a lot of packet loss and the voice quality is bad, iLBC is a good choice for you. It will provide a good quality when lost frames and delayed happens. The bitrate is 15.2 kbit/s for 20 ms frames, 13.33 kbit/s for 30 ms frames.
Opus Codec - Opus Interactive Audio Codec
It can scale from low bitrate narrowband speech to very high quality stereo music. Supported features are: Bitrates from 6 kb/s to 510 kb/s; Sampling rates from 8 kHz (narrowband) to 48 kHz (fullband) Frame sizes from 2.5 ms to 60 ms; Support for both constant bitrate (CBR) and variable bitrate (VBR) Audio bandwidth from narrowband to fullband
