Editing G.726 (section)

==Features==
*Sampling frequency 8&nbsp;kHz
*16&nbsp;kbit/s, 24&nbsp;kbit/s, 32&nbsp;kbit/s, 40&nbsp;kbit/s bit rates available
*Generates a [[bitstream]], therefore frame length is determined by [[packetization time]] (typically 80 samples for 10&nbsp;[[millisecond|ms]] frame size)
*Typical [[algorithmic delay]] is 0.125&nbsp;ms, with no [[look-ahead delay]]
*G.726 is a waveform speech coder which uses Adaptive Differential Pulse Code Modulation ([[ADPCM]])
*[[PSQM]] testing under ideal conditions yields [[mean opinion score]]s of 4.30 for G.726 (32&nbsp;kbit/s), compared to 4.45 for [[G.711]] ([[μ-law]]){{citation needed|date=October 2019}}
*PSQM testing under network stress yields mean opinion scores of 3.79 for G.726 (32&nbsp;kbit/s), compared to 4.13 for G.711 (μ-law)
* 40&nbsp;kbit/s G.726 can carry 12000&nbsp;bit/s and slower modem signals, while 32&nbsp;kbit/s G.726 can carry 2400&nbsp;bit/s and slower modem signals well and 4800&nbsp;bit/s with some more degradation than clear channel codecs.
