Line 67:

** The residual waveform is coded using [[algebraic code excited linear prediction]] (ACELP).

* The complexity of the algorithm is rated at 5, using a relative scale where [[G.711]] is 1 and [[G.729a]] is 15.

* [[PSQM]] testing under ideal conditions yields [[Meanmean Opinionopinion Scorescore]]s of 4.14 for AMR (12.2 kbit/s), compared to 4.45 for [[G.711]] (µ-law){{citation needed|date=October 2019}}

* [[PSQM]] testing under network stress yields [[Meanmean Opinionopinion Scorescore]]s of 3.79 for AMR (12.2 kbit/s), compared to 4.13 for [[G.711]] (µ-law)
