403224 16 kbit/s Adaptive Differential Pulse Code Modulation (ADPCM) Corrigendum 1: Correction to Annex A: Extensions of Recommendation G.726 for use with uniform-quantized input and output Study Group 16
ITU-T Rec. G.726 contains the specification for the adaptive differential PCM voice-coding algorithm at 16, 24, 32, and 40 kbit/s. Its Annex A contains the specification for linear PCM input and output. This corrigendum to ITU-T Rec. G.726 fixes an omission in Decoder Block LIMO of its Annex A, which limits the output linear two's complement sample to a 14-bit value. The pseudo-code, as originally published, misses the case for reconstructed samples SR equal to 57 344.
