H], of the lower and higher sub-band ADPCM
decoders from 8 kHz to 16 kHz and which then produce an output, [x.
Moreover, we compare performance of the proposed schemes with the wideband rate distortion bound, which represents the lower bound of performance of several standardized ADPCM
speech codecs for wideband speech, including the G.
1(a)) the additional subsystem for the adaptive prediction is shown (buffer and predictor coefficients estimator which are connected with dotted lines), forming an ADPCM
The system-on-chip ICs transmit voice data via an onboard a-law/[mu]-law audio CODEC with ADPCM
support combined with an [I.
The S1V30120 also supports decoding of ADPCM
data, which allows mixtures of pre-recorded speech and synthetic speech to be combined as required.
Other supported input formats include ADPCM
, CCUIT A-LAW, AIFC, DSP, GSM, CCUIT G721, CCUIT G723, CCUIT G726, MP2 (MPEG 1 Layer 2), MPC (MPEG Plus/MusePack), CCIUT u-Law, VOX, PCM, and RAW.
There is only a limited space to work with, but you can still add a lot of character with ADPCM
