26.4453GPPCodec for Enhanced Voice Services (EVS)Detailed algorithmic descriptionRelease 15TS

The CELP and MDCT decoder output signals are sample rate converted, depending on the selected output sample rate, i.e. 8 kHz, 16 kHz, 32 kHz or 48 kHz. The CELP signal is resampled by the CLDFB, while the MDCT part is resampled by its frequency to time transformation.
