3GPP (GSM only) 46-series — CODECs

The technical specifications (TS) are displayed in blue, while the reports (TR) are shown in green. TS that have been discontinued in earlier releases are indicated with a light blue color. TR in the '9' range that have been stopped are highlighted in light green. TS or TR with a yellow background indicate those updated at the latest Q2-2024 Plenary Meetings. The new ones are displayed with a single red dotted overline.
