# Extracted Proposals

Based on my analysis of the document, here are the proposals found in the "Proposal" section (Section 5):

---

Proposal 1: The codec shall be able to operate with an 8 kHz sampling rate, supporting an audio bandwidth of 50 – 4000 Hz.

Proposal 2: The codec shall be able to operate with a 16 kHz sampling rate (50 – 8000 Hz audio bandwidth) to offer enhanced quality where channel conditions and device capabilities permit. For example, WB support can be limited to higher bitrates than NB operation.

Proposal 3: The necessity and feasibility of including Super-Wideband (SWB) and Full-band (FB) support remains for further study.
