From: A Multimedia Application: Spatial Perceptual Entropy of Multichannel Audio Signals

Sampling Rate (kHz) Band Width (kHz) PE (bits/sample) Bitrate (kbps) Near Transparent Coding Bitrate (kbps)
8 0.2–3.2 0.5–2.1 4–16.8 12.2 (AMR [14])
16 0–7 0.5–2.1 8–33.2 23.85 (AMR-WB [15])
32 0–15 0.35–2.1 9.6–67.2 64 (AAC [9])
