| Features |
| *Average bit-rate VBR |
| -Add maximum/minimum bit-rate control for VBR |
| *Add "VAD-only" VBR (constant bit-rate or comfort noise) |
| -Get the encoder to use the rate of packet loss (more conservative pitch gains) |
| -No transmission when constant noise/silence |
| |
| Long-term quality improvements |
| -Improve perceptual enhancement (including wideband) |
| -Improve VAD and VBR |
| -Packet-loss concealment |
| |
| Standards |

| -MIME type registration |
| -MS ACM wrapper |
| |
| *required for 1.0 |
