Conversion of Frame Energy to "dBov" - Lingadevaru - Dec 17 3:38:00 2004
|
Hi All, Any one worked on G711-Appendix2...? please help. My Qs is how to convert the frame energy into "dBov"? In G711 appendix2: The Comfort noise payload definition says, The first byte of the payload must contain the noise level.The noise level is expressed in – dBov, with values from 0 to 127 representing 0 to –127 dBov. Also the specification describes that the running average of the frame energy(LE) is computed for every frame. Where LE is the base-2 logarithm of the frame energy. Could you please explain the procedure how to convert this frame Energy to "dBov". thanks -Lingadevaru |
