leftPeak & rightPeak values don't seem to correspond to volume

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Added function to measure volume: 
(100 * ((channel.leftPeak + channel.rightPeak) / 2.0))

2. Value was always very low (or 0), so I decided to measure each value in 
function buffer.

Recorded sample was soft, then loud, then soft. The number seem all over the 
place.

Sample output attached.

here is a fix that gives a more useable value
Replace this code in WavSoundChannel.as (buffer function)
            if (!finished) {
                for (var i:int = 0; i < sampleBufferLength; i++) {
                    if (!finished) {                    
                        // write (transformed) samples to buffer
                        var sampleLeft:Number = samplesLeft[phase] * volumeLeft;
                        sampleBufferLeft[i] += sampleLeft;
                        leftPeakRecord = Math.max(Math.abs(sampleLeft), leftPeakRecord);
                        var channelValue:Number = ((needRightChannel && hasRightChannel) ? samplesRight[phase] : samplesLeft[phase]);
                        var sampleRight:Number = channelValue * volumeRight;
                        sampleBufferRight[i] += sampleRight;
                        rightPeakRecord = Math.max(Math.abs(sampleRight), rightPeakRecord);

                        // check playing and looping state
                        if (++phase >= samplesLength) {
                            phase = startPhase;
                            finished = loopsLeft-- == 0;
                        }
                    }
                }

                if (finished) {
                    dispatchEvent(new Event(Event.SOUND_COMPLETE));
                }
            }

            _leftPeak = leftPeakRecord;
            _rightPeak = rightPeakRecord;
