HI
I was experimenting with the lame encoder in order to assess the
effect of perceptual entropy on quality( I am measuring quality using
EAQUAL tool which gives objective Difference grade) The encoding
parameters were as follows:
Mode : Stereo
Sampling Rate: 44100 Hz
Bit rate : 128 kbps
Psychomodel : Off
Noise shaping: On
Block types: All long
Reservoir is not enabled
When I increase the default Perceptual entropy from 700 all the way upto
3000 I see no improvement in quality. I thought that the Bit allocation
module would allocate more bits to each frame if I increase the PE( even
though this may not be the smart thing to do since all frames do not
have same complexity)
Could anybody explain this strange behaviour ..I mean I always
thiught more bits mean better quality
Thanks and regards,
Manjunath
