Re: FW: REALLY Bad encoding performance of Linux SBC audio codec

Hello, 

the sound quality got better. Still, both encoder and decoder are not as
good as the reference.


For example, not the audio quality measured with ODB(BV) is

Algorithm
ODG(BV)
In0Filename
In1Filename
PEAQBasic
             -1.99
ref.wav
tmp.bluez.wav
PEAQBasic
              -1.5
ref.wav
tmp.bluezref.wav
PEAQBasic
             -0.82
ref.wav
tmp.refbluez.wav
PEAQBasic
             -0.44
ref.wav
tmp.ref.wav


If I use the simple perceptual model of the reference implementation
(option -p), the encoding quality get even better.

Algorithm
ODG(BV)
In0Filename
In1Filename
PEAQBasic
             -1.99
ref.wav
tmp.bluez.wav
PEAQBasic
              -1.5
ref.wav
tmp.bluezref.wav
PEAQBasic
             -0.55
ref.wav
tmp.refbluez.wav
PEAQBasic
             -0.17
ref.wav
tmp.ref.wav

Here the old values before Frans's patch

Algorithm
ODG(BV)
In0Filename
In1Filename
PEAQBasic
              -1.5
ref.wav
tmp.bluezref.sw.wav
PEAQBasic
             -3.89
ref.wav
tmp.bluez.sw.wav
PEAQBasic
             -3.88
ref.wav
tmp.refbluez.sw.wav
PEAQBasic
             -0.44
ref.wav
tmp.ref.sw.wav

Greetings

 Christian
