Hi

I am trying to evaluate the quality of the CELT codec by using the 0.8.0
testcelt tool to encode and decode the input.
I want to test different bitrates and selected the below parameters for 64,
96, 128, 196, 256kB:

./celt-0.8.0/libcelt/testcelt.exe 44100 2 256 46 $1.sw $1-64kb.sw
./celt-0.8.0/libcelt/testcelt.exe 44100 2 192 46 $1.sw $1-96kb.sw
./celt-0.8.0/libcelt/testcelt.exe 44100 2 128 46 $1.sw $1-128kb.sw
./celt-0.8.0/libcelt/testcelt.exe 44100 2  96 46 $1.sw $1-196kb.sw
./celt-0.8.0/libcelt/testcelt.exe 44100 2  64 46 $1.sw $1-256kb.sw

can someone comment on the chosen parameters? I am not sure if these are
right settings for frame size and bytes per packet. Is there a better
choice?

Thank you very much in advance

Jochen
