Hello Michael,
ad 1. No I did not, actually I thought the -b95 was the default setting
for using rate -v, but I might be wrong.
ad 2.
Code:
--------------------
#flc flc * *
#[sox] -v0.965 --buffer 32768 -t flac -r44100 -2 -c2 $FILE$ -t flac -C0 -3
-c2 -r96000 -D - rate -v
flc flc * *
[sox] -v0.965 --buffer 32768 -t flac -r44100 -2 -c2 $FILE$ -t flac -C0 -3
-c2 -r96000 - polyphase -cutoff 1.0
--------------------
Using the polyphase option (sox 14.2) at the moment.
Using -b 24 seems to be unnessecary. You are right sox should not
dither, but it does! You can check this in two ways, either exaggerate
the volume factor (-v5 for example) and you will get dither clipping
errors, proving dither is being applied! Or use -V5 and look at the
debugging output.
Ronald.
