Hi, so I managed to read through the whole thread. Enlightening on
parts, but as I just thought I understand it now turns out I still do
not...
So to keep it simple: I would like to start to upsample all my flacs. I
kept most settings default, even the enable stdin, target sample rate at
closest synchronous supported and I checked all output sample rates up
until 192000 (my spdif limit).
28782
So indeed I see the sox cmd piped to the flac in the resulting command:
Code:
--------------------
flc pcm * [mac address here]
# I noArgs, D RESAMPLE=-r %d, R noArgs, F noArgs
[flac] -dcs --totally-silent $START$ $END$ -- $FILE$ | [sox] -q -t wav - -t
wav -b 24 --buffer 8192 - gain -h rate -v -I -b 90.7 -f 192000
--------------------
and in the pcp_squeezelite.log I can see all flacs upsampled to 192000.
Whether I throw a 44.1kHz, 48, 88.2 or 192 at it.
So now I disable the stdin, resulting command:
Code:
--------------------
flc pcm * [mac address here]
# F noArgs, R noArgs, D RESAMPLE=-r %d
[C-3PO] -c $CLIENTID$ -p "/srv/squeezebox/prefs/plugin/C3PO.prefs" -l
"/srv/squeezebox/logs" -x "/usr/sbin" -i flc -o wav $START$ $END$ $RESAMPLE$
$FILE$
--------------------
I would now expect that it would resample to 176400 (although reading in
the thread I even got the impression since I also checked 88200 this is
closest, so it might become this). In effect though: nothing happens.
So I uncheck all target sample rates except 176400 and 192000 (3CPO.log
at lms mentions them as true/1, $maxsamplerate 192000). I would expect
upsampling to 176400 but in effect again: nothing happens.
Only when I check only 176400 or 192000 (resulting command mentions the
explicit one target sample rate) I get sound again...
So is my expectation that the source file is inspected, a multiple that
matches the highest target sample rate allowed is chosen (ie 176400 for
44.1/88.2, 192000 for 48/96) and used as as target sample rate wrong?
And if not: where am I going wrong in my settings?
