Using lame for downsampling flac is clearly not ideal. I expect this to
be changed as soon as someone can come up with a working transcoder
pipeline that can do flac->flac with downsampling while retaining all
the other functionality.
I expect that we will use sox for this, but we need a more up-to-date
build of sox, including with FLAC support (not there by default). This
won't happen in time for 7.3. You could probably construct your own
flac->wav pipeline today with the current sox functionality. I have not
tested this but at a guess the following should work (although I can
foresee a number of problems - it might be necessary to tie down all
the output stream characteristics => 44100/16/2):
Code:
--------------------
flc wav * *
# FT:{START=--skip=%t}U:{END=--until=%v}D:{RESAMPLE=-r %d}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] $RESAMPLE$ -t wav - -t wav -
--------------------
You would probably need to disable the flc-flc-transcode line in the
normal convert.conf file.
If you have a flac-capable sox version around then you could try:
Code:
--------------------
flc flc transcode *
# FT:{START=--skip=%t}U:{END=--until=%v}D:{RESAMPLE=-r %d}
[flac] -dcs $START$ $END$ -- $FILE$ | [flac-capable-sox] $RESAMPLE$ -t
wav - -t flc -
