custom-convert.conf: flac/brutefir 24bit PCM out won't work

[soundcheck]

Hi guys.

I am piping a 16bit flac into brutefir.

My actual goal was to feed a 16 bit flac into brutefir outputting a 24bit PCM stream right to the Touch.

I havn't managed to make it work so far.

Case1:
This is gonna work with brutefir set to 24 bit:

flc flc * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs --force-raw-format --endian=little --sign=signed $START$ $END$ -- $FILE$ | [brutefir] -nodefault /etc/squeezeboxserver/filter/brutefir-filter.conf 2>/tmp/brut.log | [flac] --stdout --silent -0 --force-raw-format --endian=little --sign=signed --channels=2 --bps=24 --sample-rate=44100 -


The needs another flac encoding to make it work on 24bit. The output of brutefir is set to 24_LE.



Case2:
This is gonna work with brutefir set to 16 bit:

flc pcm * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs --force-raw-format --endian=little --sign=signed $START$ $END$ -- $FILE$ | [brutefir] -nodefault /etc/squeezeboxserver/filter/brutefir-filter.conf 2>/tmp/brut.log


No need to do a flac encoding.

Case 3:

brutefir set to 24bit LE.


flc pcm * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs --force-raw-format --endian=little --sign=signed $START$ $END$ -- $FILE$ | [brutefir] -nodefault /etc/squeezeboxserver/filter/brutefir-filter.conf 2>/tmp/brut.log



Does anybody has an idea why Case 3 is not working? (Giving me noise)

Obvioulsy it needs a flac encoding to get the 24bit stream down.
A problem with the 24bit formatting!?!?

Bump.


Why potentially does 16bit PCM out of brutefir works and 24bit PCM won't!?!?

Wrong 24bit formatting/padding!??!

-- which can be read by flac and not by the Touch!??


Has anybody tried anything in that area?

It could be because SBS expects a 16 PCM stream. You have not told SBS that the stream is 24 bits as there is no header on a PCM stream. Perhaps you should try a WAV output which has a header which provides stream format.

This is correct.
Why are you trying to convert it to 24-bit when the Touch will do that itself anyway?
