transcoding MP3 to 96k FLAC

Hello All,

I have a Yggdrasil DAC that to my ears is the best sounding DAC I have owned. The only problem I have with it is that when it changes to a different sampling rate it CLICKS and sometimes the first moment of the music is cut off. I've tried to live with it but the clickity clack of my playlists are getting under my skin.

I would like to up-sample all music coming from my Transporter to 96k to avoid this annoyance. I found a configuration that works very nicely for FLAC, but MP3 and AAC (.m4a) elude me. Has anyone done this before? Here is what my custom-convert.conf looks like.

flc flc * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -q -t wav - -t flac -e signed -C 0 -b 24 - rate -v -b 98 -L -a 96000

mp3 flc * *
[lame] --mp3input --decode -t --silent $FILE$ - | [sox] -q -t wav - -t flac -e signed -C 0 -b 24 - rate -v -b 98 -L -a 96000

aac flc * *
# IF
[faad] -q -w -f 1 $FILE$ | [sox] -q -t wav - -t flac -e signed -C 0 -b 24 - rate -v -b 98 -L -a 96000


Any advice is appreciated. Thanks for the help!

Regards,
Ernie
