After noticiting that playing a track for the second time it sounds
better then the first time, I did some research.
The second time a track plays, its read from the linux OS disk cache
instead from disk. This means the track is played from RAM memory
instead of from the hard drive that containt the file (track).
So I was looking for a way to copy a track to RAM memory before it is
being played. I came up with a very simple but effective solution that
works fine.
By modifying my custom-convert.conf from:
Code:
--------------------
flc flc * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox14.4.2] -v0.98 --buffer 32768 -q -t
wav - -t flac -e signed -C0 -b24 - rate -v -M -a -b 90.7 96000 dither -S
--------------------
to:
Code:
--------------------
flc flc * *
# FT:{START=--skip=%t}U:{END=--until=%v}
cp $FILE$ /dev/null; [flac] -dcs $START$ $END$ -- $FILE$ | [sox14.4.2] -v0.98
--buffer 32768 -q -t wav - -t flac -e signed -C0 -b24 - rate -v -M -a -b 90.7
96000 dither -S
--------------------
Search for the difference ;D
It's this:
cp $FILE$ /dev/null;
before the sox upsampling command.
What this does is: copy the file (track) to the null device. This is
very fast, because the null device is virtual and does not require disk
writes. As a result the file (track) has been read once from disk and is
now in the linux disk cache.
On the OS level I could test and prove this really works! So all music
tracks now play from RAM memory, resulting in a more stable stereo
image. And yes that is very subjective ;-)
Maybe someone else likes to try this as well :-)
