I'm testing wavinput on my PiCoreplayer setup, here's a couple of things
I did to make it work + a question
It worked pretty much first time, once I installed and configured the
local LMS on the PiCoreplayer + wavinput plugin as wavin:default.
I'm using an ancient USB Soundblaster MP3+ which works fine as a player,
and might approximate a low-end sound card these days.
But it produced horrible dropouts when capturing audio.
Eventually, having tried a few things, I fixed it by changing the sample
rate from 44100 to 48000
So the command in
/mnt/mmcblk0p2/tce/slimserver/Cache/InstalledPlugins/Plugins/WaveInput/custom-convert.conf
becomes
Code:
--------------------
[arecord] -d0 -c2 -f S16_LE -r 48000 -twav -D $FILE$ | [flac] -cs
--totally-silent --compression-level-0 -
--------------------
A nice simple fix in this case, no apparent dropouts, of course YMMV.
The other thing I found was that the PCP didn't seem to load my saved
Alsamixer settings which default to the MIC as input - no good.
Setting the input to line and setting a suitable level, then 'sudo
alsactl store' saves asound.state in /var/lib/alsa
Setting user startup command #1 to 'sudo alsactl restore' does the trick
of always restoring input levels & routing.
So the question -
I'm using this setup to rip some vinyl, but having difficulty in
capturing the stream. Local capture isn't practical on the PCP due to SD
card size, location etc, and the suggestion is that Squeezelite can save
to file by redirecting output (-o -). However when I do this I get a
huge file very quickly, that nothing recognizes, not even Audacity. I'm
assuming it's FLAC or raw audio and tried piping it through ffmpeg, but
it doesn't like it either. Any suggestions ? Thanks
