# musicomp
|
||
|
|
|
||
|
|
A simple music compression tool.
|
||
|
|
|
||
|
|
If you're anything like me, you obtain music in FLAC format for archival and compress it down to a codec such as Opus for actual listening.
|
||
|
|
musicomp exists to automate the continuous compression work that would otherwise have to be done manually.
|
||
|
|
|
||
|
|
It:
|
||
|
|
|
||
|
|
* scans the source and destination directories,
|
||
|
|
* makes sure the content is properly synchronized (i.e., there are no tracks in destination that don't exist in source and vice versa), and
|
||
|
|
* compresses the music from FLAC to Opus in parallel.
|
||
|
|
|
||
|
|
## Dependencies
|
||
|
|
|
||
|
|
musicomp requires `opusenc` in `$PATH` in order to function.
|
||
|
|
The Nix package wraps musicomp to include `opusenc` out of the box.
|
||
|
|
|
||
|
|
## NixOS
|
||
|
|
|
||
|
|
A NixOS module is provided within this flake.
|
||
|
|
Here's an example of how to use it:
|
||
|
|
|
||
|
|
```nix
|
||
|
|
{
|
||
|
|
self,
|
||
|
|
lib,
|
||
|
|
pkgs,
|
||
|
|
...
|
||
|
|
}: {
|
||
|
|
services.musicomp.jobs.main = {
|
||
|
|
music = "/srv/music";
|
||
|
|
comp = "/srv/compmusic";
|
||
|
|
timerConfig = {
|
||
|
|
OnCalendar = "daily";
|
||
|
|
Persistent = true;
|
||
|
|
};
|
||
|
|
inhibitsSleep = true;
|
||
|
|
post = let
|
||
|
|
remoteDir = "/my/music/folder";
|
||
|
|
rsyncExe = lib.getExe pkgs.rsync;
|
||
|
|
rsh = "${lib.getExe pkgs.openssh} -i /etc/ssh/ssh_host_ed25519_key -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null";
|
||
|
|
in ''
|
||
|
|
${rsyncExe} \
|
||
|
|
--archive \
|
||
|
|
--recursive \
|
||
|
|
--delete \
|
||
|
|
--update \
|
||
|
|
--mkpath \
|
||
|
|
--verbose --verbose \
|
||
|
|
--exclude lost+found \
|
||
|
|
--rsh ${lib.escapeShellArg rsh} \
|
||
|
|
/srv/compmusic/ root@my.server:${remoteDir}
|
||
|
|
'';
|
||
|
|
};
|
||
|
|
}
|
||
|
|
```
