How to convert .mp3 to .ogg in Solus

Solus OS has pre-installed ffmpeg application, which is a powerful tool not only for formatting video, but also for audio formatting too.

First, let's see, what we have:

$ ls
'Frederic Chopin - Nocturne In C Sharp Minor.mp3'

One .mp3 file. And our goal is to convert it to .ogg format.

In order to convert .mp3 file to .ogg, just run following command:

$ ffmpeg -i 'Frederic Chopin - Nocturne In C Sharp Minor.mp3' -c libvorbis Chopin-Nocture_in_C_sharp_minor.ogg

output:

Moreover, let's check size of an original file and converted one:

dima@edustorage ~/Downloads $ ls -l
total 8504
-rw-rw-r-- 1 dima dima 2850749 Apr 26 13:05  Chopin-Nocture_in_C_sharp_minor.ogg
-rw-r--r-- 1 dima dima 5854491 Apr 26 12:29 'Frederic Chopin - Nocturne In C Sharp Minor.mp3'

You see: .ogg file is almost twice as small as original one :)
