Great article :)

Maybe you could mention flack, which is a command line tool for editing FLAC files:


I find it really useful.

Thanks for the suggestion. I’ll give it a try, and maybe it will go in the next revision of the guide, especially since it’s command-line.

Nice job on the guide. abcde is an awesome tool for ripping CD’s. I’d just like to mention a few posts on by blog about converting audio with GStreamer.


The big advantage to using GStreamer to do the conversion is that if you have your high bitrate files tagged, when you convert or down-sample them, GStreamer automagically takes care of the tagging for you. So if you archive your music in FLAC and want to convert to medium quality Ogg Vorbis or MP3, your new files will be properly tagged. I believe that GStreamer has plugins to handle all the formats you listed above.

I like the Iron Maiden reference. :->

Craciun Dan says:

Thank you!

I’ve never used GStreamer before for converting between files, I’ll give it a try, thanks for the links, I’ll find some time to try these two tutorials.

And yeah, up the irons :)

After using this guide for the past 2 years, finally found something that you can improve on

wma to flac/wav conversion

ogg to flac/wav conversion

Laurencio says:

Hello. I want to convert .flac files to .ogg.
Following this guide i’ve installed vorbis-tools and flac.

then when i type the following command line “oggenc Track01.flac -q 6 -o Here_to_stay.ogg”

i get the this error message:

ERROR: El fichero de entrada “Track01.flac” no está en ningún formato soportado.

Craciun Dan says:

Try to first convert the FLAC file to WAV and then the WAV to Ogg.
