Decibel Audio Player
1.
Introduction
What's Decibel?
From the homepage: Decibel
Audio Player is a GTK+ open-source (GPL license) audio player designed for
GNU/Linux, which aims at being very straightforward to use by means of a very
clean and user friendly interface. It is especially targeted at Gnome and will
follow as closely as possible the Gnome HIG.
Decibel is a nifty, simple little app. It has as much playback functionality as
you want it to have. It's not an audio Swiss Army knife; for that, take a look
at Banshee, Exaile, or Amarok. It's intended for easy browsing and playing of your
music collection. It supports several audio formats and CD playback, and can
keep track of several different music library locations. (A nice improvement
over other audio applications that track only one library).
Decibel mostly uses Python, gtk+, and gstreamer, though it also needs a few
Gnome libraries. It should still be lightweight even if you don't use Gnome. If
you do use Gnome, it will be fully integrated into your desktop.
Decibel has optional additional runtime integration with various Gnome libraries
such as gnomeprint, gtksourceview, wnck, gnome-applets, gnome-media,
totem-pl-parser, and a few others. More on this later.
Why here? Why not on some overlay collection site?
Because I want to keep it here, that's why. It's much better for development to
keep it with the rest of my stuff.
Final warning
Decibel is not yet in the Portage
tree. Hopefully this will change, but for now, it means that you get to pick up
the pieces if it breaks.
Whatever you do, don't complain to the Gentoo developers if something breaks or
doesn't work the way you wanted to. Remember, this is unsupported. That being
said, if there's a technical issue that pops up with the
decibel-audio-player ebuild, Manifest, etc., email me and I'll take a
look.

Gimme!
For Gentoo users
First, download the latest version of
decibel-audio-player. Drop it into
${PORTDIR_OVERLAY}/media-sound/decibel-audio-player/. It's marked
~arch, so you'll need to keyword it in
/etc/portage/package.keywords before installing.
Code Listing 2.1: Keywording Decibel |
# echo "media-sound/decibel-audio-player" >> /etc/portage/package.keywords
# echo "media-plugins/gst-plugins-meta" >> /etc/portage/package.keywords
|
Next, let's take a look at the available USE flags. Since Decibel uses the
modular gstreamer framework, you can choose the kinds of audio formats you want
to be able to play. Decibel currently supports WMA (via ffmpeg), mp4 (aac), mp3,
FLAC, Musepack, and Ogg Vorbis.
Here are the USE flags available for the Decibel ebuild:
| USE flag |
Description |
| aac |
Enables support for MPEG-4 AAC audio (mp4) |
| cdaudio |
Adds support for CD audio playback and lookups via CDDB |
| gnome |
Enables additional integration with the Gnome desktop |
| libnotify |
Enables desktop notification on track change. You'll get a customizable
little popup window.
|
| musepack |
Enables support for the Musepack (mpc) audio codec |
Decibel's ebuild depends on gst-plugins-meta, a metapackage that provides
most of the audio codecs. You can add support for the desired codec by
activating the appropriate USE flag for gst-plugins-meta:
| USE flag |
Description |
| ffmpeg |
Adds support for audio formats that use the ASF container, such as
Windows Media Audio (WMA)
|
| flac |
Adds support for FLAC: Free Lossless Audio Codec |
| mad |
Adds support for mp3 playback via MAD, a high quality decoder library
|
| vorbis |
Adds support for the Ogg Vorbis (ogg) audio codec |
You can set your desired USE flags globally in /etc/make.conf, or
locally in /etc/portage/package.use. For example, to enable support
for everything but Musepack, you could do the following:
Code Listing 2.2: Setting USE flags in package.use |
# echo "media-plugins/gst-plugins-meta ffmpeg flac mad vorbis" >> /etc/portage/package.use
# echo "media-sound/decibel-audio-player -musepack aac cdaudio gnome libnotify" >> /etc/portage/package.use"
|
Once your flags are set, install Decibel:
Code Listing 2.3: Installing Decibel |
# emerge -avt decibel-audio-player
|
One thing Decibel doesn't do is edit tags. Its creators believe such
functionality is best provided by dedicated tag editing applications. Remember,
Decibel focuses on being a real audio player focused on playback. There
are plenty of other tagging apps
available, such as TagTool.
For everyone else
If you're not running Gentoo, it's possible your distribution already provides
packages. Debian and Ubuntu have
have .debs available.
Otherwise, you can compile Decibel from source by following the instructions.
Be sure to note the dependencies. However, you should also take a look at my
ebuild to get a better idea of what's also needed.
