Bluemindo is a really simple yet powerful audio player in Python/PyGTK, using Gstreamer. It’s a free (as in freedom) software, released under GPLv3, only.
Bluemindo’s user interface consists of a main view of all your digitized album discs, which is searchable and filterable. The playback mode is gapless and support ReplayGain (it can also automatically choose to switch between Album and Track modes, depending on the kind of music that’s being played). Last but not least, it brings playlist (automatic and user-made), MPRIS/MediaPlayer2 support and lyrics/artwork downloading.

Decibel Audio Player is a GTK+ open-source (GPL) audio player for GNU/Linux. It is very straightforward to use thanks to a clean and user-friendly interface. It is especially targeted at Gnome and follows the Gnome HIG.
Decibel Audio Player is built around a highly modular structure that lets the user disable completely the features he does not need. A disabled feature uses absolutely no memory and no processor time.
Decibel Audio Player is a real audio player and does not include features that are not meant to be part of an audio player. These features, such as tagging files or burning CDs, generally have a better support in dedicated software. If you are looking for an audio player that can make coffee, then you should stay away from Decibel and give a try to other players (e.g., Amarok, Exaile).
LINGOT is a musical instrument tuner. It’s accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments.
It looks like an analogue tuner, with a gauge indicating the relative shift to a certain note, determined automatically as the closest note to the estimated frequency.
- It’s free software. LINGOT is distributed under the GPL license.
- It’s really quick and accurate, perfect for real-time microtonal tuning.
- Easy to use. Just plug in your instrument and run it.
- LINGOT is a universal tuner. It can tune many musical instruments, you only need to provide the temperaments. For that purpose, it supports the Scala project .scl format.
- Highly configurable via GUI. It’s possible to change any parameter while the program is running, without editing any file.
