Aqualung 2.0, a music player, has been released. It provides an interface for playing audio CDs, local music collections, online radio stations, and podcasts. Aqualung features a gapless playback mode, allowing music files to be played in a continuous stream, with one track following the next without pause. The project's code is written in C and is licensed under the GPLv2 license. It supports Linux, FreeBSD, OpenBSD, Windows ΠΈ macOS.
Among the advanced features of Aqualung, another highlight is the ability to increase or decrease the sampling frequency of the file being played before sending the audio stream to the audio output device. LADSPA plug-ins can be connected to apply effects, improve the quality and process the sound. For example, you can use plug-ins with different implementations of equalizers, spatial sound optimizers and tube preamplifier simulators.
The key change in Aqualung 2.0 was the transition of the application from GTK2 to the GTK3 branch. CSS was used to design the interface. The ability to use previously prepared skins to change the interface was discontinued. An option to switch between light and dark themes was added to the settings. Support for new versions of the Monkey's Audio format for encoding audio without loss of quality was added. The number of supported formats in the FFmpeg-based decoder was expanded.
