Shairport Sync is an AirPlay audio player – it plays audio streamed from iTunes, iOS, Apple TV and macOS devices and AirPlay sources such as Quicktime Player and ForkedDaapd, among others.
Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. In this way, synchronised multi-room audio is possible for players that support it, such as iTunes and the macOS Music app.
Shairport Sync runs on Linux, FreeBSD and OpenBSD. It does not support AirPlay video or photo streaming.
Skywave Linux is a 64 bit live system providing installed and configured software for accessing software defined radio servers locally and on the internet. With this operating system, a person may tune shortwave broadcasts, amateur radio, aeronautical, maritime, or other signals received at remote servers around the world.
SDR software is configured for popular devices, such as the RTL-SDR dongles, Softrocks, Hermes, and other radios.
Skywave Linux is a 64 bit system built over Ubuntu Linux, and may be installed on a bootable USB stick, SD card, DVD, or hard drive.

Project SWAMI, Sampled Waveforms And Musical Instruments, is a collection of free software for editing, managing and playing musical instruments for MIDI music composition. Current focus is primarily the SoundFont format, which is an open file format for digital audio “sample” based instruments.
Dynamic Audio Normalizer is a library for advanced audio normalization purposes. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. 0 dBFS). However, in contrast to more “simple” normalization algorithms, the Dynamic Audio Normalizer dynamically re-adjusts the gain factor to the input audio. This allows for applying extra gain to the “quiet” sections of the audio while avoiding distortions or clipping the “loud” sections. In other words: The Dynamic Audio Normalizer will “even out” the volume of quiet and loud sections, in the sense that the volume of each section is brought to the same target level. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying “dynamic range compression”. It will retain 100% of the dynamic range within each “local” region of the audio file.
The Dynamic Audio Normalizer is available as a small standalone command-line utility and also as an effect in the SoX audio processor as well as in the FFmpeg audio/video converter. Furthermore, it can be integrated into your favourite DAW (digital audio workstation), as a VST plug-in, or into your favourite media player, as a Winamp plug-in. Last but not least, the “core” library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface). The “native” API is written in C++, but language bindings for C99 Microsoft.NET, Java, Python and Pascal are provided.
Spek (IPA: /spɛk/, ‘bacon’ in Dutch) helps to analyse your audio files by showing their spectrogram. Spek is free software available for Unix, Windows and Mac OS X.
- Supports all popular lossy and lossless audio file formats thanks to the FFmpeg libraries.
- Ultra-fast signal processing, uses multiple threads to further speed up the analysis.
- Shows the codec name and the audio signal parameters.
- Allows to save the spectrogram as an image file.
- Drag-and-drop support; associates with common audio file formats.
- Auto-fitting time, frequency and spectral density rulers.
- Adjustable spectral density range.
- Translated into 19 languages.
- Most audio formats supported: MP3, FLAC, OGG, WMA, AIFF, etc.

This is a collection of tools to help you manage, maintain, and optimize your own music library for a better experience.
It makes growing and maintaining a music collection of any size easier by automating necessary (but tedious) processes.
The tools currently aim to assist with music organizing and tagging, and playlist management.
Cross-Platform Compatible – Works and tested under Linux (Ubuntu) and Windows. Mac untested but expected to work similar to linux.
