Giada is a free, minimal, hardcore audio tool for DJs, live performers and electronic musicians. How does it work? Just pick up your channel, fill it with samples or MIDI events and start the show by using this tiny piece of software as a loop machine, drum machine, sequencer, live sampler or yet as a plugin/effect host. Giada aims to be a compact and portable virtual device for Linux, Mac and Windows for production use and live sets.
FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications and has reached widespread distribution. FluidSynth itself does not have a graphical user interface, but due to its powerful API several applications utilize it and it has even found its way onto embedded systems and is used in some mobile apps.
Features:
Cross platform support (Linux, macOS and Windows to name a few)
SoundFont 2 support
SoundFont 3 support (vorbis-compressed SF2)
Realtime effect control using SoundFont 2.01 modulators
Playback of MIDI files
Shared library which can be used in other programs
FluidPatcher is a performance-oriented interface for FluidSynth built using wxpython to create a simple GUI that allows live editing, selecting, and playing of patches. A patch is a collection of settings such as soundfont presets for each MIDI channel, control-change/sysex messages to send when the patch is selected, and midi router or effects settings. Groups of patches are stored in banks, which are saved as human-readable and -editable YAML files. This allows a musician to easily create complex combinations of synthesizer settings ahead of time and switch between them on the fly during a performance.
Features:
Live playing: Play on your MIDI controller and hear the results
Customization: Create your own combinations of instruments/effects
Extendability: Use the included libraries to design your own implementations/software
eSpeak is a compact open source Linux and Windows speech synthesizer for English and other languages. eSpeak uses a “formant synthesis” method. This allows many languages to be provided in a small size. The speech is clear, and can be used at high speeds, but is not as natural or smooth as larger synthesizers which are based on human speech recordings.
eSpeak is available as:
A command line program (Linux and Windows) to speak text from a file or from stdin.
A shared library version for use by other programs. (On Windows this is a DLL).
A SAPI5 version for Windows, so it can be used with screen-readers and other programs that support the Windows SAPI5 interface.
eSpeak has been ported to other platforms, including Android, Mac OSX and Solaris.

DFasma is free open-source software which is used to compare audio files in time and frequency. The comparison is first visual, using waveforms and spectra. It is also possible to listen to time-frequency segments in order to allow perceptual comparison. It is basically dedicated to analysis. Even though there are basic functionalities to align the signals in time and amplitude, this software does not aim to be an audio editor.
Features:
Can load about 25 different audio formats (thanks to libsndfile or libsox).
Shows spectrogram, amplitude, phase spectra and group delay.
Can play a filtered sound given a selected frequency band.
Rectification of the spectrogram tilt (cepstral lifting).
Can create and edit segmentation files.
Can create and edit fundamental frequency (F0) files (thanks to REAPER).
Meson Player is a very convenient music player if you don’t need a GUI to control playback or manage playlists. You just run it and then forget about it. The player runs in the background. Switching tracks, volume control, loading and saving playlists, all of this is performed by using hotkeys, therefore you can control the player while working in any application.
Meson Player supports gapless playback, Last.FM, a lot of music file formats (stream and tracker), Internet radio and playlist management.
