Bespoke is a software modular synthesizer. It contains a bunch of modules, which you can connect together to create sounds.
Bespoke is like a DAW* in some ways, but with less of a focus on a global timeline. Instead, it has a design more optimized for jamming and exploration.
Bespoke is a project I started in 2011 as a way for me to learn more about creating music. Instead of putting in the time to learn the intricacies of an existing DAW, I took on a foolhardy exercise to try to build my own. The software is custom built by me and for me, hence the name "Bespoke".
Bespoke's core design is to break everything into separate modules that can be patched together in a custom layout, much like a hardware modular. Bespoke is designed to be highly customizable, with the idea that any of the custom layouts that you create will be "bespoke" to you as well.
In a way, Bespoke is like if I smashed Ableton to bits with a baseball bat, and asked you to put it back together.
Sonic Visualiser is a free, open-source application for Windows, Linux, and Mac, designed to be the first program you reach for when want to study a music recording closely. It's designed for musicologists, archivists, signal-processing researchers, and anyone else looking for a friendly way to look at what lies inside the audio file.

Carla is an audio plugin host, with support for many audio drivers and plugin formats. It has some nice features like automation of parameters via MIDI CC (and send output back as MIDI too) and full OSC control.
Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2/3 and AU plugin formats, plus GIG, SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA, DirectSound or CoreAudio.
There are 4 types of engine processing:
Single-client: (JACK driver only) Same as Multi-client, except that all JACK ports belong to a single master client. This is needed when a setup doesn't support multi-client JACK apps, such as LADISH. Multi-client: (JACK driver only) Every single plugin is exposed as a new JACK client. Audio and MIDI ports are registered as needed. Rack: Plugins are processed in order, from top to bottom. Plugins with non-stereo audio channels are not supported, but a forced-stereo option is available for Mono ones. Patchbay: Modular patchbay mode, just like in JACK Multi-client and many other modular applications. Every plugin gets its own canvas group and ports allowing you to interconnect plugin audio and MIDI.

Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented as an Audio Processing Object (APO) for the system effect infrastructure introduced with Windows Vista.
Features:
- virtually unlimited number of filters
- works on any number of channels
- very low latency, which makes it suited for interactive applications
- low CPU usage
- modular graphical user interface
Requirements:
- Windows Vista or later (currently only Windows 7, 8, 8.1 and 10 have been tested)
- Sound card driver must support APOs (this includes most onboard sound drivers)
- The application must not bypass the system effect infrastructure (APIs like ASIO or WASAPI exclusive mode can not be used)
A powerful software implementing a Spectrum Analyzer, Oscilloscope, Frequency meter, Distorsiometer, Volt meter and more... plus complete D/A conversion, ZRLC, Impedance meter
REW is free room acoustics analysis software for measuring and analysing room and loudspeaker responses. The audio analysis features of REW help you optimise the acoustics of your listening room, studio or home theater and find the best locations for your speakers, subwoofers and listening position. It includes tools for generating audio test signals; measuring SPL and impedance; measuring frequency and impulse responses; measuring distortion; generating phase, group delay and spectral decay plots, waterfalls, spectrograms and energy-time curves; generating real time analyser (RTA) plots; calculating reverberation times; calculating Thiele-Small parameters; determining the frequencies and decay times of modal resonances; displaying equaliser responses and automatically adjusting the settings of parametric equalisers to counter the effects of room modes and adjust responses to match a target curve.
You can read ARTA as; Audio Real Time Analysis.
ARTA software contains three programs:
- ARTA.EXE - program for the impulse response measurement, real-time spectrum analysis and frequency response measurements.
- STEPS.EXE - program for frequency response measurements with stepped-sine excitation. Simultaneously with a frequency response measurement the program estimates levels of 2nd, 3rd, 4th, 5th and higher order harmonic distortions.
- LIMP.EXE - program for the loudspeaker impedance measurement and loudspeaker parameters estimation.
ARTA has functions of following measurement systems:
- Signal generator of random and deterministic signals
- Impulse response measurement system
- Frequency response measurement system
- Fourier analyzer
- Spectrum analyzer
- THD analyzer
- Storage scope
With calibrated microphone, ARTA can be used as a virtual IEC class 1 SPL meter with a real time modes:
- Integrating SPL meter with 24 hours data logging,
- Octave SPL meter with noise rating (NR, NC, PNC, RC,NCB),
- Third octave SPL meter with report of loudness in sones and level in phones
ARTA is also a powerful analyzer of Gated impulse response, Smoothed frequency response (in 1/n-octave bands), Step response, Impulse response envelope (ETC – curve), Cumulative spectral decay waterfall graphs and sonogram, Burst decay waterfall graphs and sonograms, Energy decay in reverberant environments, Room acoustical parameters, Directivity patterns, Speech intelligibility measures: MTF, STI, STIPA, %AL.

ChucK is a programming language for real-time sound synthesis and music creation. ChucK presents a unique time-based, concurrent programming model that's precise and expressive (we call this strongly-timed), dynamic control rates, and the ability to add and modify code on-the-fly. In addition, ChucK supports MIDI, OpenSoundControl, HID device, and multi-channel audio. It's fun and easy to learn, and offers composers, researchers, and performers a powerful programming tool for building and experimenting with complex audio synthesis/analysis programs, and real-time interactive music.
Csound is a sound design, music synthesis and signal processing system, providing facilities for composition and performance over a wide range of platforms. It is not restricted to any style of music, having been used for many years in the creation of classical, pop, techno, ambient, experimental, and (of course) computer music, as well as music for film and television.
Csound 5 is the current version and its software architecture has been greatly redesigned, presenting a number of significant advantages over Csound 4 for both the user and for developers wishing to call Csound from their own software. Csound 5 supports the most popular operating systems in use today, including Linux, Mac OS X, and Windows. Csound 5 will also probably compile and run on other Unix-based systems. (Success has been reported with NetBSD). A package for MacOS 7-9 is updated from time to time as well.
Csound is now free software released under the GNU Lesser General Public License. It is developed by a community of volunteers and new contributors are welcome. Csound was originally developed by Barry L. Vercoe at the Music and Cognition Group of the M.I.T. Media Laboratory, with partial support from the System Development Foundation and from the National Science Foundation Grant #IRI-8704665
Friture is a program designed to analyze audio input in real-time.
