Elisa is a music player developed by the KDE community that strives to be simple and nice to use. We also recognize that we need a flexible product to account for the different workflows and use-cases of our users. We focus on a very good integration with the Plasma desktop of the KDE community without compromising the support for other platforms (other Linux desktop environments, Windows and Android). We are creating a reliable product that is a joy to use and respects our users privacy. As such, we will prefer to support online services where users are in control of their data.

FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra.
It is an extremely addictive audio toy, but I hope it has value for serious audio work too (sound design, etc). The spectrum analysis is pretty useful in its own right.

TASCAM Hi-Res Editor is a new, free application for Windows and Macintosh computers, that plays and edits up to 11.2MHz DSD or 384kHz WAV files.

Playtime is a FREE premium VST created by Daniel of Reflekt Audio. Playtime consist of ten different toy instruments that range from a desktop drum kit with a few toms and a hi hat, to a toy keyboard, a toy banjo, and more! The Playtime VST plugin has multiple blend-able microphones that the user can blend together to create one overall tone. Each instrument was sampled from real toys so you can bet on a unique and interesting toy like sound.

A software synthesizer intended for use with DTM software. Supports VSTi plug-in / AU plug-in format. This software is freeware. Functionally, it is modeled after the red synth Clavia NORD LEAD2 and has the following features:

This software allows “scratching” on digitally sampled audio data (*.wav, *.au, *.ogg, *.mp3, etc.) the way hip hop DJs scratch on vinyl records. It features multiple turntables, realtime effects (built-in as well as LADSPA plugin effects), a sequencer and MIDI interface – all accessible through an easy-to-use gtk+ GUI. This software is designed to run under Linux, FreeBSD and the like.
