foo_dsp_xover ~ Foobar2000 Digital Crossover


foo_dsp_xover is a software digital crossover implementation that I have been working on for a while in my spare time as a hobby. It is a Foobar2000 audio player plugin that implements this digital crossover to achieve active multi-amplification.

This software needs to run on a WinXP PC equipped with a multi-channel sound card (e.g. 5.1 or 7.1 surround sound card) feeding the various voices of a multi-amplifier and loudspeaker active configuration set-up.

Pulseaudio ~ Crossover Rack


Pulseaudio Crossover Rack is a program to design and implement multi-way speaker crossovers using any linux powered computer with a multi-channel sound card and a running desktop environment which uses Pulseaudio as it’s sound backend. It also uses a set of LADSPA plugins, namely ladspa-t5-plugins for the heavy lifting of DSP/audio processing. It’s written in python3 and uses QT as the windowing toolkit.

freeDSP ~ DIY Audio DSP Project


The freeDSP is an open-source digital signal processor family for the do-it-yourself community. The applications range from active loudspeaker concepts (digital crossovers, bass enhancement, …) and room equalization over advanced musical effect processors to car audio signal processing.

rePhase ~ Loudspeaker Phase Linearization


rePhase is a FIR generation tool for building fully linear-phase active crossovers with arbitrary slopes.

It also let you manually compensate for the phase shifts of your loudspeakers and existing crossovers, be it active or passive.

Once generated, the FIR can be applied using any hardware (openDRC, miniSHARC, Najda, …) or software (foobar, convolver, JRiver, …), stereo or multi-way convolution engine.
