Qsynth ~ Fluidsynth Qt GUI


Qsynth is a fluidsynth GUI front-end application written in C++ around the Qt framework using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynth but for the moment it wraps the excellent FluidSynthFluidSynth is a command line software synthesiser based on the Soundfont specification.

Voxengo Boogex


Applications

  • Real-time guitar processing
  • Speaker cabinet simulation
  • Stereo convolution processing
  • Guitar reverb effect

Boogex is a free guitar amplifier AudioUnit, AAX, and VST plugin with a variety of sound shaping features, for professional sound and music production applications.  With Boogex it is possible to get a heavy distorted sound as well as slight “jazzy” saturation sound.  Boogex is able to apply convolution with any speaker cabinet impulse response (selection of built-in impulses is available).  The processing latency is close to zero making it possible to use Boogex for real-time guitar processing.

Boogex can be used as a plain stereo convolution processor when its “Amp” stage is turned off.  The convolver module has zero latency and is not CPU-demanding.  Boogex also includes the input gate module, and reverberation module derived from Voxengo OldSkoolVerb reverb plugin.

Boogex produces a nice “minimalist” rock music-geared sound which may be a bit noisy at higher overdrive settings; higher frequencies can be easily suppressed with its built-in Emphasis EQ.  With the amp modes Boogex currently provides, it is not particularly well-suited for metal music, but can still be used as a cabinet impulse response processor for metal music.

Overtone GEQ ~ Harmonic Graphic Equalizer


Overtone GEQ is a free 7-band harmonic (overtone) graphic equalizer AudioUnit, AAX, and VST plugin with multi-channel operation support (supporting up to 8 input/output channels, audio host application-dependent).  Overtone GEQ offers extensive internal channel routing capabilities, and supports mid/side channel processing.

Beside equalizing, Overtone GEQ applies harmonic enhancement: it uses 7 harmonic enhancement modules, one for each EQ band.  This generates a complex harmonic coloration you will probably like a lot.

Overtone GEQ was designed to allow audio engineers to apply quick EQ shape adjustments together with adding a bit of harmonic richness to the audio material (mainly mixes and sub-mixes due to a comparably high load this EQ puts on a CPU).

Wigware Ambisonic Decoder (WAD)


Wigware Ambisonic Decoder (WAD)

This program now comes in two flavours, as a Direct Show filter and a VST plugin. The Direct Show Filter allows any Direct Show capable audio player software (such as Windows Media Player) the ability to read and decode B-format wave files (the format of which is specified here on Richard Dobson’s web page – details on the Waveformat extensible file format used can be found on Microsofts web site here – details on Ambisonics can be found here).

The VST version comes in 1st and 2nd order versions (3rd and 4th order versions to follow) and allows you to alter the polar patterns of the speaker feeds either across the whole frequency range or using ‘Shelf Filters’ with a variable cut-off. Both of the VST plugins will derive outputs for a standard ITU 5 speaker array, with higher orders giving better frontal resolution.
