the wahwactor
Description
The Wahwactor is a two-input and one-output system. Out of the two input tracks, one of the tracks may be considered a control rather than a proper input since it is the one in charge of driving the transformations to be applied to the audio signal. In the context of the Wahwactor, the audio signal is typically a guitar signal and the control signal is a voice [wa-wa] utterance signal.
First, the voice signal is analyzed to pick up a meaningful descriptor that, after a simple conversion (shift, scale and smooth), is used as the centre frequency of the wah-wah filter, through which the guitar signal is sent to be mixed with the original.
To work in real-time, the Wahwactor uses a frame-by-frame algorithm described by the diagram illustrated in Figure 4. The voice signal is sampled at 44100 Hz and analyzed using a 2100 sample Hamming window and a 2048 point Fast Fourier Transform. The guitar signal is sampled at 44100 Hz and filtered using 2100 sample length buffers. The algorithm uses a 1050 sample hop size so that we have a 50% overlap in synthesis. This overlap is necessary to smooth the filter phase frame to frame variations ...

WAHt:
VST Plugin Wah pedal emulation
Designed to be placed before an amp simulator and controlled with a Midi
continuous controller padal in real time. For an auto Wah use Auto Midi CC
to control the wah knob.

Wah_ml
Not really a wah emulation, just a great moog ladder filter set up to be
used in real time like a wah. Has controls for top and bottom level of
the filter cutoff (0-10) so you can set the cutoff range.

Autowah:
Un autowah simple et performant à deux LFOs pour créer des effets stéréos et ping pongs sonores. Efficace avec des sons riches (leads juteux et Saws/Squares), ou discret sur une guitare en arpèges.La configuration est facilitée par la visualisation en temps réel des valeurs des oscillateurs. Les deux composantes sont visibles séparément. Le plugin se présente visuellement comme un effet de guitare et fonctionne très bien avec une strat' :). L'appui sur le switch 'Autowah' bypasse ou pas l'effet, comme sur une 'vraie' pédale d'effet.
Le filtre utilisé est un lowpass du sixième ordre commandé en stéréophonie par deux oscillateurs basse fréquence, agissant sur la fréquence de coupure. La résonnance est paramétrable par la commande Res.
Le premier LFO est tres basse fréquence et dédié aux variations lentes. Le second (Pan), permet de moduler les variations du premier, afin de créer selon volonté un effet stéréphonique (switch Pan).
Le Mix final entre wet et dry ajuste le volume entre le son Autowah pur, ou unmélange équilibré entre les deux. L'appui sur le bouton de la pédale switch entre bypass et effet actif.
