DtBlkFx by Darrell Barrell

DtBlkFx is a Fast-Fourier-Transform (FFT) spectral processing plug-in.

Features:

Precision parametric equalizing with sharp-roll off:

• Set the frequencies so accurately that you can adjust individual harmonics of a sound.
• Frequency resolutions of up to 0.7 Hz.

Harmonic based (or comb) filtering:

• Set a fundamental frequency and adjust the level of it and its harmonics – you can even remove the pitched component of a voice.
• Active harmonic tracking – let DtBlkFx automatically track a sound and adjust the level of its harmonics.

Various types of noise control:

• Change the “contrast” between loud and soft frequency components.
• Adjust only those frequencies below or above a particular threshold.
• Clip frequencies above a particular threshold.
• Sound smearing (phase randomizing).

Frequency shifting:

• Harmonic shifting by a fixed number of notes.
• Non-harmonic shifting by a fixed frequency.
• Active harmonic repitch – the content of your sound is monitored and re-pitched to a destination note.

Vocoding:

• Standard (frequency enveloping) – make your trumpet rap, string section sing or synthesizer talk.
• Harmonic based – harmonics in one channel are power-matched to those in the other (or some predefined waveforms) for a new vocoding sound.

Frequency masking:

• A harmonic or threshold mask may be set for any effect (apart from vocoding) – for example only shift frequencies that are below the threshold.

Realtime spectrogram (waterfall) display of input and output sounds:

• See what frequency components are in your sound and exactly what you’ve done.
• Use your mouse to see the note & frequency under the pointer.

You can select up to 4 of the above effects to be run in series – combining the effects in this way allows you to make completely new and surprising sounds.
