This is a fork of the original DtBlkFx by Darrell Tam. The original source was

not ready for public consumption. I have spent a considerable amount of time

getting this ready for a Github release.

Despite a major overhaul of the project structure, I have only made very small

changes to the source itself to enable x64 builds on windows. There is still a

long way to go to making it clean and easy to hack on.

That being said, anyone with a reasonable amount C++ experience shouldn't find

it too difficult to get started. I am glad to accept pull requests and any other

help I can get.

## Usage examples

* 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 it's harmonics

* Various types of noise control

    * Change the "contrast" between loud and soft frequencies

    * 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 pitch of your sound is monitored and shifted

      to a destination note (or matched to another channel)

* Various methods of mixing left and right channels

    * Standard Vocoding (frequency enveloping) - make your trumpet rap, string

      section sing or synthesizer talk

    * Harmonic based vocoding - harmonics in one channel are power-matched to

      those in the other (or some predefined waveforms) for a new vocoding sound

    * Convolution-like mixing

    * 2 new mixing algorithms

* 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

You can select up to 8 of the above effects to be run in series! Combining the

effects in this way allows you to make completely new and surprising sounds.
