Effects.DistortionApply method

Previous pageReturn to chapter overviewNext page

Remarks

 

Applies a distortion effect to the given portion of sound under editing.

 

Similar to Pre/Post Gain & Drive controls on amps. They were first introduced as a trick to added color to a guitar's tone. Usually produced back then by turning the amp all the way up, or slightly pulling out a tube from its socket. These tones are now today referred to as Overdrives. Today, there are an almost infinite variety of these effects, and they range in 3 classes: Distortions, Fuzz, and Overdrive. One common feature to mostly all of these types of pedals is a volume and drive (also noted as distortion, fuzz, gain, ...etc.). Overdrives are usually a sustain and volume boosting pedal. Used by more traditional rock and country bands. Next are the Distortions, which range from punk style to death metal screams. They are similar to Overdrives, but have more buzzing quality to them. Finally, there are the Fuzzes which are more distorted than distortions, but are more mellow and compressed sounding. Many pedals can be confused within these names, and some may be named other than what they are. Towards the end of this era, the back-to-back diode pair became popular as a technique to provide soft clipping (with germanium diodes) and hard clipping (with silicon diodes). Today, overdrive effects usually means soft clipping, where gain is reduced beyond the clipping point, while distortion usually means hard clipping, where the level is fixed beyond the clipping point. Distortion is a little harder sound, good for rock, while overdrive gives a more natural sound.

 

A successful call to this method will fire the SoundEditStarted event followed by a number of SoundEditPerc events and finally by the SoundEditDone event.

Parameter

Description

 

 

nStartPosition

Start position, expressed in milliseconds, of the affected sound range.

nEndPosition

End position, expressed in milliseconds, of the affected sound range.. If set to -1 the end position will be set to the end of the sound.

nAffectedChannel

Numeric value that determines the combination of affected channels.

Supported values are the following:

CHANNEL_MASK_7

128 (0x80)

Channel 7

CHANNEL_MASK_LEFTS

85 (0x55)

All left channels

CHANNEL_MASK_RIGHTS

170 (0xAA)

All right channels

CHANNEL_MASK_ALL

255 (0xFF)

All available channels

fDrive

Numeric value representing the distortion drive.

Supported values are in the range from 0 to 5.

fDryMix

Numeric value representing the Dry (unaffected) signal mix.

Supported values are in the range from -5 to +5.

fWetMix

Numeric value representing the Wet (affected) signal mix.

Supported values are in the range from -5 to +5.

fFeedback

Numeric value representing the output signal to feed back into input.

Supported values are in the range from -1 to +1.

fVolume

Numeric value representing the distortion volume.

Supported values are in the range from 0 to 2.

 

The fDrive controls the amount of overdrive. The fVolume to balance the effect volume with the bypassed level. It can also be used to boost the signal for solos. The fDryMix is the volume of input signal and the fWetMix is the volume of distorted signal. The fFeedback sets feedback of distortion.
