Bitcrusher in Logic Pro for iPad
Bitcrusher is a low-resolution digital distortion effect. You can use it to emulate the sound of early digital audio devices, to create artificial aliasing by dividing the sample rate, or to distort signals until they are unrecognizable.
To add Bitcrusher to your project, choose Distortion > Bitcrusher in a channel strip Audio Effect plug-in menu or the Plug-ins area. See Intro to plug-ins. Also see Add, replace, reorder, and remove plug-ins in the Plug-ins area and Work with plug-ins in the Mixer.
Bitcrusher parameters
Drive knob and field: Set the amount of gain applied to the input signal.Note: Raising the Drive level also tends to increase the amount of clipping at the effect output.
Clip Level knob and field: Set the point (below the clipping threshold of the track channel) at which the signal starts clipping.
Clip Mode buttons: Set the distortion mode to Clip, Wrap, or Fold. Signal peaks that exceed the clip level are processed.
Note: The Clip Level parameter has a significant impact on the behavior of all three modes. Try each mode and adjust the Clip Level value to get a feel for how this works.
Clip: Enable to cause an abrupt distortion when the clipping threshold is exceeded.
Wrap: Set a moderately severe distortion by offsetting the start, mid, and end levels of the signal above the threshold. This parameter smooths signal levels when they cross the threshold. The center portion of the clipped signal is softer than in Clip mode.
Fold: Set a softer distortion by halving the level of the center portion of the signal above the threshold. The start and end levels of the clipped signal are unchanged.
- Resolution knob and field: Set the bit rate (between 1 and 24 bits) to alter the calculation precision of the process. Lower values increase the number of sampling errors, generating more distortion. At extremely low bit rates, the amount of distortion can be greater than the level of the usable signal.
- Downsampling knob and field: Reduce the sample rate. A value of 1x has no effect on the signal, a value of 2x halves the sample rate, and a value of 10x reduces the sample rate to one-tenth of the original. For example, if you set Downsampling to 10x, a 44.1 kHz signal is sampled at just 4.41 kHz.
Note: Downsampling has no impact on the playback speed or pitch of the signal.
Mix slider and field: Set the balance between the dry and crushed signal.
