Stronger effects can be achieved by applying the algorithm multiple times, which can be achieved by setting the "Repeat processing" control greater than 0. One limitation of this type of distortion is that even when applied fully, the effect is still quite mild.
This implementation does not use oversampling, though oversampling can be applied manually by resampling the track to a higher rate prior to applying this distortion effect. This shaping function is often used in electric guitar distortion effects as it is possible to avoid aliasing distortion with only a modest amount of oversampling. Note that even without "Make-up Gain", the output level may be higher than the clipping threshold because the peaks are in effect 'squashed' flatter rather than being completely cut off. When set to 100, the amplification is such that an input level of 0 dB (full track height) will produce an output level of 0 dB. Make-up Gain (0 to 100): When set greater than 0, the output from the effect is amplified.Hardness (0 to 100): The 'hardness' of the clipping (100 % being "hard").The slider control has a logarithmic scale to allow settings close to 0 dB to be made more easily and accurately. Clipping threshold (-100 to 0 dB): The level at which gain reduction (clipping) starts.The softer the clipping, the more rounded the clipped peaks and the less risk of aliasing distortion. This is achieved by progressively reducing the gain when the input is above the clipping threshold. This type of distortion is similar to Hard Clipping except that 'corners' where clipping intersects with the waveform are rounded.
