Waveform Effects

You can apply effects to waveforms in the current Sphere. There are four traditional effects (Wavefolding, Bit

Decimation, Metalizer, and Low Pass Filter) and two utility effects (Gain/Normalization and Seam Smoothing).

Each of the top row of buttons is assigned to an effect:

Wavefolding

The waveform is distorted and folded back on itself, creating harmonics of the fundamental waveform.

Bit Decimation

The allowable sample values are quantized, creating the same effect as if the recording was made at a low bit-

rate (e.g. 12-bit, 8-bit, 6-bit, 4-bit, etc). The effect amount controls the simulated bit rate.

Metalizer

Feedback through a high-pass filter is simulated, creating harsh, higher harmonics.

Low Pass Filter

A non-resonant brick-wall low pass filter is applied to the signal, filtering out any higher harmonics. The effect

amount controls the cut-off frequency.

Gain/Normalization

From 0% to 50%, this effect controls the attenuation of the waveform. At 0%, the waveform is silence; at 50%, no

change will be made to the amplitude. From 50% to 100% normalization will be applied. This means the gain will

be increased as much as possible without clipping. If the waveform is already at its maximum amplitude, then

increasing this effect from 50% to 100% will have no effect.

Gain/Normalization

is set to 50% when you first

enter Sphere Recording Mode (meaning that the amplitude of all waveforms is unaltered). When a recording is

finished, the effect is automatically set to 100% (meaning all waveforms are brought to their maximum amplitude).

Seam Smoothing

When splitting up a live audio recording into waveforms, the last sample value of the waveform might not always

line up with the first sample value. This creates a harsh sound when played, even if the waveform itself is

something simple and pure (like a sine wave).

Seam Smoothing

takes the audio data that follows the recorded

waveform and cross-fades it back into the original waveform, creating a seamless loop. Since waveforms are

almost always repeated in live audio, taking some data from the next waveform usually introduces no extra

sounds that what was originally recorded.

You can apply an effect to waveform(s) in several ways:

Applying an Effect to a Single Waveform

If you hold down one of the effect buttons and turn the

Browse

knob, the effect is applied to the current

waveform. The light ring will display a number of lights to indicate how much effect is currently being applied to

the waveform.

Applying an Effect to a Dimension of Waveforms

Holding down an effect button while turning

Depth, Latitude,

Longitude

will apply the effect to the three

waveforms located in the chosen dimension of the current waveform. For instance, if you browse to the first

waveform and then hold an effect button while turning

Longitude

, the effect will be applied to all three waveforms

that have the same

Depth

and

Latitude

as the first waveform

but vary in

Longitude.

If the effect has already

been applied to any individual waveform in the dimension, the effect level will be offset by the new amount.

Applying an Effect to All Waveforms

To apply an effect to all 27 waveforms, hold down the effect button as you push and turn the

Browse

knob. If the

effect has already been applied to any individual waveform, the effect level will be offset by the new amount. You

can clear the effect amount on all waveforms by first increasing the effect level on all waveforms to maximum, and

then reducing it to minimum.
