Decompose Page

The Decompose function allows you to split your samples into their noise and tonal components. This allows you to edit the tonal and the noise components of your samples separately, for example, to change the distribution between the noise and tonal portions of a sample.

Prelisten

Calculates the tonal and noise components of your sample according to the current settings. This allows you to prelisten your Decompose settings.

  • If Solo Tonal or Solo Noise is activated, you hear the tonal or the noise components of the layer.

  • If Mix is activated, you hear the mix that you adjust with the Tonal Level and Noise Level controls.

Apply

Applies the Decompose function.

Note

  • If Mix is activated, this replaces the sample.

  • If Solo is activated for the tonal or the noise components, only this component replaces the sample in the layer.

  • If Mix and Solo are both deactivated, two new layers are created, one for the tonal and one for the noise component of the sample.

Sensitivity

Allows you to specify the level difference that is required between the signal partials and the noise floor. The value you specify defines the minimum distance between the peaks and the troughs of the spectrum for a partial to be detected. If you lower this value, more signal portions of the sample are considered to belong to the tonal component.

Cutoff

Allows you to define the upper limit of the range in which HALion searches for partials. Any signals above the Cutoff frequency are considered as noise, regardless of the Sensitivity or Duration settings.

Duration

Allows you to specify the minimum length for a partial. Signals that are shorter than the value specified are automatically considered as noise; longer signals are considered as belonging to the tonal component.

You can try to lower this setting if you work with samples that have fast attacks or strong transients which were not detected correctly by the Decompose function.

Tonal Level

Allows you to adjust the level of the tonal component.

Activate Solo Tonal to listen to the tonal component only.

Note

Make sure that Solo Tonal is deactivated when you click Apply. Otherwise, the layer is overwritten with the tonal component of the sample.

Noise Level

Allows you to adjust the level of the noise component.

Activate Solo Noise to listen to the noise component only.

Note

Make sure that Solo Noise is deactivated when you click Apply. Otherwise, the layer is overwritten with the noise component of the sample.

Mix

If this is activated, you can modify the mix with the Tonal Level and Noise Level dials and save the adjusted mix as a new file.

Create Layer

Allows you to move the resulting tonal and noise samples to a new layer.

Keep Zone

Allows you to keep the original zone after decomposing.
