Orinj version 7.0.0
The Orinj DC Removal is an effect that removes any shift in the signal away from its middle values. If a signal wave, for example, oscillates between positive and negative values, the DC Removal effect makes sure that the signal wave is centered around the middle (around zero). If the signal wave tends to have more or larger positive values than negative values, the DC Removal will push the wave towards the negative values to ensure that, on average, the positive and negative values are approximately equal.
The shift in the signal is its direct current (DC). Simplistically, it is the part of the signal that does not oscillate. By shifting the signal wave towards the middle, this part is removed.
Using the Orinj DC Removal
The Orinj DC Removal can be added to tracks, auxiliary channels, and the master channel in the multitrack session view and to waves in the single wave view.
- To add the effect to a track in the session, first click on the track to select it. Click on Effect, Other, and then on Orinj DC Removal in the menu.
- To add the effect to an auxiliary channel in the session, click on Track, then Groups / Aux Channels, and then on Aux Channel Controls in the menu. In the auxiliary channel control dialog, click on the Add button.
- To add the effect to the master channel in the session, click on Track and then on Master Channel in the menu. In the master channel dialog, click on the Add button.
- To add the effect to a wave in the single wave view, click on Effect, Other, and then on Orinj DC Removal in the menu.
You will see the following dialog.
When this dialog becomes visible, the Orinj DC Removal effect has been added. Adjust the parameters of the DC Removal and click Close.
Orinj DC Removal parameters
The Orinj DC Removal adjusts the values of the signal wave based on their averages and changes the amount of adjustment slowly. This is necessary to avoid distortion. This is reflected in the parameters of the effect.
See Orinj Effects for an explanation of the Title, Track, Presets, and Bypass controls. The remaining Orinj DC Removal controls are described below:
- Attack: Use these controls – the box and the slider – to set the attack of the DC Removal. The attack is the amount of time it takes for the DC Removal adjustment to change from zero to 1 dB. The attack is specified in milliseconds (ms) and can be between 0 ms and 200 ms.
- Average: Use these controls – the box and the slider – to set the amount of time, over which the DC Removal will compute the average of positive and negative signal values and measure the shift of the signal from the middle. The average is also measured in milliseconds and can be between 0 ms and 100 ms.
See Orinj Effects for additional notes on: where Orinj effects can be used, using boxes and sliders that impact the same parameter (such as the box and slider for the attack), applying effects to mono and stereo waves, and using effects during playback. See Orinj Working with effects for additional information on creating, modifying, moving and removing effects.
