The nvelope plugin benefits from higher sample rates in two ways: In the first place, it can react to changes in the source signal faster, which is of great importance for the impulse shaping process.
Secondly, it reduces aliasing artifacts and therefore brings the high frequency filter curves of the nvelope even closer to its analog counterpart.
The nvelope plugin employs the oversampling technique in order to enjoy these advantages even if lower sample rates are used. This means that the basic sample rate of a project is multiplied by a certain factor inside the plugin without the need to set the complete project to a higher frequency.
This method consumes a certain amount of CPU power, but the acoustic result speaks for itself. The nvelope plugin uses oversampling according to the following rules:
• Project sample rate lower than 50 kHz: 4x oversampling
• Project sample rate lower than 100 kHz: 2x oversampling
• Project sample rate higher than 100 kHz: no oversampling
