Amplitude SplitNJoin

Description:
SplitNJoin enables you to create a frequency response curve by merging 2 existing responses, transitioning from one response to the next at a particular frequency.

Options:
@Frequency: specifies the frequency at which the resulting response should transition from the left response to the right response. The field can be automatically populated by clicking the left mouse button at the appropriate point in the graph.
Gain Adjustment: select left or right to automatically adjust the magnitude (of the left or right) curve to ensure smooth transition at the selected frequency

Use:
Usually a given technique in Acourate is used to determine the frequency response across the entire frequency range. However, in some cases one method is better in a given frequency range and another method, or the same method with different settings, may be preferred in the rest of the range.. Amplitude SpilNJoin can be used to combine the frequency response measurements.
Example:
For the creation of correction filters out the impulse response has to be processed with one of the smoothing methods of Psychoacoustics. These both offer advantages, which can also be combined. In this example, a strong correction in the bass range is to take place:


The Sliding Octave analysis usually produces a stronger correction. Look for a point at which the two curves overlap, and the stronger correction can be used below this point, with the more subtle correction used above it. Click the desired intersection point with the left mouse button and select FD Functions> SplitNJoin.

The clicked frequency automatically becomes the point at which the two curves are combined into a third.
