1. Open the reference file and the target file to which you want to apply the reference.
2. Insert Repli-Q as a plug-in.
3. Start playback for the reference file, then click on Learn Spectrum. Click Learn Spectrum again to turn off the “learning” process, then stop playback.
4. Click on Save Spectrum. Once saved, this spectrum can also be used for future spectral matching, and loaded from the “Load” field.
5. Start playback for the target file, then click on Learn Spectrum. The reference file response is the yellow line, and the target file response is the green line.
6. Click Learn Spectrum again to turn off the “learning” process. A blue line appears that shows the target file’s new spectral response. This response depends on the setting of the Matching slider (see next).
7. Adjust the Matching slider for the desired spectral response. At 0, the target response is unchanged. At 100, the target response matches the reference response. Often, you’ll want a setting between these two extremes, where the reference “influences” the target rather than “takes it over.” Once you’ve nailed the sound you want, perform a bounce or apply the Repli-Q effect.
-In Steps 3, 5, and 6, it’s a good idea to loop short samples. If the program “learns” while there’s silence (e.g., if you hit Learn before initiating play), the silence will be averaged in and give a false reference.
-The Smoothing fader evens out the response a bit in case the target sounds too “peaky” or has unwanted resonances.
