Using an aux in your DAW as an input for a reverb is a tried-and-true mixing technique. It helps you separate the verb from the source material and lets you dial in exactly how much reverb you want. Sometimes, however, you’ll find that the signal going through the reverb comes out sounding thin. If you’re looking for a “thicker” reverb sound, try compressing the reverb by adding a compressor plug-in on your auxiliary track after the reverb plug-in. This can help fatten up the reverberated signal for a nice, lush verb. You don’t want to add so much compression that you crush your reverb, but just enough to thicken it up. Experiment with various attack and release times to shape the reverb, as well as different compression ratios and thresholds. The result is different from choosing a different algorithm, preset, or reverb plug-in; give it a try!
