So you want to tune your Echoes in Wuthering Waves—good choice. In addition to boosting your abilities on the battlefield, you’ll need to tune your Echoes using the Echoes Interface to complete one of the missions in the Silver-haired Echo Trainer III side questline.
How to Tune the Echo in the Echoes Interface in Wuthering Waves
Defeating Tacet Discords can sometimes leave behind an Echo—a frequency—that the Rover can absorb for Data Bank EXP in Wuthering Waves. When you receive one, you can equip it to a character through the Resonator building menu. While some Echoes are great in their base form, you can “tune” them to increase their benefits.
Since you're here, chances are you're wondering how to complete the side quest or how to tune Echoes in general. Don't worry, because we're here to help.
To complete the quest or tune Echoes in Wuthering Waves, open the Terminal and go to the Resonator menu. From here, select the Echoes tab (the interface) and tap on one of the devices to open the list of Echoes.
