Soundwave — Frequency Memory is a skill-based audio game developed by Mantle Software. Players listen to a tone, then recreate it from memory using a frequency slider. The closer the match, the higher the score. Compete on global leaderboards in Ranked Play, take on the Daily Challenge shared by every player worldwide, test your ear in Chord Mode by identifying root notes and chord qualities, or go head-to-head against another player in real-time Versus Mode. Progress is tracked through an SR rating system with tiers from Bronze to Legend.
