A frequency is boosted or cut. Listen and pick the right frequency from 9 choices — multiple choice frequency recognition.

A hidden EQ curve is applied to audio. Drag your bands to match it by ear — frequency, gain, and Q across 6 filter types.

Two EQ curves are shown — one is applied to the audio. Identify which curve matches the target by ear.

A target compressor is applied to audio. Dial in threshold, ratio, attack, release, and knee to match it by ear.

A reference signal plays, then a level-adjusted version. Identify whether the gain was boosted or cut, and by how much.

Two signals play side by side — one compressed, one dry. Identify the compressed audio.

A hidden distortion is applied to audio. Match the drive, type (soft clip, hard clip, tape), mix, and tone by ear.

Two modes in one: identify a sound's stereo pan position, or guess the stereo width between two panned sources.

A bandpass-filtered sound plays at a hidden stereo position. Click the 2D grid to identify both the frequency and pan.

A hidden reverb is applied to audio. Match the room size, decay, pre-delay, damping, and wet/dry by ear.

Match a target delay by ear. Set delay time, feedback, and wet/dry to replicate the processed signal.

A hidden signal chain processes the audio. Listen and arrange the effects — EQ, compression, reverb, saturation — in the correct order.
