The settings page is split into four sections: Practice, Sound, Microphone, and Advanced. The first three sections keep the beginner controls visible. The advanced section stays collapsed until you open it.

The visible settings cover the controls most users need day to day:
Exercise speed sets the tempo in beats per minute.
Number of rhythm patterns controls the size of rhythm practice sets.
Number of exercises sets the length of a test run.
Volume adjusts playback loudness.
Instrument selects the melodic sound used for ear training.
Voice class selects the target singing range.
The microphone section also includes short helper descriptions for the tolerance and calibration controls. Those descriptions explain when to tighten the tolerance and when to recalibrate silence.

Advanced settings expose detection algorithms and thresholds for difficult microphones or noisy rooms. Use them when the default detection behavior is not enough. The section is collapsed by default and includes a button so you can restore the factory values after experimenting.
The advanced section includes separate groups for clapping detection and singing detection. Typical controls include onset method, onset threshold, input gate, minimum onset strength, silence level, pitch method, scoring mode, pitch confidence, and stable pitch frames.
