+      Fine-tune your instruments with Chromatic. Chromatic
+      detects the frequency of audio input, converts it to
+      a musical note with the correct semitone and octave,
+      and displays the cents error. Cents are displayed on
+      an analog gauge to make tuning more visually intuitive.
+      Requires PulseAudio or PipeWire.
