Volume and Pan

Volume and Pan

NoteHound has separate volume controls for the audio track and the MIDI synth, plus stereo level meters and pan controls for each.

Volume and audio controls

Audio Channel Strip

  • Label: “AUDIO” in bold orange text.
  • Volume Slider (vertical) — range 0% to 100%, default 50%. Double-tap to reset to 50%.
  • Mute Button (speaker icon) — tap to mute/unmute the audio track. When muted, the icon changes to a crossed-out speaker and the button highlights.
  • Stereo Level Meter — two vertical bars (left/right channel) with 24 segments each, covering -48 dB to 0 dB. Segments are green at normal levels, yellow/orange at hot levels, and red at clipping. Peak dB value shown above.
  • Pan Knob (circular) — drag vertically to adjust stereo pan. Range -1.0 (full left) to +1.0 (full right). Down = left, up = right. Center shows “C”, left shows “L50”, right shows “R75”, etc. Double-tap to reset to center.

MIDI Channel Strip

  • Label: “MIDI” in bold cyan text.
  • Same controls as the Audio strip: volume slider (0—100%), mute button (music note icon when unmuted, minus circle icon when muted), stereo level meter, and pan knob. The MIDI channel controls the built-in synth that plays piano roll notes.
  • Default state: muted.

How to Mute/Unmute Audio or MIDI

Tap the round mute button below the volume slider. The button toggles between unmuted (dark, subtle) and muted (highlighted with accent border, white icon). This is independent of the system volume.

Double-Tap Reset

Double-tap any slider or knob to reset it to its default value — 1.0x for speed, 50% for volume, center for pan.

Audio Offset

If your audio file starts slightly early or late relative to the MIDI, use the Audio Offset control to shift the audio forward or backward in time. Toggle offset mode from the waveform toolbar (left/right arrows icon) — when active, dragging the waveform adjusts the MIDI-to-audio offset instead of scrubbing.

Tip: If you’re playing along with a recording and the pitch doesn’t match your instrument, check that Speed Control is set to 1.0x. Speed changes do not affect pitch, but make sure no accidental adjustment has been made.
