Ring Out is built for ringing out wedges and a PA before soundcheck. Arm LEARN, bring the gain up slowly, and let it notch the frequencies that start to ring; then disarm it and keep the notches for the show. Keep a mute within reach while you do it: a ring can grow faster than any detector can react.
Ring Out is open source under GPL-3.0-or-later. View the source, report issues, or contribute on GitHub.
Features
- LEARN: arm the detector for 60 seconds while you raise the gain, and it places a notch on each ring it hears
- CATCH: one press places or deepens one notch on the next ring, for the ring that turns up mid-show
- Up to twenty narrow notches in a bank of strips, each with on/off, its own CUT fader, frequency, and Q
- A ring that comes back deepens or widens its existing notch instead of taking a new slot
- Tells a ring from a note by how it behaves: feedback holds or grows, a note decays, and harmonic-rich sounds are passed over
- Two sensitivity settings: Low for conservative detection, High for quieter rings and faster response
- Stereo detection that a ring in one channel or opposite-polarity signals cannot hide from
- Q SCALE and CUT TRIM across every notch
- LINK trades output level for cut depth, so turning up also deepens the notches
- Spectrum display with the notch curve: drag a notch's node for frequency and cut, wheel for Q
- A ripple on the graph marks each notch the detector places or deepens
- Input and output level meters with peak hold
- Notches fade in and out smoothly, with no clicks when filters change or on bypass
- User presets that store the filter table with the settings
- Typed value entry for each notch's cut, frequency, and Q
- Host automation of Sensitivity, Learn, Catch, Clear, Q Scale, Cut Trim, Link, and Output
