LRC7 for iPhone

Quick Summary of LRC7

LRC7 is a seven-band equalizer provided by Neon Silicon LLC for iOS and macOS. Packaged as an Audio Unit (AU), the app functions as both the plugin container and its user manual. To use LRC7 you must load it inside an AU-compatible host or a digital audio workstation (DAW).

Main Capabilities

• A selection of Butterworth low‑pass and high‑pass filters for smooth frequency roll-off
• Notch filters for surgically removing problem frequencies
• Fully parametric peak/cut bands for precise tonal shaping
• High-shelf and low-shelf shelving filters for broad tonal adjustments
• Each of the seven bands can be turned off independently so the signal can pass untouched

Technical Details

• Frequency coverage spans from 10 Hz up to 20 kHz, giving full-range control
• Filter ordering is flexible — bands may be arranged in any sequence to suit the workflow
• The resonance/Q control is continuously adjustable from 0.0 to 1.0; exact response depends on the selected filter type
