Musical resonant filter bank
$9.99
Make noise, texture, and percussion sing. Add motion and stereo spread to basic sounds. Load samples and sculpt them endlessly. Leave your mark on any sound with harmonic filtering.
Sightlines is a playable harmonic filter. Built from a collection of resonant bandpass filters tuned to the harmonic series, designed to bring out a customizable set of musical frequencies in any sound. Tune it to a fixed frequency like a resonator, or send it MIDI to make it come alive as an instrument.
Sightlines can be loaded as an instrument or an audio effect. As an instrument, use it with samples, noise, or oscillators to construct sounds never heard before. As an effect, add movement and interest to any sound, and even impart tonality onto unpitched input.
SOUND SOURCES
• Noise – filter variable color noise and random noise bursts for Sightlines’ simplest and quickest output.
• Samples – send samples through resonant filters as one-shots or infinite looping versions of themselves, great for found sound and tonal samples alike.
• Synth – skip the filters entirely and use Sightlines as a harmonic synth, where you can customize and modulate the proportion of each harmonic in the signal.
• Audio effect – use Sightlines as an audio effect on any track.
MOVEMENT AND EFFECTS
• Manipulate overtones – stretch, bend, and reimagine the harmonic series to retune Sightlines’ output into realistic or indescribable sonic spaces.
• Quantize frequencies – snap all of Sightlines’ filters to a scale, to impart that key quality onto any sound.
• Balance bands – maneuver through the harmonic space by scanning, tilting, or spreading Sightlines’ bands.
• End of chain – make your output shine with a built-in chorus, BBD-style delay, and reverb.
FEATURES
• Modulation – modify any control in Sightlines with multiple LFOs, sequencers, smooth random sources, and performance effects.
• Presets – full preset control over every parameter in Sightlines. Cross-platform preset format for sharing with friends.
• Waymaker – connect to Sightlines’ sibling application, Waymaker, for sequencing and additional control over the pitch of Sightlines’ output.
Also available for macOS and Windows in VST3 / AU / AAX formats from Aqeel Aadam Sound.
