Traverse

Traverse is a lo-fi cassette effect and delay plugin by Audio Damage for macOS, Windows, Linux, and iOS. It combines a cassette simulation model (drive, wow, flutter, tilt-EQ tone) with a stereo tape style delay, so every echo repeat passes back through the full cassette chain and degrades, blooms, and saturates with each pass. Traverse adds a tape loop splice point emulator with four interacting controls and a curated noise generator with nine voices, including hiss, crackle, fan rumble, 50/60Hz hum, and Card Reader. Available as VST3, AU, AAX, and CLAP for desktop, and AUv3 for iPhone and iPad. No DRM, no subscription, and a perpetual license. Traverse is the third entry in Audio Damage's Motion Effects family alongside Ascent and Descent.

Tips

Use Traverse on a drum bus to age your beat into something that sounds like a fourth-generation cassette dub. Drop it on a vocal for warmth, hum, and a tape-echo wash that sits behind the dry signal rather than fighting it. Send a clean synth pad into it and pull up the splice rate and the Card Reader noise voice for a broken-equipment feel. Park it across a guitar take, push Drive, and the feedback path turns a single chord into a slow self-saturating drone. One plugin, one signal flow, no chaining, infinite possibilities.

Features:

• Cassette engine with magnetic-hysteresis tape model - State-dependent nonlinearity hysteresis equations wrapped between pre-emphasis and de-emphasis filters, with oversampling at the saturator stage. Internal gain compensation keeps output level consistent across the full Drive sweep.
• Drive - Sets the cassette saturation amount from clean new tape to fully compressed and harmonically rich, with the hysteresis curve responding to signal history the way real tape does.
• Wow and Flutter - Two independent depth knobs for the cassette's slow pitch drift (Wow) and faster modulation jitter (Flutter), each driven by its own LFO with a noise component layered in. Per-channel modulation gives the stereo image a natural cassette wobble.
• Tone - Bipolar tilt EQ sitting inside the cassette signal flow. Darker to the left, brighter to the right, flat at center. One knob does the work of separate high and low shelves.
• Tape emulator inside the feedback loop - Every repeat is re-processed through Drive, Tone, Wow, and Flutter. Push Feedback and the repeats bloom into a self-saturating wash; pull it back for two or three colored echoes.
• Time - Stereo delay time from 20 ms to 10 seconds in free mode, or snapped to host-tempo beat divisions (straight and triplet, 1/32 through two whole notes) when Sync is engaged.
• Feedback - Recirculation amount, ceiling-limited so the loop cannot run away even with Drive at maximum.
• Width - Continuous ping-pong control. Positive values send the first echo to the right and cross-feed the channels.
• Splice system - Procedural tape splice simulator with four interacting controls. Time sets event rate (0.5 seconds to one minute between events, knob travel packed at the fast end where it matters). Depth sets the amount. Pitch and Amp toggle the pitch-chirp and amplitude-dip components of each dropout, so you can dial in anything from a clean spool to a worn-out shoebox tape.
• Curated noise generator - Nine procedural noise voices: Hiss, Crackle, Dust, Fan Rumble, 60Hz Hum, 50Hz Hum, White, Pink, and the Califone Card Reader. Pick a voice, set the amount, and the noise feeds straight into the cassette path where it gets shaped on every repeat just like the input signal does.
• Gated noise - When on, the noise floor drops 20 dB below the Noise setting whenever the input is silent, so the room tone speaks only when the track does and disappears between phrases.
• Post-delay routing toggle - Off (default) is the Space-Echo model: cassette first, delay second, with feedback returning through the full cassette chain. On flips the order so the cassette processes the delay tail only, turning Traverse into a more conventional tape-flavored delay with a clean input path.
• Mix - Standard dry / wet blend, defaulting to fully wet so the plugin reads as an effect from the moment it loads.
• Click-free Bypass - Smoothed 50 ms crossfade for live A/B comparisons and live performance use.
