Official effect

DJ Brake

Currently the same synthetic lowpassed brake phrase as Tape Stop / Vinyl Stop rather than a differentiated DJ-style brake.

The current brake family does not slow down captured audio. Instead, it mixes in a separately synthesized lower phrase, low-passes that synthetic layer under `tone`, and offsets the right side by a short delay. `shape` raises the level of that brake-like layer, `mix` blends it with the dry phrase, and the declared `motion` control is inactive.

How It Works

Technical view

The current brake family does not slow down captured audio. Instead, it mixes in a separately synthesized lower phrase, low-passes that synthetic layer under `tone`, and offsets the right side by a short delay. `shape` raises the level of that brake-like layer, `mix` blends it with the dry phrase, and the declared `motion` control is inactive.

Signal Path

Compiled preview chain

Preview source: An internally generated picked-string phrase is widened to stereo as the dry source, and the current effect also layers a separately synthesized held or slowed phrase rather than capturing the live input into a loop buffer.

Preview source

An internally generated picked-string phrase is widened to stereo as the dry source, and the current effect also layers a separately synthesized held or slowed phrase rather than capturing the live input into a loop buffer.

Effect core

Dry phrase plus a separately synthesized lowpassed brake layer with a short right-side offset.

Signal path

The static waveform and the live player both reflect this compiled signal chain.

  • internal picked-string demo phrase
  • stereo spread with a short right-channel delay
  • separately synthesized brake phrase
  • low-pass shaping on the synthetic brake layer
  • short right-side offset on the brake layer
  • dry / brake blend
  • DC blocker
  • output gain trim
  • final tanh limiter

Controls that matter

These are the currently active controls detected in the FAUST source for this effect.

  • mix: Blends between the dry preview phrase and the synthesized brake phrase.
  • output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
  • motion: Declared in the shared control set but unused in the current preview code.
  • shape: Raises the gain of the synthesized brake phrase before it is mixed with the dry source.
  • tone: Sets the low-pass cutoff on the synthesized brake phrase.

Code-backed analysis

The generated description is tied to the active helper blocks and routing found in the current DSP.

Controls

Audible controls in this DSP

  • mix

    Active

    Blends between the dry preview phrase and the synthesized brake phrase.

    Higher settings bring the slowed synthetic layer forward over the dry source.

  • output_gain_db

    Active

    Applies final post-effect level trim after DC blocking and before the output limiter.

    Matches loudness without changing the actual loop, freeze, or glitch structure.

  • motion

    Active

    Declared in the shared control set but unused in the current preview code.

    Changing it currently has no effect on the sound.

  • shape

    Active

    Raises the gain of the synthesized brake phrase before it is mixed with the dry source.

    Makes the stop-like layer more dominant.

  • tone

    Active

    Sets the low-pass cutoff on the synthesized brake phrase.

    Makes the slowed layer darker at low settings and more open at high settings.

Analysis

Code-derived notes

Current implementation shares the same synthetic brake-layer architecture across Tape Stop / Vinyl Stop and DJ Brake, and the declared motion control is inactive. DJ Brake is currently identical to Tape Stop / Vinyl Stop.
