The Sauce Mixer

The Sauce is Boumb'App's central audio mixing console. It handles channel balancing, stereo field placement, dynamic control, and spatial effects processing.

1. Channel Strips

Every active voice in the project (JuicyBox drum lanes, SynthLab instances, and the Master bus) feeds into a dedicated channel strip:

  • Level Fader: Linear gain regulator calibrated in decibels (dB). Double-clicking snaps the fader back to unity gain (0 dB).
  • Peak Meter: Real-time signal level monitoring with clipping indicator when exceeding 0 dBFS.
  • Stereo Pan: Positions the track's audio output between Left (L) and Right (R) channels.
  • Mute (M): Immediately cuts signal transmission from the channel strip.
  • Solo (S): Isolates the selected track by cutting all non-solo channels.

2. FX Chain & Audio Processing

Select a channel strip to open its dedicated effects rack. If no track is selected, the inspector prompts: PICK A TRACK TO SPRINKLE SOME SPICES.

Click + Add Spice to insert audio processors into the signal path.

Available Audio Effects

  1. Reverb:

- Recreates natural acoustic reflections of rooms and halls. - Parameters: Decay (tail duration), Pre-Delay (reflection onset time), and Wet/Dry (processed to direct signal ratio).

  1. Ping-Pong Delay:

- Stereo echo repetitions alternating across left and right speaker channels. - Parameters: Delay Time (tempo-synced note division) and Feedback (echo repetition count).

  1. Analog Distortion:

- Warm tube-style harmonic saturation adding bite, presence, or aggressive drive. - Parameters: Drive (saturation intensity) and Tone (high-frequency character).

  1. Parametric Equalizer (EQ):

- Multi-band frequency filtering (Low Shelf, Mid Peak, High Shelf) to carve out space and eliminate frequency masking between bass and kick drums.

3. Master Bus & Digital Protection

The Master channel sums all mixed audio paths:

  • Maintain peak levels below 0 dB to preserve dynamic headroom and avoid distortion.
  • An integrated soft-limiter prevents digital clipping on physical outputs and during WAV export.
