Multi-Source Binaural-ish Shifter + Flash

Safety note: Flashing visuals can trigger seizures in people with photosensitive epilepsy. Keep frequencies low, keep STOP available, and don’t use this if you’re at risk.

Preset title

Description / notes

1) Global shift table

CSV lines: timeSeconds, shiftHz

Shift end mode

Max |shift| clamp (Hz)

0–20 Hz.

Any source with Shift = On follows this table.

2) Global volume envelope

CSV lines: timeSeconds, volumePercent

Envelope end mode

Max envelope clamp (%)

0–100%.

Any source with Envelope = On multiplies its gain by this table.

3) Audio sources

Each source can be:

Sine — cleanest for true binaural
File — local audio upload
URL — static audio URL

Shift smoothing (ms)

FIR Hilbert taps (shifted file/URL mode)

Master headroom

Visual max frame dt (ms)

4) Flash colors + timing

Comma-separated hex colors (#RRGGBB)

Notes:

Source weights are normalized automatically so the total mix stays bounded.
A gentle master compressor is added as a safety net.
Wet Mix is per-source and only applies to shifted file/url sources.
Local files themselves are not saved in presets, only their slot/type/settings.
