Every mixing engineer knows that moment: Your individual tracks sound great, but the moment they hit the mix bus, something’s off. The low end is muddy. The mids are harsh. Nothing glues together.
You reach for your EQ, start hunting for problems. Then you add a bus compressor, but it takes forever to find the right threshold, ratio, and makeup gain that works across different sections of your song.
30 minutes later, you’re still tweaking, second-guessing every move, and your mix still doesn’t have that professional cohesion you’re chasing.
What if your bus processor could think for itself?
The ZeroBus Approach
We combined two essential processes that every professional mix needs, spectral balance and bus compression, into a single, intelligent plugin that analyzes your audio and adapts automatically.
STEP 1: AUTOEQ
Continuous automatic equalization across 31 bands that balances your spectrum in real-time. No frequency hunting. No endless sweeping. Just instant tonal correction.
- 31-band continuous analysis
- Real-time spectral balancing
- Transparent, musical correction
- 0-200% control range
STEP 2: SMART COMPRESSION
Two compression modes that learn your material and automatically adapt threshold, makeup, and processing to deliver perfect bus glue or parallel punch.
- FAT Mode: Parallel 1176-style compression for New York punch
- GLUE Mode: Serial SSL-style compression for mix cohesion
- Automatic threshold learning
- Adaptive makeup gain
How it works
INSERT ZEROBUS
Load ZeroBus on your stereo mix bus, drum bus, or any stereo subgroup.
HIT PLAY
Start playback. The AutoEQ works immediately. The compressor learns your material’s dynamics in seconds.
CHOOSE YOUR SOUND
Select FAT for parallel punch or GLUE for cohesive binding. Set your desired amount.
FINE-TUNE
Adjust EQUALIZATION (0-200%) and COMPRESSION (0-100%) to taste. Watch the reduction meter for visual feedback.
Features that make the difference
31-BAND AUTO EQ
Continuous spectral analysis and correction that keeps your frequency balance in check without manual intervention.
INTELLIGENT LEARNING
The compressor analyzes your material’s RMS and peak levels to automatically set optimal threshold and makeup gain.
DUAL COMPRESSION MODES
FAT: Parallel 1176-style targeting ~19dB GR
GLUE: Serial SSL-style targeting ~9dB GR
VISUAL FEEDBACK
Real-time EQ curve display and segmented gain reduction meter (0 to -20dB) for precise monitoring.
AUTO OVERSAMPLING
Automatic 2× oversampling below 88.2kHz for pristine audio quality with minimal latency.
ADAPTIVE UI
Light/Dark/Auto themes that follow your system preferences. Clean, brutalist interface that stays out of your way.
WHERE TO USE ZEROBUS
MIX/MASTER BUS
Get instant cohesion across your entire mix. The AutoEQ tames problematic frequencies while the GLUE mode binds everything together with transparent compression.
Result: Professional polish in seconds. Your mix suddenly sounds “finished” with balanced spectrum and natural glue.
DRUM BUS
Remove boxiness and resonances with AutoEQ, then slam it with FAT mode for that New York-style parallel compression punch.
Result: Thick, punchy drums with preserved transients and enhanced body. The parallel approach keeps your original dynamics while adding massive thickness.
FAT VS GLUE: WHICH MODE?
| ASPECT | FAT MODE | GLUE MODE |
| Model | 1176-style parallel compression | SSL 4K-style serial compression |
| Processing | Compressed signal blended with dry (New York style) | Serial compression on entire signal |
| Target GR | ~19dB on compressed path during learn | ~9dB peak reduction |
| Character | Aggressive, punchy, thick | Smooth, cohesive, transparent |
| Best For | Drums, parallel density, presence | Mix bus, vocals, natural glue |
| Transients | Preserved from dry signal | Controlled but natural |
| Control Range | 0-100% (50% = 50% dry/wet blend) | 0-100% (50% ≈ 3-4dB GR) |
Quick Guide: Use GLUE when you want transparency and cohesion. Use FAT when you want thickness and impact. Both modes learn your material automatically—no threshold hunting required.
