The Compressor V2 operator is a dynamic range compressor for audio processing. It reduces the volume of loud sounds above a certain threshold, helping to control audio dynamics and prevent clipping.

Compression
These settings control the core compression behavior.
| Option | Description | Range | Default |
|---|---|---|---|
| Threshold (0dBFS) | The level at which compression begins. Signals above this threshold will be compressed. | -48 to 0 | -18 |
| Ratio (1:1 - 20:1) | The amount of compression applied. A ratio of 4:1 means that for every 4 dB the signal exceeds the threshold, only 1 dB will pass through. | 1 to 20 | 3.5 |
| Makeup gain (dB) | Boosts the output signal to compensate for the volume reduction caused by compression. | 0 to +24 | 0 |
| Attack time (ms) | How quickly the compressor responds when the signal exceeds the threshold. Lower values catch fast transients. | 0 to 200 | 8 |
| Release time (ms) | How quickly the compressor stops compressing after the signal falls below the threshold. | 0 to 500 | 150 |
| Knee width (1-8 dB) | Controls the transition between uncompressed and compressed signal. A wider knee creates a more gradual, natural-sounding compression. | 1 to 8 | 2.8 |
Advanced
Additional settings for fine-tuning the compressor behavior.
| Option | Description | Values | Default |
|---|---|---|---|
| Compressor mode | Determines how the compressor detects signal levels. | Peak, RMS (default) | RMS (default) |
| Look ahead (ms) | Allows the compressor to "see" incoming transients before they arrive, preventing overshoot on fast peaks. | 1 to 8 | 4 |
Compressor Mode Options
| Mode | Description |
|---|---|
| Peak | Responds to instantaneous peak levels. Best for catching fast transients and preventing clipping. |
| RMS (default) | Responds to average signal levels over time. Provides smoother, more musical compression suitable for vocals and music. |
Warnings
Read-only indicators that alert you to potential issues.
| Indicator | Description |
|---|---|
| Signal overload | Displays a warning when the output signal exceeds 0 dBFS. Auto-resets after 2 seconds. |
| Peak Overload (dB) | Shows the peak overload value in dB when signal overload occurs. Auto-resets after 2 seconds. |
Output
Read-only meters showing the current compression activity.
| Meter | Description |
|---|---|
| Gain reduction Left (dB) | Displays the amount of gain reduction being applied to the left channel. Smoothed over 300 ms. |
| Gain reduction Right (dB) | Displays the amount of gain reduction being applied to the right channel. Smoothed over 300 ms. |
Actions
| Action | Description |
|---|---|
| Reset | Resets all operator settings to their default values. |
