Gap Killer
Automatic silence trimming at track boundaries.
TIP
For loudness normalization, see EBU R128.
Path: Station → Settings → Audio Processing
How It Works
Gap Killer removes silence at the beginning and end of audio files. This creates tighter transitions between tracks.
The system analyzes the audio waveform and trims sections below the configured threshold:
- Start Threshold: Silence level at the beginning of tracks
- End Threshold: Silence level at the end of tracks
Audio below the threshold is considered silence and removed.
Configuration
| Setting | Range | Default | Description |
|---|---|---|---|
| Start Threshold | -44 to 0 dB | -40 dB | Audio below this level is trimmed from the start |
| End Threshold | -44 to 0 dB | -40 dB | Audio below this level is trimmed from the end |
Recommended Values
| Use Case | Start | End |
|---|---|---|
| Music radio | -40 dB | -40 dB |
| Speech/Podcast | -35 dB | -35 dB |
| Preserve dynamics | -44 dB | -44 dB |
TIP
Lower values (closer to -44 dB) preserve more audio. Higher values (closer to 0 dB) trim more aggressively.
