About Signal Probe
BandLab Membership
Signal Probe is exclusive to active BandLab Membership subscribers.
Signal Probe lets you monitor and analyze the audio signal at different points in a track or bus signal chain. It provides real-time visual feedback, making it easier to troubleshoot routing, inspect plugin processing, and verify signal levels throughout your project.
You can access Signal Probe from each plugin in a track or bus FX chain, as well as at the end of the signal chain for tracks and buses.
Features
Signal Probe includes multiple analysis tools to help you visualize and monitor your audio signal.
Spectrum Analyzer
Displays the frequency spectrum of the incoming audio in real time, making it easy to identify the balance of low, mid, and high frequencies.
Use the Spectrum Analyzer to:
- Inspect the frequency content of a signal.
- Identify unwanted resonances or excessive frequencies.
- Compare how EQs and other processing affect the signal.
Phase Scope
Displays the stereo phase relationship between the left and right channels.
Use the Phase Scope to:
- Check stereo imaging.
- Detect potential phase cancellation.
- Monitor mono compatibility.
Level Meter
Provides real-time level monitoring for the audio signal.
Use the Level Meter to:
- Monitor signal peaks.
- Check overall signal levels.
- Prevent clipping.
- Verify gain staging throughout the signal chain.
CPU Load Meter
The CPU Load Meter displays the processing load associated with the monitored signal, helping you identify plugins or processing chains that place a heavier demand on your system.
Probe Modes
Signal Probe lets you inspect the signal at different stages of the processing chain.
- Pre
-
Displays the incoming signal before it is processed by the selected plugin.
Use this mode to verify the original signal entering the plugin.
- Pre/Post
-
Displays both the input and output signals simultaneously, allowing you to compare how the plugin affects the audio.
This mode is useful for evaluating changes made by EQs, compressors, saturators, and other processing effects.
- Post
-
Displays the signal after it has been processed by the selected plugin.
Use this mode to verify the final output produced by the plugin.
Where to Access Signal Probe
Signal Probe can be opened from several locations throughout Cakewalk Sonar.
Plugin Insert
You can open Signal Probe from any plugin in a track or bus FX chain.
To locate Signal Probe for a plugin:
- Open the plugin window.
- Navigate to the Plugin Menu Bar.
- Click Signal Probe icon.
Opening Signal Probe from a plugin lets you monitor the audio signal at that specific stage of the processing chain, making it easy to compare the signal before and after individual effects.
End of a Track Signal Chain
You can also access Signal Probe at the end of a track's signal chain in the Console View.
To locate Signal Probe for a track:
- Open the Console View.
- Locate the desired track.
- Click the Signal Probe icon above the track's level meter.
This lets you monitor the final processed output of the track after all inserts and processing have been applied.
End of a Bus Signal Chain
Signal Probe is also available for each bus in the Console View.
To locate Signal Probe for a bus:
- Open the Console View.
- Locate the desired bus.
- Click the Signal Probe icon above the bus level meter.
This lets you monitor the final processed output of the bus after all inserts and processing have been applied.
Troubleshooting Audio
Signal Probe can help identify where audio issues occur within a signal chain. For example, you can:
- Verify that audio reaches a plugin.
- Compare the signal before and after processing.
- Determine where audio stops in the signal chain.
- Confirm that plugins are processing audio correctly.
- Monitor signal levels to prevent clipping.
- Check stereo phase relationships.
- Analyze frequency content before and after processing.
By probing different locations in the signal chain, you can quickly isolate routing or processing issues without modifying your project.
Tips
- Use Pre/Post mode to compare the effect of plugin processing.
- Monitor the Spectrum Analyzer when adjusting EQ or tonal balance.
- Use the Phase Scope to check stereo width and mono compatibility.
- Keep an eye on the Level Meter to maintain proper gain staging.
- Watch the CPU Load Meter when troubleshooting performance or evaluating processor-intensive plugins.
