Background noise can reduce the clarity and impact of audio projects in Adobe Audition. This guide provides practical steps, tools, and best practices for effectively reducing noise while preserving the desired sound. Whether you’re editing interviews, podcasts, or music tracks, a structured approach helps achieve clean, professional results.
The following sections outline a practical workflow, from quick fixes to in-depth processing, so you can tackle noise in a way that fits your project and studio setup.
Quick Answer
Use a combination of automated noise reduction and precise spectral editing: start with a targeted noise print, apply moderate noise reduction, and fine-tune with spectral noise reduction or a dedicated noise reduction plugin. Always preview with dialogue or music to avoid artifacts.
What You’ll Need
- Adobe Audition with access to built-in noise reduction tools
- Adobe Audition noise reduction plugin
- VST noise reduction plugin for DAW
- iZotope RX noise reduction plugin
- Spectral noise reduction plugin for audio
- Noise gate plugin for DAW

Before You Start
Plan a quiet editing session and work on a clean project file. Identify the noisiest passages using a short sample, and isolate a noise print for accurate removal. Safety note: avoid heavy processing on low-quality recordings, which can introduce artifacts. Allow sufficient headroom for dynamics, and consider the overall loudness of the project to prevent clipping during processing.
Time estimates vary by project: simple noise reduction can take a few minutes per clip, while complex dialogue or multi-track sessions may require longer review and tweaking.
Step-By-Step: How To Get Rid Of Background Noise In Audition
- Select the noise-only portion of your track to capture a noise print.
- Open the Noise Reduction/Restoration effects panel and apply the noise print to the overall clip.
- Choose a moderate reduction amount to preserve natural voice or instrument tone.
- Experiment with a spectral noise reduction option to target specific frequencies without dulling the entire signal.
- If the track has long, steady noise, try a Noise Gate plugin to suppress low-level background noise during silence.
- Use a side-chain or keying method to preserve transient details during noise reduction if supported by your plugin.
- A/B compare the processed and unprocessed sections to ensure the natural sound remains intact.
- Apply gentle post-processing like light compression or EQ to reintroduce clarity after noise reduction.
- Consider splitting the workflow: clean up dialogue first, then address ambience in the mix stage.
- Render a test export and listen on different devices to confirm the noise reduction holds across playback environments.
- Document settings used for future projects to ensure consistency and faster processing next time.
- Save a version with non-destructive edits to revert if artifacts become noticeable later.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Metallic or hollow artifacts after processing | Overaggressive noise reduction | Reduce reduction amount and adjust spectral modes | Test on short samples before full clips |
| Voices sound muffled | Low-frequency attenuation or over-filtering | Restore high-pass filter settings or adjust EQ | Use gentle, incremental adjustments |
| Residual hiss during pauses | Noise print not representative or constant noise | Capture a better noise print; apply noise reduction selectively | Split processing for noise-only regions |
| Clicking or pumping artifacts | Dynamic changes introduced by processing | Increase attack/release times on noise gate; reduce aggressive reduction | Fine-tune parameters with small increments |
Common Mistakes
- Applying heavy noise reduction across entire tracks instead of targeted sections.
- Rushing the capture of the noise print; inaccurate prints lead to poor results.
- Ignoring frequency balance, resulting in muffled voices or artifacts in the high end.
- Relying on a single tool; combining spectral reduction with gate or EQ often yields better results.
Take time to audition processed sections at multiple listening levels to catch artifacts early in the workflow.
Tips For Best Results
- Work with a high-quality capture of the noise profile that matches the quiet parts of the track.
- Use non-destructive editing whenever possible to keep original audio intact.
- Combine noise reduction with subtle EQ to restore natural brightness after processing.
- Apply noise reduction in small, iterative steps rather than a single heavy pass.
- Document your settings and save custom presets for repeat projects.
Call A Professional
Consult a specialist if the recording involves complex acoustic issues, such as heavy room reverberation or overlapping sound sources. Signs to seek professional help include persistent artifacts after multiple processing attempts, inconsistent results across clips, or non-speech audio elements that require more advanced restoration techniques.
FAQ
What is the best starting point for noise reduction in Audition?
Capture a clean noise print, apply a light noise reduction, and refine with spectral reduction for targeted frequencies.
Can I use third-party plugins with Audition for noise reduction?
Yes, several VST noise reduction plugins integrate with Audition to expand the available options.
Should I apply noise reduction before or after leveling audio?
Apply noise reduction before leveling to prevent noise from riding the same level as the signal.
What settings are recommended for listening on headphones?
Use moderate noise reduction and avoid aggressive filtering that can cause listener fatigue on small speakers or headphones.
Buying Guide
Choosing the right noise reduction workflow involves several factors. Consider the size of the project, noise characteristics, and the intended playback environment. Why does size matter? Larger projects with multiple tracks benefit from robust, high-quality plugins that can handle complex spectral noise patterns. Noise reduction quality often correlates with the precision of spectral editing tools and the accuracy of noise prints.
Key buying factors include:
- Noise reduction quality: Look for spectral editing capabilities and control over target frequencies.
- Filter transparency: Favor plugins that minimize artifacts and preserve natural tone.
- Compatibility: Ensure the plugin supports your DAW and system (Windows/macOS) and provides stable VST/AU formats.
- Ease of use: A clear UI and sensible presets help speed up workflows, especially for quick-turnaround projects.
- CPU efficiency: Some spectral tools are CPU-heavy; consider your computer’s performance for large projects.
- Reliability and updates: Regular updates and solid customer support improve long-term value.
- Placement and room considerations: If noise comes from room acoustics, address mic placement and isolation in addition to plugins.
When evaluating options, compare built-in Audition tools against third-party plugins like iZotope RX and spectral noise reduction plugins. Testing with your typical project type—dialogue, voiceover, or music—helps determine the best fit.
