Adobe Audition provides a robust set of AI-powered tools to reduce or eliminate background noise in audio recordings with Adobe AI audio noise Reduction feature. These intelligent solutions can help clean up difficult audio environments ranging from outdoor locations to noisy indoor settings. In this guide, we’ll explore the most effective techniques for harnessing Adobe’s noise reduction capabilities.
Overview of AI-Driven Noise Reduction
Audition leverages Adobe Sensei artificial intelligence to analyze audio signals and build noise profiles. It can then subtract out consistent broadband noise as well as ambient background sounds. The key benefits of these AI tools include:
- Requires less manual tuning compared to traditional noise reduction
- Can isolate and remove very specific noise frequencies
- Continually adapts to the noise signature throughout a recording
- Less prone to damaging the source audio signal
- Preserves more natural tone compared to standard noise filters
When combined creatively, Audition’s noise reduction effects can rescue even very problematic audio.
DeNoise – General Broadband Noise Removal
The DeNoise effect is designed to remove consistent background noise like HVAC rumble, traffic, airplane noise and more. It builds a smart noise profile through AI analysis.
To use it:
- Select your clip and go to Effects > Noise Reduction/Restoration > DeNoise
- Adjust the Noise Reduction slider subtly (try 10-20 first)
- Listen carefully as you increase the reduction amount
Start with a light touch, as too much reduction can damage the actual audio. DeNoise works well for attenuating general room tone and hum.
Dialogue Isolate – Focusing Speech & Reducing Noise
Dialogue Isolate uses AI to isolate speech from background noise. It works best with recordings of just one speaker at a time.
To use Dialogue Isolate:
- Go to Effects > Special > Dialogue Isolate
- Enable it on your clip and adjust settings like Noise Reduction, Suppression
- This works well for interviews and single-speaker recordings
The AI analyzes and models the voice, allowing it to selectively reduce noise while keeping speech intact.
Capture Noise Print – Sample the Noise Itself
You can sample just the isolated background noise you want to eliminate:
- Select a region in your audio with just the target noise
- Go to Effects > Noise Reduction/Restoration > Capture Noise Print
- This builds a noise profile that can be subtracted out
Use this when you have a clean section of just the hum or noise itself you want to remove from the rest of the clip.
Adaptive Noise Reduction – Consistent Noise Removal
Adaptive Noise Reduction works well for consistent noise like steady hum or traffic rumble:
- Go to Effects > Noise Reduction/Restoration > Adaptive Noise Reduction
- Adjust settings like Noise Floor, Reduction Amount, Frequency Bands
- Listen closely as you tweak the settings
This uses an adaptive algorithm that continually adjusts itself based on the noise signature. It removes the noises while preserving more of the source audio.
Parametric EQ – Notch Filtering
Use Parametric EQ to isolate and notch out narrow noise bands:
- Add multiple EQ points and tighten the Q/Bandwidth
- Slowly increase the Gain reduction to filter out the target noise frequency
- Combine this technique carefully with broader noise reduction
The parametric EQ allows you to surgically target exact noise frequencies. This works well for periodic hum and whine.
When using Adobe’s noise reduction tools, follow these guidelines:
- Apply subtle settings at first, increasing slowly
- Listen closely when adjusting parameters
- Try combining several noise reduction effects
- Use EQ notch filtering for periodic noises
- Capture a pure noise print sample if possible
- Consider post-processing with compression/limiting
The key is to take an iterative approach combining both broad and surgical techniques. When applied with a gentle touch, Adobe’s AI-powered noise reduction can rescue even very challenging audio.
Sample Noise Reduction Workflow
Here is an example workflow for cleaning up a recorder interview with background HVAC rumble:
- Apply DeNoise broadly to attenuate the rumble
- Use Dialogue Isolate to focus the speech and further reduce noise
- Capture a noise print from a brief section of just the rumble
- Apply Adaptive Noise Reduction tuned to the noise print
- Insert parametric EQ points to notch out periodic hum frequencies
- Compress/limit the final audio gently to smooth out variations
This combines the AI-powered noise reduction with frequency-targeted EQ filtering and light compression. When harnessing Audition’s intelligent tools, even difficult audio can be transformed into a clean, usable recording.
Adobe Audition provides some of the most advanced AI audio noise reduction capabilities available today. The combination of adaptive noise profiles, dialogue isolation, parametric EQ, and AI-assisted effects gives users an extremely powerful toolbox for audio noise removal and rescue. While these tools require an iterative, subtle touch, they can extract surprisingly clean speech from even very noisy environments. For anyone recording interviews, music, or audio in unpredictable locations, Audition’s audio noise reduction tools are an indispensable asset.
