View HistoryRemove Background Noise from Audio with an Online Audio Denoiser
Clean up recorded speech affected by fan noise, hum, hiss, light static, or room ambience. Upload one MP3, OGG, WAV, M4A, or AAC file up to 50MB and 30 minutes, preview the processed audio, and download a 192 kbps MP3. Loud music, overlapping speakers, clipping, and strong echo may remain. This tool processes uploaded audio files, not live microphones, calls, or videos.

What Is an Audio Denoiser?
An audio denoiser analyzes a recording and reduces unwanted background sound while trying to preserve the main audio signal. Echora is designed primarily for recorded speech and applies noise reduction automatically, without requiring detailed audio-editing knowledge.
- Reduce low-level fan noise, hum, hiss, light static, and room ambience
- Clean up podcasts, interviews, narration, lessons, meetings, and voice notes
- Process uploaded recordings in the browser without installing desktop software
- Preview the cleaned result before downloading a new 192 kbps MP3
Clean Up Speech Without Desktop Software
Reduce distracting background noise while keeping spoken content as clear and natural as possible. The tool is designed for voice recordings such as narration, interviews, podcasts, lessons, meetings, and voice notes.
You do not need to create a noise profile or configure technical audio filters. Upload your recording and submit it for automatic processing, making it easier to clean up audio without learning traditional noise-reduction software.
Upload MP3, OGG, WAV, M4A, or AAC audio. Each file can be up to 50MB and 30 minutes long. The processed result is provided as a 192 kbps MP3 that can be previewed and downloaded from the browser.
Echora runs in your browser, so there is no desktop application or plugin to install. New users can receive complimentary credits after signing up. Estimated credit usage is based on the length of the uploaded recording.
How to Remove Background Noise from Audio Online
Prepare a Clear Speech Recording
Choose the audio file you want to clean. For more consistent speech enhancement, use a recording with one main speaker, reasonably stable volume, and as little clipping as possible.
- •Use MP3, OGG, WAV, M4A, or AAC
- •Keep the file at or below 50MB
- •Keep the recording at or below 30 minutes
- •Trim unrelated silence when practical
- •Avoid files where music or another speaker is louder than the main voice
- •Use the original source when the recording is clipped or heavily distorted
Upload and Denoise the Audio
Upload the recording to the audio denoiser and start processing. The tool applies assisted noise reduction automatically, so there are no separate threshold, pitch, equalizer, or noise-profile settings to configure. The page displays the estimated credit cost based on audio duration before you submit, so longer recordings require more credits than shorter recordings.
Preview and Download the Cleaned Audio
When processing is complete, listen to the result in your browser and download the processed 192 kbps MP3 if it is suitable for your project. If the result is not satisfactory, try a cleaner source recording. Background noise that overlaps heavily with the speaker’s voice is more difficult to reduce without affecting speech quality.
What Types of Noise Can Be Reduced?
The tool works best on steady, low-level noise that remains below the speaker’s voice. Effectiveness varies with every recording, and no category is guaranteed to be removed completely.
Fan and Air-Conditioner Noise
Steady ventilation noise may be reduced when it remains quieter than the main speaker. This is common in podcasts, meetings, and home recordings.
Hum and Hiss
Low electrical hum and consistent background hiss may be reduced, especially when the sound remains stable throughout the recording.
Light Static Noise
The tool may reduce light static. Severe crackling, damaged recordings, and intermittent digital glitches may require specialized audio restoration.
Room and Ambient Noise
Low-level room ambience may be reduced to make speech easier to hear. Loud traffic, nearby conversations, music, and sudden sounds are more challenging.
Noise Reduction for Everyday Recordings
Clean up authorized speech recordings for publishing, review, education, and team workflows.
Podcasts and Interviews
Clean up podcast conversations, remote interviews, introductions, and spoken segments affected by room noise, fans, or other low-level background sounds.
Video Voiceovers and Social Content
Improve recorded narration for product demonstrations, tutorials, YouTube Shorts, Instagram Reels, and other social content. The current page accepts audio rather than video, so extract the audio track before uploading it.
Lessons, Meetings, and Training Material
Reduce distractions in recorded lectures, online lessons, meeting audio, tutorials, and internal training so spoken information is easier to review and understand.
Voice Notes and Speech Workflow Preparation
Create a cleaner working copy of voice notes or lightly noisy recordings before reviewing, transcribing, or using them in another authorized voice workflow. Denoising does not guarantee downstream accuracy or generation quality.
How to Get Better Audio Denoising Results
Audio noise reduction works best when the main voice is already distinguishable from the unwanted sound. An audio denoiser cannot reconstruct speech information that was never captured clearly.
Use the Original Recording
Start with the original or highest-quality file instead of a copy that has been repeatedly compressed.
Keep Speech Prominent
Record with the microphone close to the speaker and keep the voice louder than the surrounding noise whenever possible.
Avoid Clipping and Distortion
Severely clipped or distorted speech cannot be fully restored by running the recording through noise reduction.

Listen to the processed file before publishing or using it in another workflow, especially where noise overlaps with speech.
Audio Denoiser vs. Audio Enhancer vs. Vocal Isolator
These tools may appear under related audio-cleanup searches, but they solve different problems. Echora Audio Denoiser processes uploaded recordings; it is not a real-time microphone filter, music separator, or complete mastering suite.
Audio Denoiser
Reduces unwanted background noise in a recording while trying to preserve clear, natural speech.
Audio Enhancer
A broader category that may include loudness, equalization, dynamics, clarity, mastering, and other processing.
Vocal Isolator
Separates vocals from music or another mixed audio track instead of removing general recording noise.
Real-Time Noise Suppression
Reduces microphone noise during calls, live streams, gaming, or recording rather than processing an uploaded file.
