Free audio noise removal for Windows — local AI, no upload
FrameShift removes background noise from audio and video files using DeepFilterNet3, running entirely on your machine. No upload, no account, no subscription. Right-click any audio or video file in Windows Explorer and get a clean, denoised version in seconds.
Two actions — audio and video
Denoise audio files
Right-click any audio file (MP3, WAV, FLAC, AAC…) and remove background noise. Choose the denoising strength, enable stereo mode if needed, and get a clean audio file next to the source.
Denoise a video's audio track
Denoise the audio track of a video without re-encoding the video stream. The output is a new video file with a clean audio track and the original video quality unchanged.
Common use cases
Podcast and voice recordings
Remove room noise, fan hum and HVAC rumble from podcast episodes, interview recordings and voice-overs recorded in non-treated environments.
Meeting and call recordings
Clean up background noise from Zoom, Teams or phone call recordings to make them easier to transcribe or share.
Lecture and tutorial audio
Remove keyboard clicks, air conditioning and ambient noise from screen recordings and educational content before publishing.
Field recordings and interviews
Reduce wind, traffic and crowd noise from audio recorded outdoors or in noisy environments.
Why denoise locally?
No upload, complete privacy
Adobe Enhance and similar cloud tools upload your recordings to their servers. FrameShift processes everything locally — your audio never leaves your machine.
Free, no limits
No subscription, no per-minute charge, no free tier cap. FrameShift is open source and completely free regardless of how much audio you process.
Works on any Windows PC
DeepFilterNet3 runs on CPU — no GPU or special hardware required. Works on any Windows 10/11 machine.
Right-click from Explorer
No app to open, no import. Right-click any audio or video file in Explorer and the denoised version appears next to the source.
Video: audio only, no re-encode
When denoising a video file, only the audio track is processed. The video stream is copied as-is — no quality loss, no extra encoding time.
Adjustable strength
Control the denoising intensity to balance between noise reduction and preserving the natural sound character of the recording.
How it works
Right-click any audio or video file in Windows Explorer and choose FrameShift → Remove Noise (Audio) or Remove Noise (Video).
Adjust settings — set the denoising strength and enable stereo mode if your recording is stereo.
Processing runs locally — DeepFilterNet3 processes the audio on your machine at 48 kHz, frame by frame.
Get your clean file — the denoised output is saved next to the source with a unique name. For video, the audio track is replaced and the video stream is untouched.
Frequently asked questions
Can I remove background noise from audio for free on Windows without uploading?
Yes. FrameShift removes background noise from audio and video files locally on Windows using DeepFilterNet3. It is completely free, requires no upload, no account and no internet connection after the model is downloaded once.
What AI model does FrameShift use for noise removal?
FrameShift uses DeepFilterNet3 ONNX exports — an open-source neural network trained specifically for speech enhancement. It operates natively at 48 kHz and handles a wide range of background noise types.
Can FrameShift remove noise from a video file?
Yes. The Remove Noise (Video) action denoises the audio track of a video without re-encoding the video stream. The output is a new video file with the denoised audio and the original video quality completely intact.
Does audio noise removal require a GPU?
No. DeepFilterNet3 runs on CPU only and works on any Windows 10/11 machine. No GPU, no special hardware required.
What types of noise can FrameShift remove?
DeepFilterNet3 handles common noise types including ambient room noise, fan and HVAC hum, keyboard clicks, street noise, and background chatter. It works best on recordings where a clear speech signal is present.
How does FrameShift compare to Adobe Enhance or Krisp?
Adobe Enhance is a cloud service that uploads your audio. Krisp requires a subscription and runs as a real-time filter. FrameShift is completely free, processes audio locally on any Windows machine, and works on existing recordings — no subscription, no upload, no specific GPU required.
