About This Tool
Transgate's free background noise remover uses FFmpeg's built-in audio FFT denoiser (afftdn) to clean stationary noise from any audio or video file. Processing runs on our secure servers, and your file is deleted immediately after you download the result.
For video files, only the audio channel is processed. The video track is stream-copied without re-encoding, so quality and sync are perfectly preserved. Supports MP3, WAV, M4A, AAC, OGG, FLAC, OPUS, MP4, MOV, AVI, WMV, WebM, and MKV.
