Denoise and EBU R128 loudness-normalize any video's audio in one pass — local processing, no watermark, no monthly cap.
Most audio cleanup tools do one or the other. ViralMint runs RNNoise denoising AND EBU R128 loudness normalization in a single FFmpeg pass — your output is clean of background hum AND mastered to broadcast loudness without two separate workflows.
Loudness normalization to a peak target prevents clipping but doesn't fix average loudness. EBU R128 normalizes to integrated loudness (LUFS) — the standard YouTube, Spotify and broadcast TV all use. Your audio sounds consistent across videos and across platforms.
Adobe Podcast Enhance is free but cloud-only — your audio leaves your machine and waits in their queue. Krisp and Auphonic are paid subscriptions ($8–32/month). ViralMint runs FFmpeg locally; nothing leaves your computer, processing starts immediately, the output has no watermark.
Launch ViralMint and click Tools in the sidebar, then Audio Enhance. The tool accepts mp4, mov, mkv, mp3, wav, m4a and most common audio/video formats.
Drag your video or audio file onto the upload zone. ViralMint immediately analyzes the loudness profile and detects average background-noise levels.
-14 LUFS (YouTube + Spotify default), -16 LUFS (podcast standard), -23 LUFS (EBU broadcast TV). Default -14 is right for 95% of social-media content.
Click Render. ViralMint runs RNNoise + the EBU R128 normalization filter in a single FFmpeg pass. A 10-minute video typically processes in 1–2 minutes.

Peak normalization lifts the loudest sample to a target — fine if your audio is already balanced. EBU R128 measures the integrated loudness (the LUFS unit) across the entire track and adjusts to a consistent average. EBU is what YouTube, Spotify and broadcast platforms use to balance volumes between videos. Use EBU.
-14 LUFS integrated. YouTube auto-normalizes uploads to about -14 LUFS, so mastering at that target means your video plays at the level YouTube expects with no automatic gain reduction. -14 is also the default in ViralMint's tool. For podcasts use -16 LUFS; for broadcast TV use -23 LUFS.
RNNoise is trained specifically to preserve speech while removing steady background noise (HVAC, computer fans, room hum, traffic). It struggles with sudden loud noises (door slams, dog barks) — for those, the desktop app's Smart Video pipeline can also crossfade through the disruption. For 95% of indoor recordings RNNoise is the right choice.
It's optimized for speech. Music gets normalized correctly (loudness leveling works on any audio) but the denoising step can subtly alter musical texture. For pure music files, run normalization only by setting the denoise toggle off in the desktop app.
Drop multiple files in sequence — each is a separate job and they queue automatically. The Jobs page shows progress for all of them.
The Audio Enhancer ships inside the free ViralMint desktop app — no subscription, no watermark, no per-minute cap. Download once, use on as many videos as you want.
