How do I remove background noise from audio?

Load the file into PumpyDumpy2AudioMaster and run the denoise pass. It uses DeepFilterNet, an AI denoiser, to strip background hiss, hum, and room noise while keeping the voice or instrument natural. The strength is adjustable, and everything runs locally on your PC with no upload.

What kind of noise can it remove?

Steady background noise like hiss, hum, fan and air-conditioner noise, and room tone, plus the faint digital hiss that AI music exports sometimes carry. It is most effective on consistent background noise; very loud, intermittent sounds like a door slam are harder for any denoiser to remove cleanly.

Will denoise make my audio sound watery or underwater?

That artefact comes from pushing noise reduction too hard. PumpyDumpy2AudioMaster lets you set the denoise strength and preview the result, so you can remove the noise while keeping the audio natural. DeepFilterNet is also designed to preserve speech and vocal detail better than older noise gates.

Does it work on podcasts and recordings, not just music?

Yes. DeepFilterNet is strong on speech, so it works well on podcast recordings, voiceovers, interviews, and spoken-word audio, as well as sung vocals and full music tracks. If you can load the file, you can denoise it.

Remove Background Noise from Audio, Fully Offline

Q: Does the noise remover upload my audio?

No. PumpyDumpy2AudioMaster is a fully offline desktop app. The DeepFilterNet model is bundled into the installer, so your audio is denoised entirely on your machine - no upload, no cloud queue, and no account holding your files.

Q: Is the noise remover free?

Yes. PumpyDumpy2AudioMaster is free to download and use, with a light watermark on exported audio. Pro removes the watermark and grants a commercial-use license for $20/month or $200/year, and the same subscription also unlocks PumpyDumpy2Visual.

Strip hiss, hum, and room noise from recordings, vocals, podcasts, and AI audio on your own PC - with adjustable strength and no upload.

Background noise is the fastest way to make audio sound amateur. A vocal recorded in an untreated room picks up hiss and air-conditioner hum; a podcast take has a constant background hum; even AI music exports can carry a faint digital hiss. PumpyDumpy2AudioMaster (PD2AM) removes that noise locally on your PC, so your audio never gets uploaded and there is no limit on how many files you clean.

It uses DeepFilterNet, an AI denoiser that is especially strong on speech and vocals, to separate the wanted signal from the background and remove the noise while keeping the voice natural.

What It Removes

Hiss: the constant high-frequency background found on many recordings.
Hum and rumble: low-frequency electrical hum and room rumble.
Room and ambient noise: fans, air conditioning, computer noise, and general room tone.
Digital hiss on AI exports: the faint noise floor some AI tracks carry.

It works best on steady, consistent noise. Loud one-off sounds, like a door slam, are hard for any denoiser to remove cleanly.

AI Denoise Without the Watery Sound

The classic problem with noise reduction is overdoing it: push too hard and the audio turns watery and underwater. PD2AM gives you an adjustable denoise strength and a preview, so you can dial in just enough to clear the noise while keeping detail. DeepFilterNet is built to preserve speech and vocal clarity better than old-style noise gates, so even at meaningful strength the result stays natural.

Not Just Music: Podcasts, Voiceovers, and Recordings

Because DeepFilterNet is so strong on speech, the denoiser is just as useful outside music. Clean up podcast episodes, voiceovers, interviews, and spoken-word recordings, as well as sung vocals and full songs. If you can load the file, you can denoise it - the workflow is the same: load, set the strength, preview, export.

Offline and Private

The DeepFilterNet model is bundled into the installer, so your audio is denoised entirely on your machine. There is no upload, no cloud queue, and no account holding your recordings - which matters for unreleased tracks, client work, and private recordings. It is also faster: no upload, no download wait, no daily cap.

Part of a Full Audio Pipeline

Denoise is one stage of a complete workflow. PD2AM can also repair vocals (de-ess, declick, breath control), split a song into stems, master the mix to streaming loudness, and export a delivery pack. It also bridges to its companion app PumpyDumpy2Visual for turning a finished track into a music video.

Pricing

PumpyDumpy2AudioMaster is free to download and use, with a light watermark on exported audio. Pro removes the watermark and grants a commercial-use license for $20/month or $200/year. The same Pro subscription also unlocks PumpyDumpy2Visual, so you get the audio toolkit and the music-video app for one price. Already a PumpyDumpy2Visual Pro subscriber?
