Frequently Asked Questions
What is the best software to remove noise from audio?
It depends on the workflow. If you want a professional, installable toolchain with filters you tune, Audacity is a free and capable desktop option. If you want to remove noise from audio without installing software — one file, a browser, and a result in minutes — SimpleClean is the online choice. Both are legitimate; the split is about whether you want to learn a desktop toolchain or get a cleaned recording today.
Do I need to download or install anything?
No. SimpleClean runs entirely in your browser: upload one supported file, wait for processing, and compare Original with Cleaned playback before downloading. There is no installer, no plugin, and no desktop configuration — this is the core difference from desktop software like Audacity.
Is SimpleClean really free?
Comparing Original with Cleaned playback is free. Every account receives a one-time lifetime Starter grant of 30 cleanup minutes that never resets — it is used first to unlock full-output downloads. After that, continue with a subscription (from $3.50/month for 10 hours) or pay-as-you-go hours (from $2.99 for 5 hours) that never expire. There is no free trial clock hiding behind a card form: the 30 minutes are yours, once.
Which is better, SimpleClean or Audacity for removing background noise?
Audacity is better when you want full control: noise profiles, manual thresholds, batch workflows, and a desktop file pipeline. SimpleClean is better when you want the noise gone without installing software or tuning filters. They do not conflict — this page is for the second group. If your dominant problem is echo, reverb, wind, clipping, or overlapping speech, neither tool is the right one; see the diagnostic guide on the blog.
What audio formats can I upload?
SimpleClean accepts MP3, WAV, M4A, AAC, FLAC, OGG, and OPUS audio, plus MP4, MOV, MKV, WebM, and AVI video. The default limit is one file up to 500 MB and 15 minutes per run. Audio output is MP3; video output is MP4.
Does noise removal damage the voice?
SimpleClean's AI model targets steady background noise — hiss, hum, fan noise, and room tone — while keeping the speech band natural. Always use the Original vs Cleaned comparison before downloading and listen for a metallic or watery edge. Transient spikes such as hand claps or door slams are brief events, not steady noise, and are handled less reliably. Keep the original file so you can return to it if the cleaned version sounds less natural.
