They walk you through spectral editing, noise gates, and menus five layers deep in software you&#8217;ve never opened. For a barking dog or a humming AC, that&#8217;s overkill.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">The truth is simpler.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">How you remove background noise comes down to one thing: whether you&#8217;re on a live call right now, or cleaning up a file you already recorded. Get that distinction right and the fix is usually one setting or one click, not an afternoon of editing.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>This guide covers both<\/b><span style=\"font-weight: 400;\">. We&#8217;ll start with real-time removal for calls and meetings (the fastest fix, and the one most people need), then move to cleaning up recorded audio and video. If you specifically want a ranked list of tools, see our roundup of the <\/span><a href=\"https:\/\/krisp.ai\/blog\/best-noise-cancelling-app\/\"><span style=\"font-weight: 400;\">best noise cancelling apps<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Otherwise, read on and you&#8217;ll know exactly what to do by the end.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">What causes background noise (and why it wrecks your audio)<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Background noise is any unwanted sound that gets picked up alongside your voice. It usually falls into a few buckets:<\/span><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Steady\/ambient noise:<\/b><span style=\"font-weight: 400;\"> fans, air conditioning, refrigerator hum, computer whir. Constant and low, which makes it easy for AI to model and remove.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Sudden\/impulsive noise: <\/b><span style=\"font-weight: 400;\">keyboard clicks, door slams, dog barks, dishes. Harder, because it&#8217;s unpredictable.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Environmental noise: <\/b><span style=\"font-weight: 400;\">traffic, wind, caf\u00e9 chatter, kids in the next room.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Electronic noise:<\/b><span style=\"font-weight: 400;\"> mic hiss, buzz, and hum from cheap cables or interference.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Echo and reverb: <\/b><span style=\"font-weight: 400;\">your voice bouncing off hard walls in an empty room.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Noise doesn&#8217;t just annoy listeners. On a call, it forces everyone to work harder to follow you, which drains attention fast. Around six in ten employees say digital tools and noise make work more stressful, <\/span><a href=\"https:\/\/www.unily.com\/resources\/blogs\/unily-research-exposes-workplace-digital-noise-crisis\"><span style=\"font-weight: 400;\">according to Unily&#8217;s Digital Noise Impact Report<\/span><\/a><span style=\"font-weight: 400;\">. In a recording it&#8217;s worse: every replay carries the same distraction, and transcription tools mangle words buried under noise.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">The two ways to remove background noise<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">There are only two real approaches, and picking the right one saves you the most time.<\/span><\/p>\n<p>&nbsp;<\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Real-time (during the call or recording). <\/b><span style=\"font-weight: 400;\">Software filters noise from your mic and speaker as you talk, so the other side, and any recording, only ever hears your clean voice. Nothing to edit afterward. This is the right choice for meetings, calls, live streams, and voice recording.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Post-recording (after the fact). <\/b><span style=\"font-weight: 400;\">You take a finished audio or video file and run it through a noise remover or editor to clean it up. This is what you need when the recording already exists and the noise is baked in.<\/span><\/li>\n<\/ol>\n<p><b>Rule of thumb:<\/b><span style=\"font-weight: 400;\"> if you can fix it before it happens, do that. Real-time removal means you never have to salvage a bad recording in the first place.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How to remove background noise in real time (calls &amp; meetings)<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">This is the fastest way to remove background noise, and it works across every app instead of one at a time.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Remove background noise with Krisp (one click)<\/span><\/h3>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-23591\" src=\"https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-scaled.png\" alt=\"\" width=\"2560\" height=\"1231\" srcset=\"https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-scaled.png 2560w, https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-300x144.png 300w, https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-380x183.png 380w, https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-768x369.png 768w, https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-1536x738.png 1536w, https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-2048x985.png 2048w, https:\/\/krisp.ai\/blog\/wp-content\/uploads\/2024\/11\/Krisp-AI-Noise-Cancellation-600x288.png 600w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">Krisp sits between your microphone and whatever app you&#8217;re using, stripping out background noise, echo, and even other voices before they reach the call. It works at the system level, so the same clean audio flows into Zoom, Teams, Google Meet, Slack huddles, phone calls, and recordings.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Here&#8217;s how to set it up:<\/span><\/p>\n<p>&nbsp;<\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Download and install Krisp<\/b><span style=\"font-weight: 400;\"> for your operating system, then open the app.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Select your real microphone <\/b><span style=\"font-weight: 400;\">and speaker as Krisp&#8217;s input and output devices.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Toggle on noise cancellation for the microphone<\/b><span style=\"font-weight: 400;\"> (and the speaker, if you want to mute noise coming from other people on the call).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>In your calling app&#8217;s audio settings,<\/b><span style=\"font-weight: 400;\"> choose &#8220;Krisp Microphone&#8221; and &#8220;Krisp Speaker&#8221; as the devices.<\/span><\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">That&#8217;s it. From then on, every call routes through Krisp automatically. The difference is stark in practice. On a bench next to a busy street, with buses pulling away and someone talking two feet over, the person on the other end just hears you. The engine noise and the chatter don&#8217;t make it through.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Krisp&#8217;s noise cancellation also runs on-device: your audio is processed locally on your machine rather than sent to a server. If you&#8217;re on client or confidential calls, that&#8217;s a real privacy difference from cloud-based cleaners.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>One honest limitation: <\/b><span style=\"font-weight: 400;\">noise cancellation is the free part. Krisp&#8217;s meeting-assistant features (recording, transcription, and summaries) sit behind a paid plan after a short trial, so teams that want those will pay.<\/span><\/p>\n<p>&nbsp;<\/p>\n<div class=\"text_center cta_shortcode\">\n<div class=\"button btn--dark\">\n        <a href=\"https:\/\/\/app.krisp.ai\/sign-up\/\">Try Krisp for Free<\/a>\n    <\/div>\n<\/div>\n<h3><span style=\"font-weight: 400;\">Built-in noise suppression in Zoom, Teams, Meet &amp; Discord<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Most calling apps have basic noise suppression built in.

A system-level tool applies the same clean audio to all of them at once, which is why it wins if you bounce between platforms.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How to remove background noise from an audio recording<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">If the recording already exists, you&#8217;re cleaning it after the fact. The good news is that AI has made this fast.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Using an AI audio cleaner<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">AI noise removers have replaced the old manual workflow almost entirely. The process is roughly the same across most of them:<\/span><\/p>\n<p>&nbsp;<\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Upload your audio file<\/b><span style=\"font-weight: 400;\"> (MP3, WAV, M4A, and so on).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Let the AI detect <\/b><span style=\"font-weight: 400;\">and strip out the noise automatically.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Preview the result, <\/b><span style=\"font-weight: 400;\">and adjust the strength if the tool lets you.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Download<\/b><span style=\"font-weight: 400;\"> the clean file.<\/span><\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">There&#8217;s no noise profile to sample and no filters to tweak. Most tools handle hiss, hum, wind, and background chatter in one pass, and many reduce echo and reverb too.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">If clean recordings matter to you regularly (interviews, podcasts, voice notes), the smarter move is to remove the noise while you record, so you never have to clean files at all. A tool that captures clean audio at the source, like Krisp&#8217;s <\/span><a href=\"https:\/\/krisp.ai\/meeting-recording\/\"><span style=\"font-weight: 400;\">meeting recording<\/span><\/a><span style=\"font-weight: 400;\">, hands you a noise-free file the moment you stop recording.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">The older way: manual editing<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Free editors like Audacity can remove background noise too. You sample a &#8220;noise profile&#8221; from a silent part of the clip, then apply it to the whole thing. It works, but it&#8217;s fiddly, easy to overdo (voices start sounding underwater), and slow next to a one-pass AI tool. Reach for it only if you already know your way around an editor.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How to remove background noise from a video<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Removing background noise from a video is the same problem as audio: the noise lives in the audio track. You have two options.<\/span><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Clean the audio track in your video editor. <\/b><span style=\"font-weight: 400;\">Most editors have a denoise feature. In Adobe Premiere Pro, the Essential Sound panel has a &#8220;Reduce Noise&#8221; slider and a DeNoise effect; DaVinci Resolve has &#8220;Voice Isolation&#8221; on the Fairlight page. If you already edit in one of these, that&#8217;s your fastest path.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Record clean audio in the first place. <\/b><span style=\"font-weight: 400;\">If the video hasn&#8217;t been shot yet (a talking-head clip, a webinar, a screen recording), running your mic through real-time noise cancellation means the captured audio is already clean, with no denoising pass required.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">For talking-head and meeting-style video especially, capturing clean audio up front beats fixing it later every time. The moment you re-record a &#8220;just one more take&#8221; because a truck drove by, you&#8217;ve already spent more time than prevention would have cost.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How to remove specific noises<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Fan \/ AC \/ hum:<\/b><span style=\"font-weight: 400;\"> Steady noise is the easiest to remove. Real-time cancellation kills it instantly, and any AI cleaner handles it in one pass.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Wind: <\/b><span style=\"font-weight: 400;\">Notoriously hard, because it overlaps with speech frequencies. AI denoisers trained on wind do best, and a physical mic windscreen helps at the source.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Keyboard clicks: <\/b><span style=\"font-weight: 400;\">Impulsive and sharp. Modern AI noise cancellation is trained specifically on typing and removes it cleanly, even mid-sentence.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Echo \/ reverb: <\/b><span style=\"font-weight: 400;\">Not &#8220;noise&#8221; exactly; it&#8217;s your own voice reflecting back. Use a de-reverb or echo-removal setting. Most AI cleaners and real-time tools include one.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Background voices \/ chatter: <\/b><span style=\"font-weight: 400;\">The hardest case. Voice-isolation tools that lock onto the primary speaker are the fix.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Hiss \/ buzz: <\/b><span style=\"font-weight: 400;\">Usually electronic.
