Frequently asked questions

What kind of sounds can AI background noise removal adjust?

Captions’ noise remover is designed for the kinds of noises that show up in everyday recordings. It automatically detects the vocal track, and removes other noises that distract from audio clarity. Common noises include HVAC systems, microphone hiss, echo, reverb, wind and background speakers. Removing them makes your audio easier to understand, keeping viewers engaged.


How can I remove background noise from videos on my iPhone?

Editing videos on your iPhone is simple with the Captions iOS app. Just upload your video and tap “Denoise” to remove background noise, then export the edited project to your camera roll.     


What video formats does Denoise support?

Captions' Denoise feature supports MOV, MKV, AVI, MP4, GIF, QuickTime, and FLV files.   


Will using Denoise affect video quality?

Filtering out background noise with Denoise won’t degrade the quality of your video, and the finished product will sound just like it came from a recording studio. Because Captions is an all-in-one video editor, you can even upgrade your video quality while you edit. You’ll get to pick details like resolution and file size when you export. 


Does denoising affect the quality of my voice in the video?

Captions' AI is trained to preserve vocal frequencies while removing background noise. In most cases, your voice will sound cleaner and more present after denoising, not thinner or processed. You can preview the result before exporting. 


What type of content can I remove background noise from?

AI-powered background noise removal works best on videos with consistent volume and easy-to-distinguish audio. Videos with clearly audible subjects, like vlogs, interviews, and webinars, are ideal for applying the Denoise feature.   

If the volume of the sound you want to filter out overlaps with the audio you’re keeping, noise reduction tools like Denoise may have a hard time telling the difference between the two. For example, trying to filter out the sound of a rock band that’s overpowering the person speaking might not result in the sound quality you’re hoping for. Be sure to preview the edited video before exporting. If the audio isn’t quite right, disable Denoise and try creating the video again.


What makes top-quality sound in videos?

Video editing apps like Captions or Adobe Premiere Pro and audio editors like Audacity or Adobe Audition are great for eliminating unwanted sounds in movies and audio clips. 

To make the sound quality even better, be mindful of the environment you’re recording in, doing what you can to reduce the noise the mic picks up. Strong wind, for example, might completely drown out the sound of your voice, requiring you to make a voiceover audio recording.
