Let’s compare 7 of the best AI that adds sound effects to video:
Tools like AI that adds sound effects to video are completely transforming brand UGC marketing. Now, both brands and creators can generate AI-driven UGC videos, increasing their output 10x and reducing 80% of their campaign costs.
This may sound far-fetched, but thanks to the rapid advancement of AI, the world of UGC has changed overnight. With tools like Argil, brands can turn testimonials and written reviews into branded video content starring AI influencers, complete with sound effects, B-roll and automated captions.
Not only this, but with a single short script, UGC content creators can scale their output tenfold by creating their very own digital clone. With Argil’s lifelike avatars, creators can generate videos in minutes, all without having to pick up a camera.
This is good news across the board. Creators are better able to monetize their personal brands and scale their output, while brands can create UGC-style content without having to navigate reshoots, budgets, logistics or wait times.
Brands using AI UGC approaches can also localize their video content across multiple languages, allowing them to reach new and untapped markets, while our A/B testing function allows them to test multiple voices, hooks and sound effects without creating a new video everytime.
Using our AI video tool, companies and content creators can maximize engagement while minimizing their manual workload – and our AI clones are so realistic, you won’t need to sacrifice authenticity or quality.
Agencies that add sound effects to video with UGC are seeing improveements in conversion rates and engagement due to AI-driven A/B testing, and viewers are able to retain information from video ads long after seeing them.
ElevenLabs' sound effects generator is an innovative AI tool that allows users to create custom audio effects using simple text prompts, with 1000 seconds of audio available for new users to want to try it risk-free.
Users can create five different sound samples for each prompt, so you’ll have a few different options to choose from when it comes to finalizing your video. The tool also provides soundboard access – an impressive feature that lets you generate custom audio effects from scratch.
The downside is that online reviews indicate mixed quality results, with some users reporting that the sounds were unusable in the video content.
Overall, as we’ve reported previously, ElevenLabs is a fantastic AI voice cloning tool. However, its sound effects feature seems to have been rushed to market, with several workflow and feature issues that impact its ability to deliver.
My Edit offers a free AI sound effect generator where users can create custom audio, such as a baby laughing, pouring rain with thunder and people talking or applauding, all from stext prompts.
Positioned as an all-in-one AI tool for creating high-quality images, audio and video, MyEdit is a completely free tool, making it an attractive choice for new and smaller content creators.
However, the platform has some limitations and seems to have quite basic audio editing features such as text-to-speech, background noise removal and voice changing.
For content creators looking for super-efficient workflows and professional-grade sound effects, My Edit is a good free starting point, but it won’t be able to scale to meet your growing production and personalization needs.
Plugger AI is locked behind a $19 per month subscription for the Lite package, so it isn’t cheap in comparison to other AI that adds sound effects to video tools like MyEdit.
The Lite package includes 100 audio files per month, and users can fine-tune the intensity, duration and pitch of AI-generated sounds to match their specific needs.
Plugger has a limited online presence, and there aren’t many reviews. For this reason – and because of its high price point – it’s difficult to recommend this tool to serious content creators looking to streamline and enhance their video production.
Unlike the other tools we’ve covered so far, LoudMe focuses primarily on AI music generation rather than specific sound effects for video content, making it a good choice for music producers, but not so much for content creators.
While LoudMe can be valuable for background tracks, it doesn't address the specific requirements of most content creators who need custom sound effects that match their video content. Those creators would likely need to supplement this tool with additional AI that adds sound effects to video.
Developed by Descript, this tool is primarily known for its superior voice cloning capabilities, rather than general sound effects generation. If you’re looking for general AI that adds sound effects to video, this may not be the ideal choice.
While it’s great for voiceovers, Lyrebird AI is more suited to audio-only creators, such as audiobook producers, podcasters and one-off voiceover projects, rather than video creators.
Filmora's AI that adds sound effects to video is called Wondershare. This tool is primarily aimed at professional video creators who want AI sound effects, high-quality audio generation and royalty-free content.
Like with the other tools mentioned, it’s easy to generate custom sound effects by entering simple text prompts and descriptive keywords. You can then set the duration and quantity of your sound effects, preview the audio or download the file directly into Filmora’s editing suite.
The only downside is that using Wondershare means being tied to Filmora's ecosystem, which can be a little basic in terms of video creation so may not be suited to personality-driven creators who need authentic, highly personalized content.
Many creators are looking for AI that adds sound effects to video without realizing they need a full-scale video content solution.
The best AI tools don’t just fill in the gaps in your production cycle — they help you build an entire ecosystem, where dynamic sound mapping matches AI-generated voiceovers and clones, with background effects and imagery.
Using disconnected tools can lead to awkward mismatches in editing, along with inconsistencies in tone or style. If you want to stay on-brand and retain your identity across dozens of videos, it’s best to limit yourself to one video generation and audio tool.
Argil provides just this. We integrate sound design and AI voiceovers into the scripting process, applying tailored ambient noise, music and complementary video transitions. With advanced lip-syncing technology, we also make sure that audio and voiceover are fully synchronized with avatar appearance, speech styles and mannerisms across multiple different languages and dialects.
You can also customize your videos and add branded music, auditory cues and sound effects to enhance your brand identity. With Argil, you don’t need additional tools like Audacity or Descript, and you don’t need to worry about tricky integrations or editing skills.
Unlike lesser tools, Argil’s AI that adds sound effects to video provides everything you need in one place — from background music to sound effects, visual B-roll, dynamic captions and AI avatars.
When comparing AI that adds sound effects to video, you should keep in mind that the more tools you have in your tech stack, the more fragmented your workflow will be. Using lots of different tools together can create inefficiencies and inconsistencies in your work, which can make things more difficult and time-consuming in the long-run.
For video content creators, Argil is the best solution because it offers a holistic, all-on-one platform for video creation, editing and audio. With just a single text prompt, you can create social-ready videos in under ten minutes, complete with background music, dialogue, automatic B-roll and visual transitions.
Our AI is more like a co-pilot than a tool, automatically handling sound optimization alongside video generation and editing, so you can focus on more creative and strategic tasks. Our platform completely eliminates the need for separate audio tools, so you can do everything in one place
If you need a specific audio sound that isn’t available in our AI editing suite, you can simply download it as an MP3 from YouTube or elsewhere on the internet and then upload it to Argil. From scripting to sharing, the video production process couldn’t be easier.
If you’re a content creator, marketer or entrepreneur, the best way to maximize the value of your content is to employ a “create once, distribute everywhere” approach — i.e., repurposing. Repurposing means taking one main piece of content (such as an eBook or long video) and creating short snippets or pieces of content to share across multiple platforms.
For example, you might produce a free fitness PDF to give your followers an insight into your work as a health coach. Using Argil, you can convert this PDF into several short videos using your AI avatar, who can be walking, working out, or showcasing a branded product.
These videos will be fully polished and edited, complete with sound design and AI voiceover — we can clone your voice so your videos sound exactly like you speaking, even if you’re using an avatar — and shared across TikTok, Reels, YouTube Shorts and X. You could even create a short video for your website homepage encouraging users to download your PDF.
If you send out a regular newsletter, you can also maximize its value by creating short video clips to highlight important or engaging content. Using reusable audio elements from Argil’s library, you can make your videos super engaging with hooks, jingles and background music. You can even test different video variants to find out which sound effects your audience prefers.
Using this approach, creators can build a library of videos and build a scalable presence across multiple platforms while limiting their manual workload.
Monetizing content has never been easier or more lucrative, whether you’re creating UGC-style videos or building a personal brand. By making the most of AI that adds sound effects to video tools like Argil, you can streamline your content production workflows and create multiple revenue streams, all without spending hours filming and editing every day.
Here are just some of the ways you can monetize audio-enhanced video content:
Each platform offers its own direct revenue option, such as TikTok’s creator fund, with an average payout of $0.03-$0.04 per 1000 views, or YouTube’s ad revenue.
Because it can be difficult to monetize content directly, most full-time content creators have multiple revenue streams in addition to the money they make directly through TikTok or YouTube, such as bonus content, branded products, subscriptions and sponsored ads.
Affiliate marketing is another effective way to earn money from videos made with AI tools. Using Argil, it’s possible to create dozens of videos with affiliate links using a pre-trained avatar and automatic editing, and to showcase and link products directly.
Once you’ve built a social following, you’ll be able to offer your services to brands in the form of sponsored content. Sponsored posts can also bring in $200-$2500 (and beyond!) for established creators, but often the payout depends on engagement — making your editing and production tools more important than ever.
Luckily, Argil makes it easy to create high-performing videos. Our editing suite offers smart suggestions to improve your content, while pulling out viral hooks and allowing you to customize and optimize both the visuals and the back-end SEO.
Another way to monetize videos is through paid subscription-based channels like Patreon. Here, you can upload exclusive videos for subscribers that sit behind a paywall and bring in monthly revenue. You’ll need a social following or podcast audience so you can advertise your Patreon content.
You may also decide to sell your videos as products (for example, educational or fitness videos) through your content library or website.
You can sell videos created with AI that adds sound effects to video tools to agencies or businesses, creating a tiered product list for videos with premium sound effects or full musical scoring.
You may also decide to sell video templates or soundscapes so companies can make their own video content. Just make sure you’re properly licensed to sell video templates to other brands.
