Six AI Audio Cleaning and Transcription Resources for Video and Animation Content Creators

AI Audio Cleaning Robot. Image by TET and Leonardo.ai
While AI applications may have been receiving a lot of bad press lately in the visual arts, there are definitely times when AI is a game changer, in a good way, for more mundane applications like audio cleaning and transcribing.

Maybe there's some militant audio engineers or transcribers out there who just love what they do but the ability to give an audio file to an AI, and have it automatically improve the quality of sound or transcribe an hour or more of speech in seconds, is pure magic.

Sure the AI doesn't always get it right, particularly with transcribing, but it's pretty good. Plus, correcting a few short falls is certainly better than doing all the work yourself.

I recently recorded a thirty minute video with audio that was borderline awful. It was clear enough to understand but I hadn't been able to filter out the static noise of the microphone, and it would distort on the louder sections, just enough to notice, even though the levels were well under the clipping threshold.

Nothing I did in post would fix it so I decided to see what AI audio cleaning services were out there (and of course find out if there were any free services).

Clean Voice AI

Sound Wave Before and After Cleaning.
I'm leading with Clean Voice AI because it was the service I used to fix my audio. Your first 30 minutes is completely free (which was all I needed).

Clean Voice over delivers, not just fixing terrible audio but also removing dead air, 'ums' and 'ahs' (as well as other mouth sounds), and more.

Although I didn't try Clean Voice's audio transcribing, its inclusion  makes the site a great, one stop service, for many of your audio needs. It's particularly targeted at podcasters including a number of free tools for them like their Podcast Episode Title Generator.

Clean Voice AI is browser based. Subscription pricing seems quite reasonable to me but what I most liked is that you can pay as you go as well.

Audo Studio

If all you need is just a straight up audio cleaner that can remove almost any unwanted background noise then Audo Studio is a browser based application that may be what you're looking for.

Some examples of the kind of noises they can fix include background restaurant noise, bird squawks, dog barking and more. Audo Studio can also auto adjust volume levels so your voice can be heard.

Another nice feature is that you can upload video files for audio cleaning. No need to separate your audio just to use the service. Which may be useful if you're wanting to fix audio on older completed videos.

Audo Studio is subscription based but they do have a free plan that gives you 20 minutes of audio cleaning per month.


Deciphr

Transcript Sample from Deciphr
Another browser based AI service targeting podcasters (but also can process video files) Deciphr is a one stop shop for turning audio into all kinds of text. 

Not limited to transcribing, it can also generate show notes, show summaries, pull out quote highlights, create captions for social media posts, list keywords for SEO and, on a paid plan includes the creation of audiograms and video reels (highlighted audio and video for social media). 

All output is organized on a sharable page with a nice headline or you can download everything as a Word Document.

Deciphr has a flexi-free plan that gives you 40 minutes of audio/video upload to get started then it's a pay as you go plan. Unfortunately you do need a credit card as they only accept payments through Stripe. Which for me is disappointing because I would definitely subscribe to a plan if I could use PayPal.

Riverside

Riverside is actually a complete browser based studio for professional podcast and video recording which you can try for free. Alongside that Riverside has a host of free and paid tools including their transcription service (which is free).

You don't need an account for their transcription service, just drag'n'drop an audio or video file onto the browser window and you're away. Text can be downloaded as a transcript or caption text file. 

Note that if you're using a browser other than Chrome or Edge you may find this doesn't work. I've been trialing Opera's Browser and the transcript tool wouldn't go past the choose file section. Chrome worked just fine though.

Well worth checking out some of their other free tools which include things like a YouTube Channel Name generator.

Descript

The Descript Editor
The Descript Editor can edit video
direct from your script.
Descript
is also an all in one video creation tool that is browser based but also has a desktop version. Their studio uses a fairly unique concept of editing video based on your text script.

Some of Descript's features include cleaning your audio, removing filler words, and you can clone your own voice and have it speak new dialogue. There's also natural speaking AI voices you can utilize.

Since Descript's video editor relies on a text based script it goes without saying that it can also transcribe your audio and video. Not only that, if you already have a transcription, they can sync it to your media word for word.

Descript is well worth a look since there is a free plan that gives you most features with the ability to create up to an hour of video per month.

AI-coustics

AI-coustics is a fairly basic, browser based, AI audio cleaner if you just need to knock out some background noise from your recordings. Clean up to an hour of audio per month on the free account. Test the service out before you sign up in their Playground area.

The Levelator (Bonus Non-AI Free Software)

Not really an audio cleaning tool but more of an audio enhancing tool for podcasters and video creators too. The Levelator is free software for Mac or Windows that simply takes your voice audio and adjusts the speaking level of all voices to one consistent level.

Pretty much does the job of a compressor filter but the authors say it does more than that, evening out all the voices so none sound too quiet and hard to hear.

The software is quite old now but still does the job. Great if you just need something simple to even out your audio and don't really understand the technicalities of using a compressor filter in your video/audio editing software.

Inochi2D - Free Open Source 2D VTuber Avatar Rigging and Puppeteering Software (Part 1)

Inochi2D Creator - Free Open Source VTuber Software. If you've been looking for a way to live perform as a 2D cartoon avatar on camera, whether it be for a live stream or for pre-recorded content like educational videos, then VTuber software is a low cost (or even no cost) option worth looking into. In my previous post, How to Become a VTuber - 2D and 3D Software for Creating and Controlling Your Avatar , I took a brief look at the relatively new but completely free and open source Inochi2D  which I thought showed great potential for my own needs of creating a live performance character rig for my own TET Avatar that I use for all my promotional materials. While it is possible to live perform my character using Cartoon Animator itself, Reallusion's MotionLive2D capture system isn't great - with lip sync in particular. More importantly though, I can't exactly teach people how to use Cartoon Animator if I'm using Cartoon Animator to control my Avatar. What is Inochi2D

Dollars Mocap: Full Body Webcam Motion Capture (Including Hands and Fingers) For iClone and Cartoon Animator

Even though I should be further away from the camera Dollars Mocap MONO still does a good job of  tracking my arms, hands and fingers. Ever since I wrote my series on becoming a VTuber , discovering it was possible to do full body motion capture, including hands and fingers, with just software and a webcam, I've been on the look out for any motion capture software that can bring that functionality to Cartoon Animator. Dollars Mocap is a low cost motion capture application with a free trial that I learned about through the YouTube Channel Digital Puppets  and their test video . It can record full body, upper body, arms and hands, and facial mocap from a live video source or pre-recorded video. Investigating further, I discovered not only does Dollars Mocap have a free iClone7, iClone8 character profile file download (look for it at the bottom of the main program download page), so you can use the saved motions with iClone8, they've also got a demo video for how to convert your

Prome AI Sketch Render Tool - Your Tradigital Clean Up and Colorist Artist for Character and Background Design

Random character head, Biro sketches drawn by TET (left). Render by PromeAI (right) using Prome's Sketch Render tool set to 'Comon:Cartoon, Render Mode: Outline'. W hile I don't do New Year Resolutions, one of my plans for the year ahead is to do more of my own art. Specifically character design drawn in an actual, physical sketchbook.  To that end, I have been spending the last half hour of most days drawing a page or two of random biro sketches in my sketchbook and posting the pages to my Instagram account  (this link will take you to one of my posts). These sketches are mostly practicing my skills because I don't really draw regularly anymore. Here is a tip, if you do this kind of sketching, and push yourself to keep doing it, you will see many drawings that could be taken further, even if you don't have anything they're suited for just at the moment. Which is where my second favorite AI Image Tool (after Leonardo.ai )  PromeAI comes into play. PromeAI

Moho 14 Released - Still the Best 2D Animation Software for Indy Animators on a Budget

Moho 14 Released. Regular readers know I am a Reallusion, Cartoon Animator advocate through and through. Hands down I would recommend Cartoon Animator 5 first over Lost Marble's Moho 14 to anyone who is just starting in 2D animation, is a team of one, or just needs to animate as quickly as possible. However, feature for feature, Moho is, arguably, the best 2D animation software for the rest of us who can't justify a Toon Boom Harmony , or Adobe Creative Cloud subscription (and even with their applications Moho is very competitive on features). You can get started with Moho Debut for just USD$59.99 which is a cut down version of Moho Pro but it still has the most essential features needed for 2D animation. While Moho Pro is a whopping USD$399.99 (Cartoon Animator, which only has one version, is just USD$149.00) upgrades to new version numbers come down to a quarter of the price at USD$99.00. Even though Reallusion just released features like Motion Pilot Puppet Animation and

Start Your 2D Animation Side Hustle - Sell Your Cartoon Animator Characters, Props, Scenes, and Motion Files in the Reallusion 2D/3D Marketplace

Have you thought about starting a side hustle selling your original Cartoon Animator assets in the Reallusion 2D/3D Marketplace ? In this article, the first in a series on selling in the marketplace, I'll give you an overview of what's involved, why you should give it some thought, and whether you can earn enough to quit your day job (or at least have a worthwhile side hustle). If you're an artist with any kind of drawing skills, and you're creating your own original characters, props, scenes, and even motion files for your Cartoon Animator projects, then setting up your own store in the Reallusion Marketplace should be a no brainer. You're making content already, it doesn't cost you anything to set up, and Reallusion only takes a 30% commission from each item sold. (If you think that's a lot, I'll address that further down). Don't be put off if you think your art skills aren't up to professional standards. There are plenty of artists with naïve

Wonder Unit Storyboarder - Free Storyboarding Software for People Who Can (or Can't) Draw

Wonder Unit Storyboarder.  As an independent and solo animator I'm always tempted to try and skip storyboarding my animated shorts because they're usually only single scene sketch comedy type jokes. As a result I have many unfinished projects that kind of petered out due to having no clear finishing line. Storyboarding your productions, no matter how small, gives you a step by step guide of every shot that needs to be completed (no planning shots as you animate). It also allows you to create an animatic that gives you a rough preview of the finished production. In short, you shouldn't skip storyboards as they, generally, increase the chance of the project being completed. Disclaimer - I'm Not a Fan of Storyboarder Upfront, Wonder Unit's Storyboarder  is not my preferred storyboarding software. However it's completely free, has a number of very compelling featu

Can't Draw Characters? Create Highly Detailed Characters from Simple Drawings and Prompts Free with Realtime Canvas by Leonardo.AI

Leonardo.ai's   Realtime Canvas. Create highly detailed images from simple drawings. I f you've had an idea for a character but don't have the artistic skill to design it yourself, or the budget to hire someone to do the design work for you, then Leonardo.ai's Realtime Canvas may be your new creative partner. Sure you could use Leonardo.ai's regular text prompt to image generator but that can be very hit and miss, and may take many generations before you finally craft a complex prompt that's getting something close to what you had in mind. Realtime Canvas, on the other hand, lets you craft a simple text prompt and draw a rough image, both of which you can keep refining until you get a final, real time, updated image that looks close to (and probably better than) what you had in mind.
