Resound is the AI editing app for podcasters. Resound exists to automate the tedious parts of podcasting so that you can focus on your message, not your mess-ups. Automatically detect umms and ahhs in your podcast in minutes.

Learn more about Resound

Resound’s machine learning models for filler sound detection are optimized for audio in English. Resound has not been optimized for any other language except for English at this time.

However, many users from around the world have tried Resound and found that it still works on their audio. Users have tried detecting ums and ahs in their audio for Spanish, German, French, Polish, and many other languages. They often report that they are very happy with the results. In other words, if you're not sure that Resound supports your language, just give it a try anyways on our free trial to see how it works.

Resound can also detect silences across all languages and mix and master audio with Enhance regardless of language.

Yes! Resound detects filler sounds like ums and ahs with AI that has been specifically trained to make the most accurate edits. You can review each edit to cut (delete) or keep (leave in). Or you can cut all in one click. We've built this over 4 years and reached an incredibly accurate standard. Learn more here.

Yes! Resound automatically detects long and boring silences when you process audio through the app. You can review each edit to cut (delete) or keep (leave in). Or you can cut all in one click. Learn more here.

Yes, you can easily make your own manual edits in Resound. Just right-click anywhere on the waveform to highlight a section you wish to cut (aka delete).

Yes, you can automatically adjust the volume of your tracks using AI in Resound. Just upload to Resound and click the Enhance icon to normalize the sound of your track or tracks, and mix and master them.

You cannot manually adjust the volume of tracks at this time, but our Enhance feature will do this for you. Learn more in this guide to Enhance.

Yes, you can easily mix and master your audio or video with Resound's AI. Enhance automatically mixes and masters your podcast to sound crisp, clear, and polished before you hit publish. Learn more here.

Unfortunately, you cannot record audio in Resound. We believe in radical focus. And we’re hyper-focused on building the AI audio engineer of the future, not building a recording platform.

If you want to record a solo track, we recommend using Resonate’s free online voice recorder. If you’re recording 2 or more people, we recommend using Riverside.

Resound does not currently offer Transcriptions of audio. Though we may in the future.

No, Resound cannot detect filler words like you know, right, so, and, etc. Resound currently detects filler sounds (um, ah, eh) and silences, but not filler words such as you know, right, so, and, etc. If you want to cut out additional mistakes that Resound did not detect, you can simply right-click on the waveform to add your own edits.

No, Resound cannot mute silence in only one track inside of a multitrack project. Currently, Multitrack editing in Resound applies edits to both tracks, for a simplified workflow that keeps all your edits in sync. For example, if you cut out an umm from track 1 it will also cut out the same timestamp from track 2 (to keep tracks in sync).

Right now the easiest way to share Resound with a collaborator is to share your login information. We do not yet have admin roles and permissions, though we hope to add this in the future.

Note: Never share your password with someone you don't know or trust. Use a secure service like 1password or Proton Pass to share passwords with others in an encrypted way.

Right now Resound cannot replace an edit with silence, though we may add this in the future.

No, Resound currently does not allow you to add intro and outro music to an existing project. However, we're working on adding this feature, so that should be available soon. For right now, your best option will be to add music with a tool like GarageBand, Audacity, or your DAW of choice after you process files through Resound.

No, at this time you cannot merge multiple tracks together.

Resound lets you stack up to 4 separate tracks on top of each other (meaning they both start at the same time) but does not yet support combining multiple tracks linearly (ex: track 1 plays from 1-3 mins, track 2 plays from 3 mins to 40 mins).

No, Resound does not yet offer the ability to rename your files or project. We plan to add this soon but don't currently have the ability to rename projects in Resound.

No. Resound does not yet support 32-bit float files, though we hope to add this in the future.

No, Resound cannot currently export XML video files. We hope to add this feature in the future though! See a full list of accepted file formats here.

Projects in Resound are deleted after 1 day for free users, 15 days for Creator users, 30 days for Professional users, and 60 days for Studio users.

No, right now you cannot rename projects or files within Resound. This is a feature we'd like to add in the future, but do not yet support. Upvote this feature on our public roadmap here.

No, Resound currently does not detect or reduce breaths in audio or video files. However, we do improve the sound quality of your files with our Enhance feature, which uses AI to mix and master your audio. Learn more about Enhance here and upvote this feature request for breath detection/reduction here.

No, currently Resound cannot export shorter clips from a full-length project. If the project in Resound is 10 minutes, Resound will only export the entire project from start to finish. Want us to change that? Request a new feature here.

To upload a file in Resound, follow these steps:

If uploading your audio file to Resound is not working, here’s what you should do:

Processing in Resound can take anywhere from 30 seconds to 15 minutes or more.

This depends primarily on the speed of your internet connection, the size of your files, and the number of files. Because of how subjective this is, it’s hard to give a concrete time that it takes.

As soon as you drop a file into Resound, the app begins a multi-step process of (1) uploading your file, (2) processing it, then (3) creating an editing session for you to review.

Uploading the file takes the longest time, and that is why the main factor that slows down this process is the size of files and your individual internet speed.

If you believe the app is not working (and it’s been more than 10-20 mins with your project) feel free to reach out in the app messenger to get support.

To export audio in Resound, follow these steps:

Resound will export the files you are currently listening to in the app. If the Enhance feature is on, the exported files will be enhanced; if it's off, the exported files will be your original audio files.

Your download will be saved to your computer's Downloads folder automatically.

If exporting your audio from Resound is not working, here’s what you should do:

Exporting can take anywhere from 60 seconds to 15 minutes or more.

This depends primarily on the speed of your internet connection, the size of your file(s), the number of files, and the number of file formats you choose to export.

Because of how subjective this is, it’s hard to give a concrete time that it takes.

As soon as you click “Export” in Resound, the app begins the process of making edits to your audio files, keeping multitrack projects in sync, preparing your file names, and zipping them up into an organized folder.

If you believe the app is not working (and it’s been exporting for more than 30 mins) feel free to reach out in the app messenger to get support.

For uploads, there is no minimum or maximum file length requirement.
​
For processing, there is no minimum length requirement, but there is a maximum. When you process audio through Resound's AI, it counts towards your monthly usage time. That's 20 mins for free plans, 4 hrs for Creator, 10 hrs for Pro, and 30 hours for Studio plans. If your file exceeds the remaining usage time on your account you will be asked to upgrade or wait until your usage time renews.

Sometimes the app appears stuck at 75% while you upload but it is in fact still working on the backend. Please wait at least 15 minutes, as sometimes the upload is slower based on the size of the file, the number of files, and the speed of your internet connection. If you're still having trouble, please try canceling the upload and trying again. If that fails, please submit a ticket in the app through the messenger.

To report a bug or issue, please log in to the app, open the messenger (bottom right corner), and submit a ticket for our team to review.

Resound plans are based around a simple concept of audio processing time. Audio processing time determines the length of audio or video files that you can upload to Resound. Your hours will be renewed at the start of your next billing cycle. This is true for free plans (which get 20 mins per month) and paid plans.

You can see when your plan renews in two places:

Usage time renews at the same time that you signed up for your account or that your billing renews, calculated using the UTC time zone. It's important to note that if you have a failed payment, your usage meter may not be updated.

Resound's core feature is AI filler sound detection and Enhance (ai mixing and mastering). You can use both of these features for a specific time limit each month, which we call usage time, audio processing time, or AI processing time.

Unused processing time does not rollover to the next month. Unused processing time expires and is refilled every month at your billing renewal date.

Resound does not currently offer any Student or Educational discounts for our product. However, we may consider adding this in the future. If you have a unique circumstance that prevents you from paying for Resound, please log into the app and submit a ticket to share more information and request support. Please provide a detailed explanation about your unique situation, how we can help, and any other questions.
