Interview-style shows and podcasts with 2+ speakers are incredibly popular. That’s why we’ve built Resound to be able to edit multitrack episodes while keeping everyone’s audio in sync.

What is Multitrack Editing?

Multitrack editing allows you to upload up to 4 tracks into Resound, detects filler sounds (umms and ahhs) and silences in both tracks, mix and master audio with AI, and apply edits to multiple tracks while keeping them in sync.

How multitrack editing works (step-by-step)

1. Open Resound

2. Select Upload a File

3. Locate the files you want to process on your computer

  • Select the top file

  • Hold down the shift key

  • Select the other files you wish to include

  • Select Open

4. Process audio

Click "Process audio" and confirm that you wish to proceed when the popup appears telling you how much time will be deducted from your usage meter. Processing begins the process of detecting filler sounds and long silences in your audio.

5. Switch between speaker views (optional)

You can switch between All Speaker track view or Individual audio track view on multitrack episodes. All Speaker track view is shown by default but you can toggle your view by opening the Track section in the sidebar. Edits made on single-track view will be applied to both tracks so that tracks are kept in sync.

6. Cut, keep, or adjust your edits

  • All tracks are displayed as one waveform on the frontend, for simplicity.

    Behind the scenes, each track is edited separately.

  • We detect edits and highlight them in blue

  • Click and drag an edit's boundaries to make fine-tuned adjustments

  • Edits you cut are red, edits you keep are green, and unreviewed edits are blue.

  • Use keyboard shortcuts to work faster

  • Behind the scenes, Resound will make sure everything stays in sync between all tracks as you edit. If we detect an umm in track 1, for example, we'll also remove that same region from all other tracks to ensure everything stays aligned.

7. Export your edited audio 🎉

After reviewing your edits, you can export a WAV, MP3, or AAF of the tracks merged together, or click "export individual tracks" to get all the individual tracks and a merged track.

FAQs

What files will I get when I export a multitrack episode?

Resound exports a merged version of multitrack projects by default. But if you want individual tracks you can select "Include Individual Tracks". If you choose to get individual tracks ou will get an individual copy of each track you uploaded in each of the file formats you select, AND a merged version as well.

For example, If you upload 2 files and export a WAV and MP3 with "include individual tracks" selected, you will get 6 files (2 individual WAVs, 2 individual MP3s, 1 merged WAV, and 1 merged MP3).

I only see one waveform, do you edit my tracks separately still?

Resound defaults to showing all tracks combined on the front end, but behind the scenes, your individual files are being kept separate and edited individually. You can switch between track views on multitrack episodes. You will see all tracks as one as the default view and can toggle to an individual track and make edits. Edits made on single-track view will be applied to both tracks so that tracks are kept in sync.

How many files can I upload and edit simultaneously?

You can upload up to 4 tracks for editing in sync simultaneously. If you need to do more than that, simply merge those tracks together in your DAW, then import them as a single track (or groups of tracks) into Resound.
