Free audio waveform video maker

How it works

How to make an audio waveform video.

Four steps, about a minute, and nothing to install.

  1. 1

    Add your audio

    Choose an MP3, WAV, M4A or other audio file up to 10 minutes long. It's read in your browser and never uploaded. Until you add one, a 10-second sample shows how it moves.

  2. 2

    Pick a style

    Bars, Wave or Radial. Set how many bars there are and how thick, and how strongly and how smoothly they react to the sound.

  3. 3

    Add your words and a look

    Type a title and a subtitle, such as the episode and the show, and choose whether to show the progress bar and time. Then pick a look and a frame shape.

  4. 4

    Download the MP4

    Press Download. Every frame is drawn in your browser at 1080p and your sound is added to the file, so it's ready to post. No account, no watermark.

When an audio waveform video isn’t enough

The free audio waveform video is the starting point.

Here you get a waveform, a title and a progress bar over your sound. In Rescroll you describe the graphics you want on your video podcast, such as “show each guest's name and role as I introduce them, in our show colors”, and they're designed from scratch on your own video, placed around you and timed to the exact word you say. Attach your logo or a screenshot of your style, and ask in the chat for any change.

The basics

What is an audio waveform video?

An audio waveform video is a video made from a sound file, with a waveform or a row of bars that moves along with the audio so there's something to watch while it plays. Podcasters use them to post clips, musicians to share a track, and anyone with a voice note to put it where only video is allowed.

This maker reads your file in your browser and measures its frequencies 60 times a second, from the bass to the treble. Bars draws them as a mirrored row with the bass in the middle, Wave as a smooth layered line, and Radial as a ring of bars around a disc. The video runs as long as your file, up to 10 minutes, and the MP4 carries your sound.

If the bars barely move, the recording is quiet: raise Sensitivity. If they sit at the top, lower it. Smoothing sets how slowly a bar falls back after a sound, so a low value suits fast music and a higher one gives speech a calmer, rounder movement.

Questions

Audio waveform video: your questions, answered.

How do I make an audio waveform video?

Add your audio file at the top of this page, pick Bars, Wave or Radial, type a title and press Download. You get a 1080p MP4 of the waveform moving to your sound, with the sound in it, made in your browser with no sign-up and no watermark.

What audio files can I use?

Any audio file your browser can decode, such as MP3, WAV and M4A, up to 10 minutes long. If a file won't open, the page tells you; saving it as MP3 or WAV usually fixes that.

Does the video include my audio?

Yes. The MP4 carries your sound alongside the picture, the same length as the video, so it's ready to post as it is. The sound is encoded as AAC where your browser can do that; if a browser can't encode audio at all, the download has the picture only, and a current version of Chrome will include it. Before you add a file, the page plays a 10-second sample with no sound so you can try the settings.

Can I hear the audio in the preview?

Yes. Once you've chosen a file, a speaker button appears beside the preview's play button. It starts off, so the page stays quiet; press it and your audio plays in step with the picture.

Does my audio file leave my device?

No. The file is read and decoded by your browser on your own device, and the video is encoded there too. It's never sent to a server.

How long can the audio be?

Up to 10 minutes, and the video runs as long as the file. For a short clip from a longer recording, trim the audio to the part you want first, then add it here.

Is the waveform real, or just an animation?

It's real. The bars are measured from your audio: every frame looks at the frequencies playing at that moment, so a kick drum lifts the bass and a voice lights up the middle of the range. Only the sample shown before you add a file is made up.

Can I make a circular audio visualizer?

Yes. Choose Radial under Style for a ring of bars around a disc. With the progress bar on, the disc shows the time and the progress runs round its rim; with it off, the disc becomes a record whose center beats with the bass.

How many bars can the waveform have?

From 16 to 96, in steps of 4, in Thin, Regular or Bold. Fewer, bolder bars read well on a phone; more, thinner bars look finer on a large screen.

Why do the bars barely move?

The recording is probably quiet. Raise Sensitivity and the bars reach further for the same sound. If they sit at the top all the time, lower it.

Is the audio waveform video maker free?

Yes. It's free to use and free to download, with no account, no email address and no watermark on the video. There's no limit on how many you make.

What format and resolution is the video?

An MP4 with H.264 video, at 1080p in the shape you choose: 1080×1920 (9:16) for TikTok, Reels and Shorts, 1920×1080 (16:9) for YouTube, 1080×1080 (1:1), or 1080×1350 (4:5) for the Instagram feed. You can export at 30 or 60 frames per second.

Is my video uploaded anywhere?

No. The audio waveform video is drawn and encoded on your own device, using your browser's built-in video encoder. Nothing is sent to a server and there's no render queue.

Which browsers does it work in?

It needs a browser that can encode video with the WebCodecs API: current versions of Chrome, Edge and Safari, and Firefox on a computer. If your browser can't, the page tells you before you start.

Can I use the audio waveform video in client work, ads or monetized videos?

Yes. The video you download is yours to use in personal and commercial projects, with no attribution needed.

Can I match my brand, add my logo or change the design?

Not in the free maker, which is deliberately simple. That's what Rescroll's AI motion graphics are for: describe the graphic you want in plain English, attach your logo, fonts or a screenshot of your style, and it's designed from scratch on your own video, placed around you and timed to the word you say. Ask for any change in the chat. It's part of the Pro, Ultimate and Scale plans.
