Free, no watermark." url: https://audiogram.video/audio-waveform-visualizer --- Free · no watermark · in your browser # Audio waveform visualizer Open a voice recording and watch its waveform move as a line, bars, dots or a ring. Pick a style, set the colours and export a waveform video. An audio waveform visualizer draws a recording as a shape that moves with the sound, so people can see a voice even with the volume off. Open a recording above and the studio animates it as a wide wave with your title, then lets you switch between nine styles in the **Wave** panel. This page is about speech: interviews, voice notes, narration and podcast clips, where the wave should feel calm and follow the rhythm of talking. For songs, where you want bars jumping to the bass and treble, the [music visualizer](https://audiogram.video/music-visualizer) starts from a style built for that. The animation and the export happen in your browser, and the video carries no watermark. ## How to make a waveform video 1. ### Open the recording **Square** is selected on the card; choose **Vertical** or **Landscape** if you prefer. Press **Choose audio** (Ctrl+O or ⌘+O) or drop an MP3, WAV, M4A or other file on the card. 2. ### Pick a wave style The **Wave** panel opens first. Try **Wave**, **Mirror**, **Bars**, **Scope**, **Seek bar**, **Dots**, **Ring** and **Pulse** while the preview plays (Space). 3. ### Shape it Use **Size** to fill more or less of the frame, **Sensitivity** to make it move more or less, and **Detail** for the number of points or bars. In **Style**, set the **Wave** colour and the **Background**. 4. ### Add words if you want them In **Text**, add a **Title**. In **Captions**, **Make captions** writes out the clip’s speech (its sound is sent to our speech provider for that), or set the caption style to **Off** for a wave on its own. 5. ### Export the animation Press **Export**, choose **60 fps** for the smoothest movement, then **Export video** and **Download video**. ## Nine waveform styles, and when each works * **Wave:** one smooth, flowing shape. The friendliest choice for a single voice. * **Mirror:** the same shape reflected above and below a centre line, the look most people picture when they hear “sound wave”. * **Bars:** a row of bars that follow the frequencies in the sound. Livelier, closer to an equaliser. * **Scope:** the actual waveform drawn like an oscilloscope trace. Every syllable shows; it suits tech and science content. * **Seek bar:** the whole clip’s waveform laid out once and filled in as it plays, like a voice message in a chat app. * **Dots:** a few round dots that bounce with the voice, like a typing indicator. * **Ring** and **Pulse:** circular shapes that grow from the centre, good around a round photo or logo. * **None:** no wave, for when only the words or a picture should show. A short test helps: play the busiest five seconds with **Space** and switch styles while it plays. Whichever still reads clearly at phone size is the right one. ## Getting the movement right for a voice ### Sensitivity Speech has big gaps between loud and quiet. If the wave barely moves, raise **Sensitivity**. If it slams to the edges on every word, lower it. For the sound itself, **Even out the volume** in the **Audio** panel lifts a quiet or uneven recording to a steady level, so listeners don’t have to reach for the volume. ### Detail **Detail** sets how many points, bars or dots make up the shape. Low values give a bold, graphic look that survives being shrunk in a feed. High values look precise on a big screen but turn to fuzz on a phone. ### Colour and contrast The **Wave** colour in **Style** should stand out from the background as clearly as text does. A pale wave on a dark gradient, or a dark line on the off-white **Paper** template, reads at any size. With **Cover art** added, the wave picks up one of its colours automatically. ## Templates where the waveform is the star The page opens on **Studio wave**, a wide smooth wave with the title above it and no artwork needed. Others in **Templates** put the wave at the centre too: * **Terminal:** a green scope line on black with monospace type. * **Paper:** a fine dark line on warm off-white with a serif title. * **Pulse:** rings that breathe with the voice in bright colours. * **Voice note:** bouncing dots and big captions, for quick vertical posts. For podcast promos with cover art and captions, the [podcast audiogram maker](https://audiogram.video/podcast-audiogram) starts from a design built for shows. ## Waveform videos: questions and answers ### What is an audio waveform? It is a picture of a sound over time: the height shows how loud it is at each moment. Animated, it moves as the sound plays, which is why it is used to show that a video has speech or music in it. ### Can I export just the waveform on a plain background? Yes. Leave out the cover art, set **Background** to **Solid** under **Style**, clear the title and set the caption style to **Off**. The video then shows only the moving wave. ### Can I get a transparent background to use in an editor? No. The export is an MP4, which has no transparency. A solid black or green background can be keyed out in most editors, or you can build a waveform inside the editor itself. ### Why does my waveform hardly move? The recording is probably quiet, or the voice sits low in the mix. Raise **Sensitivity** in **Wave**, and try a larger **Size** or a style with fewer, bolder parts, such as **Dots** or **Bars** with a low **Detail**. ### Is the waveform drawn from my real audio? Yes. Every frame is drawn from the sound at that moment of your clip; nothing is a looping animation. **Scope** and **Seek bar** show the waveform itself most literally. ### Does the recording get uploaded? Not to draw or export the wave: that all happens on your device. Only if you press **Make captions** is the selected clip’s sound sent to our speech provider, to write out the words. ## More ways to turn sound into video * [ Free audiogram maker Turn a recording into a video with a moving wave, cover art and captions. ](https://audiogram.video/) * [ Music visualizer maker Spectrum bars, rings and spinning records that move with a song, saved as MP4. ](https://audiogram.video/music-visualizer) * [ Podcast audiogram maker Square episode promos with cover art, captions and a saved style for your show. ](https://audiogram.video/podcast-audiogram) * [ What a visualizer is (and isn’t) Visualizers versus music videos, official visualizers, and when artists use each. ](https://audiogram.video/what-is-a-visualizer) * [ How to make an audiogram Choosing the moment, the design, the captions and the sizes, step by step. ](https://audiogram.video/how-to-make-an-audiogram) * [ Vertical podcast clips with captions Captions-first 9:16 clips from an audio episode, for Reels, TikTok and Shorts. ](https://audiogram.video/podcast-clips)
