Audio to Video: Free Audiogram Maker | audiogram.video

# audiogram.video > Turn a podcast clip, voice note or song into a video with a moving waveform, cover art and word-by-word captions. Free, no watermark, made in your browser. audiogram.video is a studio that runs in the browser: it reads a recording from the visitor’s device, draws every frame of the video there and encodes the MP4 locally, so the recording, cover art and photos are never uploaded. The one exception is captions from speech, which start automatically when a recording is added (the start card’s Automatic captions switch, on by default, turns this off): only the chosen clip’s sound, mixed to mono and compressed, is sent to a speech-recognition provider to be written out word by word, and nothing is kept. There is no API and no account. The examples on the site are short clips (under a minute) from real podcasts that are in the public domain (US federal government productions) or licensed CC BY / CC BY-SA, credited on the Credits page; visitors can open any of them in the studio to try it without a file of their own. ## Tool and guides - [Audio to video: free audiogram maker](https://audiogram.video/): The studio: templates, moving waves, cover art, captions and MP4 export, with a how-to. - [Convert MP3 to MP4 with an image](https://audiogram.video/mp3-to-mp4): Give an MP3 a picture and save it as an H.264 MP4 at 720p or 1080p. - [Music visualizer maker](https://audiogram.video/music-visualizer): Spectrum bars, rings and spinning records that move with a song, saved as MP4. - [Podcast audiogram maker](https://audiogram.video/podcast-audiogram): Square episode promos with cover art, captions and a saved style for your show. - [Add music to a photo](https://audiogram.video/add-music-to-photo): Put a song behind a single photo and save it as a video for posts and messages. - [Convert M4A or a voice memo to MP4](https://audiogram.video/m4a-to-mp4): Voice memos and other M4A files to video, with captions and a waveform. - [Convert WAV to MP4](htt
