From episode to audiogram in four steps
Step 1 of 4
Upload the episode
Drop the audio file in the upload window and pick the spoken language. An audio-only file opens with the Studio template: your cover art, the episode title, live bars, a progress bar and captions.
Step 2 of 4
Check the words
The captions come from the transcript. Correct a name or a misheard word in the editor and the caption changes with it. Lines are broken and timed to reading-speed rules, so nobody has to pause the clip to read it.
Step 3 of 4
Pick a template and a shape
In the Style tab, pick one of 11 podcast templates. Each card previews your own episode. Set your colours, fonts, logo and visualiser style once in the Brand kit; they carry over when you switch between the new templates.
Step 4 of 4
Choose the moments and render
In the Highlights tab, let AI suggest the moments that stand on their own, or mark your own. Tick the ones you want and export them as clips, or export the whole episode. Each one renders as an MP4 with the captions burned in.
What you can change
- 11 podcast templates
- Studio, Spotlight, Vertical Clip, Night Wave, Broadcast and Editorial each have their own look, motion and aspect ratio, and most include a progress bar. Audiogram, Gradient Audiogram, Modern Podcast, Minimalist Audio and Clear Parallax are there too.
- Every social format
- 9:16 (1080×1920) for Reels, TikTok and Shorts. 1:1 (1080×1080) and 4:5 (1080×1350, the Editorial template) for feeds. 16:9 (1920×1080) for YouTube. 3:4 (1080×1440) for portrait.
- Captions that follow the voice
- Show the current line, all lines, or one word at a time. Turn on "Highlight words as they are spoken" to light up each word as it is said, with an optional smooth transition and enter and exit motion.
- Five visualiser styles
- Bars, Wave, Line, Dots or Ring, drawn from the episode audio and evened out per file, so quiet and loud shows both move. Set the accent colour and the sensitivity in the waveform settings.
- A brand kit
- Five colours, a heading font, a caption font and your logo or cover art, set once. Switch to another of the new templates and your brand comes with you, without losing the contrast between captions and their background.
- AI-picked clips
- AI reads the transcript and proposes highlights, each with a start, an end, a title and a description you can reuse for the post. Edit them, add your own, and render only the ones you tick.
- Everything else from the same upload
- The same project gives you a transcript with speakers as DOCX or PDF, AI chapters as CSV or JSON, SRT and WebVTT files for YouTube and podcast apps, and translations into 60+ languages.
Why the captions matter more than the waveform
Most people scroll social feeds with the sound off. In an audiogram the captions do the talking, and a misheard name or a wrong word ends up in front of everyone who sees the clip.
Subtitle AI is a subtitle editor first. Every caption comes from a transcript you can correct, broken into readable lines and checked for reading speed. Fix a word once and it is fixed in the audiogram, the transcript, the SRT file and every clip.
Common questions
What is a podcast audiogram?
- A short video made from podcast audio: a still image or cover art, an animated waveform that moves with the voice, and captions. Podcasters post them on Instagram, TikTok, YouTube Shorts and LinkedIn to promote an episode, because social platforms play video, not audio.
How do I make an audiogram from a podcast episode?
- Upload the episode to Subtitle AI. It transcribes the audio and opens the project as an audiogram. Pick a template and format in the Style tab, choose the moments in the Highlights tab, then export them as clips. Each clip renders as an MP4 with captions.
Which audio files can I use?
- MP3, WAV, M4A and AAC files open as an audiogram automatically, on the Studio template. The free plan takes files up to 30 minutes and 200 MB; paid plans take longer files, up to 5 hours.
What size should a podcast audiogram be?
- Use 9:16 (1080×1920) for Instagram Reels, TikTok and YouTube Shorts, 1:1 (1080×1080) or 4:5 (1080×1350) for Instagram and LinkedIn feeds, and 16:9 (1920×1080) for YouTube. Subtitle AI also offers 3:4.
Can I make several short clips from one episode?
- Yes. In the Highlights tab, AI proposes moments from the transcript, or you add your own with New Highlight. Tick the ones you want and export them as clips. Each one becomes its own MP4.
Can the captions highlight each word as it is spoken?
- Yes. Turn on "Highlight words as they are spoken" in the caption settings, or show one word at a time.
Can I choose a different waveform style?
- Yes. Pick Bars, Wave, Line, Dots or Ring in the waveform settings or the Brand kit, then set the accent colour and how strongly it reacts. Move or resize the visualiser layer to place it anywhere in the frame.
Is there a watermark?
- On free accounts, rendered videos carry a small subtitle.ai mark in the corner until you make any purchase. The smallest credit top-up is €5. Paid plans render without the mark. Subtitle files such as SRT never carry one.
How much does it cost?
- New accounts get €3 of free credits with no credit card. Transcription and rendering use credits, and the export window shows what a render costs before you start it. Short clips cost less than a full episode.
Do I need a video recording of the podcast?
- No. An audio file is enough: the template supplies the picture. If you do have video, upload that instead and the clips show the speakers.
