What is Audio Studio?
Audio Studio is a browser-based workspace for turning spoken audio into text you can actually use — an accurate transcript, synchronized captions, and, if you need it, a polished captioned video, all without uploading your recording to a storage service or account. It's built around one core idea: audio is easier to search, edit, share, and repurpose once it's text.
What can Audio Studio do?
- Transcribe — upload an audio file and get an accurate, timestamped transcript of what was said.
- Edit the transcript — click any line to correct it, merge adjoining lines, delete lines, or search across the whole thing.
- Generate captions — download the transcript as SRT or WebVTT, the two subtitle formats supported by virtually every video platform and player.
- Create a captioned video — turn the audio, a waveform visualization, and your captions into a downloadable MP4.
- Export the transcript — plain text, ready to paste anywhere or hand off to another Convertam tool.
Audio transcription explained
When you click Transcribe, Audio Studio sends a compressed copy of your audio to Convertam's AI provider, which listens to it and returns exactly what was said, broken into timestamped segments. This version transcribes clips up to 3 minutes — a real, current limit driven by how much audio can fit in a single request, documented plainly below rather than hidden. Nothing is invented: silent or unintelligible stretches are left out or marked, never filled in with guessed words.
How audio becomes a transcript
Underneath, the flow is: your file is read and its waveform is drawn locally in your browser → when you transcribe, a compressed copy of the audio is sent for AI transcription → the result comes back as timestamped segments you can click to jump to that point in the audio → editing a segment's text never touches the original file, only the transcript.
Creating captions from audio
Once you have a transcript, Download SRT and Download VTT generate real subtitle files — properly formatted timestamps, line-split for readability — ready to attach to a video in any editor, or to upload alongside your audio wherever captions are accepted.
Turning audio into a captioned video
Many platforms (social feeds especially) don't support audio-only posts, or perform far better with video. Create Captioned Video renders your audio against a clean branded background with a waveform visualization and your captions burned directly into the frame — a real MP4 you can post anywhere a plain audio file wouldn't work.
Audiograms explained
An audiogram is exactly this kind of audio-plus-waveform-plus-captions video — a format that's become the standard way podcasts, sermons, and interviews get shared as short, captioned clips on social media. Audio Studio's captioned-video export produces one directly from your transcript, no separate editing software required.
Common use cases
- Meetings — turn a recorded meeting into a searchable, shareable transcript.
- Interviews — transcribe an interview for quoting or editing.
- Lectures — generate a transcript students can search and review.
- Sermons — create captioned video clips for social sharing.
- Podcasts — produce audiogram clips to promote an episode.
- Voice notes — turn a quick recording into text.
- Content creation — get accurate captions for accessibility and reach.
- Announcements — turn a short recorded announcement into a shareable video.
Supported formats
MP3, WAV, M4A, AAC, OGG, and WebM — any format your browser can natively decode audio from.
Privacy and temporary processing
Playback, the waveform, and video rendering all happen locally in your browser — your audio file itself is never uploaded for those steps. Transcription is the one exception: a compressed copy of the audio is sent to our AI provider to generate the transcript, processed for that single request, and not stored afterward. Convertam is designed for processing, not permanent media storage.
Limitations
- Transcription length: clips up to 3 minutes in this version — a real technical limit, not an arbitrary one, driven by how much audio fits in a single AI request.
- Languages: transcription quality depends on how well the underlying AI model handles the spoken language; results are most reliable for widely-spoken languages.
- Speaker labels: not supported in this version — Audio Studio doesn't attempt to guess who is speaking when, since that would risk showing you a confident-looking but wrong answer.
- Word-level timing: captions are timed per sentence/clause, not per individual word, in this version.
- Video creation: one background style, one caption look, and a single square (1:1) aspect ratio in this version — additional customization is planned.
