WMA to SRT in Your Browser
SubTran converts WMA to SRT using local audio extraction and OpenAI Whisper word timestamps, then presents editable SubRip cues you can review and download.
how to convert WMA to SRT
Upload a WMA file, choose automatic language detection or pick the spoken language, then transcribe and edit the SRT preview before downloading.
Upload WMA file
Select a WMA from your device or Microsoft media libraries; the browser reads the file with FFmpeg WebAssembly.
Transcribe with word timestamps
SubTran compresses audio locally, sends chunks to OpenAI Whisper for speech-to-text, and receives word-level timestamps for precise timing.
Edit and download SRT
Adjust sequence numbers, timestamps, line breaks, and cue text in the editable SubRip preview, then export SRT, VTT, or TXT for editors and players.
WMA subtitle converter features
Automatic speech transcription
OpenAI Whisper recognizes dialogue and returns word timestamps used to build synchronized SubRip cues for accurate SRT timing.
Local audio extraction
The browser extracts and compresses the audio track locally using FFmpeg WebAssembly before sending transcription chunks to the service.
Readable SRT segmentation
Words are grouped by punctuation, pauses, cue duration, and line length so cues are readable in editors and players, not fixed intervals.
Editable SRT preview
Review and edit sequence numbers, start and end timestamps, cue text, and line breaks before exporting SubRip files for caption editors.
Long recording support
Long WMA recordings are split into ten minute chunks, transcribed sequentially, and merged to a continuous timeline in the final SRT.
Multiple spoken languages
Use automatic language detection or pick the language beforehand to improve transcription accuracy for multilingual archives.
audio to SRT from WMA benefits
Skip manual timestamps
Start with synchronized cues built from word timestamps so you do not type dialogue and timing for every line by hand.
Keep video frames local
When converting video, only compressed audio chunks leave your device, so video frames and visual content remain on the machine.
Import into common tools
Export standard SubRip SRT files that import into video editors, caption editors, media players, course platforms, and publishing workflows.
Improve accessibility
Generate readable captions that help viewers follow speech, improving comprehension for learners and accessibility for all audiences.
Create reusable text
Download the same transcription as TXT or WebVTT when you need plain text or alternative caption formats for indexing and search.
Work in a browser
No desktop software required: extract, transcribe, edit, and download SRT entirely in the browser for Windows recordings and legacy WMA files.

can I extract subtitles from a WMA file
How do I convert WMA to SRT online?
Upload the WMA file to SubTran, choose automatic detection or set the spoken language, start transcription, then review and download the SRT preview. The process uses browser audio extraction, OpenAI Whisper, and an editable SubRip editor.
Does the SRT include timestamps?
Yes. Whisper returns word-level timestamps that SubTran converts into numbered SubRip cues with start and end times suitable for editors and players.
Can I edit the generated subtitles and word timestamps?
Yes. The SRT preview is fully editable: you can change cue text, adjust start and end times, edit sequence numbers, and set line breaks before export.
What happens with long recordings and how are they merged?
Long WMA files are split into ten minute audio chunks in the browser, transcribed in order, and timestamps are offset so the final SRT is one continuous timeline.
Can I also download TXT or VTT versions?
Yes. The same transcription result can be previewed, edited, and exported as SubRip SRT, WebVTT, or plain TXT for different workflows.
Is audio processed locally in the browser when converting WMA?
Yes. SubTran extracts and compresses the audio locally using browser APIs, so video frames and original files remain on your device while only audio chunks are sent for transcription.
How to group words into readable SRT cues rather than fixed intervals?
SubTran groups words around punctuation, pauses, cue duration, and line length so cues read naturally in caption editors and media players instead of using arbitrary fixed windows.
Can I batch convert multiple WMA files to SRT?
SubTran processes each WMA as a separate job; you can queue several files in sequence, but ensure each file uploads and finishes transcription before exporting its SRT.
