WMA audio to text
WMA is the container of the Windows recorder, and the site accepts it: the file goes up unchanged, and the words come back with the second they start and the second they end. One file is up to 64 MB and 120 minutes, the free plan is $0 with 3 files a day, Pro is $10 a month paid yearly.
A Windows file needs no conversion
The upload field of the site names ten containers, and wma is one of them: mp3, wav, m4a, mp4, webm, ogg, flac, aac, wma and mov. A recording saved by a desktop tool as .wma can be dragged into the widget as it is. Nothing is re-encoded on your side, and the service does not ask you to install anything.
What you get is the same for every container: the transcript text, a list of segments with a start and an end time, speaker labels when you ask for them, and the exports.

Speakers in a WMA
Most WMA files in the wild are meetings, interviews and screen recordings with more than one voice. Switch on “Split by speaker” and the transcript is grouped by voice, with a label on every line. How seven services handle the same problem is compared on the speaker labels page, and the meeting guide shows the workflow from the recording to the shared document.
Where the recording is read
Russian audio is processed on our own transcription infrastructure, outside the United States. A file that is entirely in English can be passed to a third-party cloud speech provider in the United States when that fallback is enabled on the server. The audio is used to produce the transcript and to run the service; it is never sold and never used to train models for other customers. On the free plan transcripts are kept for 7 days, and a deleted file leaves the live system immediately and the encrypted backups within 30 days.
Three situations worth preparing for
- The recording is longer than 120 minutes. Split it into parts. The long-recording guide shows how, and how to send the parts from a script.
- The file is over 64 MB. Compress it once, keeping a copy of the original, and upload the smaller one.
- The sound is in another language. Only Russian and English are recognized. A file in any other language comes back empty or nearly so, and we would rather say so than guess.
The other nine containers
The same pipeline reads mp3, wav, m4a, mp4, webm, ogg, flac, aac and mov, so a WMA and an MP3 of the same hour return the same text. The general guide has the full list with the limits next to each one.
Put a file on the page and read the first lines.
The widget below is the same one as on the home page: file → transcript with timecodes and speakers → export. The transcript is saved to your account.

Questions this page answers.
Do I have to install anything for WMA?
No. The service runs in the browser and on the server, and WMA is one of the containers the upload field names, so the file is read without a converter on your side.
What is the largest WMA I can send?
64 MB per file, on every plan. The length limit is separate: 120 minutes of sound on Pro and Team, 30 minutes on the free plan.
Will the speakers be separated in a WMA?
Yes, if you ask for it. Tick “Split by speaker” and each line is marked with the voice it belongs to, on every plan including the free one.
Can I send a WMA through the API?
Yes. The REST endpoint takes a multipart file, the same one the widget uses, and the MCP server and the plugins for Claude and ChatGPT call it under the hood.
What happens to the recording after the transcription?
It stays in your account until you delete it. The audio is never sold and never used to train models for other customers, and a deleted file leaves the live system immediately.
