Use genuine AAC media, not a renamed recording
The direct uploader accepts filenames ending in .aac. Typical inputs include a saved mobile audio recording or exported AAC speech clip. AAC audio can use different profiles; DRM and unsupported codecs will fail. Audio decoding depends on the underlying codec and the recording, not on the extension alone.
What the VTT download contains
The output is a WebVTT caption file based on recognized speech. It is designed for web players and timed browser captions. Vtt is a timed text track, not burned-in video captions. The source recording is not altered by downloading this file.
Review the words before sharing
Listen back to the original AAC recording and inspect proper names, numerical values, jargon and background speech. Automatic segment times and speaker turns may need revision.
Use the same transcript in other formats
One completed transcription can also be downloaded in TXT, DOCX, SRT, VTT and JSON. You do not need to submit the recording five times to obtain different export types.
How to turn AAC speech into VTT
- Choose an authorized .aac audio recording containing audible speech. The quick form displays its file-size limit; larger eligible Premium recordings require the main app's chunked uploader.

Format warning: AAC audio can use different profiles; DRM and unsupported codecs will fail.
Export detail: VTT is a timed text track, not burned-in video captions. A recording without understandable speech cannot yield meaningful transcript text.
Free account: 60 transcription minutes across 20 jobs per month, subject to per-job, file-size and source restrictions. Trying without an account can return a shortened preview instead of a full downloadable job.
Browse all supported input/output formats. For large recordings, go through the main uploader; you can select the same export format after processing.
Frequently asked questions
Can I upload a file in AAC format and download VTT?
Yes, if the .aac audio recording is decodable and contains understandable speech, and the job completes within your limits. Afterward, open Download on the completed job and select VTT.
Does AAC to VTT change the original media?
No. The output is a WebVTT caption file generated from spoken words; it is not a byte-for-byte media format conversion.
Why might an upload of AAC fail?
AAC audio can use different profiles; DRM and unsupported codecs will fail. The recording can also exceed the upload, duration or account limits. Try a small unprotected file first.
Can I get VTT for free?
An account includes 60 minutes and 20 jobs per month, with source/file restrictions. An anonymous try can be preview-only; do not assume every export is available without a completed job.
Can I also export my AAC transcript as another format?
Yes. The same completed job has TXT, DOCX, SRT, VTT and JSON download options, subject to normal access restrictions.
