Audio to SRT

Use audio-to-SRT when you have a narration, interview or lesson recording that needs timed captions. AudText uses transcription timestamps to create subtitle cues; it also keeps a plain transcript available for notes and document exports. The upload limit is 100 MB, and no account is required.

From a recording to timed subtitle cues

Upload a supported recording such as MP3, WAV, M4A or FLAC. Select the spoken language if it is offered, or choose automatic detection. After processing, click a word in the synchronized transcript to replay that point, then choose Download SRT. Keep the original recording so you can check uncertain phrases.

How the SRT timestamps are created

Each SRT cue has a sequence number, a start and end time, and its caption text. AudText creates timed cues from the recognized speech. Automatic cue breaks are a first draft: check whether each caption has enough reading time and fits the final media. The timestamps follow the uploaded recording, so later cuts or a new introduction may require adjustments in a subtitle editor.

Review captions in your final video

The caption times refer to the uploaded recording. Adding an intro, trimming the audio or moving the track in a video can make those times differ from the final timeline. Import the SRT into a subtitle or video editor and check synchronization, wording, cue breaks and readability against the finished media. AudText does not provide a cue timing editor.

What the plain text editor changes

Editing the plain transcript or using Find and Replace changes the text used for copying and document downloads. It does not rewrite the generated SRT or VTT captions or retime words. To correct a subtitle, edit the downloaded SRT in a subtitle editor. Silence, background noise and overlapping voices can leave missing or inaccurate words that need manual review.

AUDTEXT SAMPLE

A short recording and its actual SRT export

This synthetic English recording was transcribed with AudText on 12 October 2026. The unedited output below shows how cue numbers and timestamps work. “AudText” was recognized as “odd text”: always review names and timing before publishing.

This is an odd text subtitle example.

FAQ

Frequently asked questions

Which audio files can I convert to SRT?+

AudText accepts MP3, WAV, M4A, FLAC, AAC, OGG, OGA, OPUS, WMA and MPGA audio files, along with supported video formats. Each upload must be a valid recording no larger than 100 MB.

Does editing the transcript also correct the SRT?+

No. The plain text editor changes the copied text and document exports. SRT and VTT downloads retain the generated caption text and timing, so subtitle corrections need to be made in a subtitle editor.

Why are my subtitles out of sync with the video?+

The timestamps match the uploaded recording. If the video has a different start point, an added intro or cuts in the audio, adjust the captions in your video or subtitle editor to match the final timeline.

Can I turn silence or music into subtitles?+

The converter is designed to transcribe speech. A recording with no recognizable speech may produce little or no text. Detected sound events are not a substitute for manually reviewing captions for the final media.

Is SRT export available without registration?+

Yes. You can upload a supported recording and download its available SRT result without an account or a separate export charge. Timed subtitle export requires timestamp data in the transcription result.

Is AudText really free?+

Yes. You can transcribe and download results without a subscription or account.

Which files can I upload?+

MP3, WAV, M4A, MP4, FLAC, AAC, OGG, OGA, OPUS, WebM, WMA, AVI, MKV, MOV, MPEG and MPGA are accepted up to 100 MB.

Which languages are supported?+

Automatic detection covers more than 90 languages. English, Spanish, Portuguese, German, French, Russian and Turkish can also be selected manually.

Are speakers and non-speech sounds detected?+

Speaker information is added automatically. Sound events such as laughter or applause may also appear when detected; structured details are included in JSON.

Can I create subtitles?+

Yes. Every result includes both SRT and VTT downloads with timestamps.

How accurate is the transcript?+

Accuracy depends on recording quality, background noise, compression, accents and overlapping speech. Verify important names, numbers and quotations against the recording.
