Timed transcript first
SRT quality starts with accurate segment timing and reviewed speech, not simply adding numbers to plain text.
AUDIO SUBTITLE WORKFLOW
Convert audio into timestamped SRT subtitles.
Upload spoken audio, create a transcript with segment timing, review the words and cue boundaries, then export a standard SRT file.
Upload audio for SRT →What this workflow gives you
Cue controls
Adjust maximum cue length and duration so subtitles remain readable at the pace of the recording.
Playback verification
Use timestamps to check names, numbers and cuts against the source before publishing the subtitle file.
How it works
- Upload a supported audio file. Choose MP3, WAV, M4A, FLAC, OGG or another supported recording with audible speech.
- Transcribe and correct the text. Review the automatic draft with playback and check speaker changes or overlapping dialogue.
- Export SRT. Set cue limits, preview the timed output and download the numbered subtitle file.
How an SRT file is structured
SubRip subtitles are a sequence of numbered cues. Each cue contains a start time, an end time and one or more lines of text. The timing uses hours, minutes, seconds and milliseconds. Players use those time ranges to decide when each subtitle appears.
Audio does not contain visual scene changes, so cue breaks must follow speech timing and readability. Avoid extremely long lines, cues that flash too quickly and breaks that separate tightly connected words. Listen around each boundary when the recording is fast or speakers overlap.
WebVTT is another timed-text format designed for web media. Choose SRT for broad editor and platform compatibility, and VTT when a web player or workflow explicitly requests it. The W3C maintains the WebVTT specification and guidance for timed text.

Questions and limits
Can an MP3 be converted directly to SRT?
Yes. Media2Text accepts MP3 audio and can export the reviewed timestamped transcript as SRT.
Does SRT include speaker names?
Media2Text SRT and VTT exports omit speaker names. Use a supported document export if you need speaker labels.
What if word-level timestamps are unavailable?
Media2Text uses stable segment timing for cue boundaries; word-level timing is only used when the source and transcription result provide it.
Should I choose SRT or VTT?
SRT is broadly compatible with editors and platforms. VTT is designed for web timed-text workflows and supports additional cue features.
