Convert Audio to SRT with FastTranscriber

Convert audio files to SRT subtitle format. Generate timestamped subtitles from MP3, WAV, or any audio. Here is a quick guide to completing the process with FastTranscriber:

  1. Step 1: Start for Free

    Open FastTranscriber and begin with the free daily allowance. No account or credit card is required.

  2. Step 2: Upload Your Audio

    Open "Transcribe Files" and select your audio or recording. MP3, WAV, M4A, FLAC, OGG, AAC, and WebM are supported directly.

  3. Step 3: Generate the Captions

    Click "Transcribe" to convert the spoken audio into caption text with accurate, speech-synced timestamps.

    Review the text and timing, then download an SRT subtitle file for your video editor or publishing platform.

Create subtitles from a separate audio track

Audio to SRT is useful for narration, recorded talks, and audio episodes that will accompany a video. FastTranscriber turns the speech into timed subtitle cues; you then review and place those cues in the player or editing project that uses the audio.

Keep the audio and video timeline together

Start with the final narration or conversation file. If the audio begins several seconds into your video, its subtitle times will need the same offset in your editor. When audio is split into clips or rearranged, a subtitle file made from the original continuous recording will need corresponding timing adjustments.

Know when transcription is needed

Use this workflow when you have speech in an audio file and need to create subtitle text. If you already have reviewed captions in VTT format, converting that file to SRT avoids generating a fresh transcript. Changing a subtitle format preserves existing wording; transcribing audio creates a new draft to check.

A script without timings is different again. The exported SRT follows the recorded speech, which may include pauses, changed wording, or a different order from the script used during recording.

Make the cues readable in context

Check names, abbreviations, and technical terms, then play the subtitles with the finished media. Adjust long lines and cue boundaries in your caption editor where needed. For an audio episode published over a still image, review the whole timeline just as you would a filmed video: the words still need enough time on screen to be read.
