Free online WAV to SRT converter

Source format overview

WAV is an uncompressed audio file format commonly used for high-quality sound storage and editing. It is widely used by audio engineers, podcasters, video editors, transcription workflows, and anyone working with original or lightly processed recordings. Typical WAV files contain speech, music, or other audio that may later be edited, archived, or transcribed.

Target format overview

SRT is a plain-text subtitle format used to store captions and subtitles with time codes and text lines. It is supported by most video players, editing tools, and streaming platforms. SRT files are lightweight, easy to edit, and ideal for adding subtitles to videos after transcription.

How to perform the conversion

Converting WAV to SRT is not a direct format transformation, because WAV contains audio while SRT contains subtitle text. The process usually has two steps: speech-to-text transcription and subtitle formatting.

1. Transcribe the WAV audio using speech recognition software. Good desktop options include Whisper tools, Subtitle Edit, Aegisub with transcription support, or professional transcription software.
2. Generate subtitle timing so the text is split into subtitle segments with timestamps. Many transcription tools can create timed subtitles automatically.
3. Export or save as SRT. In subtitle editors, this is usually done through File → Save as or File → Export, then choosing SubRip (*.srt).
4. Review and correct the result. Check punctuation, speaker changes, line breaks, and timing before using the file in a video project.

If you want a simple online workflow, you can convert the file on 101convert.com for free, without installing any software, provided the service supports transcription-based conversion for your file.

Example desktop workflow with Subtitle Edit: open the WAV file, run speech recognition or import an existing transcript, then use File → Save as and select .srt.

Notes on quality and limitations

WAV to SRT conversion depends on speech recognition quality, not just file format compatibility. Clear speech, low background noise, and a single speaker usually produce better subtitles. Music, overlapping voices, accents, and poor recording quality can reduce accuracy.

Because SRT stores only text and timestamps, it cannot preserve the original audio. It also does not support advanced styling, multiple subtitle tracks in one file, or rich formatting beyond basic line breaks. If the WAV file contains non-speech audio, the result may be incomplete or require manual editing.

For best results, always proofread the generated subtitles and adjust timing before publishing or embedding them in a video.
