How It Works
Upload your WAV
WAV up to 2GB (MP3 and M4A also work). Drag and drop or click to browse. Your WAV is transcribed straight to text.
Transcribe
The spoken language is detected automatically, or pick it from the dropdown before uploading. A hybrid Parakeet-TDT and Whisper engine converts the audio to text with timestamps.
Download the transcript and subtitles
Preview the transcript in your browser, then download it as plain text (.txt) or as .srt / .vtt subtitle files. Noisy recording? Remove background noise before transcribing for a more accurate transcript.
Who uses this
Journalists and researchers transcribing interview recordings, students transcribing lecture audio, podcasters turning episodes into show notes, and anyone who needs an accessible text version of an audio recording.
Free, no account, and no monthly cap. Transcribe up to 90 minutes free, or up to 3 hours with Pro.
What happens to your WAV during transcription
WAV is uncompressed. Unlike an MP3, nothing was thrown away when the file was written: it holds raw PCM samples exactly as the recorder captured them. That is why a WAV is the best thing you can hand a transcription engine, and also why it is enormous. A stereo WAV at the standard 44.1 kHz and 16 bits runs about 10.6MB per minute, so a one hour interview is roughly 635MB before you have edited a thing.
The conversion runs in three stages. First the WAV is read and downmixed to a single 16 kHz channel, which is the sample rate the recognition models expect. This is where the size advantage quietly disappears: a 96 kHz studio master and a 44.1 kHz field recording arrive at the engine looking almost identical, which is good news, because it means you do not need a high-resolution file to get a good transcript. Second, the audio goes to the engine. VidClean runs a hybrid setup: Parakeet-TDT 0.6B v3 handles 25 languages including English, Spanish, Portuguese, French, German, Italian and Russian, and Whisper picks up everything else. Third, the recognized words are grouped into timed segments and written out.
Because every segment carries a start and an end timestamp, one upload produces a plain .txt transcript, an .srt subtitle file and a .vtt caption file together. Take the .txt if you just want the words in a document. Take the .srt or .vtt if the WAV is the production audio for a video, and drop it into your editor or into Add Subtitles.
Where WAV files come from, and what people transcribe them for
Field recorders and interviews
Handheld recorders default to WAV because it is lossless and universally readable. Journalists and qualitative researchers end up with hours of it, and a transcript is the only practical way to search, quote and cite the material. The .srt timestamps let you jump straight back to the moment a quote was said.
Audacity, Reaper and DAW exports
Editing software exports WAV by default so no generation of quality is lost between passes. If you have already mixed a podcast episode or a voiceover, transcribing the exported WAV gives you show notes and captions without going back to the session.
Meeting and call recordings
Windows recorders and a lot of conferencing and telephony software write WAV. Converting the recording to text gives you a written record you can skim for decisions and action items. VidClean does not label who is speaking, so a one to one call is easier to work from than a large group call.
Accessibility
A text alternative to audio content is a baseline accessibility requirement, and captions on any video carrying the same audio are another. Because one transcription produces the transcript and both caption formats, a single upload covers both obligations.
Lecture and archive digitisation
WAV is the usual archival master format, which means old talks, lectures and oral histories tend to sit in it. Transcribing that back catalogue turns audio nobody can search into text you can index. There is no monthly minutes cap and no daily file limit, so working through an archive file by file is fine.
Content repurposing
One recorded conversation can become a newsletter, a blog post, a thread and a set of short clips. The transcript is the starting point for all of them, because editing written text down is far faster than relistening to an hour of audio hunting for the usable part.

WAV limits, file sizes and supported formats
WAV is the one input format where file size is worth thinking about before you upload, because an uncompressed file grows at a fixed rate no matter what is in it. Here is roughly what a 90 minute recording weighs at the common settings:
| Sample rate and depth | Per minute | 90 minutes |
|---|---|---|
| 44.1 kHz, 16-bit, mono | 5.3MB | about 476MB |
| 44.1 kHz, 16-bit, stereo | 10.6MB | about 953MB |
| 48 kHz, 24-bit, stereo | 17.3MB | about 1.5GB |
| 96 kHz, 24-bit, stereo | 34.6MB | about 3GB, past the free cap |
- Length
- Up to 90 minutes per file free, or up to 3 hours per file with Pro. There is no monthly minutes cap and no daily file limit on either tier, so the length of a single recording is the only thing being measured.
- File size
- Up to 2GB free, or up to 5GB with Pro. As the table shows, most ordinary WAV recordings land well inside the free cap, and only high-resolution multichannel masters push past it. Worth knowing separately: the classic WAV container itself tops out near 4GB because it stores chunk sizes in 32 bits, which is why long sessions are often split by the recorder.
- If your WAV is too large
- Convert it to MP3 first and upload that instead. It sounds like the wrong advice for a lossless file, but the audio is downmixed to 16 kHz mono before recognition either way, so the transcript comes out effectively the same while the upload gets roughly ten times smaller and finishes far faster.
- Sample rate and channels
- Any standard PCM WAV works, mono or stereo, at any of the usual sample rates and bit depths. Recording at 96 kHz instead of 44.1 kHz will not produce a better transcript. The one case that genuinely reads worse is 8 kHz telephony-grade WAV, where the source audio really is missing detail the model needs.
- Input formats
- WAV, MP3 and M4A. If the audio is still inside a video file, run it through Video to MP3 first, or skip the step entirely and use Transcribe Video, which reads the video directly.
- Output formats
- A plain-text .txt transcript, an .srt subtitle file and a .vtt caption file, all free and all from the same upload. Pro adds a formatted .docx document and a .json file carrying the raw segments and timestamps.
- What affects accuracy
- Background noise, people talking over each other, heavy accents, and specialist vocabulary are the four things that cost the most accuracy. None of them are fixed by the file being lossless. If the recording is noisy, run Remove Background Noise or Enhance Speech first and transcribe the cleaned file.
- Privacy
- No account is needed and no file is kept. Your WAV and the transcript it produced are deleted from the servers 1 hour after processing, so download what you need before you close the tab, or email the transcript to yourself from the results panel.
Frequently Asked Questions
Everything you need to know about converting WAV to text with VidClean.
Is WAV to text free? expand_more
Yes, completely free, with no account, no watermark, and no monthly minutes cap. Convert as many WAV files to text as you want. Files are deleted 1 hour after processing.
Does it work on long WAV files? expand_more
Yes. WAV files up to 90 minutes are transcribed free, or up to 3 hours with Pro, and up to 2GB in size. Full-length interviews, lectures, sermons, and podcast episodes all work in one go.
What about MP3 or M4A files? expand_more
Yes. The same tool also converts MP3 and M4A audio to text. Try the dedicated MP3 to Text or M4A to Text pages, or drop any of the three formats here.
Does it label who is speaking? expand_more
No. VidClean does not currently support speaker identification, so the transcript is not split by speaker. The .txt and .srt files are fully editable, so you can label speakers yourself.
Is there a monthly limit? expand_more
No. There is no monthly minutes cap and no daily file limit, unlike Otter (300 minutes per month) and Turboscribe (3 files per day). The transcript, .srt, and .vtt downloads are always free.
Is my file private? expand_more
Yes. Files are automatically deleted from our servers 1 hour after processing.
How do I convert a WAV to a TXT file? expand_more
Upload the WAV above and, when it finishes, click ".TXT transcript" in the results panel. You get a plain-text .txt file with no timestamps and no markup, ready to paste into a document. The .txt download is free and does not require an account.
Can I get an SRT or VTT subtitle file from a WAV? expand_more
Yes. Every transcription produces .srt and .vtt files alongside the .txt, because the words are timestamped as they are recognized. This is the usual route when the WAV is the production audio for a video: transcribe the audio, then load the .srt into your video editor. Both subtitle downloads are free.
My WAV file is too big to upload. What should I do? expand_more
Convert it to MP3 and upload that. The audio is downmixed to 16 kHz mono before recognition either way, so the transcript comes out effectively the same while the file gets roughly ten times smaller. The free cap is 2GB and Pro raises it to 5GB, but only high-resolution multichannel WAV masters usually run into it.
Is a WAV more accurate to transcribe than an MP3? expand_more
In practice, no. WAV is lossless and MP3 is not, but both are downmixed to 16 kHz mono before recognition, which discards most of the difference. What the recording contains matters far more than what container it is in: a clean MP3 of a close microphone will beat a lossless WAV of a noisy room every time.
How long does it take to convert a WAV to text? expand_more
It depends on the length of the recording and on your upload speed, and with WAV the upload is usually the slow part because the files are large. You do not have to watch it run: leave the tab open and come back, or enter your email while it is processing and get a message when the transcript is ready.
