How do you convert a WAV file to text?
Upload the WAV file to 1Transcribe — uncompressed files up to 5 GB and 10 hours are accepted, so there is no need to compress or split it first. OpenAI's Whisper models transcribe the recording with up to 99.9% accuracy and automatic speaker labels, and you can export the text as DOCX, PDF, SRT, or TXT. WAVs under 5 minutes are free with no signup.
The problem with WAV files: they're huge
WAV is uncompressed PCM audio — the format professional gear records in because it loses nothing. The trade-off is size: an hour of stereo 44.1 kHz WAV is roughly 600 MB, and a long session easily passes a gigabyte. That is exactly where many online converters fail, rejecting uploads over 100-500 MB or forcing you to compress the file first. 1Transcribe accepts a single file up to 5 GB and 10 hours — among the highest limits of any transcription service — so you upload the original WAV untouched and keep every bit of the quality Whisper can use.
Where WAV recordings come from
If you're holding a WAV file, it probably came from professional or semi-professional equipment:
- Studio and field recorders — Zoom, Tascam, and Sound Devices units record WAV by default.
- Court and legal recording systems — hearings and depositions are often captured as uncompressed WAV.
- Dictaphones and conference systems — many corporate recorders save meetings as WAV.
- Podcast and interview masters — the pre-edit master is usually WAV before it becomes an MP3.
- DAW exports — bounces from Audacity, Pro Tools, Logic, and Reaper are WAV.
Uncompressed audio, maximum accuracy
Because WAV carries the full, unprocessed signal, it is the best-case input for speech recognition: no compression artifacts, no lost frequencies. On clear WAV recordings, 1Transcribe's OpenAI Whisper models reach up to 99.9% accuracy, and automatic speaker diarization keeps multi-voice recordings — depositions, panel interviews, band meetings — attributed correctly. All 99+ languages are supported with auto-detect, and speech in any language can be translated to English text. There is nothing to install: it runs in your browser and in the iOS, Android, Mac, and Windows apps.
From WAV to a usable document
Once the transcript is ready, edit it in the browser and export to Word (.docx) for legal records and reports, PDF for sharing, TXT for plain text, or SRT if the recording accompanies video. Long recordings also benefit from AI summaries — a 3-hour hearing collapses to its key points in one click. Files under 5 minutes are free; Unlimited is US$19.99/month or US$49.99/year (about US$4.17/month), with batches of 5 files at a time. Files are never used to train AI and are deleted after 14 days.

Frequently Asked Questions
Everything you need to know about 1Transcribe.
Can I transcribe a WAV file for free?
Yes — WAV files under 5 minutes transcribe free with no signup. Longer recordings, up to 10 hours and 5 GB each, need an Unlimited subscription at US$19.99/month or US$49.99/year (about US$4.17/month).
My WAV file is over 1 GB — will it upload?
Yes. 1Transcribe accepts single files up to 5 GB, which covers roughly 8+ hours of stereo uncompressed WAV. Many competing tools cap uploads at a few hundred megabytes; here you upload the original without compressing or splitting it.
Should I convert WAV to MP3 before transcribing?
No — and it's better not to. WAV is uncompressed, so it gives the speech-recognition model the cleanest possible signal. Upload the WAV as-is for the best accuracy.
How accurate is WAV transcription?
On clear recordings, OpenAI's latest Whisper models reach up to 99.9% accuracy. Uncompressed WAV is the ideal input because there are no compression artifacts to interfere with recognition.
Does it handle multi-speaker WAV recordings like depositions?
Yes. Automatic speaker diarization labels each voice, so hearings, depositions, panel interviews, and meetings come back as readable, attributed dialogue.
Can I export the transcript to Word for a legal record?
Yes. One click exports to Microsoft Word (.docx), or choose PDF, plain text (.txt), or timestamped SRT subtitles.
What sample rates and bit depths are supported?
All standard WAV variants work — 16-bit or 24-bit, mono or stereo, from 8 kHz dictaphone recordings up to 96 kHz studio masters. The file is processed as-is.
Are my WAV files kept confidential?
Yes. Files are never used to train AI models and are automatically deleted after 14 days — important for legal, medical, and archival material.
