What is WAV to Text?
WAV to Text transcribes uncompressed WAV recordings, including the 48 kHz and 24-bit files that field recorders and studio interfaces produce. Nothing is converted to a compressed format first, so transcription runs on the original audio. Interview series, oral history sessions, and room recordings come back as timestamped text that can be corrected and exported.
Why choose WAV to Text?
WAV to Text is aimed at recordings made with a microphone rather than a phone: room tone, two speakers across a table, a recorder left running. The file is uploaded as recorded, the spoken language is detected, and each line carries the time it occurs, so a quote can be played back in the original.
Are Large WAV Files Sitting on a Drive Without a Transcript?
A field recorder produces hours of clean audio and no index. Playback means scrolling a waveform, and a quote has to be found by ear before it can be typed. Converting the WAV to MP3 first adds a lossy copy without changing the speech. WAV to Text works on the original file, returns timestamped text, and leaves the recording untouched.
What makes WAV to Text different?
WAV to Text keeps the original recording as the reference. Timestamps point back to the uncompressed file, and no intermediate MP3 is created between the microphone and the transcript.

How to use WAV to Text in 3 steps
- 1
Upload the WAV file
Add the file from a field recorder, an interface, or a phone, or paste a link to a WAV that is already hosted.
- 2
Confirm the recording language
Detection covers single-language sessions; set the language when the recording starts with room tone or mixes two languages.
- 3
Review the transcript
Check names and technical terms against the audio, then export text for the interview file or SRT for captions.
Start with one long session from the archive and compare the draft against the recording. WAV to Text accepts the file as the recorder wrote it, with no compressed copy in between.

Frequently asked questions about WAV to Text
Does WAV to Text support 24-bit and 48 kHz files?
Yes. Files written at 48 kHz and 24-bit, which is the usual setting on a field recorder or an audio interface, can be uploaded directly. There is no need to downmix to 16-bit or resample first. The transcription works from the file as written, so the original remains the reference for any later check.
Why not convert the WAV to MP3 first?
Converting to MP3 adds a lossy generation and a second file to keep track of, without making speech easier to recognise. WAV to Text takes the uncompressed file, so the audio that reaches the recognizer is the audio that was recorded. That also avoids the temptation to delete the original after a smaller copy is made.
How large a WAV file can be uploaded?
The upload ceiling is 100MB, which at 48 kHz and 24-bit is a few hours of stereo audio; speech is processed up to three hours. A full day of recording usually exceeds both limits, so a session should be split at a natural break, such as the end of an interview, before it is submitted.
Can two speakers at one table be separated?
Yes, when speaker separation is enabled. Turns are labeled, which matters for an interview where the questions and answers need to stay distinct. Crosstalk and a speaker who leans away from the microphone remain the hard cases, and those passages are worth a listen before the transcript is quoted.
Does the transcript keep timestamps?
Every passage carries the time it occurs in the recording, counted from the start of the file. A reviewer can therefore jump to a phrase in the original WAV, which is useful when a name or a number is in doubt. The transcript and the recording stay in step even for a long session.
Does channel layout affect the result?
A mono file from a single microphone is the simplest input. Stereo files are handled as they arrive, but if one channel holds a different speaker, separating the channels into their own files can produce a cleaner transcript than submitting the combined track, and each half then gets its own speaker label.
How accurate is transcription of clean field audio?
Clean audio with low noise and a close microphone produces the best results, which is the usual case for a field recorder. Accents, overlapping speech, and specialist vocabulary still need review. A short listen against the timestamps is enough to decide whether a session needs a full proofread.
Can the transcript be exported for research use?
Plain text can be exported for coding, quoting, or archiving, and SRT is available when a recording will be published with captions. Because the original file is unchanged, an archive can keep the WAV and its transcript together, with timestamps providing the link between a claim and the audio behind it.
