The Short Answer
A WAV to text converter turns the speech inside an uncompressed .wav recording into written words. TurboCast does it with AI: upload the file, and a few minutes later you have a transcript with timestamps, speaker labels, an AI summary and clickable chapters.
WAV is what field recorders, Audacity, every DAW and most call-recording systems produce when you ask for full quality. Nothing is thrown away, which is great for the transcript and hard on the upload: a WAV is roughly ten times the size of the same recording as an MP3. The free plan allows 100MB per file, which is about 10 minutes of CD-quality stereo, so the section below on file size is worth thirty seconds before you upload.
The rest of the numbers: 3 free transcriptions a day, up to 30 minutes per file, no credit card. Paid plans raise that to 500MB and 210 minutes with unlimited transcriptions. Detection covers 100+ languages, and the file is deleted 24 hours after processing. If your recording is in another format, the general audio to text converter linked at the bottom takes anything.
How to Convert WAV to Text in Three Steps
No software, no format conversion, no re-encoding. The WAV to text converter reads PCM audio directly, so the file goes in exactly as your recorder or editor saved it.
Upload your WAV
Drag the file into the converter at the top of the page. A 16-bit stereo WAV runs about 10MB a minute, so check the size table below if the recording is long. Free files can be up to 100MB and 30 minutes; Pro raises that to 500MB and 210 minutes.
The AI transcribes it
Language detection is automatic across 100+ languages. Timestamps are added to every paragraph and two or three speakers get labeled. Uncompressed audio gives the model the cleanest possible input, so WAV to text results are as good as the recording itself.
Review and export
Read the transcript next to its summary and chapters, correct any names, then export as TXT, SRT, VTT, PDF or DOCX, or send it on to notes and flashcards.
How Many Minutes of WAV Fit in 100MB?
This is the question every WAV to text tool avoids. Uncompressed audio is big, so the free upload limit is hit by file size long before the 30-minute duration cap. Three ways to stay under it, none of which hurt the transcript.
Export mono instead of stereo
Speech does not need two channels. In Audacity or your DAW, mix down to mono before exporting and the file halves: about 20 minutes of 44.1 kHz audio now fits in 100MB.
Drop the sample rate to 16 kHz
Speech recognition models work at 16 kHz internally, so a 16 kHz mono WAV loses nothing that matters. That is roughly 1.9MB a minute, or about 52 minutes in 100MB.
Or just save it as MP3
A 128 kbps MP3 of the same recording is about a tenth of the size and transcribes identically. The MP3 to text page takes it from there, and the paid plans take 500MB WAV files if you would rather not convert at all.
WAV Size vs Minutes, at a Glance
Approximate figures for 16-bit PCM. Use them to decide whether to upload as-is, export a lighter WAV, or convert to MP3 first.
| Recording | Size per minute | Fits in 100MB (free) | Fits in 500MB (Pro) |
|---|---|---|---|
| WAV 44.1 kHz stereo (CD quality) | ≈ 10.1 MB | ≈ 10 min | ≈ 49 min |
| WAV 48 kHz stereo (video, field recorders) | ≈ 11 MB | ≈ 9 min | ≈ 45 min |
| WAV 44.1 kHz mono | ≈ 5 MB | ≈ 20 min | ≈ 99 min |
| WAV 16 kHz mono (speech export) | ≈ 1.9 MB | ≈ 52 min | 210 min cap |
| MP3 128 kbps (same recording) | ≈ 1 MB | 30 min cap | 210 min cap |
More Than a Plain WAV Transcription
Most WAV to text converters hand you a wall of text. TurboCast keeps the structure of the recording and adds the layer you would otherwise write yourself.
Clickable timestamps
Every paragraph is anchored to its moment in the recording. Click a line to jump back and hear exactly what was said.
Speaker labels
Two or three voices are separated and labeled reliably. Rename Speaker 1 to a real name once and the whole transcript updates.
Summary, chapters and five export formats
An AI summary, chapter list and key points are generated with the transcript. Export as TXT, DOCX or PDF for reading, or SRT and VTT when you need a timed subtitle file; captions on a video are the AI subtitle generator's job.
Turn Your WAV Transcript into Notes, Flashcards or a Podcast
This is where TurboCast stops being just a WAV to text converter. The same transcript feeds every other tool on the site without re-uploading the big file.
Smart Notes
Structured notes, key concepts and takeaways generated from the recording with the AI note taker. An hour of seminar tape becomes two pages you can revise from.
Flashcards and quizzes
Turn the recording into spaced-repetition cards or a quick quiz with the AI flashcard maker. Useful for exam prep and language learning.
AI podcast
Have the content explained back to you as a narrated episode from the AI podcast generator, ideal for reviewing on a commute.
Who Converts WAV to Text, and Why
WAV shows up wherever someone chose quality over file size. Four WAV to text workflows we see every week.
Podcasters and audio producers
The master recording from a Zoom H-series recorder or a DAW session is a WAV. Transcribe it once for show notes, chapters and a searchable archive.
Journalists and oral historians
Field interviews recorded at full quality become quotable, timestamped text. Jump back to the exact second when a quote needs checking.
Researchers and students
Focus groups, seminars and lab meetings recorded in WAV turn into notes, then flashcards, without anyone typing for six hours.
Teams with call recordings
Phone systems and dictation devices often export WAV. Turn a week of calls into readable minutes with speaker labels intact.
