Transcribe a WAV file, however large.

WAV files are big, and that is the only hard thing about them. Drop one here as it is, 24-bit or 32-bit float included: up to 500 MB in this box, up to 5 GB on the main upload page, and you read the summary free.

The file you have

How big is an hour of WAV?

16 kHz mono, 16-bit
About 115 MB an hour. Typical of call recordings and dictation.
44.1 kHz stereo, 16-bit
About 605 MB an hour. The CD-quality default of most recorders and editors.
48 kHz stereo, 24-bit
About 1 GB an hour. Field recorders and video work.
48 kHz stereo, 32-bit float
About 1.4 GB an hour. Newer recorders; read directly, no conversion.
Limit here
5 GB or 10 hours per file, whichever comes first. A CD-quality stereo WAV reaches 5 GB at a little over eight hours.

Sometimes a link works. Upload the file, or paste a direct link to it if it already sits online (an address ending in .wav, or a Google Drive link set to 'Anyone with the link'). For a large WAV a link saves you the upload.

How it works

Three steps, the first one is the only one that takes any thought.

1

Check the size

Under 500 MB: drop it in the box on this page. Over that: use the main upload page, which sends large files in parts.

2

Upload it as it is

No need to convert to MP3 or change the bit depth. Stereo files are mixed to one track for transcription.

3

Read, then export

Free preview and summary; a pack opens the full transcript with TXT, DOCX, SRT, VTT and JSON.

Good to know

What trips people up, and what to do about it.

Example. A three-hour board meeting recorded at 44.1 kHz stereo is a 1.8 GB WAV. It uploads from the main page in parts and the transcript is ready about six minutes after the upload finishes, with chapters per agenda item. Checked 4 October 2026: 24-bit and 32-bit float WAV files uploaded through this site came back as text.

What comes back

More than a wall of text.

The same four things for every WAV recording, whatever its length.

A transcript with timestamps

Every line carries its time. Click a line to hear that second again, or search a name or phrase and jump to each place it was said.

A summary, chapters and key quotes

A brief with the takeaways, chapters with their start times, and the quotes worth keeping. Speakers are identified and named in the summary, key quotes and chapters.

Questions answered from the recording

Ask where a topic came up or what was decided, and get the answer with the time it was said, instead of scrolling the whole text.

Every export

TXT, DOCX, SRT, VTT, JSON from the same transcript: a document to edit, caption files for video, plain text to paste, structured data for your own tools.

Pricing

Free preview. Packs from $4, and the minutes never expire.

A three-hour meeting is 180 minutes, so the $4 pack (500 minutes) covers it twice. Every recording gets a free preview and a summary you can read before paying; a pack opens the full transcript and every export. Packs are one-time purchases with no subscription and no seat fee.

Pick a pack to open secure checkout. Workspace is $19 a month for unlimited transcription (300-hour fair-use mark). Full pricing

What we measured, last 30 days

1,901 recordings, 830 audio hours, 64 languages detected. An hour of audio came back in 3.7 minutes for half of the recordings and within 19.7 minutes for nine in ten, measured from the moment the file landed to the finished transcript. Refreshed 2026-10-02; method on how we test.

FAQ

Transcribing WAV files, answered.

How do I transcribe a WAV file?

Drop it in the box on this page if it is under 500 MB, or use the main upload page for anything up to 5 GB. The transcript comes back with timestamps in about two minutes per hour of audio.

Do I need to convert WAV to MP3 first?

No. WAV is read directly at any common sample rate and bit depth. Converting only helps if you want a faster upload.

Do 24-bit and 32-bit float WAV files work?

Yes. Both are read directly.

My WAV is larger than 5 GB. What can I do?

Save it as MP3 or FLAC first; the speech is unchanged and the file shrinks five to ten times. Any audio editor does this, and so does one ffmpeg line: ffmpeg -i recording.wav recording.mp3.

How is this different from the WAV to text page?

It is the same engine. That page is the quick converter for a short clip; this one is about long and large WAV recordings, their sizes and what to do near the limits.

What does it cost to transcribe a WAV file?

The preview and the summary are free. A pack opens the full transcript: $4 for 500 minutes, $8 for 1,000 minutes, $12 for 2,000 minutes, $24 for 5,000 minutes. Packs are one-time, credits never expire, and Workspace is $19 a month if you transcribe every week.

How long can the recording be?

One file can run up to 10 hours or 5 GB. The box on this page takes files up to 500 MB; a larger file continues on the main upload page, which uploads it in parts. Most recordings come back in about two minutes per hour of audio.

Is the recording kept private?

Recordings are transcribed on our own servers and are never used for training. You can delete a recording and its transcript at any time.
