Audio length checker

Drop a recording and see how long it is — and what that length costs to transcribe, at every rate, before you upload anything. The file is read in your browser; it never leaves your device until you choose to send it.

How the audio length checker works

  1. Drop a recording onto the box, or choose a file.
  2. The browser reads its length — nothing is uploaded.
  3. See the duration and what it costs at every service rate, standard and rush.
  4. Upload the file only when you want the confirmed price and a transcript.

Why the length decides the price

Transcription is priced per audio minute — the length of the recording, not the number of words in it and not the time it takes to type. A dense interview and a slow lecture of the same length cost the same, because an editor works through both minute by minute.

That makes the length the first thing worth knowing about a file. It tells you the price before you commit, and it tells you whether the job belongs in one order or several.

What counts as billable time

  • Total length, rounded up. A 12-minute-10-second file is 13 billable minutes.
  • Silence and music count. They are part of the recording an editor has to listen through and mark.
  • Video counts by its audio. A 40-minute webinar is 40 billable minutes.
  • Every file in the order adds up. Six 10-minute interviews are 60 billable minutes.

There is a $3.00 minimum order. Rush delivery within 24 hours adds 50%, and the checker shows both prices.

Price by length, at two rates

Standard turnaround, at the general rate of $0.80 per minute and the legal rate of $1.40 per minute:

Recording lengthGeneralLegal
10 minutes$8.00$14.00
30 minutes$24.00$42.00
1 hour$48.00$84.00
2 hours$96.00$168.00
3 hours$144.00$252.00

The full rate card — business, academic, medical, legal and captions — is on the cost per minute page.

Checking a file you are about to send

If the length surprises you, it is worth a look before the order goes in. Two common causes: a recorder that kept running after the interview ended, and a video file whose audio track is longer than the picture.

Trim what you do not need. You are billed for the file you send, not the meeting you recorded.

Audio length checker — questions

How do I check the length of an audio file?

Drop the file into the box above. The browser reads its metadata and shows the duration in minutes and seconds, along with the price for that length at each of our rates. Nothing leaves your device until you press upload.

Is my recording uploaded?

No. The file is read locally by the browser and discarded when you close the page. Uploading only happens if you press the upload button, and then it goes through the same encrypted upload the order form uses.

What if the browser cannot read my file?

A few formats — AMR, WMA and some MKV files — cannot be decoded by browsers. In that case the page tells you so; upload the file and the confirmed length and price appear as soon as the upload finishes.

Does it work for video files?

Yes. MP4, MOV, M4V and WebM are read the same way; the price is based on the audio length, not the picture.

What counts as billable audio?

The total length of your recordings, rounded up to the next whole minute. Silence and music inside a recording count as audio time, because they are part of the file an editor has to work through.

Can I check several files at once?

The checker reads one file at a time. For a multi-file order, check each one and add the durations together — or upload them all at once and the order form totals them for you.

Transcripts checked by people, quoted in minutes

Upload your recordings and see the confirmed USD price as soon as the upload finishes. Every transcript is drafted, edited by a professional and quality-checked before delivery.
