Transcribe a long Olympus WS-853 recording straight from the recorder's USB plug.
An Olympus WS-853 recording uploads here as the MP3 it already is, and a three-hour lecture comes back as text in about six minutes. The first 20 minutes are free, and a $6 pack of 500 minutes transcribes the rest of a lecture that long with room for more.
From the lecture hall to text
The recorder sat on the desk all morning. The text is ready before lunch.
The file it already makes
The WS-853 records MP3, and an MP3 is one of the most common files we receive. Plug the recorder into a computer by its slide-out USB connector, copy the session file off, and drop it on upload page. No export step, no conversion and no splitting.
Size is not the problem
A full morning of MP3 at a high bitrate stays in the hundreds of megabytes. Before your first pack a file can be up to 2 GB, and the ceiling after one is 5 GB or 10 hours, so a single lecture or a back-to-back pair never comes near it.
Paid by the minute, not the month
A two-hour class is 120 minutes. The $6 pack holds 500, enough for that class and a little over six more hours. The minutes never expire, so a recorder that only comes out in exam season does not cost you a plan in the quiet months.
Notes with a table of contents
Each recording comes back with chapters at the points the topic changes, the names, dates and figures the lecturer said, and a brief with the main argument. Ask the chat which week a formula was introduced and it points you to the timestamp.
Why handheld lecture audio stalls elsewhere
A recorder that runs for hours meets tools built for ten-minute clips.
✗ Short-clip tools
Free tiers and phone apps often stop well before the end of a lecture, so a long WS-853 file gets cut or refused.

FAQ
Olympus WS-853 recordings, the common questions.
How long does a WS-853 lecture take to transcribe?
About 2 minutes for every hour of audio once the upload finishes. A three-hour session is usually ready in about six minutes, and you can close the tab while it runs because the result waits in your Library.
What does a semester of recorded lectures cost?
Twelve two-hour lectures are 24 hours, or 1,440 minutes. That fits the $12 pack of 2,000 minutes with 560 to spare, which works out to $0.36 an audio hour. A single three-hour lecture of 180 minutes fits the $6 pack.
Will a long WS-853 MP3 upload?
Yes. MP3 at 128 kbps is roughly 58 MB an hour, and even at 320 kbps an hour is about 144 MB. The limits are 10 hours or 5 GB per file, and up to 2 GB before your first pack.
Do I need to split or join files first?
No splitting is needed for one session. If you pressed stop and start during a class and ended up with two files, upload both; each one is its own transcript with its own chapters. Anything longer than 10 hours goes up as two files.
Which lecture languages work?
99 languages, detected automatically, including Tagalog, Korean, Japanese, Portuguese and Spanish. A class that moves between English and Tagalog is handled in one recording. Cebuano and other regional Philippine languages come back as a fast first draft, so plan one review pass.
What formats come out, and who sees the audio?
Every run gives you TXT, DOCX, SRT, VTT and JSON. Recordings are transcribed on our own servers and are never used for training, and removing a lecture from your Library removes its text as well.
