How lectures get recorded
Students usually record lectures on a phone, which saves an M4A or similar audio file, or on a small voice recorder that saves MP3 or WAV. Online classes held on Zoom or Teams leave an MP4 recording. Many universities also run a lecture capture system that records the room and posts the video to the course page, and some of those let you download the file. Teachers recording their own lessons often use a lapel mic plugged into a phone or camera.
All of these can be uploaded as they are. If the recording is in Google Drive or Dropbox you can paste the link instead. Before you record, check your institution's policy and ask the lecturer. Many universities require permission to record classes, and some restrict sharing the recordings.
Getting a recording that transcribes well
Distance from the speaker matters more than the phone you use. A phone in your bag at the back of a lecture hall picks up rustling, coughing and the projector fan, and the lecturer arrives as a faint echo. Some tips that help:
- Sit near the front and put the phone on the desk with the microphone end toward the lecturer.
- If the room has a PA system, sit within clear range of a speaker, since the amplified voice is louder than the lecturer's own.
- Lecturers recording themselves get the cleanest result from a lapel mic clipped to the collar.
- Turn on airplane mode or do-not-disturb so notifications do not interrupt or add buzzing.
- For a long day, record each lecture as a separate file. Shorter files are easier to name, upload and find later.
Studying from the transcript
The transcript arrives split into paragraphs with timestamps. The player highlights each line as it plays, so you can click a sentence in your notes and hear exactly how the lecturer explained it. This works well for revision: skim the text, then replay the two minutes you did not understand.
Read through the subject terms first. Names of researchers, chemical compounds, legal cases and course-specific jargon are the words most often misheard, and you can fix them in place. Formulas and equations come out as spoken words, not as maths notation, and anything that was only written on the board or slides will not be in the transcript at all.
For a seminar or tutorial where several students speak, speaker identification labels who said what. It is available on paid plans (Plus, Unlimited) or with a Minute Pack, not on Free or the no-sign-up trial. For a single lecturer you do not need it.
Lectures are supported in over 90 languages, chosen per file or detected automatically, including mixed Chinese and English. If you are studying in your second language, the Google Translate link opens the transcript for translation into your own.
Exports for students and teachers
Choose the export by how you will use it:
- DOCX (Word) to turn the transcript into study notes, with headings and highlights added by you.
- PDF to read on a tablet or print before an exam.
- TXT or Copy to paste into a notes app.
- SRT or VTT for teachers adding captions to a recorded lecture video, which helps students who are deaf or hard of hearing and anyone watching without sound.
- The AI prompt export to paste the transcript into ChatGPT or Claude and ask for a summary or practice questions. RocketScribe does not generate these itself.
A whole course in one place
Create a folder per course and keep each week's lecture in it, then export the folder in bulk before exams. Paid plans allow much longer files and batch uploads, which helps when you have a semester of recordings to process. The Free plan has a per-file length cap, so a long lecture may need a paid plan or a shorter split. Recordings are never used to train AI models, and you can delete them whenever you want.
