Listen to your lecture again without going online

If you want to revisit a lecture somewhere without internet, save the audio before you leave. Rebrief for Mac lets you export a recorded lecture and its transcript, so you can listen without reopening the course website. Keep a reference to the explanation you need, then check that the saved audio plays offline. You may still need the slides when the lecturer refers to something on screen.

Choose the lecture you want to take with you

Open the recording in Rebrief and listen to the part you plan to study. Make sure the instructor is audible and that you have the full explanation, including any question that led to it. Do this while you still have access to the course, so you can recover a missing passage from a permitted replay or request a transcript.

Check that the course allows you to record and retain the lesson, including other students' contributions. If it already provides an audio download you are allowed to keep, use that. Paying for access does not by itself establish permission to make your own copy.

If you haven't recorded the lesson yet, start Rebrief manually while the lecture plays on your Mac. Listen-only sessions don't trigger automatic recording. Free recordings stop at 15 minutes, so unlock longer recording before relying on it for a full class. Rebrief requires an Apple Silicon Mac with macOS 15 or later; the support page covers recording setup.

Save the audio somewhere you can find it

Use Export in Rebrief to save the lecture audio to a folder on your Mac. Give the folder the course name and lecture topic so you'll recognize it when you're away from the course website. Rebrief's export instructions confirm that you can save the audio outside the app.

Listen to the exported files and identify the one containing the instructor's explanation. Keep the other audio too if it contains your question or context you'll need later. You should be able to understand the passage from the material you've saved, without trying to remember what someone asked beforehand.

If you can hear only yourself, return to the original recording in Rebrief. Its troubleshooting guidance explains that missing system-audio permission can leave the instructor unrecorded. Fix that for future classes; for this lesson, use an allowed replay or supplied transcript to fill the gap.

Keep the explanation's transcript beside it

Let Rebrief finish transcribing after the recording ends, then export the transcript as plain text into the same folder. You'll have a readable copy to consult when a term is unfamiliar or you need to find a particular explanation. Prepare it before leaving; if you intend to transcribe offline in Rebrief, finish the initial model downloads first.

Find the passage you want to revisit and listen while reading it. Correct any words that change the meaning in your study copy, especially numbers and technical terms. Keep the checked passage with a short note about where to begin listening in the saved audio. Check that position once in your player so you can return to it later.

You don't need to annotate the whole lecture before taking it with you. Start with the explanation that prompted you to save it. Include the relevant slide or handout page in the note if the spoken answer needs that context.

Open it once with the internet disconnected

Before relying on the files away from home, close the course website and disconnect your Mac from the internet. Open the saved audio in your usual local player and play the explanation you marked. Open the transcript too, so you know both are available.

For QuickTime Player, choose File > Open File and select the audio. Apple's playback guide explains how to open a file and move through it. Check your own export in the player you'll use; this Rebrief workflow has not yet been demonstrated with a supplied lecture recording.

[Evidence needed: a permitted Rebrief lecture export that plays offline, with a checked transcript passage matched to the explanation in the saved audio.]

If the file won't open, compare it with the recording in Rebrief and try exporting again. For an intact file that your player doesn't support, Apple's media playback guidance recommends using an app that supports it. Resolve that before you leave, then try opening it offline again.

Bring the slides when the explanation needs them

Rebrief records audio, so a lecturer pointing to a diagram or working through an equation can leave you missing part of the lesson. Save permitted slides or handouts beside the audio. If you can't retain the visuals, write the explanation in your own words while you can still see them, or plan to review that section online.

For your next offline study session, export one lecture from Rebrief, save the passage you want to revisit, and open both files with the internet disconnected before you leave.
