Offline audio for a classroom with bad wifi

Convert a talk, lecture, or podcast episode to a 320kbps MP3 you can play from a laptop, a phone, or a USB stick, with nothing to install.

  • MP3 at 320kbps
  • M4A, WAV, and FLAC too
  • Whole playlists in one batch
  • Nothing to install on a school machine

The room's wifi will fail during the lesson. Have the file on the laptop before it does.

The workflow

  1. 1

    Check you are allowed to use it

    Openly licensed lectures, Creative Commons talks, government and museum recordings, your institution's own uploads, and your own recordings are all fair game. A commercial audiobook or a music track is not. This step is not optional and it takes ten seconds.

  2. 2

    Copy the link and choose MP3

    Paste the video link and pick Download MP3. It encodes at 320kbps, the highest bitrate MP3 supports, which is well beyond what a classroom speaker will ever reveal.

  3. 3

    Do it the evening before, not in the lesson

    A long lecture takes up to a minute to convert. The progress runs on the button and a notification fires if you switch tabs, so you can start it and go back to your marking.

  4. 4

    Put it somewhere that does not need a network

    Copy the file to the machine you will actually teach from, or to a USB stick. A file in cloud storage is still a file that needs the wifi you do not trust.

Why this works on a locked-down school laptop

ClipKoala runs entirely in the browser. There is no installer, no extension requirement, no admin password, and no account. On a managed machine where you cannot install anything, that is usually the difference between having the audio and not having it.

It also means nothing to explain to IT beyond a website. If your institution filters by category, ask them to allow the domain rather than trying to work around the filter.

Choosing a format for a classroom

MP3 at 320kbps is the right default: it plays on every device in the building, including the ancient one wired to the projector. M4A is the same quality at a smaller size and is the safer choice on Apple hardware. WAV and FLAC exist for when you plan to edit the audio into teaching material, not for playback.

For a series, paste the playlist link. ClipKoala expands it into a batch of its latest videos and you pick the audio format per item, or use Save all.

What this will not do

  • Copyright applies in a classroom too. Educational use is not a blanket exemption, and the rules differ by country and institution. Check your own policy.
  • Private, members-only, and unlisted-with-a-password recordings cannot be fetched.
  • Live streams cannot be captured. Wait until the replay is published.

FAQ

Questions from teachers

Is it legal to download a lecture for my class?

It depends on the licence. Openly licensed and Creative Commons material, public-domain recordings, your institution's own content, and anything you made yourself are fine. Commercial content generally is not, and educational use is not an automatic exemption anywhere. Check your institution's policy before the lesson, not after.

Do I need to install anything on a school computer?

No. ClipKoala is a website. There is no installer, no extension needed, and no admin rights required, which is usually the whole reason a teacher ends up here.

What bitrate do the MP3 files use?

320kbps, the highest MP3 supports. There is nothing to configure and no quality tier to pay for.

Can I convert a whole lecture series at once?

Yes. Paste the playlist link and it expands into a batch of the most recent videos in that playlist, each with its own audio format options.
