Record and send
Recording and sending are two separate actions. You record at your own pace, in the order you like, and nothing leaves until you ask for it.
- Record: the sound stays on your device, like a draft.
- Send: the sound goes to your Nextcloud, and its link is created.
The states of a paper
In the assignment's list, each student has a state:
You can close the page, reload it or move to another student: a draft stays kept on this device. If you leave the page in the middle of a recording, what you have said is kept too.
From one student to the next
At the top of a student's page, the arrows ‹ and › go to the previous and the next student of the list, whether they have a memo or not: to listen to the memos one by one, for example. The arrow on the left of the name goes back to the list.
The large round ▶ button plays a memo already sent right here: its sound is only fetched from your Nextcloud when you press it, and you stay in the tool. The QR code button, with an eye crossed out, shows it; under it, Test the link opens it as the student will.
Record again without losing anything
If you click Record again, the old recording is not erased. You listen to it next to the new one, and you choose.
So a wrong click costs nothing.
Send everything at once
When you have finished, open the assignment's list and click Send all N memos. The sounds leave one after the other.
If the connection drops, what has not left stays as a draft: you just try again.
Add to a memo, merge, cut
Forgot something? Add a recording, then say what was missing. A paper can only be sent with one sound, so the tool asks you what to do with the two:
As long as the choice is not made, the paper shows To validate, and it is not sent. To merge more than two, add them one at a time.
Cut a passage removes a slip, or a name said by mistake. Move the two handles around what should go, listen to it, then take it out. You can undo, and nothing changes until you click Keep this version. This also works on each of two recordings before merging them. All this happens on your device: nothing is sent.
Redo a memo that is already sent
After sending, Edit, then Record this memo again, lets you record a new version. Publish in the same place then replaces the sound at the same address: the QR code stays the same, and there is nothing to reprint.
Nextcloud keeps the old versions
The old sound can no longer be reached through the link, but Nextcloud normally keeps it in the file's Versions tab, visible to you alone. If it really has to disappear, delete it there.
Add a recording and Cut a passage, under Edit, also work on a memo already sent: the tool fetches its sound from your Nextcloud, you work on it, and Publish in the same place keeps the QR code. Until then, the students still hear the old version.
Delete a memo
Edit, then Delete this memo, after a confirmation, replaces it with the two tones heard before recording: the link stays, and so a QR code already printed still works, ready for another memo. As when a memo is redone, Nextcloud normally keeps the old sound in the file's Versions tab, visible to you alone.
A private memo, with assignments for the year, has no link of its own: its file is deleted, and if the student's QR code was playing it, the code goes back to two tones.
Why an MP3 file?
Browsers do not all record in the same format, and not all phones play all formats. So your device converts each memo to MP3, the format every phone can play. This conversion happens at your end: nothing is sent to do it.
The QR code on screen
After sending, the screen does not show the QR code, because what matters is the sheet of labels. If you want to see it, click the QR code button, with an eye crossed out.
Next: print the labels.
