Advanced Lecture Recording and Synchronized Notes

Please add an advanced lecture recording feature that synchronizes the audio recording with everything the user does in the note during the lecture.

The system should record the lecture audio and automatically distinguish between different speakers when possible, such as the lecturer and students. Each speaker should ideally be identified separately in the transcript, for example "Speaker 1", "Speaker 2", or with custom names.

The most important feature is synchronization between the recording and the user's handwritten notes.

If the user writes, draws, highlights, erases, or adds something to the note while the recording is running, the app should save the exact timestamp of each action.

When the recording is played back, the notes should be reproduced in synchronization with the audio. For example, if the user draws a diagram at 15:32 during the lecture, playing the recording should show that drawing being created at approximately 15:32, following the same timing as the original writing process.

Ideally, the user should be able to see a timeline showing important actions and jump directly to them. Tapping a handwritten note, drawing, highlight, or other action could take the user to the exact moment in the recording when it was created.

The recording should also support automatic speech-to-text transcription, preferably with strong support for both Arabic and English and the ability to handle mixed-language lectures.

It would be especially useful if medical terminology and other specialized terminology could be recognized accurately.

Please also consider adding:

- Automatic timestamps for important moments

- Searchable transcripts

- Speaker labels in the transcript

- Ability to rename speakers

- Ability to jump from transcript text to the corresponding point in the recording

- Ability to jump from a note or drawing to the corresponding point in the recording

- Playback speed controls

- Background noise reduction and voice enhancement

- Automatic detection of important sections or topics

- Bookmarks during recording

- The ability to continue writing while recording without interrupting either function

- Exporting the recording, transcript, and synchronized notes together

The overall goal is to create a synchronized lecture record where the audio, transcript, handwriting, drawings, highlights, and other note actions remain connected to the same timeline.

This would allow students to revisit not only what the lecturer said, but also exactly what they wrote or drew at that moment, making revision much faster and more effective.
