@shizishan: There is an app/extension LectureRecordings that allows to record audio while taking notes.
To record audio while taking notes with LectureNotes, do not start LectureRecordings but LectureNotes. Then, open a notebook and select `Start recording´ in the menu at the app's launcher icon to start recording, and select `Stop recording´ in this menu to stop recording; or enable the `microphone´ icon in the app's menu settings, click on the `microphone´ icon to start recording, and click again on the `microphone´ icon to stop recording. Please note that the noise caused by your stylus on the device surface is inevitably recorded by the app when using the device's built-in microphone, therefore it is recommend to use an external microphone.
To replay your recordings, open the notebook in `notebook replay´ (either directly from the notebooks board by long-clicking on the notebook and selecting `Notebook replay´ in the popup menu, or by opening the notebook normally and selecting `Notebook replay´ in the main menu), then the recordings will be on the left and the notebook on the right, the divisor can be moved horizontally by click-and-drag.
There is also a search functionality, select `Search recordings´ in the main menu and click on the area in question. This will forward the audio recording to the moment in time during which you wrote in this area for the first time (if there are multiple recordings, you will get a list to choose from).
