Android Sound Recording app
App is a demo, it has got it's functionalities, but the UI is not any kind of user-friendly.
Android app, should work properly on Android API 24 (7.0 Nougat)
Application provides recording possibilities, with cutting silent blocks of a recording.
App uses low level Android API (AudioRecorder) for recording sound, files along with metadata are saved in external phone memory.
App contains three activites:
MainActivity - Data is loaded during onCreate, here we've got a choice what do we want to do in App.
RecordingActivity - Allows to record new sounds.
ListActivity - Contains list view with recorded elements, and an options menu, where you can find options like
Concatenate - concatenates two selected files into one first -> second.
Delete - deletes recording from external memory and deletes metadata.
Play - gives possibility to listen to the recording.
Stop
Pause/Unpause
Recording process is done using two threads, which starts when record button is clicked.
Thread 1 - Record - This thread saves sound data blocks into a concurrent queue
Thread 2 - Process - This thread processes the queue, by deleting silent blocks, and writing consecutive byte blocks with audio to a temporal file.
