Input mode
Screenbits can record captures audio from output and input audio devices. You can capture audio either individually in audio capture mode or add it to the captured video when using other [[Capture_mode|capture modes]]. == Input and output audio ==Screenbits uses general terms for the audio sources which it can capture. The term ''output devices including audio'' refers to the audio which is generated by the system and provided to an external device. This is usually the system sound which you can hear from speakers or headphones. In contrast, ''input audio'' refers to the audio generated by an external device, usually a microphone , and speakers (is provided as an input to the system sound)== Audio capture mode ==In audio capture mode, audio devices are the only capture source so the output only contains audio, and [[Recorder|recorder]] produces audio files.#From the application window, click '''Audio''' button under ''Mode'' section.#Under ''Source'' section, enable at least one of the input or audio devices to capture. [[File:Playbackcapture_mode-devicesaudio.png|frame|left|Figure 1: Audio Capture (Audio capture mode)]]<br clear=all> === Notes ===*You can manually choose a specific device to capture rather than the default device. == Other capture modes ==To capture audio in a capture mode other that audio capture mode:#From the [[Getting_started#Application_window|application window]], under ''Options'' section, turn '''Output devicesaudio''' or '''Input audio''' switch on. [[File:Audio-capture.png|frame|left|Figure 2: Audio capture (Screen capture mode)]]<br clear=all> == Input mode ==You can choose the input mode for capturing audio from an input audio device such as a microphone. Currently, two input modes are available: ''Open-mic'' and ''Push-to-talk''. In open-mic mode, the input audio gets captured continuously while in push-to-talk mode, input audio gets captured only when the specified push-to-talk key on keyboard is pressed. You can use push-to-talk mode to capture your voice only when you speak. To change the input mode: #From the [[Getting_started#Application_window|application window]], click '''Input audio options''' button next to the input audio switch under ''Options'' or ''Audio'' section to open ''Input audio options''.#Select the desired input mode from '''Input mode''' selector. [[File:Input-audio-options.png|frame|left|Figure 3: Input audio options]]

 == Volume ==Screenbits uses system volume settings to capture audio devices. You can use ''Settings'' app to change volume for output and input audio:#Click '''Start''' to open ''Start Menu''.#Click '''Settings''' to open ''Settings'' app.#Click '''System''' to open ''System'' settings.#Click '''Sound''' to change sound settings. [[File:RecordingSystem-devicessound-settings.png|frame|left|Figure 14: Input devicesSystem sound settings]]
