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 devices including audio ==Screenbits uses general terms for the audio sources which it can capture. The term ''output 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: Output devicesAudio Capture (Audio capture mode)]]

 === 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 audio''' or '''Input audio''' switch on. [[File:RecordingAudio-devicescapture.png|frame|left|Figure 2: Input devicesAudio capture (Screen capture mode)]]

To enable recording == Input mode ==You can choose the input mode for capturing audio from an output input audio device (esuch as a microphone.g. Speakers or system sound)Currently, two input modes are available:#From the [[Getting_started#Application_window|application window]], under ''AudioOpen-mic'' section, click and ''Push-to-talk'Output audio''' button to . In open output -mic mode, the input audio options.#Turn '''Output gets captured continuously while in push-to-talk mode, input audio''' switch gets captured only when the specified push-to-talk key onkeyboard is pressed. You can use push-to-talk mode to capture your voice only when you speak. To change the input mode:

To enable recording an input device (e.g. Microphone):#From the [[Getting_started#Application_window|application window]], under click '''Input audio options'''Audiobutton next to the input audio switch under '' section, click Options''or 'Input audio'Audio'' button section to open input ''Input audio options''.#Turn Select the desired input mode from '''Input audiomode''' switch onselector.

=== Notes ===*You can manually choose a device to record if you want to record a device other than the default device.*Audio [[File:Input-audio-options cannot change while recording is in progress.*More information about output format can be found on [[Output#Audiopng|frame|left|Output Figure 3: Input audiooptions]].<br clear=all>

Screenbits uses system volume settings to record capture audio devices. You can use ''Settings'' app to change volume for output (system sound) and input (microphone) audio:
