3.3. AUDIO TAB :

In this tab, the audio recording is configured.

When the Record Audio option is checked, BSR will record audio from the selected audio source into the video.

3.3.1. Audio Source :

You can select the audio device if you have more than one audio devices. The default one is automatically selected.

Record Audio From :

Speakers (what you hear) : If the sound card installed on the computer contains a channel which will provide audio recording of what is heard from speakers then selecting this option will automatically select the appropriate sound channel required for recording audio heard from speakers. Initially you may need to do the settings once by clicking the Settings For Recording Audio From Speakers button. If such a channel is not supported by the sound card, then see the Solutions section below.

Microphone : If the sound card installed on the computer contains a microphone channel, selecting this option will automatically select the appropriate sound channel required for recording audio from microphone.

Other : The audio recording lines which the sound card installed on that computer supports are listed here. BSR Screen Recorder uses the capabilities of the sound card installed on that computer. You can select any of the audio sources listed. Examples to the input channels are 'microphone', 'line in', 'CD audio', 'What U Hear' etc. If the Speakers (i.e. Stereo Mix, Mono Mix, What U Hear) option is not listed , it means that the sound card doesn't have such an input line. In such a case, see the Solutions section below.

BSR is also capable of changing audio recording line in Windows Vista and Windows 7. If somehow BSR is not able to change audio input line selection, only the selected audio source will be displayed. In that case, for changing the audio source, BSR will open the Windows sound setting window. Starting with Windows Vista, Windows Vista and Windows 7 operating systems doesn't allow programs to change the audio recording sources of the sound cards programmatically. Users must change it manually from the Windows' settings. Therefore BSR opens the Windows Sound setting window and describes to the user how to change it.

If the sound card doesn't support recording audio from speakers then there are 2 alternative solutions :

 

Solution 1:

You can try connecting a cable (3.5mm audio cable with a male plug at each end) from the line-out (or audio out or headphone) port of the computer to the "line-in", and choose the “line-in” as the recording source in BSR. Or if a "line-in" port doesn't exit, you can also connect the cable from the "line-out" (or audio out or headphone) port to the "microphone" port and choose "microphone" as the recording source.

When you connect the cable to the headphone port, you may not be able to hear the computer sound. To solve this, you can connect a 3.5mm splitter to the headphones port to be able to connect both the cable and a headphone.

Solution 2:

You should either install another sound card which supports that feature on your computer or use BSR on another computer which has a capable sound card.

When "Don't allow other applications change audio source during recording" option is checked (not available in Vista & 7), BSR will not allow other applications change audio source during recording. For example when you set recording from Speakers, if the instant messenger tries to change it to microphone BSR will not allow this until the recording ends.

3.3.2. Recording Options :

Record Mouse Click Sounds : When the user clicks mouse while recording, BSR records click sound.

Record Keystroke Sounds : When the user starts typing keyboard during recording, BSR records keystroke sounds in to the video.

3.3.3. Audio Quality :

 

Audio quality settings can be done here. You can select the frequency (kHz), bits (8 or 16) and whether audio will be stereo or mono.

You can also change the audio interleave frequency.

3.3.4. Volume Settings :

Recording volume of the currently selected audio input channel can be set here. For setting all lines you should click the Recording Volumes button.

Warning Levels :

Warn when volume level is lower than : When this option is checked, BSR will warn user if the recording volume of the selected audio source is lower than the specified volume here. (BSR will only warn if the volume control is closed during recording. If it is open, the user will already see and change the recording volume during recording.)

Warn when volume level is higher than : When this option is checked, BSR will warn user if the recording volume of the selected audio source is higher than the specified volume here. (BSR will only warn if the volume control is closed during recording. If it is open, the user will already see and change the recording volume during recording.)

Playback Volumes : For setting the playback volumes, you can click the Playback Volumes button.

Amplify Recording Volume : BSR automatically amplifies the sound volume in selected rate.

Show Volume Control During Recording : BSR opens a volume control on the desktop and the user can set the recording volume during recording with it.

Show Sound Level Meter During Recording : BSR opens a volume level meter which shows the input audio volume during recording.
