Testing with a Microphone
Testing your sound card with a microphone follows these steps
- 1
- Plug the microphone into the appropriate sound card jack. For a Sound
Blaster sound card, this jack is labeled "MIC IN."
- 2
- Record audio data by selecting the Sound Recorder's Record button and
then speak into the microphone. While recording, the green line in the
Sound Recorder should not be flat-lining. If everything has worked, then the
A/D subsystem on your sound card is working properly.
- 3
- After recording the audio data, save it to disk. The data is automatically
saved as a WAV file.
- 4
- Play the saved WAV file. While playing back, the green line in the Sound
Recorder should not be flat-lining. If everything has worked, then the D/A
subsystem on your sound card is working properly.
