Example Scenario:

Suppose you are recording a podcast episode in a home studio. You use a condenser XLR microphone connected to your audio interface via an XLR cable. The balanced connection provided by the XLR cable ensures that the audio signal is clean and free from interference. You position the microphone with a pop filter and adjust the input levels on your audio interface. Throughout the recording session, you monitor the audio to ensure it remains consistent and high-quality. The XLR microphone captures your voice with clarity and detail, resulting in a professional-sounding podcast episode.
