What is the most important point to remember when recording digital audio?

Room tone is one of the first things you should check when you arrive on set. (But it's also important to keep tabs on it throughout production — especially right before you record.) To combat unnecessary tones in your audio edit, record at least a minute or so of uninterrupted room tone before your shot.

What is the process of recording sound?

Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves.

What is the importance or purpose of audio recording?

Capturing audio with a recorder not only lets you remember life's small details, but improves factual precision–laying the groundwork for accuracy and efficiency in professional, academic, and personal contexts.
