How long of recorded audio does the Cockpit Voice Recorder provide?

Explanation:
The main concept here is the typical length of audio that a Cockpit Voice Recorder can store. Modern CVRs are designed to capture cockpit communications for a two-hour window. This duration provides a practical balance between having enough recent cockpit audio for investigations and keeping the recorder’s memory requirements reasonable. The recorder continuously logs sound and overwrites the oldest material once the two-hour capacity is reached, ensuring the most recent two hours are always available. While older or specialized systems might use shorter or longer durations, two hours is the standard in most current aircraft.
