What is the standard sample rate and bit depth for a CD?

The standard sample rate and bit depth for a CD is 44.1 kHz and 16-bit. This specification has been established since the early days of compact discs. The sample rate of 44.1 kHz means that the audio is sampled 44,100 times each second, which effectively captures the frequency range up to about 20 kHz, accommodating the limits of human hearing. The 16-bit depth provides a dynamic range of 96 dB, allowing for a good level of detail and clarity in the audio signal while also keeping file sizes manageable.

This format is widely recognized as the industry standard for audio CDs, ensuring compatibility across various players and systems. Other options presented involve either a higher bit depth or a different sample rate, which are used in different formats or for specific applications but are not applicable to standard audio CDs.
