What is the minimum sampling rate for voice?

The minimum recommended sampling rate for voice recording is typically 44.1 kHz (kilohertz). This sampling rate is commonly used in audio production and is the standard for audio CDs. It provides a good balance between audio quality and file size, capturing the nuances of human speech effectively.

While 44.1 kHz is the standard for most applications, higher sampling rates like 48 kHz or 96 kHz are also used in professional audio production. These higher rates can capture more frequency information, which may be important for certain types of audio work, such as music production or sound design. However, for voice recording, 44.1 kHz is generally sufficient and widely accepted.

Using a sampling rate lower than 44.1 kHz can result in a loss of audio quality, particularly in the higher frequencies. Therefore, it's recommended to use a minimum sampling rate of 44.1 kHz for voice recording to ensure that the recorded voice sounds clear and natural.
