![]() ![]() However, you need to sample at twice the frequency of the highest sound in the audible spectrum. ![]() This ‘sample rate’ determines to which extent the frequency spectrum is covered. This ‘translation’ happens by taking samples of the analog sound and, if we use standard CD audio quality as an example, the analog sound is sampled 44,100 times per second. In order to convert the analog audio to digital, the voltage information has to be ‘translated’ to a binary code – zeroes and ones. Basically, this is the core of analog sound. ![]() This signal will change amplitude continuously and produce a series of corresponding and fluctuating voltage information. When a microphone captures sound, the mic capsule moves in response to the incoming sound and generates an electric signal. ![]()
