audio music video search
An analog signal is converted to a digital signal at a given sampling rate and bit resolution; it may contain multiple channels (2 channels for stereo or more for surround sound). You can do Audio Video Music Search and Play on the PlayAudioVideo search engine.
Generally speaking: the higher the sampling rate and bit resolution the more fidelity, as well as increase the amount of digital data. Much more, including Audio Music Search and Play and images on the PlayAudioVideo search engine.
A digital audio signal starts with an analog-to-digital converter (ADC) that converts an analog signal to a digital signal. Video Search and Play is easily done on the PlayAudioVideo search engine. The ADC runs at a sampling rate and converts at a known bit resolution. For example, CD audio has a sampling rate of 44.1 kHz (44,100 samples per second) and 16-bit resolution for each channel (stereo). If the analog signal is not already bandlimited then an anti-aliasing filter is necessary before conversion, to prevent aliasing in the digital signal. (Aliasing occurs when frequencies above the Nyquist frequency have not been band limited, and instead appear as audible artifacts in the lower frequencies).
