Humans evolved eating both plant foods and animal foods. By completely eliminating either, we risk becoming deficient in key nutrients. This article lists 7 nutrients that you can not get from commonly consumed plant foods.
PCM redirects here. For other uses, see PCM (disambiguation). Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps.
PCM or LPCM is raw audio, 6 channels of sound, with no coding or compression. Bistream is a term used to refer to the audio when it is read from a disc before it is decoded. Ie. DTS-HD MA bitstream is the same audio as above but has been 'losslessly' compressed. This compressed data is often refered to as the bitstream. If the audio is decoded in the player it is then sent as multi-ch decoded audio ie. LPCM. to the amp / reciever. If the audio is not decoded in the player it is sent as the DTS or DD 'Bitstream' straight from the disc... and then decoded in the reciever / amp.
