    Size will always be 4096. It means that for a 44100, stereo, 16 bits, sound, this represents +- 23ms, which is more or less 43.5 audio samples per second for, sometime, 24 images per second. Doubling the sample size of PCM would allow the video to always have equally or more of audio ready for encoding.

What is PCM Audio? [Format Difference. Expert Explaned]

    PCM Audio. In basic terms, a PCM audio file is a digital interpretation of an analog sound wave whose goal is to replicate the properties of an analog audio signal as closely as possible to the original source (), called fidelity ().The conversion from analog to digital PCM audio is done through a process called sampling ().In the process of sampling, we will consider …

Pulse-code modulation - Wikipedia

    https://en.wikipedia.org/wiki/Pulse-code_modulation
    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 …
