PCM audio(Pulse-Code Modulation) is one type of digital audio. Ananalog electrical signalfrom a microphone is converted to digital form. In AV-applications PCM is a data-uncompressed alternative to Dolby Digital technology. PCM is representation of an analog acoustic waveform as sequence of samples...

And how is it different from the digital signals used in CDs and every other hi-res music format? Let us explain. Here's everything you need to know about high-resolution audio First, PCM explained... (Image credit: What Hi-Fi?) Digital signals take the form of two states that can ...
WAVE and AIFF are two audio formats that support 44.1 KHz, 16-bit, stereo audio, which is the standard audio specification used by audio CDs. They are also encoded with pulse code modulation (PCM), which is the same encoding used by CD audio tracks. Therefore, WAV and AIF files can be...
CD audio format has a bitrate of 1,411 kbps at 16 bits as an industry standard. High quality WAV file format, AIFF, and PCM files are uncompressed, meaning they include all the audio information, have the same audio bitrate as CDs, and are the largest file sizes. FLAC and ALAC files ...
DSD (SACD) appeared as an improvement to CD-audio. Sound quality is not a DSD/PCM format matter but instead depends on the implementation and quality of a musical recording. “Native” DSD editing is possible for limited cases. For other cases, the losses make it comparable with PCM re-sa...

PortAudio provides samples in raw PCM format. That means each sample is an amplitude to be given to the DAC (digital-to-analog converter) in your sound card. For paInt16, this is a value from -32768 to 32767. For paFloat32, this is a floating-point value from -1.0 to 1.0. The sou...
Pulse-Code Modulation(PCM)is a digital audio file type that represents raw analog signals of the audio. PCM presents sound in waveforms. The waveforms are converted to digital bits through sampling and recording of sound at different intervals or pulses. The converted format features a sampling ra...
All the audio file formats are explained here, but very briefly... DSD, or Direct Stream Digital, is an alternative to PCM and was originally conceived for Super Audio CD (SACDs) – a format championed by Sony and Philips in the late 1990s and into the noughties. It’s a much more ...
