signal processing - Mixing PCM audio samples - Stack …
https://stackoverflow.com/questions/21508372/mixing-pcm-audio-samples
I read that best way to mix multiple audio PCM samples is to take the average of the samples each frame. So if I am adding together say 5 16 bit samples before dividing by 5, there is obviously a good chance it will have a value greater than a 16bit short can hold. So when mixing together multiple 16 bit samples, do I store them all in int first and add them and …
PCM Audio - COMPLETE GUIDE AND REFERENCE
https://planethifi.com/pcm-audio/
PCM audio is used in CD, DVD, Blu-ray, and other digital audio applications. When used in surround sound applications, it is often referred to as Linear PCM audio or Linear Pulse Code Modulation (LPCM). PCM audio produces a series of numbers or digits, and hence this process is called digital. Each one of these digits, though in binary code, represents the …

Re: PCM audio manipulation - volume control and mixing Wednesday, June 01, 2016 7:11 AM ( permalink ) 4 (1) JanJansen. long temp = sample; temp *= volume; // ( 7 bit volume, 0 to 128 ) temp >>= 7; sample = ( short )temp; Unfortunately this gives a Linear volume control, Human hearing works on the log scale.

PCM audio formats Most of digital PCM audio formats ( WAV, FLAC, mp3, AIFF, ALAC, AAC Dolby Digital DTS, Dolby Digital TrueHD, MQA and other) contains musical signal in this PCM format. Audio data may be size compressed to solve issue of: medium capacity or throughput limitation of communication channels (or audio interfaces).
c++ - Trying to mix two PCM audio sources - Stack Overflow

PCM stands for Pulse-Code Modulation, a digital representation of raw analog audio signals. Analog sounds exist as waveforms, and in order to convert a waveform into digital bits, the sound must be sampled and recorded at certain intervals (or pulses).
