c++ - Compressing PCM data - Stack Overflow
https://stackoverflow.com/questions/21817052/compressing-pcm-data
The simplest way is to simply reduce your sample rate from 44100 to something more manageable like 22050, 16000, 11025, or even 8000. Most voice codecs don't go higher than 16000 hz anyway. And the older ones are optimized for 8khz. The next step is to find a codec. There's a handful of codecs to use with the Windows Audio Compression Manager ...
Is PCM audio compressed? - Quora
https://www.quora.com/Is-PCM-audio-compressed
Answer (1 of 2): The term “PCM” is actually a rather general term. However, the standard PCM audio format is lossless and uncompressed. (And, regardless of philosophical arguments about whether any conversion from analog to digital is imperfect, the PCM format is lossless in that none of the dig...
pcm - Dynamic range compression at audio volume ...
https://stackoverflow.com/questions/12665817/dynamic-range-compression-at-audio-volume-normalization
I already asked about audio volume normalization.On most methods (e.g. ReplayGain, which I am most interested in), I might get peaks that exceed the PCM limit (as can also be read here). Simple clipping would probably be the worst thing I can do. As Wikipedia suggests, I should do some form of dynamic range compression.. I am speaking about the …

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 the sampling …

Which Audio File Format . 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).
The Complete Guide to Audio Compression – Icon …
https://iconcollective.edu/audio-compression/
Audio compression reduces the dynamic range of an audio signal. Dynamic range is the difference between the loudest and quietest parts of a waveform. Compression reduces this range by attenuating the louder signals and boosting the quieter signals. As a result, the loudest and softest parts are closer in volume, creating a more balanced sound. ...
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 …
ffmpeg multiplex pcm audio - Compression Techniques ...
https://creativecow.net/forums/thread/ffmpeg-multiplex-pcm-audio/
Hi, I try to multiplex a mpeg2 video with a wav-audio file. The command I use is. ffmpeg.exe -y -i “video.mpg” -f wav -i “audio.wav” -vcodec copy -acodec pcm_s16be “video-mux.mpg”. The multiplex seems to succeed, I can play it with MS Media player, however with a lot of other players (incl Nero and VLC) the sound doesn’t play.
