PCM and WAV both format contains raw PCM data, the only difference is their header(wav contains a header where pcm doesn't). ... Just get the PCM data and add the wav header on top of the PCM data.

Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. ... 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.

Windows Media Audio or WMA is a recent file format that was created by Microsoft as the default for their media applications. WAV is simply a shortened version of WAVE. It uses the PCM encoding method that is also used by audio CDs. ... Although WAV is also capable of storing compressed audio, it is rarely used as such.

The RIFF format acts as a "wrapper" for various audio coding formats. Though a WAV file can contain compressed audio, the most common WAV audio format is uncompressed audio in the linear pulse code modulation (LPCM) format.

Uncompressed audio: This is an audio file that has no compression applied to it. The sound in uncompressed audio files remains the same as when it was recorded. Examples include PCM, AIFF and WAV formats.

So if you're getting a Dolby Digital signal, and it's not cutting out, your optical cable is fine. If you're transmitting PCM, the audiophile answer is that different optical cables can cause different amounts of jitter. The reality is, the digital-to-analog converter in your gear has vastly more effect on the sound.

Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts.

So PVM is nothing but a software/interpreter that converts the byte code to machine code for given operating system. PVM is also called Python Interpreter and this is the reason Python is called an Interpreted language. ... pyc files are given with PVM so that users can see the output directly.

So compared to a 24-bit WAV file, the 32-bit float WAV file has 770 dB more headroom. ... Each audio sample for 32-bit float files consumes 32 bits of space on a hard disk or memory, and for a 48 kHz sampling rate, this means that 32 x 48,000 = 1,536,000 bits per second are needed for 32-bit, 48 kHz files.

WebM is an open, royalty-free, media file format designed for the web. WebM defines the file container structure, video and audio formats. WebM files consist of video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with the Vorbis or Opus audio codecs.

Depending on the amount of data discarded you may or may not notice the difference, but there is one. The audio quality of WAV and ALAC is identical, but ALAC is both smaller and more versatile since you can add a tag.

Most standard DVDs are MPEG-2 format discs. Home DVD players will also commonly play AC-3 or PCM audio CDS. MPEG-2 is also called H. 222 or H.

Both PCM and DPCM techniques suffer quantization error and distortion but in different extent. DPCM requires less bandwidth while PCM works on higher bandwidth. ... On the contrary, PCM has a better signal-to-noise ratio. PCM is used in audio, video and telephony applications.

Audio CDs always contain uncompressed PCM stereo audio at 44100 Hz sample rate, 16-bit sample format. So to burn an audio CD, export the file(s) you want to burn as a 44100 Hz 16-bit stereo WAV or AIFF file.

PulseAudio Volume Control (pavucontrol) is a simple GTK based volume control tool ("mixer") for the PulseAudio sound server. In contrast to classic mixer tools this one allows you to control both the volume of hardware devices and of each playback stream separately.
