PCMQuellen
PCMQuellen is a term used primarily in German-language discussions of digital audio to denote sources that provide Pulse-Code Modulation (PCM) data. In practice, PCMQuellen can be real-time streams or stored data, and they serve as the input for playback, processing, or analysis in PCM-based workflows. They include devices and formats such as analog-to-digital converters that produce LPCM when an analog signal is sampled, digital audio files in formats such as WAV or AIFF that contain linear PCM data, and network streams delivering PCM payloads in real time for playback.
Key properties of PCMQuellen include sampling rate, bit depth, and number of channels. Common sampling rates
In practice, PCMQuellen are interoperable within PCM-based systems provided that the sampling parameters match end-to-end and
In telecommunications, PCMQuellen often refer to digital trunks employing PCM with mu-law or a-law companding, typically
