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...

This article is intended to give an overview of how PCM audio is stored and processed on a PC. It also explains the structure of wave files and shows you how to work with them using code written in C++. But, the actual theory behind PCM, such as aliasing and so forth, is beyond the...
A full scale (FS) output will actually be FS-0.5dB. This can be compensated for within the process flow using PurePath Studio. The I2S output can be a separate audio stream to the analog DAC output, allowing 2.1 and 2.2 systems to be implimented. By default, the SDOUT is not linked...
24-bit audio data width. Sampling rates up to 200 kHz are supported. The PCM1681 and PCM1681-Q1 provide a sub-set of user-programmable functions through a parallel control port, in addition to a full set of user-programmable functions through a serial control port, SPI, or I2C. ...
I2S Audio Data Format 31 32 LSB 9.3.2.3 Zero Data Detect The PCM510xA has a zero-data detect function. When the device detects continuous zero data, it enters a full analog mute condition. The PCM510xA counts zero data over 1024 LRCKs (21ms @ 48kHz) before setting analog mute. In ...
(and JRiver and others) show ISO playback as SACD to differentiate it from the same songs in DSF or DFF. As you know, I much prefer DSF (if extracting to separate tracks) as it supports full ID3V2 tagging/metadata. ISO playback, though, is a real winner for those who never really...
Again, you'll hear the richness in the D100. Interestingly, it also captures a more full representation of the spectrum of the water and air spurts, with substantially improved high end. This is also noticeable in the sizzling of the coffee maker track. ...

Part Number: PCM1862 Hi, The full-scale voltage input of PCM1862 is 2.1Vrms ≒ 5.94Vpp at single-ended mode, right? Best Regards, Kuramochi4 年多前 Collin Wells 4 年多前 TI__Guru 63185 points Yes, that is correct. 2.1Vrms * 2 * 1.414 = 5.938Vpp. There is an internal ...
