MIC (PCM) à haute définition (haut-bit MIC) or MIC (PCM) à haute résolution (haut-bit MIC)
Explanation:
Not sure what went wrong here, but DSD is actually low-bit-count, high-sample rate PCM with noise shaping.
:
Ironically, that means SACD/DSD is going to sound better to you if you CAN'T hear super-high frequencies, because those will be overhyped and noisy, prone to too much energy in the manner of PCM high energy noise shapers. Might be rather exciting sounding, but I think that format would be better suited to darker, more bandlimited recordings. High-bit PCM is more adaptable to different audio content, with fewer 'gotchas'.

To provide direct comparability between CD, SACD and the downloads, stereoplay did not make use of the excellent D/A-converters of the FireFace 400, but instead only used its internal SPDIF-converter. With this high-bit-PCM-signal the reviewers fed a multiplayer from Linn: the Unidisk SC. It is able to play back CD, SACD and the custom-made DVD-Audio and also provides a digital input, which accepts the high resolution digital signal (exception: 88.2 kHz signals are not accepted over the digital input, which Linn confirmed upon request).

Modulation
Sampling and quantization of a signal (red) for 4-bit PCM

In the diagram, a sine wave (red curve) is sampled and quantized for PCM. The sine wave is sampled at regular intervals, shown as vertical lines. For each sample, one of the available values (on the y-axis) is chosen by some algorithm. This produces a fully discrete representation of the input signal (blue points) that can be easily encoded as digital data for storage or manipulation. For the sine wave example at right, we can verify that the quantized values at the sampling moments are 8, 9, 11, 13, 14, 15, 15, 15, 14, etc.
:
The sampling theorem shows PCM devices can operate without introducing distortions within their designed frequency bands if they provide a sampling frequency twice that of the input signal. For example, in telephony, the usable voice frequency band ranges from approximately 300 Hz to 3400 Hz. Therefore, per the Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the voice frequency (4 kHz) for effective reconstruction of the voice signal.
:
Common sample depths for LPCM are 8, 16, 20 or 24 bits per sample.[1][2][3][24]
LPCM encodes a single sound channel. Support for multichannel audio depends on file format and relies on interweaving or synchronization of LPCM streams.[5][25] While two channels (stereo) is the most common format, some can support up to 8 audio channels (7.1 surround).[2][3]
Common sampling frequencies are 48 kHz as used with DVD format videos, or 44.1 kHz as used in Compact discs. Sampling frequencies of 96 kHz or 192 kHz can be used on some newer equipment, with the higher value equating to 6.144 megabit per second for two channels at 16-bit per sample value, but the benefits have been debated.[26] The bitrate limit for LPCM audio on DVD-Video is also 6.144 Mbit/s, allowing 8 channels (7.1 surround) × 48 kHz × 16-bit per sample = 6,144 kbit/s.

signal en Modulation d'impulsion codé à quantification fine/élevée


Explanation:
high-bit pulse code modulated signal
=
pulse code modulated signal with a high number of bits in each sample

i.e. each sample is digitised with (for example) a 16 bit binary number (65,536 levels of sound amplitude) or 12 bit binary numbers (4,096 levels of sound amplitude) instead of a 8 bit binary number (256 levels of sound amplitude)

IOW what is "high" is the number of bits / the resolution on the measurement of the sound level of each sample


Quality and functionality factors Explanation of format description terms
Sound
Fidelity (high audio resolution)

High audio resolution is supported by high sampling rates and high bit-depth (word length). PCM with uncompressed linear quantization is used for digital audio, with a sampling rate of 48kHz currently recommended by the Audio Engineering Society (AES) for the "origination, processing, and interchange of audio programs." 44.1kHz sampling is standard for audio CDs; 96kHz is a recommended sampling frequency for use when higher bandwidth is available, and is generally recommended for preservation reformatting. Telephony applications use non-linear quantization for more efficient use of low bandwidth for speech.

Modulation d'impulsion codée

La modulation par impulsion et codage ou MIC, (en anglais Pulse Code Modulation), généralement abrégé en PCM est une représentation numérique d'un signal électrique résultant d'un processus de numérisation. Le signal est d'abord échantillonné, puis chaque échantillon est quantifié indépendamment des autres échantillons, et chacune des valeurs quantifiées est convertie en un code numérique.
La modulation par impulsion et codage est toujours la première phase de la numérisation d'un signal électrique analogique. Le traitement indépendant de chaque échantillon implique qu'il n'y a ni chiffrement, ni compression de données.
