With PCM, the original analogue music waveform is described in two parts. The first is its amplitude (size). In CD this is represented by 16-bits of digital data, which gives us the ability to define 65,536 different signal levels. The original music waveform has to be measured at regular intervals in order for it to be represented properly.
WAV and AIFF are arguably the most popular uncompressed audio file formats, both based on PCM (Pulse Code Modulation), which is widely recognised as the most straightforward audio storage mechanism in the digital domain. Both WAV and AIFF files use similar technology, but store data in slightly different ways.
DSD, or Direct Stream Digital, is an alternative to PCM and was originally conceived for Super Audio CD (SACDs) – a format championed by Sony and Philips in the late 1990s and into the noughties.
The German automotive giant is completely revising its PCM system (Porsche Communication Management) as part of its model year change. And, as part of the update, it’s introducing support for Dolby Atmos audio. The rollout does come with a couple of caveats, though. It will only be available on 911, Taycan, Panamera and Cayenne.
In PCM, you will hear the audio only in stereo, but sending bitstream means your soundbar will be able to receive those lovely Dolby formats, including Atmos. What are the best equaliser setting for a soundbar?
MQA Labs and Lenbrook have further divulged what Qrono is and how it will be implemented moving forward, announcing two technologies within the line. 'Qrono dsd' promises to "set a new standard in DSD-to-PCM converters", whereas 'Qrono d2a' has been designed to "get the best audio performance out of every DAC". According to MQA and Lenbrook, Qrono dsd grants performance enhancement which ...
Topping has unveiled its latest hi-res DAC, the DX5 II. Billed as a compact powerhouse that can also act as a preamplifier and headphone amp, the new unit promises plenty of performance at a price that significantly undercuts some of the best DACs around. The DX5 II's DAC stage is built around twin ...
The PS5 family has since grown. Last year the standard console was joined by the PS5 Slim and PS5 Pro – as the names suggest, the former is more lithe, while the latter packs more power. But whichever PS5 you own, we can help you get the best out of it. Are you really making the most of its 4K 120Hz skills? Enjoying the high dynamic range (HDR) to the fullest? And are you reaping the ...
Optical and HDMI ARC can both carry stereo PCM (uncompressed) and Dolby/DTS 5.1 (compressed), though HDMI e ARC has greater bandwidth and can therefore transmit the next-gen Dolby Atmos and DTS:X surround sound formats. This distinction shouldn't make much difference to how you listen to TV via your stereo active speakers, mind you.
But even if i gave up on the livernois stuff, my understanding is the pcm is now locked with their equipment. So my hptuners supposedly cant touch it. So, my question is this: what are my options for replacing the pcm with a stock calibration for my vin? Is there an online supplier who could write a pcm that I can plug in to work from?
