If we were to convert dB to a linear scale, 110 dB would be 316,227 and 125 dB would be 1,778,279 – that’s the kind of difference we’re talking about. The Signal to Noise Ratio (SNR) is 125dB (LG), versus 110 dB (competitor) which is a large difference between decibels (dB) are on a logarithmic scale. In any case, there are a few things worth nothing: It wasn’t named, but it looks like the HTC 10 phone’s specs. When we met with the audio team of LG Korea, they pointed out some key differences between them and the closest competitor. Obviously, it is better to have HiFi audio files or audio-source, but even regular audio files can benefit from a better audio system because of noise reduction and up-sampling techniques – to a point. Some high-quality services like Tidal stream audio in The bits per sample represents the maximum amplitude of the recorded signal, or the dynamic range, depending on how the signal is treated. “Precision” or “Fidelity” is mostly defined by three factors at recording and encoding time: the compression scheme, the bits per samples (16/24/32) and the sampling frequency, which defines the resolution of the sound.

It’s a fairly heavy and convoluted way to use a “mobile DAC” (see this $499 “portable” DAC connected to an iPhone)… but the miracles of electronic integration make it possible to embed this kind of capability in a modern handset. Integrating a high-quality DAC in a phone is a relatively new concept, and there are scores of external DAC “boxes” on the market, that could look the one below. If you want to have a little more details about what a DAC is, I recommend following the previous link, but I’ll summarize it here.ĭAC stands for Digital to Analog Converter, and it’s the electronic block/component/module/device that will take the digital audio signal (your digital music file/stream) and convert it into an analog signal that goes to an Amp, then a speaker for listening. There were previous “premium audio” handsets such as the HTC 10 or ZTE Axon 7 which featured improved digital to analog converters (DACs). Smartphones are starting to push further into high-end audio features and this is not something that most people are familiar with. Launched in fanfare in early September 2016, the LG V20 (read our complete LG V20 Review) has the most powerful audio hardware in the smartphone space today.
