Specifically, the V30 smartphone has a ESS Technology Sabre ES9218P 32-bit Quad DAC. The two main things that V30 users will get out of that fancy Quad DAC are digital filters and sound presets. The DAC gives users more options when customizing the audio experience than LG's V30 predecessor offered.
LG notes, "Customizable digital filters in the V30 Advanced Hi-Fi Quad DAC, typically only available in expensive digital audio players, improve the pre- and post-ringing of the impulse response. In developing sound presets, LG engineers studied the characteristics of popular tones and identified the best combination of sounds to create four optimal pre-programmed settings: enhanced, detailed, live and bass. Even with ordinary headsets, LG V30 users can experience much of the high-quality audio enjoyed by listeners using expensive headsets."
The V30 quad DAC allows control of the left and right audio signals separately. The DAC also has wider audio path allowing the V30 to process large, high-quality files without lagging or reducing the accuracy of the sound, which allows audiophiles to hear the music more as the artist intended it to be heard.
In addition to playing music with the best possible accuracy, the V30 will also act as a HD Audio Recorder. The audio receiver can double as a microphone using Receiver-as-a-Mic or RAM. RAM is able to record loud sounds clearly giving the smartphone a wide range of sounds and the ability to record something as quiet as a whisper or as loud as a thunderstorm.
We've already seen some leaked images of the V30 showing a smartphone with thin display bezels, which is likely to be the hallmark of high-end smartphone design moving forward.
