Recommendation on Hi-Res Audio upsampling settings

The Hi-Res Audio player software plays an important role when one trying to archive the best sounding experience. It is often a muddy business to setup things right. Here we present our recommended condition for our customer to save some time. 1. Audirvana First order of business, make sure upsampling is enabled. Under upsampling panel: 2. Foobar2000 Under DSD Processor Settings Panel, set up the output and SDM type so that PCM audio stream can be upsampled to DSD before sending to the DAC.

Side Note: Why we based many our products on Analog Discovery 

Digilent Analog Discovery is a series of devices that being sold by Digilent. Digilent was bought by National Instrument many years ago, and again, bought by Emerson. It was originally marketed as a device meant for Electronics Engineering Student with subsidies from Analog Devices and Xilinx. The original Analog Discovery (the black one) was sold at $99 to students. The founder of SpecialtyCircuits used it when he was fighting to learn Verilog. Although that battle failed in 2012, but the founder learnt the capacities of it. Later, Digilent released many more updated versions, Analog Discovery 2, Analog Discovery 3, Analog…

Something about analog oscilloscope

Jim Williams once wrote quite some about the benefits of analog oscilloscope. Considering digital oscilloscope also evolved quite a bit since he passed away more 10 years ago, some of the claim may not be true anymore. Nevertheless, here are a few cases, analog scopes show their benefits. 1. Difference of 1.000MHz vs 1.001MHz generated by 40MSPS DAC. The below two screenshots showed some clear distinction between the two signals, which would be quite hard to acquire from modern digital oscilloscopes. The left one shows the peak of a 8Vpp 1.0001 MHz sine wave, the right one shows a 8Vpp…
