In addition, I also asked that since it is a comparative test, we should test the validity of the data of the comparative test. Are there many test factors considered consistently?
1. To test the reliability of product samples, at least multiple test samples should be used.
2. The hardware environment of the test, including whether the test instrument has passed the calibration test, whether the tested cables are consistent, whether the test power supply is consistent, and whether the power supply indicators are consistent.
3. The test software environment, including raspberry pie configuration, system version, kernel version, test software version, audio file, since the chip is the same, it also includes whether the configuration registers of sound card are consistent, whether the registers are dump out to compare consistency, driver differences and so on, which all affect the test results. Important factors. Perhaps different filter configurations and different jitter printing configurations will lead to different results.
We all hope that the website can be better and more professional.
