I guess you mean the PCM resampling frequency (If not, let me know)
There are many opinions on Resampling (especially Unsampling), so it seems too difficult for us to say what is good or optimal.
Upsampling 16bit/44.1Khz sound to 192Khz does not restore the information (original sound) that was missed during the first recording.
However, in this process, it would be good to interpret the sound of the lost area as a means of filling in the missing parts so that the sound of the lost area can be heard.
Sounds like overtones that can be mathematically calculated are actually reinforced a little by going through the resampling process.
Some people may have resistance by this processed sound, and in some cases the sound may be distorted like noise from an amplifier or speaker.
In fact, even if playing without resampling, DAC/AMP/Speaker fills these empty areas with their own technologies.
Likewise, Rose also provides the corresponding function to create a pleasing sound by filling in the areas that are lacking in the digital area.
It would be good if you listen to your favorite song while changing the settings to a song that you are familiar with, and choose a comfortable/good sound for you.
For reference, there are many theories and techniques related to resampling.
Among them, we are currently doing resampling using Kaiser window-sinc filter and rectangular dithering.
CPU Resource is limited, so we are using a relatively light method, but we have plans to apply more advanced theories in the future.
Hi, I am a new user of RS201. I found that RS201 "Support for changing output sample rate.
-Set the same output sample rate as the source output and select from 44.1khz to 192khz. (Output change is not affected when playing DSD and MQA.)"
Do I set the output to 192khz will have better performance?
