I want to change realtek's sound format by using command line

aopwaepo32 · 15 Sep 2014

Sound quality is changed by format, so I change the format many times.

When I see a movie, then change to 24 48khz or 192. But many musics are 44.1khz so when I play music, then change to 24 44.1khz.

But that click-work so bother me. So I want change format by command line.

Could you tell me how to control Realtek HD audio manager in command line, plz?

Ex)Realtek HD audio manager - speaker - default format
16 bit 44.1khz <-> 24bit 192khz

If the source is 16 bit, 44.1Khz, changing to 24 bits, 48Khz, etc does not make it sound better. It can only be as good as the source.

I wonder why you would need to keep changing sampling and bit rates though. I just set mine to 24/192 and play whatever files regardless of bit and sampling rate. It won't change the sound of the file.

it doesn't change the file's quality. But in audio manager, different sampling rate makes some bad quality, in my system at least.
It can be shown by RMAA test, and I see the phenomenon in the way.
