RightMark Audio Analyzer test


Testing chain: Sony Xperia T JACK to Xonar Essence ST line-in
Sampling mode: 16 bit samples, 44 kHz

Measurements by supercurio / Francois SIMOND.
Audioflinger and Xperia T Qualcomm audio codec are running at 48KHz on this device but music content and YouTube are at 44.1kHz sample rate hence this choice of sampling rate.
On listening tests, CPU noise is clearly audible which affects the SNR performance.
Due to the random aspect of this kind of noise source the measurements are inherently flawed and non-reproductibles, but you get the idea.
