Digital Portable Audio

The audio measurements below illustrate how accurately the players reproduce the initial/recorded waveform. These devices are tested with both real music and technical signals. Degradation of the waveform is measured with the Difference level parameter (Df, dB). It shows how significantly a final studio mix is altered in a playback device. When the Df level is low (blue area), this implies less deterioration of the sound.

Df-measurements are presented in the form of df-slides - one player per slide. Each slide shows Df levels for ten technical signals and two hours of music [SE test set "Variety"].

How to read df-slides [beta]. How we measure df levels [soon]. What is df-metric.

 

Df-slides below are sorted by histogram median. Top df-slides represent portable players with higher playback fidelity.

Screen of Fame

These innovative and highly-revealing audio measurements became possible thanks to Paul and Maurice from hypethesonics.com and support from audio enthusiasts like you. We plan 100+ devices to test. If you’re able to consider donating, please, specify which player you would like to see in the database. You can also design a personal plate (64x64px) for the screen below. Thank you!
