Abstract [en]

For storage restriction purposes, audio streaming services often rely on lossy compression formats as files used for playback. In 2018, the audio streaming giant SoundCloud went from using 128 kbps MP3 files to 64 kbps Opus files, and shortly after this was unveiled, music press and users of the service claimed it to be an audio quality impairment. To investigate the reliability in these claims, listening tests using popular songs were performed, having 17 trained listeners assessing perceptual audio quality in 128 kbps MP3 and 64 kbps Opus compared to 44.1 kHz, 24 bit WAV files. When counting scores of all used audio stimuli combined, results showed MP3 outperforming Opus with statistical significance.
