Hello,<br />I've just found that this sample, when encoded with bitrate
lower than about 48 kbps, has got some strange artifacts. According to
that article → <a href="https://people.xiph.org/~jm/opus/opus-1.2/" target="_blank" rel="noopener noreferrer">https://people.xiph.org/~jm/opus/opus-1.2</a>, I should tell
you about it…<br /><br />It sounds like Opus plays high frequencies up and it combines with that echo effect.<br /><br />Best regards<br /> </body>
