Hello. i have over 30GB of Opus music and noticed that solo instrumentals and solo vocals uses more bitrate than full-mixes. Here's example where Opus 1.3 used 190 kbps for piano solo and 159 kbps for full-mix. (--bitrate 160 --music) Download example piano solo 15MB: https://mega.nz/#!wLBz3AZT!YmqQMkAGqc4kGHumNWZAfB7Cmcf4vFlHpT6IiiAVCNA FLAC uses 2 times less bitrate for solo than full-mix because it contain less data, naturally. Hence i think it's a bug in Opus. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.xiph.org/pipermail/opus/a...

Hello. Me again. Have you tried to encode piano solo? Noticed high bitrate Opus gave? And there's also artefact at 15kHz which wasn't in the original audio. Visible with Spek program. Download FLAC and Opus both files, new link: http://www.filedropper.com/example_3 FLAC full: 1084 kbps; FLAC solo: 465 kbps. with --bitrate 160: Opus full: 158 kbps; Opus solo: 190 kbps. Included also Spek
