This paper presents a comprehensive evaluation of the IETF Opus codec (RFC 6716) across bitrates 32–256 kbps for mono and stereo signals. Using MUSHRA listening tests and objective metrics (PESQ, ViSQOL), Opus is compared against AAC-LC, MP3, and Vorbis. Results show Opus achieves transparency at ≥96 kbps for most music and outperforms other codecs at low latency and low bitrate. No significant difference is found between Opus and source WAV at 192 kbps.
