Extraction Method	Actual Sound Quality	Cybersecurity Threat Profile	Architectural Transparency
Free Web Converter Sites	Lossy Opus padded into bloated, pseudo-WAV containers	Severe; malicious scripts, intrusive redirects, phishing hooks	Opaque; remote servers execute hidden, unvetted binaries
Third-Party Browser Extensions	Capped at raw source stream limits (160 kbps Opus)	Elevated; risk of silent profile updates and credential theft	Low to Medium; obfuscated code often slips through web stores
Commercial Desktop Rippers	Transcoded MP3, AAC, or WAV; limited to stream source data	Moderate; bundled bloatware, telemetry, upsell nagware	Proprietary; closed-source code with hidden telemetry hooks
Open-Source Tools (yt-dlp)	Direct stream pass-through (demuxing native Opus/M4A)	Extremely Low; zero external ad injection or redirect vectors	High; fully auditable code audited by open-source communities
