Why 90% of YouTube to MP3 Tools Give You 128kbps When You Asked for 320

Short summary

Most YouTube-to-MP3 tools claim 320kbps but deliver 128kbps because YouTube only serves audio at max 128–160kbps; transcoding can't recover lost quality. The author tested 8 tools, found 7 were misleading, and provides yt-dlp configurations to get genuine maximum quality. Key lesson: show users real source bitrate before download instead of marketing inflated output specs.

• •YouTube's max audio bitrate is 128–160kbps for most content; transcoding to 320kbps doesn't improve source quality
• •7 of 8 tested tools falsely marketed 320kbps downloads despite 128kbps sources
• •yt-dlp with correct format filters (bestaudio[acodec=opus]) + transparent bitrate disclosure solves the problem
