One of the most common misunderstandings is audio quality.

In reality:

• YouTube audio is already compressed (~256 kbps max)
• Converting to MP3 can reduce quality further

👉 Better approach:

• Keep original format (M4A / Opus) when possible

From testing different formats:

• MP3: Best compatibility
• M4A: Better quality at smaller size. (Learn how to transcribe M4A files to text if you work with this format often.)
• Opus: Highest efficiency (less widely supported)

👉 Recommendation:

• Use M4A for best balance
• Use MP3 only if compatibility is required

Many tools become unreliable due to:

• YouTube backend updates
• Legal pressure
• Maintenance issues

This explains why:

👉 “working today” tools often fail later
