Frequently Asked Questions
Q: What is MP3 format?
MP3 (MPEG-1 Audio Layer 3) is the most widely used audio compression format. It can compress files to about 1/10 of their original size while maintaining good sound quality.
Q: What is LAME encoder?
LAME is known as the highest quality MP3 encoder. This tool uses LAME.js, enabling professional-level MP3 conversion quality.
Q: Which bitrate should I choose?
The optimal bitrate depends on your use case:
• 64-96 kbps: Voice/podcasts (about 0.5-0.7 MB/min)
• 128-160 kbps: General music listening (about 1.0-1.2 MB/min)
• 192-256 kbps: High-quality music (about 1.4-1.9 MB/min)
• 320 kbps: Highest quality/archiving (about 2.4 MB/min)
Q: Why does conversion take time?
High-quality MP3 encoding is computationally intensive, especially for large files or high bitrate settings. Since all processing is done in your browser, it also depends on your device performance.
