WAV to MP3
This lesson is part of Web Developer Tools · All levels
Summary
WAV to MP3 converts large PCM audio to a more compact MP3 with lossy compression. You can choose bitrate; higher values give better quality but larger files. MP3s are perfect for sharing, playing on mobile phones, or uploading to the Internet. Because of the lossy compression, keep the original WAV when you plan on further editing.
Key points
- MP3s use lossy compression so they are much smaller than WAVs.
- 128-192 kbps bitrate common for sharing; 320 kbps for higher quality
- MP3 encoding of WAV is the right step because WAV is still lossless
- The ID3 metadata can be added during or after encoding
- Avoid repeated MP3 encoding from other MP3 files
