What is MP3 Format?
MP3 (MPEG Audio Layer III) is the most popular lossy audio format. It uses perceptual coding to discard audio information that most humans cannot hear, achieving compression ratios of 10:1 or better while maintaining acceptable quality.
Why Generate MP3 Files?

Frequently Asked Questions
What is MP3 format?
MP3 (MPEG Audio Layer III) is a lossy compressed audio format that reduces file size by removing audio frequencies most people cannot hear. It offers a good balance of quality and file size.
What bitrate should I use?
128 kbps is standard for casual listening. 192-256 kbps is good for higher quality. 320 kbps is the maximum and approaches CD quality for most listeners.
How is MP3 different from WAV?
MP3 is compressed (lossy), producing smaller files but with some quality loss. WAV is uncompressed (lossless), preserving perfect quality but with much larger files.
Can MP3 files be edited?
Yes, but each re-encoding introduces additional quality loss. For heavy editing, work with WAV and convert to MP3 only for final distribution.
