What is the difference between MP3 and WAV?
A WAV file normally stores audio uncompressed, so it holds the full recording and takes up a lot of space. An MP3 is compressed by discarding parts of the sound, so it is far smaller but has lost some information permanently. WAV is common in recording and editing; MP3 is common for distribution and listening.
What does bitrate mean in an MP3?
Bitrate is how much data is used per second of audio, usually written in kilobits per second, such as 128 kbps or 320 kbps. A higher bitrate keeps more of the original sound and makes a bigger file; a lower one saves space and discards more.
Is MP3 still used?
Yes, widely, though newer formats such as AAC and Opus achieve similar quality in smaller files and are now the default for many streaming services and devices. MP3 remains common because almost every player made in the last twenty-five years can read it.
