Does converting MP3 to WAV improve audio quality?

No. Converting MP3 to WAV does not restore quality lost during MP3 compression. The WAV file contains exactly the same audio as the MP3, just in an uncompressed container that software can work with more reliably.

Why do some programs require WAV instead of MP3?

Many professional audio and video tools use WAV because it's a simple uncompressed format with no licensing considerations. They avoid MP3 to skip the decoding step and ensure sample-accurate editing.
