Frequently Asked Questions
No — WAV faithfully stores whatever the MP3 contained, compression artifacts included. Convert when a tool requires WAV input, not to gain fidelity.
Uncompressed PCM is trivial to decode and seek, so DAWs, samplers, and some game engines prefer it for editing and low-latency playback.
Roughly 5–10× the MP3's size, since WAV is uncompressed — about 10 MB per minute of stereo audio at CD quality.
Short, frequently-fired SFX (shots, hits, UI clicks) are often kept as WAV/PCM in the engine so they play with zero decode latency; longer music and ambience are better compressed as OGG. Most engines let you set this per-clip — decompress-on-load for SFX, streaming for music.
When a tool in your chain demands it: DAWs, samplers, audio middleware, and some engine importers either require PCM or behave better with it. It's a compatibility conversion — the audio itself neither gains nor loses anything.
