Format guide
What is WAV?
Waveform Audio File Format is a RIFF audio container usually holding uncompressed PCM audio, created by Microsoft / IBM (1991). WAV is the editing and archival workhorse for uncompressed sound. Studios bounce to WAV for quality; convert to MP3, AAC, or OGG when you need downloads, streaming, or chat-friendly sizes.

WAV compression & quality
WAV compression: codec-dependent. Lossy encoding discards some information to shrink files — re-saving repeatedly can accumulate artifacts. Typical size profile: About 10 MB per minute for stereo 16-bit 44.1 kHz. Quality note: Lossless PCM when uncompressed — full fidelity
Quality: Lossless PCM when uncompressed — full fidelity
Typical size: About 10 MB per minute for stereo 16-bit 44.1 kHz
Transparency & animation
