WAV (.wav) · Max 20 MB
WAV stores audio without any compression artifacts. Opus uses perceptual coding to reduce file size. The encoder discards audio data it predicts you won't hear.
At 320kbps, most listeners can't distinguish Opus from the lossless source in blind tests. Use the highest bitrate your use case allows.
AudioUtils lets you pick the output bitrate. Choose 320kbps for near-transparent quality. Choose 128kbps for smaller files when size matters more than fidelity.
