Compress WAV to AC3 for Smaller File Sizes
Massive file sizes (10 MB per minute at CD quality) make it impractical for streaming or casual sharing. Converting to AC3 gives you a key advantage: industry-standard 5.1 surround sound encoding that every dvd player, blu-ray player, and av receiver decodes natively. AC3 is best for surround sound audio for home theater, dvd, and broadcast television.

Frequently Asked Questions
Will I lose quality converting WAV to AC3?
expand_more
Yes — AC3 uses lossy compression, which discards some data to achieve smaller files. Maximum bitrate of 640 kbps limits quality compared to DTS-HD and Dolby TrueHD; strictly lossy with no lossless option. For most practical purposes at high quality settings, the difference is imperceptible.
How large will my AC3 file be compared to the original WAV?

What's the difference between WAV and AC3?
expand_more
WAV (Waveform Audio File Format) is best for professional audio production, recording studios, and sound design where zero quality loss is mandatory. AC3 (Dolby Digital (AC-3)) is best for surround sound audio for home theater, dvd, and broadcast television. Key tradeoff: WAV's advantage is completely uncompressed pcm audio — the raw digital representation of sound with no processing or quality loss whatsoever, while AC3's advantage is industry-standard 5.1 surround sound encoding that every dvd player, blu-ray player, and av receiver decodes natively.
