Convert AC3 to Lossless WAV Format
Maximum bitrate of 640 kbps limits quality compared to DTS-HD and Dolby TrueHD; strictly lossy with no lossless option. Converting to WAV gives you a key advantage: completely uncompressed pcm audio — the raw digital representation of sound with no processing or quality loss whatsoever. WAV is best for professional audio production, recording studios, and sound design where zero quality loss is mandatory.

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