Best Lossless Audio Movies

Lossless audio is bit-for-bit identical to the studio master. Every sample of the original mix is preserved exactly — no perceptual compression, no fidelity tradeoff for bandwidth. Lossy formats (like Dolby Digital, Dolby Digital Plus, and most streaming codecs) discard "inaudible" information to shrink the file, which works well most of the time but can soften texture in cymbal decay, dialogue presence, and quiet ambience. For reference-grade home theater listening, lossless preserves what the engineers heard on the dub stage.

Seven formats we track are lossless: Dolby TrueHD (with or without Atmos), DTS-HD Master Audio, LPCM, DTS:X, Auro-3D, and IMAX. Dolby Digital Plus Atmos is not among them — it carries the same Atmos height layer, but the codec underneath is lossy, so it belongs on our immersive and Dolby Atmos pages rather than this one. Streaming services almost always use lossy codecs to save bandwidth. UHD Blu-ray is the lossless format's native home; standard Blu-ray often includes lossless tracks too, and cinema audio is uncompressed PCM. This page ranks the highest-rated movies on HDIS where the rater used any of these seven formats.

Movie soundtracks have wider dynamic range and more complex sound design than music — there's a quiet conversation, then a thunderclap, then a 30-second silence, then a chorus. Lossy codecs handle the loud moments fine but can soften the quiet, detail-rich ones. Lossless preserves the engineering. On capable gear in a controlled room you can hear the difference in dialogue intelligibility (especially under music), bass articulation, and how cleanly individual layers separate during dense scenes. On a soundbar in a noisy living room, the difference is small.

Mostly no, with rare exceptions. Apple TV's iTunes purchases include lossless on some titles. Kaleidescape (a premium download service) offers lossless. Most major streamers (Netflix, Disney+, Amazon, Max) use lossy Dolby Digital Plus or Dolby Digital Plus Atmos to save bandwidth. The bandwidth math is unforgiving: lossless surround tracks can hit 10+ Mbps; streamers cap audio around 1.5 Mbps. For lossless, the disc — UHD Blu-ray especially — is still the audiophile path. The format column on each rating tells you what version was scored.

Most of them, yes. Lossless audio's natural home is the disc (UHD Blu-ray and standard Blu-ray). A handful of catalog titles are streaming-only or rental-only and may have lossless tracks via specific platforms, but the safest assumption is that any title rated highly on a lossless format here exists on disc. HDIS doesn't track per-platform purchase availability — that data shifts too quickly to keep accurate. The format tag on each rating tells you what the rater played; a title with strong TrueHD or DTS-HD MA scores is a good disc-buy candidate.
