About How Does It Sound
How Does It Sound (HDIS) is a community-driven platform for discovering, rating, and discussing movie sound. It brings together audio ratings, home theater experiences, and conversations to help people find movies they’ll enjoy hearing.
Why HDIS exists
Finding a great Dolby Atmos or DTS:X movie often means searching through forums, articles, and scattered recommendations. There are plenty of opinions, but bringing them together—and understanding which ones relate to your own setup—takes time.
That search inspired Ganesan to create HDIS: one place where listeners can share their perspectives and discover recommendations from the wider community.
Sound is personal. What impresses one listener may feel different to another, especially across different rooms, speakers, and audio formats. HDIS makes those individual experiences the foundation of the platform.
Your movie. Your format. Your home theater.
A rating is more useful when you know the experience behind it. On HDIS, members rate a movie in the audio format they heard and connect that rating to the system they used.
That means the same movie can have different listening experiences across formats and home theaters. Members can explore those differences, read reviews, and understand what stood out—from clear dialogue and powerful bass to convincing overhead effects.
The focus is how the movie sounds, with each listener contributing their own perspective.
How the score works
Every rating is built from up to six sub-ratings, each on a 1.0–10.0 scale: Bass / LFE Impact, Surround Envelopment, Height / Overhead Activity, Dialogue Clarity, Dynamic Range and Sound Design / Creativity. Members fill in the ones their setup can actually judge — someone without height speakers leaves Height blank rather than guessing — and at least one is required.
The overall score is never typed in. The server computes it as the average of whichever sub-ratings the member completed, so every HDIS number is a summary of specific, separately judged qualities rather than a gut-feel star rating.
Why a great mix is not dragged down by a weak track
A movie's headline score uses only the ratings from the highest audio-format tier anyone has rated it in. Formats are ranked by what they can carry — capability, not compression — so an object-based track with a height layer outranks a lossless channel-based one:
| Tier | Formats |
|---|---|
| Tier 4 | Dolby TrueHD Atmos · DTS:X · Dolby Digital Plus Atmos · IMAX · Auro-3D |
| Tier 3 | Dolby TrueHD · DTS-HD Master Audio · LPCM |
| Tier 2 | Dolby Digital Plus · DTS-HD High Resolution |
| Tier 1 | Dolby Digital · DTS |
Lower-tier ratings are not thrown away; they stay visible in each movie's per-format breakdown. They just do not pull an Atmos mix's headline down to the level of its compressed stream. Custom formats added by members count at Tier 1. How to pick the right format when you rate is covered in Ratings & scoring on the Help page.
More than ratings
HDIS is also a place to ask questions, start discussions, and learn from other listeners. Members can find answers, exchange recommendations, share their home theater setups, document their builds, and create movie lists.
Whether you’re looking for your next Atmos movie, exploring a soundtrack’s strengths, or asking the community for advice, those conversations belong here.
Independence
There is no editor's score. Every number on HDIS is computed from member ratings. Some pages carry advertising and affiliate links, which help pay for the site; neither influences any rating, and neither decides which movies appear or how they rank.
Where the data comes from
Movie details — titles, release dates, posters and credits — come from The Movie Database (TMDB). HDIS uses the TMDB API but is not endorsed or certified by TMDB. Every judgement about sound comes from the HDIS community: the formats a movie is available in, the ratings, the reviews and the discussions.
Built around the community
The ratings and recommendations on HDIS come from its members. Every contribution adds another perspective and helps make the platform more useful.
You don’t need an expensive system or technical expertise to participate. An honest account of what you heard—and the setup you heard it on—is valuable.
Independently built by Ganesan Dhakshinamurthy and operated by Akira International LLC, HDIS continues to develop with community feedback. Its purpose remains the same: bring movie sound enthusiasts together and make great listening experiences easier to discover.
