saimox Player plays spatial audio the way it was mixed โ€” every object in its own place, moving through the room over time. WHAT IT PLAYS ยท SMX packages (.smxd) โ€” streamed from an address or stored on your device ยท SMX works with picture (.smxv) โ€” the sound and the film, side by side ยท Multichannel files up to 9.1.6 and 7.1.4 โ€” WAV, AIFF, multichannel PCM ยท Ordinary files too โ€” MP3, WAV, AIFF, M4A Multichannel files are folded to your headphones through the same HRTF path as an object mix. No downmix to stereo first. Tap an .smxd, an .smxv or a playlist anywhere โ€” Files, Mail, AirDrop โ€” and it opens here. WITH PICTURE A work can carry a film. The sound leads and the picture follows, and the latency of your headphones is measured rather than declared. Turn the phone and the picture turns with it. Works can ship several picture sizes. Pick one by hand, or set a cap for Wi-Fi and another for mobile data. What is playing is read from the file itself, not from its name. SEE THE ROOM The space monitor shows every object where it actually is, moving as the piece plays. Turn it, zoom, or step inside: in head view the camera sits where you sit, and with head tracking the picture turns as you do. Connect a TV or projector and it fills the screen on its own. The phone stays playable and the sound stays wherever you put it, so the picture can go to a projector while the audio goes to a PA. MEASURED, NOT GUESSED Loudness, peak, peak-to-loudness and loudness range for every piece, measured to BS.1770-4 and EBU R128. Set a playback target and pieces are brought to it โ€” quiet ones only as far as their peak allows, so nothing gets squashed by a limiter. The energy curve shows left, right, front, back, up and down over the whole piece, and doubles as the scrubber. FIND THINGS AGAIN Recently played, favourites, recently added, videos, and a row for SMX packages. Open any of them full screen and group by artist. Album, genre, year and credits come from the package and are shown alongside the measurements. BUILT FOR LISTENING ยท Head tracking with compatible headphones ยท Playlists you can share as a file โ€” importing one that already exists asks what to do ยท Download for offline โ€” no buffering, instant seeking ยท Ten colour themes ยท Twenty languages ABOUT SMX SMX is an open format for object-based audio. Instead of a finished mix of channels, a file holds the individual sounds and, for each of them, where it is and how it moves. No ceiling on how many objects a piece may hold. Formats with a fixed maximum โ€” often a hundred and eighteen โ€” force a mix to be reduced before it ships, and no player can undo that reduction later. An SMX package keeps what the mix had. What limits playback is the device, not the format. That is why this app can do what it does. A stereo or surround mix is already decided โ€” the room was baked in when it was made. An SMX package still has the pieces, so it can be rendered for whatever you are listening on, and it can turn with your head, because the positions are still there to turn. Movement is described, not sampled. A sound that circles the room is a few lines saying so, not thousands of coordinates per minute. That keeps packages small enough to stream over mobile data. And it is meant to be reactive: the format reserves a way for objects to respond to something happening while the piece plays. That part is beginning, not finished. The format is free to use. No licence to buy, no per-title fee, no certification to pass, nobody to ask. Write an encoder, ship a player, put SMX in your own product โ€” the specification and the reference implementation are open, and that does not change later. If you make spatial audio yourself, saimox Studio writes SMX and converts to and from all usual delivery formats. And if you build hardware or software, libsaimox does the reading, the positions and the rendering for you โ€” ask us at saimox.com. No accounts. No advertising. No tracking. The app does not phone home.
