Yr Xtals vs Speaker Positioning

This started as a tool, and grew into an obsession. Yr Xtals is seriously addictive. I can, and often have, been working on testing it and ended up draining hours just watching the visualizer dance to my music. It's fantastic. I can't imagine if you like music that you won't like this. Especially if you're an audio engineer and are hoping to gain a bit more perspective on your work. That is why I originally made this, and while it has grown into something much larger, it is still a precision audio analysis utility that I know you'll fall in love with, like I have. Enjoy!

The sound of your system is decided by a few centimetres. Speaker Positioning shows you in minutes where your speakers should really stand — measured, not guessed. No expertise required. The app measures your stereo setup with the microphone (sound) and the camera (AR) and turns the result into clear, actionable steps: “The right speaker is 6 cm farther away — equalize it with a tape measure.” No jargon, no tables, no guesswork. WHY IT MATTERS Even small differences in distance and angle shift the soundstage, blur imaging and weaken the bass. Getting your speakers right gets more out of your system than any cable upgrade — for free. HOW IT WORKS 1. Choose how to measure: Sound + Camera (most accurate), Sound only or Camera only. 2. Sit at your listening spot, hold the iPhone at ear height. 3. A short test tone measures both speakers in a single recording. 4. Browse the calm results presentation — as often as you like. WHAT YOU LEARN • Symmetry to the centimetre: is one speaker farther away than the other? • Stereo triangle and toe-in angle in AR — viewable from all sides, with dimensions. • Frequency response and the strongest room mode. • Concrete, actionable move recommendations instead of vague tips. • A speaker catalog: pick your model for placement advice by cabinet/port type. • Subwoofer guidance and a visual mode map showing where the bass builds up. FOR BEGINNERS AND PROS A guided assistant walks beginners through it step by step. If you want detail, you get real measurement tech: impulse response via exponential sweep, frequency response and REW export. PRO (one-time purchase, no subscription) • Support for calibrated measurement microphones (e.g. UMIK-1) for an exact response. • Latency calibration for absolute distances instead of only the difference. • Export of the impulse response as WAV and the frequency response for REW. YOUR DATA STAYS WITH YOU All measurements run locally on the device. No data is collected or transmitted — no account, no cloud, no ads. For stereo setups at home, in the studio, and anywhere sound matters.
