Multich Record vs Speaker Positioning

Multich Record is a focused multichannel recorder for musicians, bands, podcasts, and field sessions. Use the built-in microphone or a compatible USB audio interface, preview the physical inputs, Arm only what you need, and record every channel as a separate synchronized track. RECORD IN TIME • Set 40–240 BPM, Tap Tempo, 2/4, 3/4, 4/4, or 6/8 • Start with an automatic one-bar visual and audible count-in • Keep the click running through the take and aligned after pause/resume • Click audio is output-only and is never written to original channel files SHAPE WITH CONFIDENCE • Analyze & Recommend runs entirely on device • Detects singing, speech, acoustic instruments, bass, or other material • Suggests 2–3 tested starting points with clear reasons and risk notes • Preview recommendations before applying them to the Draft • Compare Original and FX at matched loudness, then save explicitly • Explore 12 presets across Essentials, Clean, Space, and Color • Fine-tune with musician-friendly controls while preserving every original WAV RECORD, REVIEW & EXPORT • Record with the built-in microphone or compatible multichannel USB interfaces • Arm and record any two physical inputs for free; Multich Pro unlocks 3+ inputs on supported hardware • Review aligned multitrack waveforms and adjust mute, volume, and per-track FX • Export an M4A mix, a WAV mix, or separate channel WAV files • Export original channels or render saved FX, with ZIP packaging for transfer Available input count, sample rate, and bit depth depend on the connected hardware and formats supported by iOS. Subscription pricing and any introductory offer are supplied by the App Store for the current account and storefront.

Find a more useful speaker position by testing one change at a time. Speaker Positioning combines a measured 3D room view with acoustic measurements and a before-and-after comparison. SEE YOUR SETUP Mark both speakers and your listening position with the camera. View the room in 3D, rotate it, zoom in and switch to a top view. Read listening distances, wall clearances and proposed test moves directly in the scene. On a compatible LiDAR iPhone, scan walls, openings and simplified furniture. An optional second pass captures coloured surfaces. Switch between the clean measurement view and room colours. Without LiDAR, define the room footprint manually. PLAN VIRTUALLY Move speakers and the listening position in the model first. A color bass map from 20 to 160 Hz and before-and-after curves show the calculated change. The bass planner assumes a closed rectangular room, uniform damping and ideal speakers. LiDAR captures geometry, not acoustic material properties. SEE MODELS IN AR Overlay calculated wavefronts or a bass map at listening height in the camera view. These AR models are not a measured sound field. Check the actual effect by measuring again and listening. TEST A CHANGE Connect your stereo system, measure at the listening position, then try one change. Measure again with the same volume, microphone position and signal path. Compare the left/right arrival-time difference, both bass-response shapes and changes in position. The app explains when two measurements cannot safely be compared. KEEP THE RESULT Successful measurements and their room views are saved locally. Mark useful results as favorites. Revisit the comparison before deciding whether to keep the change. Speaker-model and subwoofer guidance help you plan further tests. FREE FEATURES • Guided sound, camera and combined workflows • 3D room view with useful dimensions and test positions • LiDAR room and colour capture on supported iPhones • Acoustic measurement, saved results and before-and-after comparison PRO — ONE-TIME PURCHASE • External measurement microphone with calibration-file import • Wired line output and loopback latency calibration • Impulse-response WAV and frequency-response export for REW IMPORTANT Camera dimensions and test positions are approximate. Coloured surfaces are not a photorealistic digital twin; hidden areas, glass and mirrors can leave gaps. Acoustic arrival times can include channel-processing delays. A smaller left/right difference alone does not guarantee better sound. Use repeat measurements and your listening impression to decide. Absolute acoustic distances require a valid latency calibration. An iPhone and a connected stereo system are needed for acoustic assessment. The iPhone-only playback option is a function test. Start at a moderate volume. No account, advertising or tracking. Measurement and room data are processed and saved on your device; you choose whether to share exports.
