Easy Audio Spectrogram vs Camper Level Niveau

Easy Audio Spectrogram is a simple real-time audio visualizer for microphone input. It shows live spectrogram and frequency spectrum views, helping you explore voices, instruments, music, room noise, and everyday sounds. The app is built around readability. Instead of adjusting gain values in the blind or fight a fixed color range, Easy Audio Spectrogram lets you adjust the graph’s dynamic range in real time. Use the live spectrum display as a guide, drag the color scale to the range you care about, and instantly get a clearer spectrogram. For music and voice, the app includes a note-based frequency scale and real-time pitch detection, making it easier to see sung notes, instrument pitch, harmonics, and resonance as they happen. The interface is minimal and comfortable to use in any orientation, even upside down. Text and icons rotate, but controls stay where they are, so the app remains easy to use whether the phone is in your hand, on a table, or pointed toward a sound source. You do not have to understand what's an FFT to use this app, the default setting works well and engineering settings have been translated to understandable concepts. You can save clean spectrogram screenshots directly from the app, without the buttons covering the image and without pressing hardware button combinations. This app is free to use, free of pop-ups or advertisement banners, use it to explore music or the science of acoustics. Additional Features: -Noise profile removal, hold the button to record a profile, release to activate. -Analyze harmonics in real time with multi-touch. -Psychoacoustic filter to make the graph reflect perceived sound signature rather than flat physical reality. -Optimized performance for many hours of use without heating up your device or draining the battery.

Camper Level Niveau – the talking spirit level for your RV No more getting out, checking the bubble, getting back in: Camper Level Niveau tells you out loud how your motorhome sits while you manoeuvre – for example “2 degrees right, 3 degrees front”. You stay at the wheel, drive forward or back, place your leveling blocks – until the app says “Level”. HOW IT WORKS 1. Lay your iPhone flat on the table and clamp it in place (the camera bump may hang over the edge). 2. Tap the speaker button. 3. Drive. Every 6 seconds (adjustable from 2 to 30 s) you hear the current tilt to the left, right, front or back. NO CALIBRATION REQUIRED Camper Level Niveau measures true level using your iPhone’s motion sensor. Nothing to zero, nothing to tare. Just tell the app once whether the camera points forward, left, right or backward – done. A LEVEL YOU CAN SEE – AND HEAR The display is a classic bull’s-eye bubble level: black background, green rings for every degree, a green ball that rolls to the lower side. Below it you see side and lengthwise tilt to one decimal place. When everything is within tolerance, the ball glows bright. FEATURES • Voice announcements – just four words: left, right, front, back • Announcement interval adjustable (2–30 seconds) • Adjustable “level” tolerance (e.g. 0.5°) • Scale from 3° to 15° • iPhone orientation on the table freely selectable • Screen stays on while leveling • English and German • No data collection, no account, no ads – works completely offline WHO IS IT FOR? • Motorhomes, RVs, campervans, Class A/B/C, coachbuilt, panel vans • Caravans and travel trailers when setting up with a mover • Truck campers, roof tents, overland and expedition vehicles • Solo travellers who have no one to guide them in WHY LEVEL AT ALL? An absorption fridge only cools properly when level. Shower and sink only drain when the vehicle sits straight. And sleeping head-down gives you a headache. With Camper Level Niveau you find the right spot on any pitch, campground or field in about a minute. Made by myn.to – by campers, for campers. Questions, ideas, bugs?
