Scroll Volume Remote vs Signal Scope Studio

Scroll Volume Remote is the free iPhone companion to Scroll Volume for Mac — a macOS utility that turns the menu bar into a volume target. This app on its own does nothing useful. Its only job is to remotely control the Scroll Volume Mac app from your phone, by acting as a wireless volume wheel. If you do not own and run the Mac app, there is nothing here for you. WHAT IT IS, AND WHAT IT IS NOT This is not a generic "Mac remote" or a universal volume controller. It cannot adjust the volume of a Mac that does not have Scroll Volume installed and running. It cannot control any other application, system setting, or media playback. It cannot connect to anything other than a Mac running Scroll Volume. It is a single-purpose add-on to one specific Mac app. If you have the Mac app: this is a small, free bonus that lets you change your Mac's volume from a few meters away. If you do not have the Mac app: please install it first from the Mac App Store. The Mac app is the product. This app is the remote. HOW IT WORKS WITH SCROLL VOLUME FOR MAC Install Scroll Volume for Mac from the Mac App Store on your Mac. Launch it. Then open this app on your iPhone — it will look for Macs nearby that are running Scroll Volume, and offer to pair with them. Tap to pair. From then on the two devices recognize each other automatically. Spin the wheel on the phone, and the Mac's system volume changes — one notch on the phone, one step on the Mac. Mute and unmute work too. The two devices communicate directly using Apple's MultipeerConnectivity framework over Bluetooth and the local Wi-Fi network. There is no router-only requirement, no internet involved, and no servers in the middle. We do not run any. Traffic stays on your local link. KEY POINTS • Free companion to the Scroll Volume for Mac app — does nothing without it. • Acts as a wireless volume wheel for the paired Mac running Scroll Volume — fluid, one notch per step. • Direct device-to-device link over Bluetooth and local Wi-Fi. No internet. No accounts. No servers. • Pair once, reconnect automatically. The app remembers Macs you have paired with. • Single-purpose. The app does this one thing and nothing else. PRIVACY BY DEFAULT Scroll Volume Remote collects nothing. No accounts, no analytics SDKs, no advertising identifiers, no crash reporting services, no third-party trackers. The only thing the app keeps on disk is the name of Macs you have paired with so it can reconnect. That information never leaves your device. The app runs in the iOS sandbox. PERMISSIONS • Local Network — required so the app can discover your Mac on the same Wi-Fi network. You will be prompted on first launch. • Bluetooth — required so the app can discover and talk to your Mac when there is no shared Wi-Fi network, using Apple's peer-to-peer Bluetooth. REQUIREMENTS iOS 16 or later. A Mac with Scroll Volume for Mac installed and running. The Mac app is sold separately on the Mac App Store and is required — this iPhone app has no use without it. The two devices need to be on the same local Wi-Fi network, or have Bluetooth turned on, to discover each other.

Signal Scope Studio combines a dual-channel oscillator, an output signal simulator, a live microphone oscilloscope and spectrum analyzer, and a stereo decibel meter in one audio toolkit. DUAL SIGNAL GENERATOR • Set sine, square, triangle, falling sawtooth, or white noise independently for LEFT and RIGHT • Adjust frequency from 20 Hz to 20 kHz and volume from 0 to 100% with 270-degree dials. Frequency also supports numeric entry • Adjust left and right frequency and volume independently, or link them while preserving the ratios at the time linking is enabled • Output different frequencies from the left and right channels to produce beats and other effects OUTPUT SIGNAL SIMULATOR • Linearly sum LEFT + RIGHT internally and display the waveform and spectrum together • Adjust Auto Trigger, freeze/resume, vertical and horizontal zoom, and refresh interval • Control frequency range, spectrum sensitivity, and FFT resolution with dials or pinch and pan gestures • Save high-resolution graphs with a dark navy background, white text, and green traces to Photos WAVESCOPE • Display the time-domain waveform and frequency spectrum of microphone input together in real time • Use Auto Trigger, freeze display, pinch zoom, and a movable settings window • Open Dual Signal Generator within the app and measure the actual sound emitted by the same device DECIBEL METER • Display relative microphone input levels on analog-style VU meters in real time • Automatically detect stereo or mono input: two separate meters for the left and right channels in stereo, or one meter in mono • Use PEAK indicators to spot brief sounds near the maximum input level • Save a calibration offset to match a commercial decibel meter MORE • All features are available for seven days from the original download date.
