Mobile Oscilloscope vs Black Audio Tool

This application turns your phone into a powerful handheld oscilloscope for audio signal analysis (professionals can also use for circuit analysis). The signal parameters can be displayed in detail, including: maximum value, minimum value, average value, effective value and frequency, and the frequency measurement is very accurate. There are multiple trigger modes. The trigger modes are: automatic mode, normal trigger and single trigger; the trigger edges are: rising edge trigger, falling edge trigger, rising or falling edge trigger, jump trigger and differential trigger; the trigger value can be selected. With the measurement function, it is freely measured in the horizontal and vertical directions, gesture operation, easy to use. Waveforms can be freely zoomed with gestures or buttons. Supports interface color selection. Has a storage depth of 10 seconds. This application is normally used for audio signal measurement without any risk. Circuit measurement special instructions: Professionals can use this application for circuit measurements and the electrical signal is input via the microphone channel of the headset. Please pay attention to safety: You must have enough professional knowledge. The high voltage circuit must go through the isolator and attenuator. Conventional low-voltage circuits must also add an attenuator and then enter the phone. Circuit measurement is risky and the author of this application will not be liable for any loss of personnel or equipment resulting from the correct or incorrect use of this application.

Black Audio Tool – B.A.T. Black Audio Tool (B.A.T.) is a powerful and versatile sound-generation app for anyone who enjoys exploring audio. Whether you are an audiophile, sound designer, musician, engineer, or simply curious about the physics of sound, B.A.T. turns your device into a compact laboratory for tone creation, noise shaping, and experimental listening. Create and control a wide range of sounds with precision. Generate classic waveforms such as sine, square, sawtooth, and triangle, then fine-tune them in real time with responsive controls for frequency, tuning, fine tuning, amplitude, and wet/dry mix. B.A.T. goes beyond standard tone generation. Explore interference, layered signal combinations, and a rich collection of noise colors, including white, pink, brown, blue, violet, green, and black noise for everything from soft ambience to unpredictable textures and randomized bursts. To shape your sound even further, B.A.T. includes built-in audio effects such as reverb and distortion, with the option to combine them for more complex and aggressive sonic results. The interface is designed for fast experimentation, precise adjustment, and smooth real-time control. From clean reference tones to abstract soundscapes, from audible frequencies to infra sonic and ultra sonic ranges, B.A.T. is built for discovery, testing, and creative play. Key Features: * Precise waveform generation * Sine, square, sawtooth, and triangle waves * Interference and overlay sound generation * Multiple noise colors, including black noise * Reverb, distortion, and mixed effects * Infra sonic and ultra sonic tone modes * Real-time parameter control * Audio recording to file * AirPlay support Private by Design: * No ads * No in-app purchases * No trackers * No data collection B.A.T. is a focused utility app made for pure sound experimentation — clean, direct, and fully yours.
