【實用音樂app】WithStrings Audio Generator|最夯免費app-綠色工廠好玩App

A basic audio generator: adjust shape, frequency, and amplitude.

AudioGenerator streams data to the audio output (music stream) of an Android device using the user selected function, frequency, and amplitude. Wave-forms available are sine, square, and noise. Frequency is selected with multiplier buttons and sliders. Audio output amplitude can be adjusted from 0-100% with the amplitude slider. A numeric readout doubles as a play/pause button. It shows frequency, period, and nearest musical note (based on A=440Hz) for sine and square signals (noise contains an assortment of frequencies).

Instructions

Launch the AudioGenerator application. The initial settings are for a sine wave at 440Hz with a 50% amplitude. The Play/Pause button can be pressed and a 440Hz tone will be generated. Pressing the Play/Pause button again will stop the output. Playing or paused, any slider or button can be adjusted to change the frequency, waveform, or amplitude. Note that audio outputs are AC coupled. The output creates a network with external devices such as ear-buds or amplifiers. The interaction with the devices and internal coupling is evident when a square wave

is selected.
