Husker Scope provides an all-in-one cross platform application that implements a Dual Channel (DC) Function Generator, DC AM/FM Modulator, DC Oscilloscope, DC Spectrum Analyzer, and an 8-channel Logic Analyzer. This app outputs audio range (20Hz to 20kHz) signals via the speakers / 3.5mm audio jack left & right channels and inputs signals either through the microphone audio jack (for audio input ranges) or through a custom hardware board (that can handle up to 500kHz signals). The hardware board can connect through serial on a PC or through Bluetooth on a mobile device. For more information and to view the custom hardware board, visit: https://www.huskerscope.com

# GENERATE ANY TONE, FROM 1 HZ TO 40 KHZ Frequency is a tone generator. Set a pitch by hertz or by note and octave, choose a waveform, and play it. It also plays the low sweep that pushes water out of a blocked speaker. # PLAY A TONE AT ANY FREQUENCY Enter a value in hertz, or pick a note and an octave and let the app work it out. The range runs from 1 Hz to 40,000 Hz, past the top of human hearing. # CHOOSE YOUR WAVEFORM Sine, triangle, sawtooth, and square. Each has its own character, and switching between them at the same pitch is the quickest way to hear the difference. # PLAY SEVERAL TONES AT ONCE Run more than one tone together, each with its own frequency, waveform, and volume, and listen to how they interact. # CLEAN YOUR SPEAKER Water trapped in a speaker muffles it. Playing a low-frequency tone at full volume vibrates the driver and pushes the water out — the same technique a smartwatch uses to eject water after a swim. # A REFERENCE PITCH TO TUNE AGAINST Play a note at a known frequency and tune your instrument to it by ear. Frequency plays the reference; it does not listen, so nothing you play reaches the app. # TUTORIALS INCLUDED Step-by-step guides for generating tones, working with waveforms, running several at once, and cleaning a speaker. # SUBSCRIPTIONS AND AUTOMATIC RENEWAL - Your subscription includes access to the features listed above. - Payment will be charged to your Apple ID Account at confirmation of purchase. - Subscription automatically renews unless auto-renewal is turned off at least 24 hours before the end of the current period. - Your account will be charged for renewal within 24 hours prior to the end of your selected subscription period. - Subscriptions can be managed and auto-renewal turned off in your App Store Account Settings. # LEGAL Terms of Service: https://cooptimizeit.com/terms-of-service Privacy Policy: https://cooptimizeit.com/privacy-policy # SUPPORT Contact us at info@cooptimizeit.com.
