    ***I'm looking into translating this App into your language. If you can help me, please email me at and you will be reward with a pro version. Google Translation isn't good enough.

    UltimateAudio Lite is an app that specialized in analyzing the science of sounds. The most advanced sound analyzer available. The app act as a RTA and spectrum analyzer and tone generator. This app combine all my other sound apps into one. What you will get are Spectrum, ActivePinger, ISpectral, Signal Generator, Audio TCP and IGram. If you are an engineer professional, engineering students, oceanographer, bird watching enthusiast, musician, pianist, guitar and speaker tuning, or interested in signal processing.


    A simple spectrum bar graph displaying the frequencies and sound pressure level (SPL) with intensity color-map. This is a simple display and works well on smartwatch like Omate Truesmart.


    ActivePinger is an App that generates acoustic waveform commonly used by sonar (submarine, bat) and displays the results in real-time. Depending on your surrounding environment, you can see the reverberation after pinging. Unlike most Apps, ActivePinger is actually two Apps combined into one: Signal Generator and Spectrogram display. There are six waveform to choose from: Continuous Wave(CW), Coxcomb, Geometric Comb, Costas Waveforms, Pseudorandom waveform(PRNG) and Hyperbolic Frequency Modulation(HFM) waveform. This tool is great for students and professional engineers studying in the field of sound and vibration since you can see the results of the pinging waveform in real-time.


    ISpectral is a fast and accurate real-time FFT analyzer that displays spectral waveform from microphone audio. The app stores a 10 second window history for further in-depth analysis.


    IGram is spectrogram version of ISpectral. With this app you can see a spectrogram longer history.

    Signal Generator:

    Generator signal tone. We will add more features in releases.

    Audio TCP:

    Audio TCP stream data to a client.

    Generator signal tone. We will add more features in releases.

    Now works with Omate Truesmart Smartwatch!!
