This app provides support for the simultaneous display of "audio waveform" and "amplitude spectrum," which represents the FFT calculation results for each frequency of audio signals received from a microphone. (FFT: Fast Fourier Transform)

Features

  • Simultaneous display of audio waveform and amplitude spectrum
  • Supports both portrait and landscape orientations
  • Configurable display options for audio waveform and amplitude spectrum
  • Selectable FFT sizes
  • Selectable window functions for amplitude spectrum calculation
  • Displays peak level and corresponding frequency of the amplitude spectrum
  • Generates audio signals in four different waveforms
  • Generates noise signals (white noise, pink noise)

Settings

  • Screen Structure:
    • Wave: Displays audio waveform only
    • Spectrum: Displays amplitude spectrum only
    • Vertical: Displays audio waveform and amplitude spectrum vertically
    • Horizontal: Displays audio waveform and amplitude spectrum horizontally
  • FFT Size:
    • Selectable FFT sizes (number of samples used for FFT calculation): 1024, 2048, 4096, 8192
    • Smaller FFT size values result in faster display updates but fewer acquired frequencies in the amplitude spectrum
    • Larger FFT size values result in slower display updates but more acquired frequencies in the amplitude spectrum
  • Window Function:
    • Selectable window functions (used in amplitude spectrum calculation): Hann (Hanning window), Hamm (Hamming window), Blkman (Blackman window), None (No window function)
  • Generate Audio Signal:
    • Generates audio signals in four different waveforms: Sine, Triangle, Square, Saw
    • Frequency can be set between 20Hz and 20000Hz
  • Generate Noise Signal:
    • Generates noise signals: White noise, Pink noise
    • Volume can be adjusted

Other Features

  • Ability to zoom the screen vertically by pinching in/out (Y direction) with a range of 0.5 to 2.0
  • Vertical line spacing in the audio waveform display is set to 2 milliseconds
  • Amplitude spectrum calculation utilizes the vDSP library

If you require support for multiple audio signals, you can try our "Multi Wave Oscillator" app by accessing the link provided on the settings screen of this app. The "Multi Wave Oscillator" app allows you to generate audio signals (Sine, Triangle, Square, Saw) across six channels.
