App Description
This RTA app supports simultaneous display of "Audio Waveform", as well as the FFT-based "Amplitude Spectrum" (frequency magnitude) and "Spectrogram" (frequency distribution over time), for audio signals input from a microphone.
(FFT: Fast Fourier Transform, RTA: Real Time Analyzer)
[Features]
- Supports simultaneous display of Waveform / Spectrum / Spectrogram.
- Supports orientation both portrait and landscape.
- Selectable configuration of Waveform / Spectrum / Spectrogram display.
- Selectable FFT size.
- Selectable window function.
- Selectable Spectrum Average.
- Selectable frequency weighting. (Flat, dBA, dBC)
- Selectable the type of expressing the X direction (frequency) of Spectrum / Spectrogram. (Linear, Log)
- Displays the peak level and its frequency of the spectrum.
- Peak Hold (displays the results of holding past peak values of the spectrum).
- Octave Analysis (displays the spectrum divided into octave bands).
- Generates the audio signal (Sine, Triangle, Squire, Saw)
- Generates the noise signal (white noise, pink noise)
- Pitch meter display.
[Setting items]
1. Screen structure :
Select the display screen configuration.
View Num : 1, 2
View Type :
- 1 screen : Wave (Waveform) / 1D (Spectrum) / 2D (Spectrogram)
- 2 screens : W+1D (Waveform + Spectrum) / W+2D (Waveform + Spectrogram) / 1D+2D (Spectrum + Spectrogram)
Layout : Vertical (displayed vertically), Horizon (displayed horizontally)
2. Frequency Axis Scale Type :
Selectable the type of expressing the X direction (frequency) of Spectrum / Spectrogram.
- Linear: Distributed at equal intervals
- Log: The intervals increase logarithmically
3. FFT size :
Selectable FFT size. (number of samples used when performing FFT)
1024, 2048, 4096, 8192, 16384
(* 16384 is available in the Pro version.)
4. Window function :
Selectable window function (multiplication just before FFT) used for spectrum calculation.
Hanning, Hamming, Blackman, No window
5. Spectrum Average
Number of spectrum average for a display of spectrum.
1, 2, 4, 8 (init value: 1)
(* 4 and 8 are available in the Pro version.)
Higher value will make the spectrum less noisy and more smooth, at the cost of lower time resolution.
6. Frequency Weighting :
Selectable frequency weighting.
- Flat: No frequency weighting is applied.
- dB(A): Frequency response that takes into account human hearing.
- dB(C): Relatively flat respon
