Real Time Audio Spectrum Analyzer with Signal Generator
EasyRTA has fixed 48 kS/s sample rate.
EasyRTA has fixed 8192 FFT points.
EasyRTA has various types of FFT Windowing options, such as: Hann (Hanning), Hamming and Blackman which a user can choose depending on signal types, harmonics spectrum and Signal to Noise Ratio.
EasyRTA has an averaging option to reduce spikes and stochastic flows in the signal. Averaging can be set from 1 (no averaging) to 100 times averaging.
EasyRTA can save measured data to a tab delimited text file, which can later be opened for further viewing and analysis. Also, the saved file is easily imported in applications such as Microsoft Excel. The file contains frequency, amplitude, sample rate and FFT number of points.
