Realtime analyzer with recording and Visualizer module with export.
••• Realtime analyzer •••
Realtime analyzer gives you the ability to analyze realtime audio input (built-in microphone or external audio accessory inputs) using Fast Fourier Transform with selected window function. You can also record the input for future offline processing or export.
••• Visualizer •••
This module presents you the results of offline audio analysis. Selecting previously captured recording gives the graph view, spectrogram and waveform of the audio data. Simple controls gives you the ability to play, loop, seek and change rate of the recording synchronized with analysis data presentation. Export function allows you to share or archive your analysis. Resulting PDF document contains basic recording information, spectrogram, peak & RMS graph and frequency table data with maximum peaks (with the time of the occurrence in recording)

App didn’t work right from the start on any device I have. It shows a message that “User have explicitly denied this application the access to the audio/microphone input” and there is no option to switch on the microphone neither on my phone nor the application. I wrote an email to the developer, but they didn’t care to answer. Very disappointed, that’s why 1 star.
