Wavelet Voice Sonogram for Android

11 things about Wavelet Voice Sonogram

1. A spectrogram is a graph that shows the results of a sound frequency spectrum analysis with time on the horizontal axis, frequency on the vertical axis, and signal strength in colors.

2. - PCM sound recording and playback is possible up to about 180 seconds, and the audio waveform graph and FFT analysis graph are displayed.

3. "Wavelet Voice Sonogram" is a new sound spectrogram app that performs time-frequency analysis of acoustic signals.

4. This app can perform acoustic analysis and display the spectrograms by using three time-frequency analysis methods, Wavelet analysis, Octave Band analysis, and FFT analysis.

5. - Acoustic analysis can be performed using PCM data recorded with the iPhone's built-in microphone.

6. It is possible to analyze 5 seconds of sound data backward from a user-specified point in time.

7. "Wavelet Voice Sonogram" allows you to easily perform acoustic analysis of speech, instrumental sounds, noise, and more.

8. - The spectrogram analysis result and time axis waveform can be contrasted and played back.

9. - Sound recording and playback, sound waveform and FFT graph display (Main): PCM graph, 10sec zoom graph, FFT graph.

10. - Three types of acoustic analysis, FFT analysis, octave band analysis and wavelet analysis, can be performed simultaneously.

11. - The analysis time varies greatly depending on the performance (generation) of your iPhone.
