Sound Lissajous Meter for Pc

1. For example, when a sine wave with the same frequency as the reference sine wave is reproduced from an audio system, you can observe changes of the frequency or phase in a Lissajous curve pattern.

2. In the case of an unknown sound source, you can analyze the source using the correlation between amplitude, frequency and phase and the reference sine wave.

3. It can be displayed in a two-dimensional curve by Lissajous in the vertical axis as a microphone input signal and the horizontal axis as a reference sine wave.

4. - Mode selection of reference frequency (oct / scale / any) : "oct" - 1/3 octave band (63Hz - 16kHz), "scale" - 12 equal temperament (A3 - A5), "any" - Arbitrary frequency input (100Hz - 10kHz).

5. In addition, it can display Lissajous demo according to changes in frequency and phase.

6. - Reference frequency setting slider - change reference sine wave frequency.

7. - Checking phase of room acoustics or monitoring changes in amplitude, phase and frequency from place to place.

8. - The jitter adjustment can reduce the rotation of the phase angle when Lissajous curve's phase changes sequentially at the same observation position.

9. - The phase θ is valid only when the reference frequency and the measurement frequency are the same.

10. In "any" mode, logarithmic change in reference frequency for 1/2 to 2.

11. "Sound Lissajous Meter" is a new sound analysis app that displays audio signals in Lissajous curves.
