1. Autodetects sound – App will only start measuring when a sound is detected. Averaging - After 0. 7s, the app will start averaging the Harmonicity, Jitter, Shimmer and freqency values.
2. Harmonicity is a measure of the sound energy in the harmonics relative to the rest of the spectrum.
3. Whilst lower jitter and shimmer values indicate a purer sound.
4. Jitter is a measure of the frequency variation of the sound.
5. Higher harmonicity values indicate a purer sound.
6. This will continue until the sound is stopped at which point the last 0. 7s of data is removed from the averaged values.
7. The fast fourier transform (size 8192) is performed on the last 0. 74s of data to produce a frequency spectrum (0 to 5. 5 kHz with 1. 35Hz resolution).
8. Shimmer is a measure of the amplitude variation of the sound.
9. Musical Note – The current detected frequency is converted into a note based on western 12 tone equal temperament.
10. Measure the Harmonic to Noise Ratio (Harmonicity) from your microphone.
11. This frequency spectrum is windowed between 100 and 4 kHz with linear fall offs to zero at 50 and 5 kHz.
1. I found it by accident because I'd been searching frequency analyzers for a way to detect the frequency of my instruments.
2. But analyzers are cluttered with controls and options that I don't need and it can be difficult to read the data through the graphs and flashing lights.
3. So if there's no reading, the tone is poor quality or dirty, and best of all, I've found it to be accurate to within 1 Hz.The best app for sound test.Just use this for the fun of it.
4. The app rating system only offers stars but my personal rating is "Hidden treasure."This is so good because it will give you one hz number only.
5. Just a well-detailed app.Okay it worksHarmonicity Meter.Great app1 moreRemoved unnecessary permissions! Awesome! Also an excellent app that does exactly what it claims.
6. I'd been wanting something like this but didn't know it existed so I hadn't been looking.
7. This tool provides exactly what I was looking for in an analyzer and I'll also be able to use it for the functions it was designed for.
8. Good for me looking into chakra healing sounds.
9. It's simple to use, easy to read, and accurate.
10. Good for a simple mind like I have.
11. It will not give a reading at all if the tone is not pure and clean.
