NEMa - sound note/pitch matrix. App records sound (30sec) and calculate recorded sound spectrum.
Spectrum is calculated and shows as note/pitch matrix or as note/pitch chart.

There are two modes to calculate NEMa:
1) Accurate in this mode range is 0.6% of the base frequency (note frequency);
2) Rough in this mode one note interval goes into another note interval.

The app record audio from C2 note ( 62 Hz) to B7 note ( 3960 Hz).
NEMa contains of 12 notes (C C# D D# E F F# G G# A A# B) and 6 octaves.
Quantization: 16 bit.
Sampling rate: 8000 Hz.

NEMa an easy-to-use app:
1) Press Microphone button to start record;
2) Recording will take 30 sec and when it will show NEM ( note/pitch matrix);
3) Press Chart button to show note pitch chart.

To get more accurate results you need to keep the audio source closer to the phones microphone.

It could help musicians producers composers or beginners in music industry to recognize note pitch amount in played song or sound or recognize which note pitch is played.
