| + | Am folosit ca mediu de dezvoltare arduino IDE. Inregistrarea audio o fac la o frecventa de sampling de 40000Hz cu 128 de sampleuri (atat de putin datorita memoriei dinamice reduse a arduinoului).\\ | ||
| + | Pentru prelucrarea sunetului preluat ma folosesc de libraria standard arduinoFFT. | ||

| + | Am obtinut un analizator de spectru care ofera rezultate cu o precizie surprinzator de buna. | ||
