        Measure the frequency of a single tone.

        This experiment records audio from the microphone and analyses it for its frequency. This only works if there is a single tone with a fixed frequency - if there are multiple frequencies (like an accord), use the "spectrum" experiment instead.

        The analysis is done by calculating the autocorrelation of the audio signal. The experiment then considers all peaks that exceed half of the maximum signal in the autocorrelation. The position of the last of these peaks within the autocorrelation gives a multiple of the period of the signal. By counting the number of peaks we can get the period of the base frequency.

        Die Frequenz eines einzelnen Tons ermitteln.

                Dieses Experiment nimmt über das Mikrofon Töne auf und ermittelt ihre Frequenz. Dies funktioniert nur wenn es sich dabei um einen einzigen Ton mit fester Frequenz handelt - Wenn du mehrere Frequenzen (wie in einem Akkord) analysieren möchtest, verwende statt dessen das Experiment "Audio Spektrum".

                Die Frequenz wird mittels einer Autokorrelation des Audiosignals ermittelt. Das Experiment sucht alle Maxima im Korrelationssignal heraus, die die Hälfte des globalen Maximums überschreiten. Die Position des letzten Maximums in der Autokorrelation entspricht dem Vielfachen der gesuchten Periode, die wir durch Abzählen der Maxima ermitteln können.

        Měření frekvence tónu.

Tento experiment analyzuje frekvenci zvukového záznamu z mikrofonu. To ovšem funguje pouze v tom případě, že je zaznamenán jeden tón s konstantní frekvencí. Chcete-li analyzovat několik tónů současně (např. akord), pak použijte experiment "spektrum".

Analýza je provedena pomocí výpočtu autokorelace zvukového signálu. Experiment pak vyhodnotí všechny špičky, které přesáhnou o víc jak půlku maximálního signálu z autokorelace. Pozice poslední z těchto špiček v autokorelaci udává násobek periody signálu. Spočítáním počtu špiček pak můžeme získat periodu základní frekvence.

        Wyznacz częstotliwość tonu.

        W tym eksperymencie rejestrowany jest dźwięk i określana jest jego częstotliwość. Eksperyment przeznaczony jest wyłącznie do analizy tonów. W przypadku analizy dźwięków złożonych (np. akordów) zaleca się korzystanie z eksperymentu 'Widmo audio'.

        Analiza prowadzona jest w oparciu o procedurę autokorelacji sygnału dźwiękowego. W korelacji uwzględniane są wszystkie maksima sygnału o amplitudzie przekraczającej połowę rejestrowanej wartości maksymalnej. Położenie w czasie ostatniego z analizowanych maksimów odpowiada wielokrotności okresu i na podstawie informacji o liczbie okresów wyznaczana jest częstotliwość rejestrowanego sygnału dźwiękowego.

        Meet de frequentie van een enkele toon.

        In dit experiment wordt een audiosignaal via de microfoon opgenomen en zijn frequentie berekend. Dit werkt alleen als er één toon met een vaste frequentie is - als er meerdere frequenties zijn (zoals een akkoord), gebruik dan het "spectrum"-experiment.

        De analyse wordt uitgevoerd door de autocorrelatie van het audiosignaal te berekenen. Het experiment bestudeert vervolgens alle pieken die in de autocorrelatie de helft van het maximale signaal overschrijden. De positie van de laatste van deze pieken binnen de autocorrelatie geeft een veelvoud van de periode van het signaal. Door het aantal pieken te tellen, kunnen we de periode van de basisfrequentie krijgen.

        Misura la frequenza di un singolo tono

Questo esperimento registra un segnale audio attraverso il microfono e ne analizza la frequenza. Funziona solo se vi è un singolo tono con una frequenza fissa - per analizzare un segnale con più frequenze (es. un accordo), usare l’esperimento “Spettro”.

L’analisi viene effettuata calcolando l’auto-correlazione del segnale audio. Il sistema considera tutti i picchi di altezza maggiore di metà del massimo segnale nello spettro di autocorrelazione. La posizione dell'ultimo di questo picchi fornisce un multiplo del periodo del segnale. Contando il numero di picchi si ottiene il periodo della frequenza di base.

        Μέτρηση της συχνότητας ενός μοναδικού τόνου.

Στο πείραμα καταγράφεται ήχος από το μικρόφωνο και αναλύεται η συχνότητά του. Αυτό λειτουργεί μόνο αν είναι ένας τόνος με συγκεκριμένη συχνότητα - αν υπάρχουν περισσότερες συχνότητας (όπως μια συγχορδία), χρησιμοποιήστε εναλλακτικά το πείραμα του ηχητικού φάσματος.

Η ανάλυση γίνεται με τον υπολογισμό της αυτοσυσχέτισης του ηχητικού σήματος. Στη συνέχεια βρίσκονται οι κορυφές που ξεπερνούν το μισό του μέγιστου σήματος της αυτοσυσχέτισης. Η θέση των τελευταίων από αυτές τις κορυφές μέσα στην αυτοσυσχέτιση  είναι πολλαπλάσιο της περιόδου του σήματος. Μετρώντας το πλήθος των κορυφών μπορούμε να βρούμε την περίοδο της βασικής συχνότητας

        単一音の周波数測定．

本実験はマイクから音を録音し，その周波数を解析します．一定周波数の単一音源の場合においてのみ，本実験は期待した動作をします．もし和音のように複数の周波数が含まれる場合，音響スペクトル の実験を使用してください．

解析は音声信号の自己相関計算から行われます．本実験は，自己相関の最大ピーク値の半分を超えたピークを考慮し，周波数解析に用います．信号強度が十分な最後の自己相関ピークの位置は，信号周期の整数（n）倍を示します．最終自己相関ピークの番号(n)を数えることで，信号の正確な周期が得られます．

        Mede a frequência de um tom único.

        Este experimento grava o som do microfone e analisa-o pela sua frequência. Ele só funciona se houver apenas um tom com uma frequência fixa - se houver múltiplas frequências (como um acorde), use o experimento "Espectro". 

        A análise é feita pelo cálculo da autocorrelação do sinal de som. O experimento então considera todos os picos que ultrapassem a metade do sinal máximo na autocorrelação. A posição do último destes picos dentro da autocorrelação dá um múltiplo do período do sinal. Contando o número de picos, podemos obter o período da frequência de base.

        Bu deney mikrofondan sesi kaydeder ve frekans için analiz eder. Sadece sabit frekansta tek bir ton varsa çalışır eğer birden fazla frekans varsa (bir akort gibi), bunun yerine "spektrum" deneyini kullanın.

        Analiz ses sinyalinin otokorelasyonu hesaplanarak yapılır. Deney daha sonra otokorelasyonda maksimum sinyalin yarısını geçen tüm tepe noktalarını dikkate alır. Otokorelasyon içindeki son tepe noktalarının konumu, sinyalin periyodunun bir çoğunu verir. Tepelerin sayısını hesaplayarak baz frekansının periyodunu alabiliriz.

        Mesurer la fréquence d'une note unique.

         Cette expérience enregistre un son et détermine sa fréquence. Cela ne fonctionne que si le son ne contient qu'une seule note - s'il y a plusieurs fréquences dans le son (comme dans un accord), utilisez plutôt l'expérience "spectre audio".

         L'analyse est effectuée en calculant l'autocorrélation du signal audio. L'analyse tient compte des pics dépassant la moitié du signal maximum dans l'autocorrélation. La position du dernier de ces pics donne un multiple de la période du signal. En comptant le nombre de pics on peut obtenir la période de la fréquence de base.

        Đo tần số của một âm đơn.

        Thí nghiệm này ghi lại âm thanh từ micrô và phân tích tần số của nó. Thí nghiệm này chỉ hoạt động tốt nếu có một âm đơn với tần số cố định - nếu có nhiều tần số, hãy sử dụng thí nghiệm "phổ âm thanh".

        Việc phân tích được thực hiện bằng cách tính toán tương quan tín hiệu âm thanh. Thí nghiệm sau đó xem xét tất cả các đỉnh vượt quá một nửa tín hiệu tối đa trong tự tương quan. Vị trí của các đỉnh cuối cùng trong phạm vi tự tương quan sẽ cho nhiều chu kỳ của tín hiệu. Bằng cách đếm số lượng đỉnh chúng ta có thể có được chu kỳ của tần số cơ sở.

यह प्रयोग आपके माइक्रोफ़ोन से ऑडियो रिकॉर्ड करता है और इसकी आवृत्ति के लिए इसका विश्लेषण करता है। यह केवल तभी काम करेगा जब एक नियत आवृत्ति वाला एक स्वर होता है - यदि कई आवृतियां हैं, तो इसके बजाय "स्पेक्ट्रम" प्रयोग का उपयोग करें।

ऑडियो सिगनल के स्वत: सहसंबंध (ऑटो को-रिलेशन) की गणना करके इसका विश्लेषण किया जाता है। फिर प्रयोग में उन सभी शिखरों पर विचार किया जाता है जो स्वत: सहसंबंध में अधिकतम मान के आधे से अधिक हैं। स्वत: सहसंबंध के भीतर, इन शिखरों में से अंतिम की स्थिति सिगनल के आवर्तकाल का एक गुणज देती है। शिखरों की संख्या की गिनती करके हम मूल आवृत्ति के लिए आवर्तकाल प्राप्त कर सकते हैं|
