Description
Deutsch: Zeitfunktionen von Akkorden

Zeitfunktionen und Hüllkurven von Akkorden

|
oberes blaues Diagramm: ||
Zeitfunktion eines c'-dur-Akkords in reiner Stimmung

|- |schwarze Kurven: || Hüllkurven |- |Tonfrequenzen: || 264 Hz (c'), 330 Hz (e'), 396 Hz (g') |- |
|-

|
grünes Diagramm (2.von oben): ||
Zeitfunktion eines c'-dur-Akkords in gleichstufiger Stimmung

|- |schwarze Kurven: || Hüllkurven |- |Tonfrequenzen: || 264 Hz (c'), 330 Hz (e'), 392 Hz (g') |- |
|-

|
gelbes Diagramm (3.von oben): ||
Zeitfunktion eines c'-dur-Akkord bei verringerten Tonschritten

|- |schwarze Kurven: || Hüllkurven |- |Tonfrequenzen: || 264 Hz, 323 Hz, 370 Hz |- |
|-

|
untere rote Kurve: ||
Zeitfunktion einer Dissonanz c'-fis'-h'

|- |schwarze Kurven: || Hüllkurven |- |Tonfrequenzen: || 264 Hz (c'), 370 Hz (fis'), 494 Hz (h')

Methode zur Erzeugung der Kurven
Erzeugung der Zeitfunktionen:

Die Einzeltöne werden als Cosinus-förmige Schwingungen mit jeweils gleicher Amplitude dargestellt und aufsummiert. Verwendete Abtastrate: 4000 Hz

Erzeugung der Hüllkurven:

Innerhalb eines gleitenden Zeitfensters von 15 ms werden die Maxima bzw. Minima der Zeitfunktion gesucht und als Kurve dargestellt.
