AudioRecord nicht genug Speicher für Audiotrack

Ich versuche, eine Android-Anwendung zu erstellen, die eine Anzahl von X Sekunden und speichert die Datei in .wav FormatAudioRecord nicht genug Speicher für Audiotrack

Das Problem zeichnet ist, dass wenn ich Eingabe mehr als 47 Sekunden (48 und höher) bekomme ich folgende Fehler:

Mein Code arbeitet mit einer beliebigen Anzahl von Sekunden gut, die niedriger als 48 Sekunden ist:
