Motorcycle Exhaust and Intake Microphone for best soud on Videos.
Zweikanaliger 24-Bit-Tonrekorder für Motor- und Auspuffgeräusche. Zwei Mikrofonköpfe mit 135 dBSPL Grenzschalldruck an einem Stereo-ADC, aufgezeichnet von einem ESP32-S3 auf microSD — mit Zeitstempeln, die sich im Schnittprogramm von selbst auf das Videomaterial legen.
Gebaut für eine Suzuki Hayabusa: Kopf A am Endrohr, Kopf B in der Airbox.
Alle Kabelstecker sitzen an der oberen Kante und zeigen nach außen, USB-C und microSD liegen rechts hinter einer gemeinsamen Serviceklappe, Leuchtdioden und Taster an der unteren Kante. Auf der Rückseite steht nichts über 2,7 mm — der Aufbau bleibt mit…
