Ono Sokki's DR-7100 Portable Data Recorder is an excellent solution for in-vehicle sound, vibration, and running speed measurements--and an alternative to traditional digital audio tape (DAT) recording systems. The DR-7100 features 4 input channels for microphone and/or accelerometer sensors and 1 external trigger or tachometer input channel. Data can be analyzed with the Ono Sokki OS-2000 Signal Process Software or exported in UFF format for use in other applications
