SCIENTIFIC PRECISION TIPS

01
Use identical seeds for reproducible scientific measurements across test sessions
02
Monitor filter rolloff to ensure clean frequency boundaries for critical applications
03
Set sample rate to 2.5x highest frequency to avoid aliasing artifacts
04
Use narrow bands (1-2 octaves) for precise frequency response testing
05
Calibrate amplitude levels using RMS measurements for consistent power
06
Enable stereo mode for spatial audio testing and phase coherence studies
07
Use 96kHz sample rate for ultrasonic testing and extended frequency analysis
08
Combine with spectrum analyzer for real-time frequency response verification
