APx500 Audio Analyzers & LabVIEW Software - Audio Precision
https://www.ap.com/analyzers-accessories/apx-overview/labview/
Users can easily integrate the high-quality, robust APx515 analyzer front end into any LabVIEW application involving signal generation and analysis from DC to 90 kHz. Potential uses include vibration analysis, acoustic intensity, ultrasound, infrasound, analysis of dynamic signals (e.g., force, pressure, strain), power supply quality, and more.
Audio analysis in LabVIEW - LabVIEW General - LAVA
https://lavag.org/topic/10580-audio-analysis-in-labview/
Hi, I am fairly new to LabVIEW and require some assistance. I want to be able to play a song and have LabVIEW detect the beat of the song (the lower frequency spectrum) in realtime. Every time a beat is detected, I want LabVIEW to trigger a switch of some sort. Is this possible? Thanks!
