Audio Precision has improved the bandwidth of the FFTs (fast Fourier transforms) in its APx52X audio analyzers from 90 kHz to 1 MHz. The BW52 option provides a frequency resolution of 2.5 Hz at the ...

Marking its 25th anniversary at AES 2009, Audio Precision introduced a new ultra-high-bandwidth analyzer option for the APx525 family of audio analyzers. The new BW52 high-bandwidth option extends its ...

This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...

It’s the end of the semester for [Bruce Land]’s microcontroller design class at Cornell, and the projects coming off the workbench this semester look as awesome as any before. For their final project, ...

I'm looking for anyone that has guides for using FFTs for analyzing audio (via mic), and then for figuring out how best to use that for turning that into RGB LED controls. This is going to be for ...

Audio Precisionreleased the APx517B acoustic analyzer, specifically designed, configured, and built for the production-line testing of speakers, microphones, headphones, headsets, and other consumer ...
