Vibration 1.0


Category: Utilities
Price: $0.99 (iTunes)

Description:

Vibration is definitely a program for the iPhone and iPod Touch techno-geek. Vibration turns the iPhone into a powerful (well maybe powerful is too strong a word, but hey, I want to sell programs) vibration spectrum analyzer. All three axes of the internal accelerometer are sampled and plotted on the screen. But wait, there’s more! Vibration also performs a Fourier analysis of the data and and displays the frequency spectrum of all three accelerometers. And for the super geek, you can plot the frequency data in log-linear and log-log format.

All kidding aside, Vibration is a true vibration spectrum analyzer. It acquires and displays time series data, optionally removes DC bias and applies a Hamming window and performs an FFT on each channel to produce the frequency spectrum.

Features:

• Adjustable sample rate from 10Hz to 100Hz
• Selectable data length from 128 to 1024 samples
• Variable start delay from 0 to 20 seconds
• Adjustable vertical scale for both time series and frequency data
• DC Remove option to get rid of that annoying gravity vector
• Switchable Hamming window for frequency analysis
• Frequency data plotted as Linear-Linear, Log-Log, Log-Linear and Linear-Log
• Computes rms vibration for each channel and for all three channels combined
• Document your results by taking screen snapshots and syncing them to your computer
