Rob Hensley’s Audio Scope (App Store link) is a $.99 iPhone app that uses the remote i/o audio unit for handling audio input and output.
The application can display the input audio in one of the forms, a regular time domain waveform, a frequency domain waveform (computed by performing a fast fourier transform on the incoming signal), and a sonogram view (a view displaying the frequency content of a signal over time, with the color signaling relative power, the y axis being frequency and the x as time).
Tap the sono button to switch to a sonogram view, tap anywhere on the screen to return to the oscilloscope. Tap the FFT button to perform and display the input data after an FFT transform. Pinch in the oscilloscope view to expand and contract the scale for the x axis.

Macbook Video DRM Problems Continue to Make Waves
Apple continues to find itself in hot water over its decision to support strict copy protection standards with its new line of Macbooks. Owners of the new generation of Macbooks and Macbook Pros were up in arms last week about the fact that HD movies bought at the iTunes store wouldn’t show up on many external displays, such as LCD screens or digital projectors. Instead, users were greeted by a warning that their displays were “not authorized to play protected movies.”
Apple reacted to the brouhaha this week with a Quicktime update that disabled the copy protection scheme. That apparently wasn’t enough to appease the Free Software Foundation (FSF). The open source advocacy organization just started a holiday-themed “35 Days against DRM” campaign that attempts to point out flaws of consumer electronics with DRM support and dissuade shoppers from buying them, one device a day. Think of it as an advent calendar from the Church of Linux, if you will. Apple’s new Macbooks have the dubious honor of being featured on the campaign’s very first day.
