\title Spectrum Analyzer
-This application is a demo which uses the QtMultimedia APIs to capture and
-play back PCM audio. While either recording or playback is ongoing, the
-application performs real-time level and frequency spectrum analysis,
-displaying the results in its main window.
+
+ The Spectrum Analyzer demo shows how the \l{QtMultimedia Module} can be
+ used in Qt applications to capture and then play back an audio stream.
+
+ \image spectrum-demo.png
+
+ Because QtMultimedia allows the application to access the raw audio
+ stream, the data can either be inspected or modified by the application.
+ The Spectrum Analyzer demo displays three pieces of information while
+ audio is being either captured or played back:
+
+ \list
+ \o Information about the raw audio stream, shown in the uppermost widget:
+ \list
+ \o The amount of data currently in the buffer, shown in blue
+ \o The segment of data which was most recently analysed to compute
+ the frequency spectrum, shown in green
+ \o The raw audio waveform, shown in white and scrolling from right to
+ left
+ \endlist
+ \o A representation of the frequency spectrum, shown at the lower left
+ \o The current RMS level of the audio stream, and the recent 'high
+ watermark' level, shown at the lower right
+ \endlist
+
+ Spectrum analysis is performed by calculating the Fast Fourier Transform
+ (FFT) of a segment of audio data. An open-source library,
+ \l{http://ldesoras.free.fr/prod.html}{FFTReal}, against which the
+ application is dynamically linked, is used to compute the transform.
