Visualize in real-time the frequencies that you can hear around you and even those you cannot. The SpectrumView analyser provides a high quality real-time spectrogram and spectrum analyser display with configurable sample rate and frequency resolution for the iPhone and iPad. You can use this application to measure the highest tones you can sing, to find the source of an annoying sound, for calibrating musical instruments or generally for all sorts of acoustic analysis.Features: High-quality real-time spectrogram view of audio measured with the inbuilt or an external microphone, to observe trends in the frequencies present in the recording environment· Real-time spectrum analyzer that provides a sequence of snapshots of the frequencies present in the recording environment· Multiple selectable sample rates of 8,000 Hz, 11,025 Hz, 16,000 Hz, 22,050 Hz, 24,000 Hz, 32,000 Hz, 44,100 Hz and 48,000 Hz. · Sampling rates of up to 48,000 Hz, for up to 24,000 Hz measurements. · High- frequency resolution with configurable signal analysis window lengths or Fast Fourier Transform (FFT) orders. · Native support for portrait and landscape modes in iPhones and iPads.· Sound intensity represented using a colour spectrum scale from -96 dBFS to 0 dBFS. · Frequency Pinch-to-Zoom. Allows you to zoom in frequency space to look at a specific tone or frequency.· *New* Allows recording and playback of 15 second clips. Clips can then be uploaded to soundcloud and posted to facebook!· *New* Fullscreen mode. Hide the menu at the bottom of the screen to get even more of the screen dedicated to frequency analysis.· *New* Selectable spectrogram colour scales.
