AKLite Initial release

Sinusoid Pty Ltd announces the initial release of AKLite iPhone App .

AKLite is a real time spectrum analyzer. It is a lite version of the Spectrum part of Audio Kit iPhone App, also by Sinusoid Pty Ltd.

As an introduction to the Audio Kit App, AKLite is free of charge.

FFT Spectrum of AKLite

FFT (Fast Fourier Transform) is used to calculate the frequencies in the Spectrum Analyser and these are displayed in real time. The frequency is displayed in either logarithmic or linear scale.

The area under the line trace can be optionally filled or left blank.

The FFT length used in AKLite is 2048, giving good resolution of frequencies. Interpolation gives resolution to within 1Hz.

A Bartlett FFT window type is used for calculations and there are 3 FFT windows used.

Sinusoid Apps now back on iTunes Store

All Sinusoid iPhone Apps are now back on the iTunes App Store now.


After a few days away from the store due to circumstances beyond our control, the following three Sinusoid iPhone/iOS Apps are again available on the iTunes Store:

Audio Kit

is a collection of four tools which are essential for those working in audio, sound and music; A real time Spectrum Analyzer, a Scope to display waveforms, an SPL Meter, and a Signal Generator producing sine waves, white noise and pink noise. Users can view a real time spectrum of audio, identifying peak frequencies, as well as view the actual waveform of the audio signal and much more.

iPhone Audio Kit update 1.3

The Audio Kit iPhone App from Sinusoid Pty Ltd has a new release, version 1.3.

The first version 1.0 included the following applications:

  • A real time Spectrum Analyser
  • <liScope – an oscilloscope to display waveforms

  • an SPL (sound pressure level) Meter

  • and a sine wave Signal Generator

Since the first release the following features have been added:

  • Signal Generator now includes white noise and pink noise signal types, in addition to the existing sine wave signal.
  • Spectrum display has 6 selectable FFT window function types – Hamming, Hann, Rectangular, Bartlett, Triangular and Blackman.
  • Spectrum now has selectable FFT sizes of 8192, 4096 and 2048, giving much better resolution of frequencies.
  • Persistent settings for all user preferences.
    All of the user preferences in each of the above applications can be made persistent between restarts of the App.
  • Large number display of strongest frequency in Spectrum display. This is in addition to the small moving text above the peak, and can be quickly turned on or off.

Common uses for this App include:


  • checking for feedback frequencies when setting up PA systems

  • an inexpensive oscilloscope to view audio waveforms

  • measuring sound pressure levels

  • providing audio test signals
