New range of rotary encoders available from Sinusoid

Sinusoid Pty Ltd has just released new range of its rotary encoders. They offer 10 bit resolution and come in several output formats. These are based on contactless magnetic encoder chips from Austriamicrosystems.

Manufactured in rugged anodised aluminium and built with dual ball bearings they offer high speed continuous rotation up to 7500rpm.

There is a v-ring seal which provides IP50 ingress protection for speeds up to 3000rpm.

New Audio Kit demonstration video

Dailyappshow have just shot a video demonstrating the features of Sinusoid’s Audio Kit app for iOS devices.

See it on the Dailyappshow website or on Youtube.

Audio Kit is now at release version 1.5

The App includes the following tools:

• A real time Spectrum Analyser
• Scope – an oscilloscope to display waveforms
• an SPL (sound pressure level) Meter
• and a sine wave Signal Generator

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 (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 1.4

The Audio Kit iPhone App from Sinusoid Pty Ltd has a new release, version 1.4

The App includes the following tools:

• A real time Spectrum Analyser
• Scope – an oscilloscope to display waveforms
• an SPL (sound pressure level) Meter
• and a sine wave Signal Generator

Audio Kit used in noise measurement

This Norwegian article describes using Audio Kit for the measurement of noise. It describes using the Spectrum Analyser and SPL Meter in the Audio Kit App to measure and discriminate different noise types.
