Theremini for iPhone, iPod Touch, iPad (Home page)
The control of pitch and volume of tones is basic to making music and the Theremin was an early electronic instrument that enabled this by hand gesture. Theremini is a modern version where tilting gestures are used. Challenges are provided with a number of levels of difficulty and high scores are saved. Theremini can also be used to explore the human hearing range and as a test oscillator.

Theremini Lite for iPhone, iPod Touch, iPad (Home page)
A lite version of Theremini which has the full Theremini instrument but does not include the challenges. Pitch and volume are controlled by tilting the device. Vibrato is also available and the pitch and volume ranges can be changed over the full human hearing range. Theremini Lite can also be used to explore the human hearing range and as a test oscillator.

synthesis of harmonics

HarmSyn - Harmonic Synthesis for iPad (Home page)
The ability to create any periodic waveshape by adding harmonics is basic to the synhthesis of sound. The App is for the iPad only, due to the need for plenty of interactive screen space, and it enables harmonic synthesis to be demonstrated for teaching purposes and for fun. Sixteen harmonic sliders are available for hand-editing along with tremolo and vibrato. In addition, there are a number of preset waveshapes that can be called up using selector buttons.

HarmSynLite - Harmonic Synthesis Lite for iPad (Home page)
A Lite free version of Harmonic Synthesis with less control over the synthesis parameters. It has 8 harmonic sliders rather than 16, a linear fundamental frequency slider rather than log or linear, a pitch range of 20Hz to 1000Hz rather than 20Hz to 20000Hz and less preset sounds available compared with the full version. It is intended to whet the appetite and for those who do not require the full feature set.

Wedding Service Music for iPad, iPhone and iPod Touch (Home page)
All the most popular wedding music by title composer and with a short audio file to allow you to check which piece is which (those trumpet tunes can be organised in your mind!).

8ve Oscillator for iPad, iPhone and iPod Touch (Home page)
An oscillator with sine, square, pulse, triangular, sawtooth and noise. Fundamental frequency can be changed (except noise!) in octaves between 125 Hz, and 16 kHz or set to arbitrary values in the hearing range (20 Hz to20 kHz). Useful for acoustic, equipment and hearing testing.

8ve Oscillator Lite for iPad, iPhone and iPod Touch (Home page)
A lite version of 8ve Oscillator sharing all its features except that the fundamental frequency can not be set arbitrarily and its range of octaves is limited to being between 250 Hz and 8 kHz. Useful for acoustic, equipment and hearing testing.


Organ Stops for iPad, iPhone and iPod Touch (Home page)
Shows all footages of all pipe organs stops along with a library of nearly 600 stop names for manuals and over 300 stop names for pedals. Touching the stop knob plays the bottom note for that footage including a 128' pedal stop which has a frequency of 4 Hz (4 times a second) and yes you can hear this on an iPhone/iTouch loudspeaker!
