He has placed his first five Applications
(Apps) on the iTunes store. All run on the iPad and all but the fourth run on the
iPhone/iPod Touch/iPad.
The fifth (Theremini) turns your device into a miniature Theremin. The original Theremin was a musical instrument which enabled the pitch and volume of a sine wave to be varied as the player's hands were moved close to and away from two antennas. Theramini makes use of the accelerometers for pitch and volume and adds other waveforms, vibrato and a speed of response control. Theramini can be used as a musical instrument, for exploring human hearing ability and as a test oscillator.
The fourth (HarmSyn and the "try it and see" version HarmSyn Lite) allow sounds to be created whose components (harmonics 1-16) can be varied at will as well as the fundamental frequency (f0), volume, vibrato and tremolo. A number of preset sounds can be used via a set of buttons. Compared with the Lite version, the full version has a greater f0 range of 20 Hz to 20 kHz rather than 20 Hz to 1 kHz, a logarithmic or linear f0 controller rather than just linear, 16 rather than 8 harmonic sliders and a greater choice of preset sounds.
The third (Wedding Service Music) is to allow selection of music that can be used at a church wedding during the five key musical moments during the service: Beforehand, at th eentry of the Bride, During the service, at the signing of the Register and for the Exit Processional. There are over 70 pieces of music represented and in each case, a short section of the music can be heard to facilitate making a choice. In addition, each piece of music has a description and the words are listed where appropriate. The App provides a way of helping this special day along with your choice of music for the occasion.
The second (8ve Oscillator
and the "try it and see" version 8ve
Oscillator Lite) is an octave oscillator with
various waveforms (sine, square, pulse, sawtooth, triangular)
available at fundamental frequencies spaced at the octaves
usually used for acoustic and audiological (hearing)
testing (125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz,
8 kHz) as well as white noise. In addition and for interest
it will also include 16 kHz which is generally only
heard by those under about 25 years of age (the so-called
"teen scarer" or "mosquito" sound).
Fundamental frequency can also be set to an arbitrary
value in the range of human hearing (20 Hz to 20 kHz).
Output level can be adjusted in steps of 1, 3, 6, or
10 decibels (dB). The first (Organ Stops)
lists the footages of all manual and pedal pipe organ
stops that can be found on all existing instruments
along with a large selection of stop names - somewhat
anorakish I know - but prepared as a way of finding
out what is involved in creating an App. Bottom C for
each stop footage can be played, including that for
a 128' pedal rank (I know there is no 128' rank in existence
but this is available when a 64' and a 42 2/3' are drawn
together; a so-called "virtual pitch").
