- Musician's Spectrum Analyser
- License: Freeware
- Price: 0.00


MSA (Musician's Spectrum Analyser) is a new app for singers and musicians.
Most musical notes are not a single pure sound, but rather a complex mixture of notes called a sound spectrum. The Musician's Spectrum Analyser analyses this spectrum to show
the individual notes that real sounds contain.
MSA displays an ordinary 88-note piano keyboard. It analyses frequencies upto just over 8 kHz, the vertical white line on the far right of the screen shows this frequency.
The yellow trace displays the wave that the MSA is currently analysing. Pressing either the blue or the green Store keys stores this waveform. You can store two spectra. To clear a wave, press Store again when the input is quiet ('storing quietness').
MSA includes a full Help file.

- Nixoid Nixie Clock
- License: Freeware
- Price: 0.00


A clock that shows the time using Nixie tube images. A set of retro toggle switches select US or Euro time/date formats, Keep Screen On, tenths of a second, and full screen mode.
The time shown by Nixoid is made more accurate by correction to the millisecond time received from an NTP (Network Time Protocol) server, if internet is available (this is why the app needs Internet permission).
- Platform: Android 2.x, Android 3.x, Android 4.4, Android 4.x
- SoundForm Signal Generator
- License: Freeware
- Price: 0.00


Soundform generates White and Pink Noise, Sine, Square, Triangle, Ramp waves and Impulses. Uses multiple cycled buffers, refreshed randomly, so ensuring truly random White/Pink noise.

- Vibrations!
- License: Shareware
- Price: 1.49


Vibrations is an app for measuring mechanical vibrations and acoustic noise from engines, the environment, machines, and other equipment.
This is (currently) the only app that combines acoustic *and* mechanical measurements!
Uses: monitoring vehicle engine vibration, monitoring vibrations of household appliances (dishwasher, refrigerator, waste disposal units, clothes dryers, etc.), measuring g-force in moving vehicles, helping to identify failing gears, evidenced by knocking sounds, modes, etc..
Vibrations uses data streams from the built-in accelerometer and microphone: it calculates two simultaneous FFTs, one from the mechanical measurements, one from the audible measurements. It then shows the frequency spectra on the screen. The frequency axis is labelled in Hz and RPM (revolutions per minute).
