Andromeda brings together a small group of talented software designers.

Our principal consultant, John Heerema, has been involved in just about every aspect of the software industry over the past twenty years, and is a seasoned project manager.

Our long-time industry partnerships and affiliations let us assemble a crack team for a wide variety of software projects—or we can work with your existing team.

We have particular expertise in scientific and real-time applications.

We have developed a suite of software that is targeted to operators of large natural gas pipelines:

• Performance Testing
  Software to measure the power and efficiency of turbocompressors
• Vibration Testing:
  Measuring axial and torsional vibration in rotating equipment
• Flow Computer Testing:
  Systematic validation of electronic flow computers

Our Performance Testing package is used by pipeline operators to measure and track the "as installed" performance of natural gas compressors. It helps them to:

• Get the Maximum Value from Natural Gas compression
• Build operating maps (wheel maps)
• Measure isentropic and polytropic performance
• Measure anti-surge control performance
• Diagnose pipeline conditions which affect flow and compression
• Track ongoing changes to unit performance

• Torsional vibration analysis for rotating machinery
• Measure static and transient torsional vibrations, up to the Shannon limit

Our EFM Test Bench software subjects a flow computer to an endless variety of simulated pipeline conditions. It does this by producing the electrical signals that would be produced by pressure and temperature transducers, and a gas chromatograph. It calculate the exact flow volumes associated with the simulation, letting you determine whether your flow computers are able to accurately measure gas flow under those conditions. Use it to:

• Validate flow computers
• Determine the suitability of a flow computer at meter runs with pulsation, or mixed streams
• Determine whether a gas chromatograph would make a significant difference at a site
• Simulate gas measurement flow runs
• Diagnose flow measurement problems

In addition to our pipeline software consulting, we engage in research into the mathematics of musical signals.

Our music analysis products include:

• Visual Music
  Software that models the neurobiology of the spectrotemporal percpetion of music
• Master Tuner:
  Tune your instrument to historical temperaments, or analyze your vibrato
• Temperament Designer:
  Design your own musical temperaments

Our latest research is about creating tools to let acoustic musicians "see" their performance, an analyze its subtle nuances. It's developing into a teaching system for both individuals and schools, and promises to make practice time dramatically more effective.

Master Tuner was the first software solution for tuning acoustic instruments. Originally developed as a tuning aid for stringed instruments, it was quickly adopted by wind players, who found that its unique ability to show pitch over time, helped them to play their instruments better.

Fifteen years after its original use, it's still being used daily all around the world.

For three centuries, the question of how to split an octave into twelve notes was the subject of intense debate. Not because our current standard, Equal Temperament, hadn't been considered, but because it wasn't considered to be rich enough to showcase the subtle nuances of the music being composed at the time.

There has been an upsurge of interest in both historical temperaments, and microtonal tunings, over the past few years. We developed Temperament Designer to let musicians experiment with their own temperaments.
