Steam Property- PRO

THIS IS A PROFESSIONNAL APP, even it is free. Allows much more calculation cases than any other free app (and even pay one).
Each calculation is made with high precision, even close to the critical point and high pressure, as major professionnal app.

This app allow to calculate thermodynamic steam properties of steam and/or water, with following inputs:
=> Pressure + Temperature
=> Pressure + Enthalpy
=> Pressure + Entropy
=> Pressure + Volume
=> Temperature + Volume
=> Temperature + Entropy
=> Enthalpy + Entropy

And, for calculation at saturation:
=> Quality + Pressure
=> Quality + Temperature
=> Quality + Volume
=> Temperature only
=> Pressure only

So, this App offers much more calculation than any other free App available on the Play store.
When changing the input property, this App enters automatically the value of this property, using the last result. So, you can simulate several transformations.
As an example, for a flash of saturated water at 3 bar(a) -> 1bar(a):
-> choose calculation at saturation
-> choose 0% as quality and 3 bar(a) as pressure
-> calculate
-> uncheck calculation at saturation
-> choose Pressure and Enthalpy as input data
-> enthalpy value is entered automatically
-> choose 1 bar(a)
-> calculate

A lot of transformations are possible in this way (flash, expansion, boiler, …)

Note Recognition – Convert Music into Sheet Music

“Note Recognition & Audio Speed Changer – Convert Music into Sheet Music” is a note detection & audio speed changer app that converts music into an alternative sheet music. It helps you learning new songs by displaying sheet music suggestions for the recorded audio and provides you the functionality to change the audio speed and slow down your recorded music (“audio slow motion”). It’s perfect for musicians who want to write down their own songs or who want to learn new songs and don’t know how to play them.

The note analyzer works with pitch detection and frequency analysis (like FFT Fast Fourier Transformation for example) and is perfect for musicians (especially vocal and guitar or piano players). The note analyzer listens to your music, analyzes it’s pitch and converts your music back into an alternative sheet music. You can use it to detect the notes of your songs (note identification, the app helps you creating a transcription), validate the pitch of your voice, sing into the microphone and use it as a vocal trainer or to transcribe your songs while playing along with your guitar (or whichever instrument you are playing). And of course, you can also use the note recognition app as a simple audio / voice recorder.

This note detector won’t extract 100% of the played notes but depending on the quality of the signal the note detection algorithm will do a good job and will give you useful sheet music suggests. Because the detector can’t separate multiple instruments you will get the best results if just one instrument is playing simultaneously or if you record your voice without any background music. Also, you should place your phone in front of your instrument, your voice or your speakers to improve the detection quality.
