New app idea


- if preset fails, load default soundfont. Sound module. K it is the instruments error. 030215
- try service instead of worker. 090215
- volca sample download folder. So is the midi out player. 030215
- NYC trains data 010315

A graph library. Use a chart engine. Pass by bitmap? 




- an app to listen to count 1 in salsa music. 
- an app to determine keys in a music. I am interested to draw a waveform. To go to a point. And determine its keys. 
- a fft and cepstrum app. 
- a fft that gives fundamental freq using harmonic theory beside peak frequency.
- app that listen and tell you what things are running like ironing.
- an app module for graph. Pan. Zoom. Graph Module. Interesting! Return a canvas. 
- an app that display freq spectrum to piano scale. This look interesting! 270115
- an app that listen to baby sleep and send note when she wakes. 
- an app that listen to mosquito and alert user. 
- a graph app that provides drawing to my app such as waveform
- a toolbox of signal analysis tool
