i have to admit that i'm just a beginner with Symbian OS development (however quite experienced with MFC and QT APIs), just installed all tools and written my first console application. My goal is to write an application for guitar tuning, which should
1. capture the tone with the MIC (needn't to be realtime, also a short snapshot of 1 second is ok)
2. doing some analysis on this stream/file (FFT...)
3. showing the mistuning error graphically (with arrows or an analog pointer device)
Before diving deeper and deeper into all the APIs, can anybody confirm me that is possible? I'am sure, that steps 2 and 3 can be performed but how about step 1? I am grateful for all hints and also of course for sample code! Thanks in advance!
