71981 audio viewer

Dear all, I would like to have a simple audio viewer which shows the waveform when the sound is incoming from handsfree, just like CRO. ( NO recording function is needed, just displaying ) Details / Requirements: 1. This application will be run on Nokia cell phone. 2. C++ is prefered, J2ME can be used also (If you are going to use J2ME, please make sure that the application can work on at least one of the Nokia phones (Please specify). As I know, Nokia 3650 does not fully support MMAPI, especially the audio API.) 3. Additional function a) show the frequency of the incoming sound. b) adjust the displaying range, say 1 to 10Hz (optional) 4. Testing method I will input a sound with different frequency around 1-10Hz. Here is a reference 1. Audio input stream example ( C++ with open code ) [login to view URL]
