I would like to display on a chart the audio-in (microphone) from my PC soundcard. It is possible?

Thank's.

No, there is no direct support from our side. However there is a free audio package which generates uncompressed WAV streams:

http://www.delphiarea.com/products/delphi-packages/waveaudio/

Using this package you can easily display the sound data by reading the RIFF chunk of the WAV file and displaying it in RChart.

Hope this helps,

Hans
