Hi I still don't know JMF. I'd like to capture audio and to record it directly into memory. For the moment. I have taken sources and I have done a little program that record audio input in a MP3 file. It uses Processor, DataSource, MediaLocator. I'd like to know if there's a mean to create a DataSource or MediaLocator with a customized OutpuStream(the mine). It would allow me to do what I want with the output, so putting in memory. But there is perhaps an existing method that put audio input in memory or in buffer ? Can someone give me some URL, or JMF or java classes names, or methods to do this ? Xavier    More>>
