No. Using DirectSound/DirectShow you will get approximately 40ms latency in playback. DirectKS mode is hard. You have to handle everything yourself. For example the Creative Audigy runs at 48KHz in DirectKS mode which means you have to do resampling if you want to mix in CD Audio which is sampled at 44.1KHz. ----- Original Message ----- From: Nugen To: wdmaudiodev@xxxxxxxxxxxxx Sent: Thursday, February 02, 2006 5:17 PM Subject: [wdmaudiodev] Re: USBAudio and AVStream the fact is that i need a less than 10 ms latency... Is it possible with Directshow? thanks
