Freeze if wished. Mangoes can be frozen. The skin will turn black but the flesh will stay in good condition (it will be just a little softer than prior to freezing). You can freeze either the entire mango or you can freeze chopped up pieces.
James, you need to do a little research on ASIO Direct Monitoring. It's a standard tha allows an ASIO host to enable hardware monitoring in an interface that supports it. This bypasses The A/D/A converters and is true, zero-latency direct monitoring.
ASIO4ALL is a hardware independent low latency ASIO driver for WDM audio devices. It uses WDM Kernel-Streaming and sometimes even more sophisticated methods to achieve its objectives. The most used version is 2.10, with over 98% of all installations currently using this version.
