The Scarlett 2i2 interface can record at 24-bit resolution and has a maximum sample rate of 96kHz. This is ideal for podcasting with a remote guest. This is important if you’re only using one of the inputs and want to hear the input sound in both ears rather than having it play just left and right. The direct monitoring feature is so useful plus it can be turned off or set to monitor in mono or stereo mode. The superb Scarlett 2i2 interface has excellent preamps including a emulation of Focusrite's Air.
