The group Agents Del Futuro let me into their studio to capture some live recordings with the Zoom H4n handheld recorder. These test recordings alternate between 2-channel recordings using the H4n's built-in stereo microphones, and 3/4-channel recordings that combine the built-in mics with external line and mic sources routed into the H4n. None of the recordings have been doctored in post-production, except to add fades and adjust volume levels. My full review of the Zoom H4n will post on CNET.com 04/13/09.
