In Part 2 of Canon 5D Mark II Audio Exposed, I compare the Microtrack II, Zoom H4n, BeachTek DXA-5D, and the juicedLink CX 231 when recording a camera-mounted long shotgun mic at five feet.
The only processing of the comparison audio was changing gain to match levels. You can download the uncompressed comparison audio here: p3pictures.com/audio_5d2/AudioExposed_Part2_OnCamera.zip
