I'm looking into a handheld for the sole purpose of recording those quick one-off ambiences: a subway station late at night, wind whistling in a stairwell of somewhere you're visiting when you don't have your full kit - you know the drill.
Out of the obvious H4N, PCM-D50, PCM-M10 etc. which onboard mics are the best at recording (sometimes quiet) ambiences? Any less popular recorders I should look at?
Thanks in advanced!
