Subject: Re: Ultrasonic natural sound recordings From: Diego Martinez <diegomarti@xxxxxxxx> Date: Wed, 18 Apr 2012 13:33:39 -0300 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--f46d04426f1488d08804bdf6a034 Content-Type: text/plain; charset=UTF-8 Hello Nicol, you should care about wind and get some windshield, something from Rykote or Cinella or Sennheiser, but it has to fit the microphone you choose. Windshields usually come with suspension grips that reduce significantly handling and cable transmition noises, and also ground vibration. You can get some separate inexpensive suspension like the Sabrasom products. Coming to Zoom products you better get the "new" H4N, plain H4 is discontinued and its replacement is much better. The microphone you point seems to have very high noise level, maybe because its electret construction, but it could be OK for the application intended. zoom preamplifiers are not world class but you can try to get some frequency response chart and see if it is good for your work. Eventually you can get a separate preamplifier from Sound Devices for example. In any case check for responses above human frequency threshold, including windshield attenuation. Saludos!
