      Hi everyone,

      this is my first post here.

      I’m going to start with a new theatre-oriented documentary for school (and perhaps for a competition).
      Up to now I’ve made video-oriented stuff, and a good stereo-audio was more than sufficient. But my last work was recently shown in a theatre as DCP and I heard the lack of a more complex audio track.
      So, for my next work I’ll try to build a 5.1 audio track.
      Anyway there are 2 conditions:
      1. I’m a one-man crew, so I’d need to use an effective form factor audio recorder mounted on my camera;
      2. The kind of sounds I need to capture are ambient sounds (then no interview set) like audio in nature documentaries.

      So, please, I need your advices.

      I tried to figure out what to buy:
      First of all I thought to avoid a camera-connected microphone, for the simple reason that camera’s pre-amps are not so good and add noise. So I thought to go for an external recorder, and specifically for a recorder with built-in mic (avoiding having cables that can produce noise if inadvertently touched buy the operator).

      REAL SURROUND RECORDER
      The first option seems to be Zoom H2n (https://www.bhphotovideo.com/c/product/811053-REG/Zoom_ZH2N_H2n_Handy_Recorder_Portable.html): this tiny recorder gives a true surround 4-channels audio thanks to 3 front capsules and 2 rear capsules. It seems great but I have 2 doubts here: 1. the little capsules are not “deep” like a shotgun, so I’m afraid they can capture only a near sound field (and perhaps also the noise of camera or operator’s steps); 2. having the recorder mounted on the camera, the 2 rear capsules will capture the noise from the operator actions!

      FAKE SURROUND FROM STEREO
      Since what I wrote above, I thought another solution could be buying a stereo recorder instead, to have at least 2 varied channels from which I could build a fake surround in post. Stereo recorders with integrated mics are:
      1. Sony PCM-D100 (https://www.bhphotovideo.com/c/product/1008089-REG/sony_pcm_d100_portable_stereo_field.html): the pros are S/N ratio up to 100dB and the variable angle of the mics’ capsules from 90° to 120°;
      2. Tascam DR-100mkIII (https://www.bhphotovideo.com/c/product/1263849-REG/tascam_dr_100mkiii_linear_pcm_recorder.html): the pro is S/N ratio of 109dB thanks to the AKM AK4558 converters, but mics’ capsules are fixed in parallel position;
      I’m wondering if these products can record a deeper sound-DoF than the Zoom H2n?
      If I’d go for one of this stereo recorders, I should process the 2 channels to obtain a fake 5.1 in post.

      MISSION IMPOSSIBLE: FROM SHOTGUN MONO TO FAKE SURROUND
      Many videographers use shotgun mics for their cameras, so I found 2 models with integrated recorders:
      1. Tascam DR-10SG (https://www.bhphotovideo.com/c/product/1257804-REG/tascam_dr_10sg_camera_mountable_audio_recorder.html);
      2. Shure VP83F LensHopper (https://www.bhphotovideo.com/c/product/966010-REG/shure_vp83f_condenser_shotgun_mic.html?sts=pi) that declares a S/N ratio of 78dB (a bit poor in comparison with the stereo recorders above). Here the doubts are: 1. a bit noisy mics; 2. do you think is it possible to build a fake 5.1 in post starting from the shotgun mono recording? I suppose not, but I prefer to wait your advices.

      Now, please, tell me which solution do you recommend for my purpose?

      Thanks for your help.

      What I use is one of these – http://www.ebay.com/itm/8GB-Digital-MP3-Player-Audio-Voice-Recorder-Rechargeable-Dictaphone-Telephone-/222317789532?var=&hash=item33c32c415c:m:mM1Pa8BZrL7W5Kg3ybsPFkA
      I can either plug a Mic into it or my 6 channel mixer and it has the plus of being a MP3 player when not using it to record something. If you want true surround sound, You will need an Audio Mixer and several Microphones. Then you will need to sync everything up. Unless your Video Editing Program has the ability to sync up Audio, then then best way is gather all the Microphones, have them within a Loud clap you make in front of the recording Camera. Then without turning off anything, place microphones where needed and start recording the scenes.

      It really depends of how you want to use it. If it is for gaming strictly then the one that Dave stated will do the job.

      I use an H2n mounted on my Canon G40. It works extremely well. I record stereo in M/S, but have used it in surround as well. No problems with operator noise. Now with the latest firmware update it can record in Ambisonic B-format which can be decoded into multiple surround formats including 5.1. The H2n also outputs a live stereo signal that can be plugged into your camera, if it accepts a line input, for recording at the same time and bypassing the cameras own mic. It records in WAV format rather than inferior mp3. Also a very effective deadcat is available for those windy locations.
