External microphones for DSLR or Mirrorless Camera
Microphone is a transducer that converts the sound into electric signal via preamplifier.
Electric signal is then converted into digital format and stored in various formats like .mp3, .wav etc
There are many types of microphones out there in the market.
External microphones are useful when recording videos in noisy places.
Also when the subject is located too far from camera, we can use wireless microphone or even
go for standalone voice recorders as well.

Digital voice recorders
When the subject is too far from Camera, you need to record the audio and video separately.
You can record the voice in seperate recording device by using Digital voice recorders.
Wireless microphones can be used but they are very expensive.
You can buy Zoom H1 digital recorder on Amazon
You also need to buy the lapel microphone. Also note that sample rates of both audio and video should
be in synch (normally 48 khz). I do not prefer recorders because you need to spend lot of time
synching video with audio while editing the video especially if you have taken multiple shots.
