There are two major options for improving GoPro sound: either you can use external microphones with your device or prefer to connect an independent recording system.
1. Using External Microphone
Before choosing the external microphones, there are a few things need to consider.
1. GoPro Microphone Adapter:
GoPro Hero2 used to have dedicated audio input port of 3.5 mm but after that all GoPro cameras were developed without dedicated audio port. So now you have to use an additional Mini USB port for making connection with external mics. You can buy Pro 3.5mm Mic Adapter to insert external mic into your Hero5 session and Hero5 Black device. It enables line input and stereo mic for external audio sources such as mixer or audio recorder. For HERO4 Black, HERO4 Silver, HERO3+ and HERO3, you need to buy the 3.5mm Mic Adapter .
2. Microphone Friendly Housing:
The GoPro protective waterproof case never allows direct access to Mini USB port, so you may have to use your camera naked to access these ports. If you use alternative housing to access ports through cutouts then your device will not stay safe from water anymore. The best option is to use microphone friendly hard plastic frame that can provide better protection while allowing direct access to ports. This frame picks all sounds well from external mics.
3. Choose Right External Microphone:
There are so many external microphone products available in market that can assist users in picking up ambient sounds, music as well as speaking voice. Some of the best options that are compatible with all GoPro models are:
Sony ECMCS3 clip style Omni-directional stereo mics.
In case if you cannot connect your microphone due to absence of sound buffle then it is good to buy a foam windscreen as it can easily reduce external noise during windy environment. If you install this foam windscreen, then it will become much easier to record sound even during biking and surfing. It can instantly boost the audio quality.
2. Using Independent Recording System:
It is really a great idea to use totally independent recording system with GoPro action camera if you are not in favour of connecting external microphones. These independent systems assist us clear voice recording as there is no disturbance caused by external protective case. You can find so many stand alone devices in market but Zoom H1 and Zoom H2 is recommended as best tools by professionals for high quality audio recording. It can perfectly balance your budget and quality needs. Note that here you need to make additional efforts in post processing as it is desired to merge recorded audio signals with proper synchronization to video. The price range of such independent recording systems uses to be much higher but still we have picked an affordable option for you that can provide rich quality:
