There are many ways to use and control audio sources. The camera has advanced internal audio and many options for external audio sources. With so many input options the Mevo app provides you the ability to control each audio source individually as well as as a whole through the Audio Mixer function.
The Mevo app has a simple built-in Audio Mixer that allows you to control audio levels from various sources in addition to the overall audio output to your audience. To adjust your audio source and levels, tap the More Options (•••) icon in the bottom right corner.
Tap the microphone icon on the left side of the panel to enter the audio mixer.
Output
The Output (1) slider controls the overall Output of the mix to your audience. Anything located in the (2) area of this graphic is controlled by the output. Any adjustments made in (1) will effect (2) as a whole.
- The bottom of this panel will show a slider, mute button, and levels monitor for your audio Output, which is the audio your audience will hear. By default, this includes a mix of the camera's built-in microphone and your primary mobile device's microphone or a plugged-in audio source.
- Below the Output are sliders, Mute options, and Level Monitors for both the built-in microphone ("Mevo") and your mobile device's microphone or plugged-in audio source ("iPhone Microphone" - this may be labeled as "iPad microphone" or "Phone microphone" depending on the device you are using). Both of these are sending audio to the program output by default.
For each source, you can drag the slider to adjust the audio levels; dragging it left will lower the audio levels while dragging it right will make that source louder.
- Add external audio sources using the free Mevo Mic App.
Learn more about the Mic App here. - Edit Inputs - This will open a new window that displays all sources it detects and allows you to connect/disconnect to the audio sources. Type of sources that will be displayed USB Inputs, phone/tablet microphone and Mic App sources.
You can also mute that source entirely by tapping the microphone icon to the right of it; the corresponding levels monitor will indicate there is no audio being sent out.
A general best practice is for your audio levels to peak about halfway to two-thirds of the way up the levels bar. This ensures a clear, audible sound that is not too loud.
Audio that is over modulating is generally indicated by the top notches flashing red. This means you should lower your audio levels by dragging the audio slider to the left.
Monitoring
You can MONITOR what the output by toggling the speaker icon in the top right corner. Headphones are recommended when monitoring, to avoid feedback.
Unique Audio Settings
The Mevo 1st Generation/Plus share a few unique settings as does the Mevo Start with the advanced audio processing. You can click your model of camera below for settings specific to you.
Mevo Start Internal Microphones
The Start has a few advanced audio processing options to choose from. To view these options in the Audio Mixer just press the arrow next to your "Mevo "and you will see additional options like below.
Audio Processing
- General- This is the best option if you have a mix of both music and speech. It has minimal noise reduction and reverberation removal.
- Music- This is meant to capture a wide frequency range perfect for recording music. Noise reduction is off to avoid distortion.
- Speech- This uses all 3 internal microphones to estimate where the sound is coming from and then focuses on the detected audio and gives a high signal to noise ratio. This is called beam-forming. It reduces unwanted sound originating from behind the camera. This option has a high level of noise reduction and reverberation removal.
Auto Gain Control (AGC)
Automatic gain control will adjust the gain to give an consistent output to your viewers when the detected sound level varies. This setting will affect the audio processing options differently.
- Music- If AGC is enabled when using the music processing option the AGC will adjust slower than the other processing options. This is done to avoid an unbalanced audio affect.
- Speech- If AGC is enabled when using the speech processing option the AGC will adapt more aggressively than the other processing options to ensure the speech is delivered at the highest quality.
3.5 mm Line Input (TS/TRS)
The Mevo Start Audio mixer will automatically detect when a 3.5mm plug is inserted. This will disable the internal microphones. Other audio input sources may still be used.
Line In Level (Stereo)
- This is the input setting for LINE LEVEL signal. Examples include output from Audio Mixers, Music Players, Laptops, and Phones/Tablets.
Mic Level (Mono)
- This is the input setting for MIC LEVEL signal. Examples include output from Instruments or Microphones using a 3.5mm TS (Mono) connection.

-> Navigate to the Audio & Video menu.
Mevo 1st Gen / Plus Internal Microphones
If you are using the built-in microphone, be sure to place the camera close to your subjects, ideally about five feet away. The camera and its built-in mic work best when it is close to the action.
The camera's microphone is directional to space directly in front of it, but may still pick up general room noise. The closer the mic is to your subjects, the more it will filter out noise or chatter behind or to the side of it. The microphone will also follow the direction of your live edits; if you crop to a shot on the left side of the field of view, the microphone will adjust its directional focus accordingly.
The built-in microphone has configurable modes for enhanced performance depending on your environment. In the live edit view, tap More Options (•••) in the lower right corner -> Tap General Settings 
-> Navigate to the Audio & Video menu.
You will notice two modes:
- Music: Keeps the full frequency just like the default setting, but this setting adds some filtering and dynamic range compressions to prevent peaking from louder signals.
- Speech: Adds a low pass filter to increase clarity.
If you enable Speech mode, you will see an additional option for Noise Cancelation. Enabling this will help in environments when background noise (e.g street traffic, HVAC) can make it harder to hear the person speaking.
