How Do I Control Audio?

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.


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 Mevo 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 Mevo 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.

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.


Below this is the ability to Edit Inputs. Tapping this brings you to a screen allowing you to connect and disconnect external audio sources with the Mevo.

External sources include your mobile device, audio devices plugged into your mobile devices, and USB devices from the Mevo Boost or an OTG cable. By default, any detected sources are connected. Tap Connected to disconnect the audio source from Mevo so that it doesn't appear in the Audio Mixer; you can return here and tap Tap to Connect to reconnect the source. Please note that you cannot disconnect the built-in Mevo microphone.

Tap Done to exit the screen.


By default, the live audio preview (which allows you to hear your source audio through the mobile device's speakers) is muted. You can unmute it by tapping the speaker icon in the upper right corner. However, you may want to keep this muted during your stream; this will help avoid an echo in your stream and recording.

In this instance, we recommend pushing a test stream to your destination (e.g. stream to Facebook but select Only Me as the audience) and checking your audio quality there prior to your event.


To collapse the entire menu and return to the Live Production screen, tap the down arrow in the upper right corner.


A Beginner's Guide on Monitoring Audio Levels

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.


Mevo Start Audio Processing Options

 The Mevo Start has a few advanced audio processing options to choose from. To view these options in the Mevo 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 Mevo Start. 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.
