How to set the gain with Mikme OS 0.70 and higher.
What is the gain of a microphone?
The gain of a microphone sets the sensitivity of the audio input. When setting the gain you increase or reduce the strength of a recorded audio signal in order to optimise it for further signal processing.
Weak Audio Signal: Increase gain
If you have a very silent or weak input signal you'll want to set a higher gain to get a better signal-to-noise ratio for your recording. Otherwise the low signal can lead to an unwanted noise in your recording.
Strong Audio Signal: Decrease gain
If you have a very loud input signal you need to lower the gain. Otherwise the signal fed into the Analog Digital Converter (ADC) will be too loud. This leads to an overdrive and distorted sound.
Signs for an incorrect gain setting of your Mikme
Indications for a too high gain (leading to distortion):
- Microphone: The microphone's top LED flashes irregularly (from color to no color)
- App: An exclamation mark next to the gain menu icon and red parts in your audio wave form.
Indications for a too low gain (leading to noise):
- Microphone: You can’t hear anything or need to increase the volume when monitoring the audio signal with your headphones.
- App: You don’t see any or a very low audio wave form.
How do I set the gain of my Mikme Microphone?
A – Set the gain on the Mikme Microphone
In the following steps you learn how to access the Gain menu on your Mikme Microphone.
1. Access gain mode
Press and hold the top capture button for at least 1 second till the top LED shines pink.
2. Check or adjust the gain
Set and adjust the gain by pushing the +/- buttons on the rear side of the Mikme Microphone while you’re checking the sound (speech, music). The gain is set properly when there is no irregular flashing of the top LED anymore while you’re speaking, singing etc. An irregular flashing indicates there is still a signal overload (= distorted sound), which requires to lower the gain with the - button a little bit more.
You can set the gain from 0-30 dB.
When the top LED flashes irregularly you need to reduce the current gain setting. If you already set the lowest possible gain, you can increase the distance to the sound source to reduce the signal level of the microphone's input.
3. Save the gain
Once you’ve finished, push the top button again. It turns back shining either white (standalone use) or blue (app use). The gain is now saved for future recordings, even if you switch off the Mikme Microphone.
We recommend performing a sound check and setting the gain before a recording. In this short video we show you again the 3 steps as explained above:
If you need to change the gain during an ongoing recording, follow the same steps and access the gain menu. In this video we'll show you how to adjust the gain during a recording:
B – Set the gain using the Mikme App
In the following steps you learn how to access the microphone’s Gain menu remotely via the Mikme App:
1. Connect your Mikme Microphone in the App
2. Open the App settings & click on your selected Mikme Microphone
3. Adjust the gain using the INPUT GAIN fader
You can set the gain from 0-30 dB in 1-3 dB steps using the fader in the setting screen.
As long as the microphone's top LED is flashing, the gain is too high and the audio signal peaks and is too loud. To set a lower gain, move the fader to the left until the top LED on the microphone stops flashing while recording speech, music etc
4. Exit the settings
Once you're done, exit the settings menu. The last INPUT GAIN setting will be stored automatically on the microphone and in the App.
