How Increase Microphone Volume on Android


Are you in a situation where your microphone volume is too low? Does your friend on the other end keep asking you to speak up? You are desperately in need of a way to increase your microphone’s volume on Android, and it just so happens you’ll find a said solution here.

Since Android is void of any microphone settings, you’ll have to turn to software to make it work. You know, an app. After all, there’s an app for everything, right? What you need is an app that can amplify your voice.

Increase Microphone Volume with Microphone Amplifier

1. Download and install Microphone Amplifier (Android). Visit the Google Play Store and search for “Microphone Amplifier.” Select it from the search results and tap Install.

Note: It’s developed by Mobile Apps Studio.

2. Now launch the Microphone Amplifier app. It’s app icon is orange with the iconic Droid logo stamped in black.

3. Once the app is opened, start by tapping Enter Amplifier.

Audio Gain slider

4. The first slider, the Audio Gain slider, is your first (and only) target. This will increase the volume of your voice.

Note: Be careful with how much gain you add. The more gain added, the worse the sound quality gets. Somewhere between 10 to 20 is good, but play around with it to see what works for you.

5. In the bottom left corner you’ll see the power icon. Tap on it. In doing so, Microphone Amplifier will apply the settings you’ve made.

Note: To test your new settings, record your voice with your settings enabled. You want your voice to be clear. If there’s too much static, try reducing the gain in small increments. And don’t forget to practice good mic placement. Keep the mic about 2 to 3 inches away from your mouth.

6. To disable the filter Microphone Amplifier added, tap the power icon again.

7. To reset your settings, tap the Reset icon at the bottom—the arrow chasing its tail. When prompted to confirm, tap Yes.

Still Having Issues?

If you implemented some of the solutions above and are still running into low microphone volume, the issue may rest with the microphone itself. There’s a few troubleshooting steps you can take to ensure the microphone isn’t the problem.

Double-check Sound Settings

You may have placed your device on silent or Do-Not-Disturb. Use the volume buttons on the side of your Android device to remove it from silent mode.

Additionally, external microphones come with a Mute button. Make sure it hasn’t been enabled. Also, some microphones come with a volume wheel that controls the volume of your voice on the other end of the call.

Clean Your Microphone

Dirt, lint, dust—all manner of blockage—is capable of preventing your voice from being picked up fully by your microphone. Imagine trying to talk to someone behind a wall, and you’ll understand how a wall of debris can block sound from reaching your microphone.

With a thin object, something like a sewing needle, safety pin or better yet, a wooden toothpick can be inserted into the microphone. Gently insert the object and, in a circular motion, break free any lint or dirt that may be trapped inside.

Use Another Microphone

You might be dealing with a microphone that has shorted. Are they old? Perhaps the wires are disconnected on the inside. Did you get them wet at some point? Either way, any damage your microphone has experienced may have killed them for good.

Try using them on a different device or switch them out with another microphone and see if the second pair works. If they do, your first pair are likely damaged.

Turn Off Noice Reduction

Another feature that you can do to increase the volume of your microphone is to use the noise reduction feature. The noise reduction feature is there to remove any background noise that can interfere with the performance of your microphone.

To turn off noise reduction:

  1. Open the Settings menu.
  2. Tap Call Settings.
  3. Look for the Noise Reduction option. If you cannot find it, you can use the search function to search Noise Reduction. If you can’t find it, it’s probably because your Android doesn’t have this feature.
  4. Tap the toggle switch to disable Noise Reduction.
  5. Restart your phone and see if the problem is fixed.

Check For An Update

There could be a bug in your os that’s preventing your microphone from functioning properly. The best thing to do in this case is to check for an update. Updates are there to get rid of bugs and this can make the volume of your microphone louder.

Updating your Android:

  1. Make sure your device is connected to Wi-Fi.
  2. Open Settings.
  3. Select About Phone.
  4. Tap Check for Updates. If an update is available, an Update button will appear. Tap it.
  5. Install. Depending on the OS, you’ll see Install Now, Reboot and install, or Install System Software. Tap it.

Disable Third-party App

Sometimes a third-party app could be the culprit of your microphone being so quiet. If you think this is the case, then you can, you can deny that app access to your microphone. Use the following steps to deny microphone permissions for any apps that don’t need to use your microphone:

  1. Open the Settings app.
  2. Tap Apps
  3. Select the menu icon
  4. Select App Permissions or Permissions Manager.
  5. Select Microphone or Microphone Permissions.
  6. Select the app that you think is causing a problem with your microphone.
  7. Tap Deny to deny it microphone access.

Bottom Line

From additional software to native options, there’s plenty of ways to increase your microphone’s volume on Android devices—Microphone Amplifier isn’t the only app available on the Google Play Store. It can be incredibly helpful if you have a microphone that, even at full volume, still isn’t loud enough. And on top of that, the options above may just save you a trip to the nearest electronics store.
