How to Record Audio with Video in AZ Screen Recorder: A Guide to Internal and Mic Audio

Have you ever finished recording a video of your phone screen, only to find it was utterly silent upon playback? This is one of the most common issues users face with screen recording apps. For producing tutorials, gameplay footage, or capturing an important video call, recording audio with video in AZ Screen Recorder is a vital capability.

Users often don’t know whether to enable microphone audio for their own commentary or internal audio to capture system sounds and games.

In this article, as your expert guide, we will not only explain the difference between internal and Microphone audio in AZ Screen Recorder but also provide you with a step-by-step process for enabling the Microphone in AZ Screen Recorder or recording system audio, ensuring your videos are never silent again.

Why Is Audio Recording Important in AZ Screen Recorder?

Audio makes up more than half of the user experience. A tutorial video without clear voice commentary or gameplay footage without exciting game sounds has little value for the audience. To meet this need, AZ Screen Recorder offers two primary audio sources:

1. Microphone Audio (Mic)

• Definition: This option records ambient sounds and your voice (via the device’s built-in Microphone or your headset microphone).
• Use Case: Ideal for tutorials, commentary-driven videos, or any situation where you need your own voice overlaid on the video.

2. Internal Audio

• Definition: This option records only the sound generated by the operating system (such as game audio, music, or video call sounds), filtering out ambient noise.
• Use Case: Suitable for gamers and users who want to record audio from a movie or app without interference from external environments.

Internal vs. Microphone Audio in AZ Screen Recorder

Audio Type	Function Description	Primary Use Case	Key Limitations
Microphone (Mic)	Records ambient noise and speaker’s voice.	App tutorials, product explanations, gameplay (with commentary).	Susceptible to environmental noise, potential for hissing sounds.
Internal Audio	Records sound inside the system (games, apps).	Game recording (without external noise), video calls, music playback.	Android 10 and above only.

 

Prerequisites for Recording Audio in AZ Screen Recorder

Before starting the AZ Screen Recorder audio recording tutorial, ensure your device meets the necessary conditions:
Android Version (Mic): Your device must have Android 5.0 (Lollipop) or higher for AZ Screen Recorder to access the Microphone.

Android Version (Internal Audio): Due to operating system restrictions, internal audio recording in AZ Screen Recorder is natively enabled only on Android 10 and above.

App Permissions: Ensure that you have granted AZ Screen Recorder the necessary permissions for Microphone and Storage in your phone’s settings.

Storage Space: Simultaneous audio and video recording requires more storage space. Ensure you have enough free space on your phone’s memory.

How to Enable Microphone Audio in AZ Screen Recorder (Mic)

This is the easiest and most accessible way to enable the Microphone in AZ Screen Recorder and works on all Android versions:

• Access Settings: Open the AZ Screen Recorder app and tap the gear icon (Settings) on the Floating Widget toolbar.
• Audio Settings Section: Scroll down to the Audio Source option and tap on it.
• Select Microphone: Choose Microphone from the available options.
• Start Recording: Return to the main screen. Now, when you press the record button (represented by the red camera icon), ambient sound will be recorded simultaneously with the video.
• 📌 Pro Tip: If your video is purely educational and requires speaker audio, be sure to use quality headphones with an external microphone to reduce environmental noise (hissing) and get clearer audio.

 

How to Record Internal Audio in AZ Screen Recorder (Android 10+)

As mentioned, recording internal audio in AZ Screen Recorder is a unique feature for Android 10 and above that helps gamers record game audio at high quality without needing an external microphone:

1. Access Settings: Return to the Settings menu (represented by a gear icon) in AZ Screen Recorder.
2. Select Audio Source: Tap on the Audio Source option.
3. Choose Internal Audio: Select the Internal Audio or System Sounds option this time.
4. Confirm Permissions: The app may request specific permissions the first time; confirm these permissions.
5. Start Recording: You can now start recording. Only the sound from open applications (like games or calls) will be captured.
6. ⚠️ Crucial Warning: If you select the Internal Audio option on a device running Android 9 or lower, the video will likely remain completely silent. The fix for this AZ Screen Recorder audio issue is to revert to the Microphone option.

 

Recording Both Internal and Microphone Audio (Mix Audio)

Some newer versions of AZ Screen Recorder offer this advanced capability, enabling the simultaneous recording of both game audio and speaker audio (microphone). This mode is ideal for commentary gameplay videos:

1. In the Audio Source menu, look for an option like Internal Audio and Microphone or Mix Audio.
2. By selecting this option, AZ Screen Recorder will record both audio sources into a single file.

⚠️ Audio Conflict: Note that this mode puts more strain on the phone and may result in lag and audio conflicts on weaker devices. If problems arise, disable one of the sources.

Suggested Settings for Better Audio Quality

To ensure your audio is recorded clearly and professionally, simply optimise the audio settings according to your recording goal:

Recording Goal	Audio Source	Special Quality Suggestions
App Tutorial	Microphone	Use a good headphone microphone and record in a perfectly quiet environment.
Gameplay Recording	Internal + Microphone	Use headphones to listen to game audio while speaking, and ensure Noise Reduction options are enabled (if available).
Video Call	Internal	Conduct a brief test call before recording to ensure both parties’ voices are captured.
Educational Video	Microphone	Maintain a clear tone and appropriate speaking pace. The microphone should be at an ideal distance to avoid weak audio or capturing breath sounds.

 

Troubleshooting Common Audio Recording Issues

Error or Problem	Primary Cause	Definite Solution
Video is silent	The Record Audio option in settings is off.	Go to the AZ Screen Recorder settings menu and enable the Record Audio option.
Hissing or excessive noise	Environmental noise, poor internal microphone quality.	Use a headset (headphones with a mic) and record in a
		completely silent environment.
Internal audio is not recorded	Android version is below 10.	Your phone doesn’t natively support this feature; select Mic only.
Audio conflict	Simultaneous activation of the microphone and internal audio conflicting with device limitations.	Disable one of the audio sources or restart your phone before recording.

Pro Tips for High-Quality Audio Recording

1. Test Before Recording: Always record a short 5-second video before the main content and play it back to ensure the audio (both Mic and internal) is working correctly.
2. Audio Quality: If AZ Screen Recorder allows you to adjust the audio Bitrate, set it to 128 kbps or higher; this is the standard for high-quality audio.
3. Leverage Editing: If there is minimal noise in the recorded audio, you can use video editing applications (such as CapCut or InShot) or desktop software to remove the noise afterwards.
4. Battery Charge: Simultaneous audio and video recording drains the battery. Ensure your battery level is sufficient for the entire recording duration.

 

Frequently Asked Questions (FAQ)

1. Why won’t internal audio record in AZ Screen Recorder?
The main reason is either your device is running Android 9 or lower (which doesn’t natively support this feature) or you haven’t granted the necessary permissions to the app.

2. Can I record both my voice and the game audio simultaneously?
Yes, on devices with Android 10 and above, you can select the Internal Audio and Microphone (or Mix Audio) option to record both sounds simultaneously.

3. How do I remove microphone noise?
To resolve AZ Screen Recorder audio issues and eliminate noise, the best approach is to use high-quality headset microphones and record in a quiet environment.
4. What audio is best for video tutorials?
Definitely the Microphone (Mic), as the speaker’s voice is the most crucial part of a tutorial video. Internal audio is only needed if you want to include the app’s sound simultaneously with your explanation.

5. Does recording audio increase the video file size?
Yes, adding a quality audio track (especially if the audio Bitrate is high) slightly increases the final file size. Still, this increase is negligible compared to the size increase caused by the video Bitrate.
