Does Screen Recording on Mac Record Audio?
QuickTime Player's screen recording feature includes a dropdown for selecting an audio source. The options are "None" or any connected microphone. The system's internal audio output (music, game sounds, browser audio, soundboard output) is not available as a recording source. Apple removed this capability from macOS years ago to prevent unauthorized audio capture.
The Screenshot toolbar triggered by Cmd+Shift+5 has the same limitation. Users can select a microphone for voiceover narration, but internal system audio is excluded. This means tutorial creators, educators, and streamers cannot capture application audio in their screen recordings without additional software.
A virtual audio driver solves this problem by creating a new audio device that captures system output and presents it as a microphone input. Screen recording software then selects this virtual device as its audio source, capturing every sound the Mac produces.
How Do You Screen Record on Mac with Internal Audio?
- Download and install the virtual audio driver one installer, no restart required
- Open the menu bar app and toggle the audio bridge on creates the virtual device automatically
- Open your screen recording app (QuickTime, OBS, ScreenFlow, or Camtasia) any recorder that accepts microphone input
- Select LitLink Audio Bridge as the microphone or audio input source appears in the audio device list
- Start the screen recording all system audio is now captured
QuickTime Player users click the dropdown arrow next to the Record button and select LitLink Audio Bridge from the microphone list. OBS users add an Audio Input Capture source and set the device to LitLink Audio Bridge. ScreenFlow and Camtasia both show the virtual device in their audio input settings during recording configuration.
The virtual driver runs at the kernel level with sub-millisecond latency. Audio quality matches the original source exactly because the driver passes raw audio buffers between applications without compression or resampling. Sample rates of 44.1 kHz and 48 kHz are both supported.
How Do You Screen Record on MacBook Air with Sound?
MacBook Air models have no special audio limitations that affect screen recording with internal audio. The built-in speakers and microphone work independently of the virtual audio driver. The driver creates a separate virtual device that coexists with the hardware audio without conflicts.
Users on older macOS versions (13 Ventura and below) should check driver compatibility before installing. The recommended virtual audio driver requires macOS 14 Sonoma or later. Users on older systems may need to use BlackHole as an alternative, which requires manual Audio MIDI Setup configuration for the multi-output device.
What Is the Best Screen Recorder for Mac with Internal Audio?
OBS Studio is the most flexible free option. The application supports multiple audio sources, scene switching, and direct streaming to Twitch and YouTube. OBS configuration for internal audio requires adding an Audio Input Capture source and selecting the virtual audio device. OBS records in MKV or MP4 format at resolutions up to 4K.
QuickTime Player is the fastest option for quick screen captures. The recording starts in two clicks and saves directly to the desktop. QuickTime lacks editing features, scene management, and streaming capability, but the simplicity is ideal for short tutorial clips and bug report recordings.
ScreenFlow and Camtasia both include timeline editors, transitions, callout annotations, and export presets for social media platforms. These paid tools are best suited for professional content production where editing happens inside the same application as the recording.
How Do You Record Screen with Both Internal Audio and Microphone?
The mic passthrough feature mixes your physical microphone signal with the system audio output before sending the combined stream to the virtual audio device. The screen recording application selects this single device and captures both your voice and all system sounds simultaneously. No additional audio routing or configuration is required.
- Open the virtual audio driver menu bar app click the icon in the macOS menu bar
- Toggle mic passthrough on enables microphone mixing
- Select your preferred microphone from the dropdown built-in mic, USB mic, or audio interface
- Start your screen recording with the virtual device as audio input both streams are captured
Without mic passthrough, users would need to record microphone audio as a separate track and sync it in post-production. The passthrough feature eliminates this extra step by delivering a single combined audio stream to the recorder. The microphone level and system audio level are mixed in real time with no perceptible delay.
This setup is essential for tutorial creators who demonstrate software while explaining steps, educators who screen record lectures with application demos, and streamers who play game audio alongside voice commentary. The combined audio stream works in QuickTime, OBS, ScreenFlow, Camtasia, and every other macOS screen recorder that accepts microphone input.
