Logic Pro microphone input cuts out while recording (but works fine in QuickTime)

I’m experiencing an issue with my MacBook Pro 14" (macOS Sequoia 15.6) where the microphone input cuts out in Logic Pro during continuous recording.

When I record with the MacBook Pro built-in microphone or with an external USB microphone, Logic Pro captures my singing but suddenly drops to silence, even though I’m singing continuously.

This happens even with a clean track (no plugins, Input 1 selected, no Noise Gate, large buffer size).

However, if I record in QuickTime Player, the microphone input is clean and continuous, with no dropouts.

This suggests that Logic Pro is not getting the same raw audio stream that QuickTime does, and may instead be routed through macOS’s voice-processing path (noise suppression / gating).

Steps to reproduce:

1. Open Logic Pro.
2. Create a new project, add an audio track with Input 1 from “MacBook Pro Microphone.”
3. Record continuous singing.
4. Playback shows sudden cutouts (around 4–8s in my test).
5. Compare with a QuickTime recording (clean, no cutouts).

What I’ve tried:

• Changed I/O buffer size (64 → 1024).
• Disabled plugins and Noise Gate.
• Closed all background apps (Zoom, Chrome, Discord, etc.).
• Tried both built-in and external USB microphones.
• Tested QuickTime — which records without cutouts.

Question:

Why does Logic Pro not get the same raw audio feed as QuickTime, and is there a way to disable Apple’s voice-processing/noise suppression layer for Logic Pro?

This makes Logic unusable for singing/vocal work with the built-in mic and also with my external microphones (Rode NT1-A and Rode NT-USB)

, while QuickTime works fine.
