¿Cómo grabar audio por separado en OBS?

High-quality audio is just as important as video—sometimes even more so. Whether you’re recording gameplay, online courses, tutorials, podcasts, or business presentations, having separate audio tracks gives you far greater flexibility in post-production. You can adjust microphone volume independently, remove background noise without affecting system sound, or completely mute one source if needed.

OBS Studio is a powerful, free tool that supports multi-track audio recording, making it possible to record microphone audio, desktop sound, and application audio separately. However, many users find OBS audio settings confusing at first, especially when they just want clean, separate audio without complex routing.

In this guide, you’ll learn how to record audio separately in OBS step by step, understand common use cases, and discover a simpler alternative for those who want separate audio tracks without complicated configuration.

1. How to Record Audio Separately in OBS?

OBS does not create separate audio files by default, but it allows you to record multiple audio tracks within a single video file. These tracks can later be edited independently in professional video editors such as Adobe Premiere Pro, DaVinci Resolve, or Final Cut Pro.

Method 1: Record Microphone and Desktop Audio on Separate Tracks (Recommended)

This is the most common and practical way to record audio separately in OBS.

Step 1: Enable Advanced Output Mode

Abierto Estudio OBS → Ir a Settings → Output → Cambiar Modo de salida from Simple a Avanzado → Haga clic en el Grabación pestaña.

This unlocks multi-track recording options.

Step 2: Enable Multiple Audio Tracks

Under the Audio Track section:

• Controlar Track 1
• Controlar Track 2
• Optionally check Track 3 or Track 4 if needed

Each track will hold a different audio source.

Step 3: Assign Audio Sources to Tracks

• In the OBS main window, find the Audio Mixer
• Haga clic en el ⚙️ gear icon next to any audio source
• Seleccionar Advanced Audio Properties

Now assign tracks:

• Desktop Audio (game/system sound) → Track 1
• Microphone / Mic-Aux → Track 2
• Optional (Discord, music, browser audio) → Track 3

Uncheck tracks you don’t want each source to appear on.

Step 4: Choose the Best Recording Format

Ir a Ajustes → Salida → Grabación and set:

• Formato de grabación: MKV

MKV is recommended because it prevents file corruption if OBS crashes. After recording, you can convert it to MP4 using:
File → Remux Recordings

Method 2: Record Application Audio Separately (Windows 11)

If you want to isolate audio from a specific app (for example, a game or browser), OBS provides Captura de audio de la aplicación .

Pasos:

• Hacer clic + in the Sources panel → select Captura de audio de la aplicación
• Choose the target application
• Assign it to a separate audio track via Advanced Audio Properties

This method is ideal for:

• Recording game audio without system sounds
• Separating browser audio from microphone narration

Method 3: Record Microphone Audio Only

For voiceovers, narration, or podcast recording:

• Ir a Configuración → Audio → Desactivar Audio de escritorio
• Colocar Micrófono/Audio Auxiliar to your microphone and start recording

This produces a clean voice track without background system sounds.

Method 4: Record Audio as Separate Files (Advanced Users)

OBS is not designed to export individual WAV or MP3 files per track. To do this, you’ll need:

• Virtual audio cables (such as VB-Audio Cable)
• An external audio recorder (Audacity, Reaper)

This approach is powerful but significantly more complex, making it less suitable for beginners.
