ASIO Audio Tools adds a simple recording and WAV editing workflow directly to the Unity Editor on Windows.

Record a selected input channel from an installed 64-bit ASIO driver and save the result directly as a WAV AudioClip inside your Unity project. After recording, the clip can be opened immediately in the included Mini WAV Editor.

Features

• Select an installed 64-bit ASIO driver
• Select the physical input channel
• Record at 44.1, 48, 88.2, or 96 kHz
• Save as 16-bit or 24-bit mono PCM WAV
• Live input level meter and recording timer
• Stop and save with the button or Escape key
• Open recordings directly in the Mini WAV Editor
• Select waveform regions by dragging
• Double-click the waveform to select or clear the complete clip
• Crop to the selected region
• Delete selected regions
• Apply fade in and fade out
• Normalize the complete clip or a selection
• Undo and redo edits
• Preview through the Windows default playback device
• Open WAV AudioClips by double-clicking them in the Project window
• Save over the source WAV or create a new file

Requirements

• Unity 6.3 or newer
• Windows 10 or Windows 11
• A compatible installed 64-bit ASIO driver for recording

The Mini WAV Editor can also be used without ASIO hardware. Only the recording tool requires an ASIO driver.

This package is Editor-only and does not add runtime components to player builds.
