MubLoop

Create seamless crossfade loops and clean audio clips from audio files, designed for game developers and audio producers.

Load an audio file, set a region, adjust settings and export a perfectly looping or trimmed WAV file in seconds.

Features

• Two modes: Loop and Clip.
• Supported import file types: WAV, OGG, MP3, AIFF.
• Export as WAV.
• Visual waveform with loop region selection.
• Source waveform zoom (scroll wheel), pan (middle mouse drag), and reset (double-click).
• Loop Mode: Adjustable crossfade length and position.
• Loop Mode: Equal power and smoothstep crossfade options.
• Loop Mode: Snap to zero crossing option.
• Loop Mode: Embed loop metadata for game engines (only tested in Godot).
  
• Clip Mode: Fade in and fade out.
• Output normalization.
