✨ Key Features

• 🔄 Seamless Crossfading: Automatically blends the end of your loop with audio previous to your starting point (Pre-roll Crossfade). This guarantees an invisible loop junction without killing the initial transient (punch) of your track.
• 🎯 Phase-Accurate Zero-Crossing: Automatically aligns your selection markers to the nearest zero-crossing points to eliminate annoying digital pops and clicks.
• 🏷️ Embedded SMPL Metadata: Exported WAV files include the standard smpl RIFF chunk. Unity and other game engines will automatically recognize the loop points upon import.
• 🎧 Real-time Processed Preview: "What you hear is what you get." The preview generates an in-memory processed version of the loop including crossfades and normalization.
• ⚡ Mono Summing: Quickly collapse stereo tracks into mono for optimized mobile, VR, or spatial audio workflows.
• 🌐 Localized UI: Support for both English and Spanish.
• 🛠️ Modern UX: Built with Unity's UI Toolkit, featuring a high-performance waveform view with zoom, pan, and interactive markers.
