Audio to BGM Converter

The tool analyzes the input audio to extract tempo, mood, and spectral characteristics. It then generates an instrumental background track by mapping to a chosen style preset and aligning the output duration. This yields a cohesive bed that fits voiceover or dialogue without overpowering it. The core value is speed, consistency, and format flexibility for production pipelines.
Conceptually, beat tracking and tempo estimation guide time-stretching and alignment, while chroma-based key estimation informs palette choices for harmony. An instrument palette and arrangement rules produce the BGM, which is then mastered to a target loudness. Users can adjust tempo, key, and mood to match scenes or branding. The output formats (MP3 or WAV) and metadata support easy integration into editors and DAWs. Unique differentiators include automated tempo synchronization, modular style presets, and export with standard audio metadata. Use cases span video overlays, livestreams, podcasts, and game cutscenes. Core features include file upload, target duration, style presets, tempo and key controls, loudness normalization, and MP3/WAV exports.
