About Audio Merger
Last updated: May 2026
OptiPix Audio Merger kombinerer 2-20 lydfiler til et enkelt spor direkte i din browser. Upload flere lydfiler, omarranger dem med træk-og-slip-kontroller, og indstil varigheden af mellemrum mellem spor. Eksporter i MP3, WAV, OGG, FLAC eller AAC med justerbar bitrate. Mergeren håndterer forskellige inputformater automatisk - bland MP3, WAV og OGG-filer i samme sammensmeltning. Bruger FFmpeg.wasm concat demuxer for output af høj kvalitet. Al behandling sker lokalt.
How It Works
Værktøjet skriver alle inputfiler til FFmpeg.wasm's virtuelle filsystem, opretter en sammensmeltningsliste og kører derefter FFmpeg concat demuxer for at samle dem i rækkefølge med valgfrie mellemrum mellem sporene.
