Frequently Asked Questions
Will the Nightcore version be louder than the original?
Speeding up audio can briefly push transients above 0 dBFS. We apply a soft-knee limiter on export to prevent clipping while preserving perceived loudness.
Is this tool really free?
Yes — every Rys Up Audio tool is 100% free, with no signup, watermark, or upload limits. The free tools are how we introduce producers to our paid plugins and vocal presets.
Do you upload my audio to a server?
Most tools process audio entirely in your browser via the Web Audio API — your file never leaves your device. AI-powered tools (stem splitting, vocal removal) run on cloud GPUs and the input is deleted immediately after the job finishes.
What audio formats are supported?
Every tool accepts MP3, WAV, FLAC, M4A, and OGG up to 50 MB per file. Exports default to high-quality 16-bit WAV.
Does this work on mobile?
Yes — every tool is responsive and works in iOS Safari and Android Chrome. Some tools (like the virtual piano) are optimized for multi-touch.
