Frequently Asked Questions
Does pitch-lock affect quality?
Yes — separating pitch from time uses an FFT-based phase vocoder, which introduces a small amount of "smearing" on transients (drums) at extreme speed ratios. Below 2× speed change the artifacts are typically inaudible.
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.
