Everything you need to know
Does speeding up the song make it sound metallic?
No. Our audio engine utilizes high-precision fractional resampling to ensure vocal clarity and punchy transients across all speed ranges.
Does the pitch change together with the speed?
Yes. Speed and pitch move together the way they do on a turntable, which is exactly what gives Nightcore its bright vocals and Slowed edits their deep tone.
What formats can I export?
You can download your processed remixes in universal MP3 and lossless WAV formats.
