Sample editor

Clean up a recording without leaving the browser: trim the silence off the ends, tidy the edges with fades, normalize to a peak or loudness target, remove DC, stretch time without changing pitch, render a crossfaded loop — then export a fresh WAV. As a bonus, find the transients and slice it like the classic beat slicers: tweak each slice (gain, pitch, reverse), rearrange the order and render the chop, and the slices leave as a .zip of WAVs with an optional MIDI groove and an SFZ patch a sampler opens directly. Nothing is uploaded; the audio never leaves this page.
