Remix Lab
Bring your own sound. Reshape it.
A small sampler and sound-design bench that runs entirely in your browser. Load a lossless file you have the rights to use, then loop, stretch, scatter, slice, filter and record it.
Only remix audio you have rights to. Nothing leaves your device. Files are read and decoded inside this tab; there is no upload, no account and no server copy. This site hosts none of Mariam Wallentin’s recordings and offers none to remix — bring your own files.
Lossless only: WAV, AIFF or FLAC. MP3, AAC, M4A, OGG and other lossy formats are not accepted.
Drop a WAV, AIFF or FLAC file here
or choose one from your device — or try the built-in demo loop (original synthesized tones).
