Splice Re-Mixes the Music Mashup.

A new social music mixing site is re-thinking interactive audio. Splice, which is still in beta, is a community site that encourages users to submit raw sounds. Users can then build songs out of each other’s sounds. Each creation can be remixed, rearranged, deconstructed and completely re-worked by anyone else in the Splice community.

Splice’s coolest feature is the browser-based sequencer. Songs are assembled and mixed without ever leaving the browser. You can also see details about the users who contributed each track as you mix.

Once you log in (you have to register and build a profile to use the service) you can browse through sounds and completed songs, all submitted by users. People have posted beats, drones, piano loops and guitar arpeggios. There are even some truly odd recordings, like spoken poems and children babbling. Splice accepts all of the popular music formats: WAV, AIFF, MP3, Ogg Vorbis and even FLAC. Each sound is tagged and most are marked with a BPM value. Songs can be opened in the sequencer and tweaked. The mixer will also auto-adjust the BPMs of your sounds so that the beats match up. Add or subtract sounds, slide some faders, then publish your work.

Everything produced by the Splice community is released with an Attribution Creative Commons license. Any song on Splice can be downloaded as an MP3.

If you’re new to Splice, you might want to watch the short demo video, which will show you the basics. The site requires Flash Player 9 to use. Splice also runs best in Firefox.

Give it a whirl, make some noise.
