Urlanda Mixer
A multitrack mixer running in the browser, built to cut a recorded concert into songs and export them.

Urlanda Mixer is a multitrack mixer that runs entirely inside the browser, with nothing to install. You drag audio files in and they land on the timeline.
Mixing
It carries what you would expect from a desk: transport with millisecond precision, timeline zoom, a master fader in dB, per-track control, effects and a stage view. Sessions can be saved and reloaded, and there is direct recording.
Cutting the concert
This is where it departs from a generic mixer. Song markers let you split a whole gig recording into individual pieces, and you then export each song separately or the concert as a whole.
Exporting
Export is to MP3 at 128 to 320 kbps, with configurable fade in and out and optional normalisation. All processing happens on the user’s own machine: the audio never gets uploaded.
