Skate Program Editor

Nothing to install and nothing to sign up for. Your music never leaves your computer — the files are read straight from disk by the browser and stay there.

[!IMPORTANT] Built with AI, for my own use. The code here was written with heavy AI assistance. I needed to cut a program and did not want a digital audio workstation to do it; it is public in case it saves someone else the same afternoon.

There is no team behind it, no support, and no undertaking to fix anything or to keep it working. Use it at your own risk — and before an entry deadline, play the exported file end to end rather than trusting that it came out right.

Why

Program music is a handful of cuts joined together and timed to the second, but the usual options are a full digital audio workstation, which is far more than the job needs, or paying someone else to do it.

This does the one job: cut, order, blend, check the length, save the file. Every choice in it follows from that — plain language instead of studio vocabulary, a timer sized for the thing you actually have to hit, and no feature that a sequence of cuts does not need.

What it does

• Trim each song by dragging the ends of its waveform, or with I and O
• Reorder by dragging the blocks
• Blend one song into the next, or fade in and out
• Line up this join — one button nudges a cut by up to a couple of seconds to somewhere the music can take it. With a steady beat it puts both songs on it, which is what stops a blend sounding like a stumble; where there is no beat, as in piano and much orchestral music, it finds the end of a phrase instead — and it tells you which it did
• Even out the volume — one button sets every song so they sound about equally loud without letting any of them distort, and a per-song slider adjusts it by hand afterwards
• Watch the clock — a big timer that turns green inside the allowed window for your event, and tells you exactly how far off you are when you're not
• Flag weak audio before you commit to it, with a plain Good / Fair / Low verdict rather than a bitrate you have to interpret
• Hear a join before you commit to it — one button plays the few seconds either side of a cut
• Save your work as a small readable file recording the edit, so you can come back and adjust it rather than starting over
• Export to MP3 or WAV, with a warning first if the program would come out too loud to store cleanly

Everything runs in the browser tab: decoding, playback, mixing and encoding. There is no server and no upload step.

What it needs

Any current Chrome, Edge, Firefox or Safari on a computer. The page tells you if something it needs is missing rather than failing quietly.

It works on a tablet but warns you first: trimming by touch is fiddly, and decoded audio is uncompressed — roughly 90 MB of memory per four minutes of stereo — so a few long songs can exhaust what a mobile browser allows.

No account, no network beyond loading the page, and no server. On Chrome and Edge the editor can also offer your songs back after a reload, so loading a saved project is one click instead of finding each file by hand; Firefox and Safari have no such facility and there you add the files again, as always.

Program lengths — check them yourself

The event list covers ISU singles, pairs and ice dance, and U.S. Figure Skating free skate and short program levels. These times are a convenience, not an authority. Required lengths are set by the governing bodies and do change between seasons. Check your level against the current rulebook, or with your coach, before an entry deadline.

Issues and pull requests are welcome, with no promise about when they get looked at — see CONTRIBUTING.md for how to set up and what any change has to keep working. Found a security problem? SECURITY.md says where it goes.

If an event length here disagrees with your rulebook, that is the most useful issue you can open: there is a template for it, and a link to the document is the part that matters.
