How to Troubleshoot a Failed DJ Edit

A DJ edit in Club Ready Music fails in one of a few known ways, and each has a direct fix: the upload is refused because the file is over 60 MB or uses an unsupported extension, the server replies Audio tools are not available on this server yet, the status goes to Failed with Analysis failed, the stem split on the server errors out, or the page says Still working on this one because you pressed Build the DJ edit while the edit was still Analyzing, Separating or Mixing. A second group of problems produce a Ready edit that sounds wrong, usually half or double BPM or a misplaced first beat. Work down the list in order and you will find the cause.

Steps

1. Read the status and the message

The right panel shows the status: Analyzing, NeedsConfirm, Queued, Separating, Mixing, Ready, or Failed with an error message. The message is the diagnosis. A refusal before any status appears is an upload problem. Failed during Analyzing is Analysis failed. Failed during Separating is a stem split failure. A message about audio tools is the server, not your file. Note which one you have before changing anything.

2. Fix a refused upload

The drop zone accepts .mp3, .wav, .m4a, .flac, .aac and .ogg up to 60 MB. A 24-bit WAV of a long song, or a FLAC of an album-length mix, can exceed that. Convert the file to a 320 kbps MP3 or a 16-bit WAV, or trim silence from the ends, and check the size before dragging it in again. A file with an unusual or missing extension is refused even if the audio inside is fine, so rename or convert it so the extension matches the content.

3. Wait out Audio tools are not available

If pressing Upload & analyse or Build the DJ edit returns Audio tools are not available on this server yet, the server's audio worker has not finished starting. Your file is uploaded and nothing needs redoing. Wait about a minute and press the button again. If the message persists for several minutes, leave the page open; the edit stays listed under Recent edits and the worker will pick it up when it is up.

4. Recover from Analysis failed

Analysis failed means Club Ready Music could not read a usable grid from the file. The usual causes are a corrupt or truncated file, a file that is mostly silence or speech, or a format that decoded badly. Re-export the song as WAV or MP3 320 from your source, confirm it plays start to finish in a normal player, and upload again. Detection works best on steady electronic and pop tracks; a free-tempo intro of a minute or more can also defeat it, so a version trimmed to the beat section is a good second attempt.

5. Retry a stem split failure

Club Ready Music runs the stem split on an external service, and a Failed status during Separating means that call did not return stems. It is almost always transient. Press Change settings & rebuild, keep the same settings, and build again; the song is still on the server and does not need re-uploading. If a second attempt fails on the same file, re-encode the file as a 320 kbps MP3 or 16-bit WAV, since very large or unusually encoded files are the ones most likely to trip the split.

6. Understand Still working on this one

Pressing Build the DJ edit while the status is Analyzing, Separating or Mixing returns Still working on this one. It is not an error, it is the page refusing to queue the same edit twice. Wait for NeedsConfirm to confirm the grid, or for Ready to hear the result. The worker handles about 3 edits per phase at a time, so if you queued several edits, the one you are watching may sit at Queued for a while before it moves.

7. Fix an edit that is Ready but wrong

A Ready edit with a drum loop at half or double speed means the detected BPM was half or double the real tempo. Press Change settings & rebuild, use ½ or ×2 on the BPM field, confirm with ▶ 4 bars and build again. An edit whose intro lands late or whose first downbeat has a doubled kick means First beat (ms) was off; adjust it in 10 ms steps, confirm with ▶ 4 bars and rebuild. If an edit is noticeably quieter or less dense than the LUFS chip suggests, the mastering stage fell back and stored an unmastered WAV. Rebuild it at the same settings and the loudness pass runs again.

Tips

• Keep the Club Ready Music page open while an edit builds. The status panel tells you exactly which phase failed, and that saves guesswork.
• Confirm the grid before building. Most wrong-sounding edits are grid errors you could have heard in four bars.
• Upload MP3 320 or 16-bit WAV for anything near the 60 MB limit. A 24-bit WAV of a six-minute song sits right at the edge.
• Rebuilds never need a new upload. Change settings & rebuild reuses the song on the server, so retrying costs you a click.
• If the whole queue is stuck at Queued for many minutes, it is the server side, not your files. Come back later and the edits will have progressed.

Common problems

• The upload bar fills and then nothing happens. The file was refused for size or extension. Check it is under 60 MB with a supported extension and try again.
• Every build attempt says Audio tools are not available on this server yet. The audio worker is starting. Wait a minute, press Build the DJ edit again, and leave the edit in Recent edits if it still does not go.
• Analysis failed on a track that plays fine. The file decoded badly or has a long free-tempo opening. Re-export as WAV or MP3 320, or trim to the beat section, and re-upload.
• The edit is Ready but sounds like a slow-motion drum loop. BPM was detected at half tempo. Press ×2, confirm with ▶ 4 bars and rebuild.
• The edit is Ready but much quieter than −8 LUFS. Mastering fell back to an unmastered file. Press Change settings & rebuild with the same settings and let it run again.
