Creator Hub Audio Upload Rejected and Incorrectly Identifies Audio Length

[Synthris]

When uploading audio files through the Roblox Creator Hub, the system incorrectly identifies the file length and immediately moderates (denies) the upload. The issue persists across multiple upload attempts. If it happens to be against Roblox’s TOS, my account does not receive any moderation message. The audio also cannot be played.

Steps to Reproduce

1. Roblox → Create
2. Creator Hub → Creations
3. Creations → Development Items
4. Development Items → Audio
5. Upload asset

Expected behavior

The audio file’s length is correctly identified and the audio proceeds into the Roblox system for moderation.

Try re-exporting the audio, or saving it under a different format.

Back when public audio still existed and you had to pay to upload, people used to use a bug in audio compression + how Roblox interprets it so longer content would appear shorter (and in turn cost less to upload)
I’d imagine it may be a similar issue here, and it’s just denying the upload because it might be able to detect that these days.

I followed your advice and converted the file to .ogg.

The file was pending moderation, as expected.

However, the audio was then blocked for IP violation, which is unusual as the original mp3 file was left alone. I would try other audio formats, but I don’t want to push the system and receive an automatic moderation action against my account.

Roblox removes tracks instantly which are remotely close to the fingerprint of already existing track. It’s not really avoidable nor appealable :c.

I don’t want to push the system and receive an automatic moderation action against my account.

Those don’t affect your account, but at the same time it would be pointless for you to retry if the system is just going to reject it, over and over.
