Freesound Forums

Greetings,

I hope this is the right place to bring this up, but I've uploaded a few sounds that were made to loop without clicks or the restarting being audible, but I have received comments which state that my sounds don't loop properly, and upon trying the preview button, the sound loops quite badly.
Is this the expected behavior, i.e., are most users aware that the preview function can't be trusted to judge loops like that?

I doubt it's something that Freesound can technically fix easily.
Explain it in the description. "Download is seamlessly loopable (even if preview isn't)"

(Thread more helpful to others if in "Bug Reports, Errors and Feature Requests.)

Thank you for the reply.
Unless I'm mistaken, I remember seeing that Freesound compresses previews to mp3 to save space, so I did a local test, seems like both Chrome and Firefox don't loop mp3 files properly.
I will consider putting up disclaimers, but it may be good to consider converting to ogg or flac instead?

I don't think it makes any difference what format is used for the file upload. Previews are always reduced to mp3 to save overloading bandwidth when streamed. The glitch most likely occurs at the server end before it gets decoded in your browser anyway.

I think its a known limitation of mp3s - I think the issue was that they come 512-or-some-such byte chunks, and it gets padded with silence to at the ends

There's a discussion here.
