What is LevelCloud?

This is an online (web-based) loudness analyser and processor, compliant with EBU R128 and ATSC A/85 standards. If you upload an audio file, we'll give you a download link to your EBU or ATSC compliant audio file. If you'd like to process more files, we'll ask you to leave an email address and we'll add the files to a queue.

We believe music and media should should always sound great, no matter the budget and the facility. This site is created as an easily accessible first introduction to loudness and loudness normalisation.


We can handle AIFF, WAV, MP2, MP3, FLAC, MOV, MP4, MXF and many more file types. Currently the maximum file size is about 500mb. You can upload 3 files per day and files will be kept for a day. We'll remove the files after you've downloaded them.

Privacy & warranty

We do our best to keep this site compliant and reliable but we can't take any responsibility. Your files will be deleted after one day and will not be shared with third parties, analysed or used for anything else.
