Spreaker Help Center

You can upload files in the following formats:

• mp3
• wav (mp3 or PCM encoding)
• AAC
• 3gp / 3gpp
• mp4 / m4a

with each file being no more than 200MB. We are working to support additional codecs & file formats. Check this page or our user forum to find out when new formats will be supported.

To ensure maximum audio quality even with low bandwidth, Spreaker mixes music and sound effects Server-Side. Your Personal Music Library is a Storage Space "in the cloud" where you can upload music tracks, jingles and sound effects to be used during your broadcasts.

• Check your internet connection. 

Sometimes, upload interruptions can be blamed on a weak or spotty internet connection. We recommend using a cable connection rather than WiFi, particularly for larger files, because even a short WiFi connection timeout can interrupt the upload. 
• Give another browser a try. 

If uploading works in another browser and not in the one you usually use, check the add-ons/extensions or proxy settings you have enabled on your usual one.
