Whether you're uploading an audition for a project or a demo to your profile, please be sure that your audio file is in the following format:
- File smaller than 3MB
- Sample rate: 44.1kHz
- Bit depth: 16 bit
- Channel: Mono
- Bitrate: 96 or 128 Kbps
If you get an error while uploading, please be sure to check these parameters! Most of the time, errors occur because of incorrect file formats/parameters.
Converting to mp3 format using these parameters depends on the specific software you are using. If you're unaware of how to convert file formats, or are unfamilar with these terms, we highly recommend that you get coaching, as these are terms that you will be expected to know. Audio editing and knowledge is required prior to auditioning and offering yourself for work.
What is the difference between formats?
MP3: An mp3 is a commonly used compressed audio file format. Because it is compressed, the file size is usually quite small. Despite that, the sound quality is pretty good, assuming you are using a high enough bitrate. The higher the bitrate on an mp3, the better the sound quality and the bigger the file size. 128kbps is standard for broadcast, but the best high quality bitrate commonly used in professional audio is 320kbps. Because mp3 is a compressed format, it is best to do all editing in an uncompressed format, such as wave or AIFF. Once you are done editing, do a final save in mp3 format.
WAV (PCM): A wave file is an uncompressed audio file. Due to the fact that it is uncompressed, it is usually much bigger than an mp3 and higher quality. It is used mostly on Windows systems, but can be used on a Mac as well.
AIFF (Audio Interchange File Format): Aiff is also an uncompressed file format. It is also high quality and tends to be very large in size. This file format is mostly used on Apple systems, but can be used on Windows as well.
