The preferred format is a 192 kbps MP3.
For the sake of file size, please don’t make your file much larger; for the sake of quality, please keep it above 128 kbps. We find 192 kbps provide a nice mix of compact size and adequate quality.
Please do not send or post files in lossless formats (flac, ape, aif, etc.); MP3 is what we’re looking for here (unless you’re sending a CD for us to rip).
