Does the sample rate make any difference when uploading, or does MySpace compress to 96kps regardless?
The sample rate doesn’t change from the uploaded track (doesn’t undergo any compression, like videos will). For songs, the standard parameters are 192 Kbps, 10 mb max file size, and MP3 format. A song uploaded with a lower sampling rate (say 92, or 128 Kbps) will have lower audio quality on the website than one that is uploaded at 192.
