A list of raw multitrack projects which can be freely downloaded for mixing practice purposes. All these files are presented as ZIP archives containing uncompressed WAV files (24-bit or 16-bit resolution and 44.1kHz sample rate), without any effects or processing. When importing them, just make sure all the track files start at exactly the same moment in time within your DAW project. In addition to the Full Multitrack packages, there are also many quick-download Edited Excerpt versions (usually featuring the song's biggest chorus) which provide 'bite-sized' mixing assignments well-suited to classroom use. In both cases a preview mix is provided for easy auditioning while browsing through the list.
