is available in high definition 24-bit audio
Where the version name says (wav24) it means the download is a
.zip file containing two wav files: One file at High Definition 24-bit audio,
and one file downgraded to normal CD-quality (16-bit, 44.1 khz).
You will only see the HD logo (by which we mean 24-bit sound) on music that
was recorded, mixed and mastered in 24-bit. We never "upsample"
16-bit material to 24-bit.

music and some technical details, please see this
