Raw Audio with digital noise

[pyrisurfer]

I've got what seems to be a raw Audio file (48 kHz, 16-Bit, Little Endian). When I import it with Audacity however, I get a constant digital noise throuout the file.

The file can be correctly imported by the Software which created it, so it is not inherently broken. Unfortunately, that Software does not support any other lossless audio export, so I need to somehow get it to work externally.

Seems to have embedded sync word or something, consisting of the eight bytes
65("A"), 72("H"), 80("P"), 48("0"), 128, 07, 00, 00
at offsets 8 + 1928 * n

Which sounds like a 50Hz buzz...

Filter those things out, and ignore the first eight bytes as well.
I bet someone probably knows what this format is...

Thank you!

I removed these Bytes with a Hex-Editor and the noise seems to have gone. I'm going to have to test this with a longer file, because the sound is now obviously slighty shorter and might get out of sync.
