What plug-in?
Heavy metal is usually really compressed anyhow.
I don't understand why this is in mono though.
It's possible he's used a mono version of a compressor plugin on the master mix. If he used The Tokyo Labs feedback Compressor II, for instance, they have four versions - the Mono 32-bit, the stereo 32-bit, the mono 64-bit and the stereo 64 bit. If you use the mono version on the master bus it will cause the whole mix to output in mono. Worth checking.![]()
To my ear, the whole thing sounds overly bright for the genre...YMMV
