The thing I don't get is, do people really release recordings with the
phasing wrong?
I agree that signals being out of phase between channels is blindingly
obvious, but I believe P Floding is talking about absolute system phase, ie
switching the entire phase of the system.
The feature request only makes sense after your system, and its speakers
are right.
I've come across this mainly when working with live sound systems when micing
transient sources like drums. Ideally you want your initial wavefront from
the drum source to be reproduced by a "push" with the speaker cones in the
system
Right, a kick drum should start out towards the listener. The speaker
cone should move forward.
As Alex wrote, after all the EQ and effects that get done to most
modern recordings, the phase gets all wacko. It is
impossible (almost? totally?) to do EQ without introducing phase artifacts.
As a plugin or effect, it is pretty easy, just flip the data.
I forget the details of PCM value encoding, I think they are
just 0 to 2^16-1, so you have to arithmetically change it.
Still just one byte operation per 16 bit sample.
