Stereo me­ter­ing

If you like to back up what you’re hear­ing with vis­ual feed­back, you can al­ways turn to a ded­i­cated stereo me­ter plugin.

A go­niome­ter dis­plays a sig­nal’s width (ie, stereo bal­ance and phase in­for­ma­tion) on a cir­cu­lar or semi­cir­cu­lar in­ter­face, with the ver­ti­cal axis rep­re­sent­ing mono and the hor­i­zon­tal axis dis­play­ing stereo con­tent. A 100% mono sig­nal will be dis­played as a sin­gle ver­ti­cal line, and stereo in­for­ma­tion that’s rea­son­ably in phase will ‘fluff’ out­wards and pop­u­late the in­ner marked 45-de­gree ‘safe zone’. The more out of phase the stereo con­tent, the more it’ll breach out­wards into the side ar­eas. If your sig­nal strays too far into the ‘dan­ger’ re­gions for too long, your ma­te­rial is too out of phase, and may be lost when summed to mono.

A phase cor­re­la­tion me­ter, mean­while, is a sim­ple hor­i­zon­tal or ver­ti­cal bar me­ter. Its val­ues range from +1 (rep­re­sent­ing a ‘fully cor­re­lated’ or cen­tred sig­nal) to -1 (com­pletely out of phase). Again, if your sig­nal sits in­side the ‘dan­ger’ mi­nus area for too long, you may need to re­visit the sound.
