Dear REW community, A hopefully simple question! Are frequency sweeps and accurate way to match the level of left/right stereo speakers? To explain: I usually calibrate my speaker levels using pink noise and the SPL meter in REW (together with a handheld SPL meter as a double-check), but I always find SPL meters to be a bit ‘jittery’ and imprecise (even when C-weighted slow). Recently, when reviewing some REW measurements of my room, I noticed that the left-side speaker frequency response was consistently 0.5dB lower than the right-side speaker response (when viewing the All SPL graph). This was especially clear when viewing both plots at 1/1 or 1/3 smoothing). So I decided to correct it by tweaking the left speaker output level and then running frequency sweeps to compare it against the right speaker response until they matched. Are there any potential flaws in this method? It seems like an obvious and very easy solution to me, especially when making minor adjustments that would otherwise be difficult to gauge on an SPL meter. Unless I’m missing something? Thanks in advance for any clarity PS: loving the recent REW updates! Great work John.
