ear training may also be required to get you more attuned to pitch.Good answer
But it does, also, sound like you've grown accustomed to pitching your voice flat, so. The single most important thing is to get yourself some headphones, so you can actually hear - properly - your voice as you record. Whatever sampling rate Reaper is playing them back at, is also the same rate at which it's recording and playing back your vocals. In particular, if you're not using headphones, then you're mostly hearing your voice as it resonates through your body, rather than as it travels through the air.īut the answer, I'm sorry to say, is NOT some play-back anomaly caused by using mp3. (Cheap amplifiers don't make you sing flat nor do old soundcards!) Of the possible reasons mentioned both 1 & 3 point to the fact that you are, in fact, singing flat - but that your recording set-up is such that you don't notice it while you're doing it.
