Recording
As a general rule, when an instrument just doesn’t work by itself, pair it with another instrument to perform the same melody, and pan it similarly.
- ex. Take me to the pilot does a good job of this with 2 different string parts playing the same hook melody. It thickens out the sound and makes it more believable
- So if you have a lead melody part, always ask: is this instrument doing justice to it, or does it perhaps need a hand pushing the melody?
Phasing
"phase" describes how in-sync soundwaves are with each other.
- how off-set the waves are with each other can be described in degrees
- 0° means perfectly in phase; 180° means out of phase.
- when out of phase, the 2 soundwaves will cancel when mixed together, making no sound ("phase cancellation").
- when in phase, the 2 soundwaves will reinforce each other and the result will be louder.
- 0° means perfectly in phase; 180° means out of phase.
The phase cancellation between two signals matters more for lower freqency sounds.
3-1 principle
dispelling misconception about 3-1 principle
To avoid phase cancellation, Microphones should never be within 3x the distance that the microphone is from the sound source.
- ex. If we have a microphone 1 foot away from the strings of a piano, any additional microphones should be at least 3 feet away from the first microphone.
- note: this seems to be contradicted by the Reddit explanation above, so take it with a grain of salt
