For example, If I have 3 recordings of 3 different people on 3 different microphones...how do I get the 3 recordings to sound like they were recorded in the same room even though they were recording in different environments. I need these 3 recordings to blend seamlessly for video/film.
Is it as simple as applying noise cancellation or reverb on all 3 tracks?
Any help appreciated.
noise cancellation won't work all that well as the noise signature is not what you are trying to remove, you are trying to remove the reverb/room signature which without an impulse for the room is next to impossible
eq to cut out low end rumble and high end flutter would work to a degree but would also colour each recording further
- applying a telephone bandwidth filter extended an octave either side would probably be best
- i.e. instead of 300Hz-3300 Hz use 150Hz-6600Hz as the upper and lower limits of the filter
-- adjust the lower limit upwards a bit if there is still too much rumble, remembering that male voices have a fundamental between about 80Hz and 131Hz and female voices have a fundamental between 160Hz and 262Hz
-- adjust the upper limit up or down depending on the part of the room signature that exists either side of the given the freqs
- roll off at 18db/octave or 24db/octave
after eqing each vocal to get the flattest sound from each,
you might compress each vocal to bring them into the same range - you are trying to get them to be within the same dynamic range
not the same level
you might then consider adding just a touch of reverb to put them all into the same space
