Parametric Representation of Complex
Sources in Reflective Environments

Dylan Menzies

AES 128 Convention  London May 2010

The following recordings compare different methods of producing a stereo image of a recorded source with added artificial reverberation, using a single mic or two mics pointing at the source 90 degrees apart. The proposed method is 2 mics with two reverbs as described in the paper. The reverb used was Waves TrueVerb. The ProTools session used is available here:  complexSourceReverb.ptf

bamboo flute      mono     2 channel    2 channel 1 reverb     2 channel 2 reverbs

blues harp     2 channel 2 reverbs    2 channel  stereoreverb

shaker    mono     2 channel 1 reverb   2 channel 2 reverb

key:

mono - just one mic channel panned to centre

2 channel - channels are panned close together near centre.

2 channel 1 reverb - channels are panned close together near centre. Both send 1 reverb.

** 2 channel 2 reverb - channels are panned close together near centre. Each sends to two reverbs that differ slightly in the distribution and strength of the early reflections. On their own they sound very similar to each other.

2 channel stereoreverb - channels are panned close together near centre. They send a stereo reverb similar to above.
