AB  - Independent component analysis is tested as an approach to reduce the effects of instrument bleed in a multi-track audio recording. Two microphone techniques are examined for a case with two sound sources. The first technique uses each microphone facing a separate source, while the second uses both microphones facing the same source. The separation of the microphones as well as polarity is altered to observe the effects. Both techniques are tested using a simulation as well as with a physical experiment. The first technique is shown to be effective less than 50% of the time with minimal bleed reduction. The second technique is shown to be effective between 68–96% of the time and can have an average bleed reduction of up to 2 dB with instances up to 4.6 dB.
