Item was changed: ----- Method: MixedSound>>mixSampleCount:into:startingAt:leftVol:rightVol: (in category 'sound generation') ----- mixSampleCount: n into: aSoundBuffer startingAt: startIndex leftVol: leftVol rightVol: rightVol "Play a number of sounds concurrently. The level of each sound can be set independently for the left and right channels."
