From the project
A simple circuit to allow merging stereo input channels
A simple circut to allow merging stereo input channels.
When listening with headphones, though, there is no way for sound from the left channel to reach the right ear and vice versa. This often feels very unnatural, because, for example all percussion instruments might be on the right, while the melody is only getting to the left ear.
This little board allows cross-fading the left and right channels to keep the separation, but have a little of each channel bleed over to the other side.
