Why don’t mp3 players have a crossfeed circuit? When listening to music through speakers each ear hears both channels, with the sound from the further spear delayed a bit and slightly lower in volume. Why don’t mp3 players have a circuit to mix some of the other into each channel, with the volume and delay that the user can set?
If a crossfeed circuit is too expensive to put in mp3 players, then why aren’t new recording done in a binaural manner using a dummy head? It seems like the majority of listening is done through headphones now.
