Abstract
An apparatus and method for joint music production wherein a remotely separated plurality of musicians are joined by phone lines of a public telephone system. The public telephone system has a signal frequency cutoff limiting transmission to a low range which is incompatible with music. Each of musicians produces a local music signal (MSL) with full audio range. This signal is impressed on the public telephone system which creates a low-end outbound music signal (LEL). Also, separately, the MSL signal is filtered through a first high-pass filter and mixed with a mixer signal to produce a sum/difference signal (SDL). The SDL signal is impressed onto the second phone line of the public telephone system as a high-end outbound music signal (HEL). A second mixer circuit receives at least one remotely produced sum/difference signal (SDR) and the mixer signal and this is again filtered to obtain the high end signal only (HER). The HER signal and the at least one remotely produced low-end signal (LER) are joined to produce the remotely originated limited band pass music signal which is summed with the MSR signal for listening to the composite music signal.
