Process for the production of a sound recording and a device for carrying out the process

Claim 1

A process for the reproduction of a sound recording using headphones as the reproduction device, comprising connecting between the sound carrier and the reproduction device a reverberation reproducer, producing reverberation reflections within a period of approximately 50 ms, at least some of which if triggered by pulses occurring simultaneously in both channels of the sound carrier are delivered at time intervals from each other so that they are perceived by the listener as sound-intense single reflections by themselves, triggering at least some of the single reflections consisting of two pulses by a direct sound pulse from a channel of the sound carrier and of which two pulses the first is emitted over the channel of the reproduction devices that is assigned to the corresponding sound carrier channel and the second is somewhat weaker and is emitted over the other channel of the reproduction devices with a time delay with respect to the first pulse of approximately 0.2 to 1 ms the reverberation reflections are damped in dependence upon the sound frequency, the production of a mono-single reflection being effected by both input terminals (404, 406) being connected to a common first delay device (452, 456) whose output is connected, by frequency-dependent damping filters (H, B, V), a line branch (460) and adding elements (node amplifiers 408, 410), to both output terminals (408, 410), and whose delay is greater than the respective delay of at least two first delay devices (422, 436) which participate in the production of single reflections consisting of two time-separated pulses.
