Description

Elektroakustische Bandmarkierung Die Erfindung betrifft eine elektroakustische Bandmarkierung, bei welcher die Tonaufspeicherungsspur unter Schwächung der ursprünglichen Aufnahme durch eine nachträglich aufgebrachte Aufzeichnung überlagert wird.Electroacoustic Tape Marking The invention relates to an electroacoustic tape marking Tape marking in which the sound storage track is weakening the original Recording is superimposed by a subsequently applied recording.

Es ist eine Einrichtung bekannt, bei welcher einer Tonaufzeichnungsspur unter Schwächung der ursprünglichen Aufnahme eine zweite Aufzeichnung überlagert werden kann. Hierbei wird mit Hilfe der sogenannten »Tricktaste« nur eine teilweise Löschung des ursprünglichen Textes vorgenommen. Es ist ferner bekannt, einer Tonaufzeichnungsspur eine Signalspur zu überlagern, die dazu dient, ein Relais zu betätigen. Bei diesen Einrichtungen wird zur Herstellung des Signals ein besonderer Niederfrequenzgenerator benötigt. Die Erfindung will diesem Mangel abhelfen. Erfindungsgemäß wird die Signalspannung von einer in dem Gerät bereits vorhandenen Signalquelle, z. B. dem auf Hörfrequenz umschaltbaren Löschgenerator, dem Motorkommutator oder der Netzfrequenz entnommen.A device is known in which a sound recording track a second recording is superimposed, weakening the original recording can be. Here, with the help of the so-called »trick button«, only a partial Original text deleted. It is also known to have a sound recording track superimpose a signal track that is used to operate a relay. With these A special low-frequency generator is used to produce the signal needed. The invention aims to remedy this deficiency. According to the invention, the signal voltage from a signal source already present in the device, e.g. B. the listening frequency switchable extinguishing generator, taken from the motor commutator or the mains frequency.

PATENTANSPRUCH: Elektroakustische Bandmarkierung, bei welcher die Tonaufzeichnungsspur unter Schwächung der ursprünglichen Aufnahme durch eine nachträglich aufgebrachte Aufzeichnung überlagert wird, dadurch gekennzeichnet, daß die Signalspannung von einer vorhandenen Signalquelle, z. B. dem auf Hörfrequenz umschaltbaren Löschgenerator, dem Motorkommutator oder der Netzfrequenz entnommen wird. In Betracht gezogene Druckschriften: Deutsche Patentschrift Nr. 532 904.Claim: Electroacoustic marking tape at which the sound recording track is superimposed by weakening of the original recording by a recording subsequently applied, characterized in that the signal voltage from an existing source signal z. B. is taken from the extinguishing generator that can be switched to audio frequency, the motor commutator or the mains frequency. Documents considered: German Patent No. 532 904.
