Electro-acoustic audio reverberation device
First Claim
1. An apparatus for processing audio signals into and out of an acoustic reverberation element, comprising:
- memory including instructions stored thereon; and
a processor, that in response to execution of the instructions causes the apparatus to;
upwardly pitch transpose an audio signal by a factor resulting in a pitch-transposed audio signal;
communicate the pitch-transposed audio signal to the acoustic reverberation element; and
downwardly pitch transpose a resultant reverberant signal from the acoustic reverberation element by the factor.

Abstract
Disclosed is an audio reverberation apparatus. The audio reverberation apparatus interacts with or may include a mechanical or acoustic reverberation element. An audio signal is pitch transposing upward and applied to the mechanical or acoustic reverberation element. The resulting audio reverberant signal retrieved from the mechanical or acoustic reverberation element is pitch-transposed downward by the same factor as the upward pitch transposing. This results in the mechanical or acoustic reverberation element requiring smaller dimensions in comparison to a mechanical or acoustic reverberation element where a non-pitch-transposed audio signal is applied.

14. An apparatus used for processing audio signals, comprising:
-
a processor configured to separate an audio signal into portions and upwardly pitch transpose the audio signal by a factor, resulting in a plurality of pitch-transposed portions; an acoustic reverberation element, the acoustic reverberation element responsive to the plurality of pitch-transposed portions and includes an output with a resultant reverberant signal; and the processor configured to temporally arrange successive reverberant portions of the resultant reverberant signal, and downwardly pitch transpose temporally arranged reverberant portions by the factor. - View Dependent Claims (15, 16, 17)
