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.

Claims

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.

2. The apparatus of claim 1, further comprising:

a digital-to-analog converter that facilitates communication of the pitch-transposed audio signal from the processor to the acoustic reverberation element; and
