Help please!
I'm looking for a method of changing/synthesizing/dividing an audio signal down to lower frequencies while retaining its amplitude and phase.
A division of 5 - 10 is desired.
The ideal circuit would represent 100hz as 10hz, 1khz as 100hz, 10khz as 1 khz, etc.
While the input would be a random audio signal such as music or room noise, the output would need to accurately follow the amplitude of the input at the lower frequencies without any delay or phase shift.
The output waveform and signal quality is not extremely important.
Any ideas are greatly appreciated.
