Frequency scaling of audio signals

I have an audio signal x[n], whose frequency varies over time. It's FT is X[k]. I want to reconstruct an audio signal (x_hat[n]) from X[k] such that, at any given time:
frequency_of_x_hat[n] = log10(frequency_of_x[n])
i.e. the frequencies are compressed logarithmically. Any idea about how to do this? Thanks.
