In this paper, we enumerate the specific advantages of using a sinusoidal representation for scaling of audio signals. Most existing systems scale signals using time domain algorithms. Here, we discuss a frequency domain technique to scale signals by any desired factor. We also compare the computational savings of the proposed algorithm with traditional time domain methods.
