The method includes: selecting weights for each of a plurality of harmonics corresponding to a fundamental frequency; using the selected weights to synthesize a precursor audio signal from only the fundamental frequency and the plurality of harmonics; compressing the precursor audio signal one or more times to provide an audio signal which has a crest factor that is below a predetermined threshold.",
