When reading compressed audio, the reader will resample the content to match the output format. You must use one of the output formats enumerated by the reader, so you are guaranteed that the audio can be resampled to the output format settings. Each resampling potentially affects the quality of the audio.

A practical and well-known example results from the fact that professional audio equipment uses a sampling rate of 48 kHz, but consumer audio equipment uses a rate of 44.1 kHz. Therefore, to transfer music from a professional recording to a CD, the sampling rate must be changed by a factor of: (44100 / 48000) = (441 / 480) = (147 / 160)
