| Maximum slew rate typically found in music/voice |

| TimFox:
Slew rate is relevant to distortion, which may increase with signal level non-linearly. Harmonic distortion and intermodulation distortion are different ways to quantitatively measure the same non-linear behavior. 3rd-order intermodulation products will not be affected by a low pass filter, since they are close to the two test-tone frequencies. Bandwidth is a measure of a linear system. |

There is a reason that bandwidths are often divided into two distinct categories: "small-signal bandwidth" and "full-scale bandwidth". The former is where slew rate limiting doesn't occur. |
| TimFox:
The latter is often called “full-power” bandwidth on data sheets. |
