QLoud is a tool to measure loudspeaker frequency response and (yes!) distortions.
Find it here:

Changes:
- harmonics (distortions) plotting is added,
- as a result, noticeable part of common code was refactored/rewritten.

If you have a sound card with good DAC and ADC, you can plot harmonic
distortions for another audio equipment, say, for your power amplifier -
cited screenshot has also harmonics plot for loopbacked sound card.
