Measurement with cell phone

Tip: Get quick an acoustic frequency response measurement via mobile phone and RTA app (free mode sufficient) plus CD or DvD "Pink Noise" signal. Use the app: 

  • iOS app "Spectrum"
  • Android app "RTA Analyzer" 
Or use a FFT app to analyze distortions with sine or IMD signals.
Tip: You can use external microphones, to improve the measurement accuracy.
