In order to complete measurements, connect your phone or tablet headphone/line-out JACK to a computer with a high quality soundcard line-in then record the output manually. By using this app instead of playing samples through a vendor or third-party music player you can be sure no signal processing is done by the player. If the manufacturer adds audio effects, you’ll be able to spot them with confidence through measurement. Without additional (like SRS, Beats audio) processing and if digital volume is maxed out, DAC will be fed by un-altered PCM data. Measurement accuracy tips: * Ensure any re-sampling is disabled on your computer by setting sample frequencies to 44100 Hz. * Record using the maximum resolution (in general, 24bit) of your sound card's ADC. * Run your device on battery, not plugged on charger or USB. * Take care of using appropriate and consistent input and output levels.
