About this report
This is a report for professionals with a suite of tests for line output devices. Alternative version of the report for "dummies" in development.
One device can have multiple reports in different modes and with different a suite of tests.
A suite of tests for the line-out can be used for headphone or speaker output if in this mode it is possible to use the device as a source for connecting an external amplifier or if such a test suite can give more information about the implementation of the DAC in the device.

*Center channel headphone is received by averaging between left and right channels
Test conditions
- Measured by RAA with ADC from E-MU1616m
- During tests RAA measuring complex was used galvanic isolated power transformer and was excluded the effect of ground loop in the spectra

Brief information
During the test, played a pulse with a sampling frequency of 44.1 kHz and the recording is performed with a sampling frequency of 192 kHz / 24-bit
The impulse response can identify the type of digital filter DAC.
