This subsection addresses how the tuner can use the smart amp tuning elements of input gain, EQ, DRC, and smart amp to match the pink noise response of a reference sound source. At this point the user must implement the EVM or prototype device, PPC3 GUI, a microphone, any audio player software, and an audio analysis software tool, such as RoomEQ Wizard.
Use a prepared playlist of reference pink noise audio tracks here starting with 0 dBFS or –6 dBFS and decreasing to –78 dBFS. Most audio processing software can generate these audio tracks. If the reference device has more than one speaker, the user must utilize a left-only or right-only track to avoid measuring the stereo response of the device. Alternatively, ask the TI audio engineer to provide these files. After acquiring these tracks, copy the files to the reference device and open the tracks in an audio player on the PC connected to the target device. TI recommends to make a playlist from the noise tracks on each device.
