The Audio Files page defines the audio file played by PDM II during Insert Build Mode or Overkill Dump Mode.
Files are uploaded using the 
button. Once uploaded, rename or delete them with the corresponding buttons or audition them by clicking on the file name.
The included "pdm_demo_insert.wav" is for testing and cannot be renamed or deleted.
Uploaded files should be linear (non-compressed) 16-bit stereo or dual-channel mono .wav files. As PDM II cannot change the files' playback volume, please ensure the uploaded files are normalized to match your station's standard.

The maximum supported file size is 6MB. Up to 150MB of audio can be stored in total.
Important: The audio files should be stereo 16-bit WAV files with a 48kHz sample rate to match the sample rate of PDM II's internal clock and ensure proper speed and pitch during playback.
