Audio Files Page

The Audio Files page manages which audio files will be played by PDM II during Insert Build Mode or Overkill Dump Mode.

Files can be uploaded using the 'Choose File" button. Once uploaded, they can be renamed or deleted with the corresponding buttons, or auditioned 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 playback volume of the files, please make sure the uploaded files are normalized to match your station's standards.

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.
