Pd's Audio Settings

First of all, open Pd by double-clicking on the Pure Data executable or app file.

There are two ways to configure Audio in Pd:

• File / Preferences / Audio...

• or Media / Audio Settings...

• ...also (macos only) Pd / Preferences / Audio...

The following window will open:

Make sure that the correct Input and Output devices are selected

Also, take note of the Delay (msec) parameter.

Test Audio and MIDI

This is where we test that our audio is working for Pd.

Go to Media / Test Audio and MIDI...

The following window will open:

Click on "80" to listen to a test-tone playing at 440 Hz.

You can also check your Audio Input levels corresponding to each channel. And you can toggle the Audio Output channels ON or OFF by clicking on the boxes.

Audio Troubleshooting

If there is no sound, then

1. Check the obvious:

   • Sound volumes are UP
   • Headphones are plugged-in, etc.

2. Make sure you've:

   • selected the correct Audio Device in Pd's Audio Settings
   • connected the Audio Device if it is periferal, or
   • set the in/out channels in Pd's Audio Settings to match your device's.

If you hear clicks or pops, then

• In Pd's Audio Settings, set the Delay (msec) parameter higher.

  In general, this should not be above 50 milliseconds.

• (Windows only): make sure MMIO is not selected. Be sure to use ASIO.

  Nowadays most audio interfaces have ASIO, so you don't need to worry about that: just select ASIO and your interface will be connected. However, if you don't have an interface, one solution is to download the latest ASIO4ALL driver (https://www.asio4all.org), install it, re-open Pd, and select ASIO (portaudio) from the Media menu; ASIO4ALL should open afterwards.
