PureData

Installation & Setup

“Microsoft Defender SmartScreen blocked an unrecognized app from starting. Running this app might put your PC at risk.”

This is because PureData isn’t from a “recognized publisher,” and open-source software often triggers this kind of warning.

How to Bypass SmartScreen Safely:

1. On the warning dialog, click "More info".

2. Then you should see a "Run anyway" button—click that.

3. Follow the installer as usual.

PureData's default font can be tiny, especially on high-res screens.

How to set the font bigger:

Edit > Font > font size

File>Preferences>Edit Preferences

1. Use Speaker channel, earphones are not recommended.

2.Keep things in default is easier, changing the "delay"etc might cause error.

DSP is "the engine that processes audio"

When DSP is on, Pd starts computing everything connected by audio signals (the thick lines between `~` objects).

- DAC: In Pd, creating sound with objects like `[osc~ 440]` (a 440Hz sine wave) doesn't mean you'll hear anything until you connect it to `[dac~]`.

- "*~ ":Most commonly, you use this to **control volume** (aka *amplitude*).

- There has to be a space between "~" and the number it leads to

- Filter: lop/hip/bp(Q factor)

- line: receive message and output a ramp (slope)
