* * Pd procedure report * *

1 - In order to be able to detect motion in Pd by using a video input, we need to use "gem" library.

2- "Pd vainilla" doesn't install "Gem" by default. We need to download it and drag the folder in Users>Library>Pd (if there is none, we create one)

3- Specify the "path" to this folder on Pd preferences.

4- Oops, the webcam is still not detected! :@

5- Apparently, Gem doesn't work with newer versions of Mac OS in "Pd Vainilla"

6- Let's try downloading "Pd - Extended", checking the path, etc.

7- Now it works! webcam is detected in Pd, success.

8- However, the log sends me errors of files that couldn't be loaded. Weird.

9- I keep on experimenting with the patch also using different tools from the gem library; pix_color/grey and other filters, rectangle shapes and positioning, pix_blob 4 using Osc to create sounds out of motion detection, etc.

10- I try to import audio to "Pd-extended" using different methods: "openpanel" by uploading everytime the audio file and "open" from path. ...but Pd cannot open the audio file! :@

11 - I need to Download XQuarz so my system's library will be automatically updated.

12- Now we can import and listen to audio files! :)

13- Another Issue; the audio file plays far too fast

14- Check out that the sample rate of the audio file corresponds to default Pd audio settings:
- in preview: (e.g. 16 bits per sample)
- in Audacity: Sample Rate e.g. Format (32-bit float)
- Default setting in Pd: e.g. Sample Rate: 41000

15- Audio sounds correct.
