GRAINS - a granular processing patch
HOW TO USE:
- Open "grains.pd."
The application will initialize with "ms1.wav", one of the provided audio files, as the input file. You can import your own WAV files by placing them in the "audio" folder and typing their name into the "filename" symbol box.
- Change parameters
Click and drag on the number boxes, or click and type numbers, to change the parameters.
Parameters include:
-
grain_dur: the duration of each sound grain, in samples.
-
samples_between: the duration of silence between grains, in samples.
-
percent_sample: the percentage of the sample that is to be played, starting from the beginning.
-
pitch: pitch adjustment. 1 is no change. 0.5 is 2x faster, 2 is 2x slower, etc.
-
offsets: these parameters create discrepancies between the parameters being passed in and the ones that affect the actual output. Honestly even I don't understand exactly what they're doing. Just adding numbers to other numbers to achieve an interesting result.
- Record output
Type the desired output filename into the output_filename symbol box and click on the "rec" toggle box. Click on it again when finished.
