Hi

I'm using Granular Synthesis in an audio patch, Currently the patch isn't working but i know if i tweak it a bit it will. (if anyone has used this technique, please respond! Its basically just a combination of using tabread4~ and samphold~)

So its mainly not working cos you have to know the number of samples in the audio file and i don't know how i calculate that. My file is 4 mins 38.32 secs long., 16 bit, stereo, 44100Hz (wav)

Anyone know how to do this? also if anyone has a successfully working patch, please share!

@musicproject Here you go......... the top one is a different size because its not your file.......
size.pd
David.

that just gives me the file size, the number of samples is different. I know the 1.22739e+007 figure already, but thats not the number of samples. Thanks anyway

@musicproject You are right in that the calcs are accurate to the nearest 100 samples...... The top one because of the display limitations of Pd in 32bit and the bottom one because you don't know the exact length of the track.........
Your wav files are uncompressed........ but its still not possible without knowing the exact length.
You said you have adobe audition......... "File" ... "File Info".... at the bottom........
The [soundfiler] object does output the correct number. If you open the properties of the array and open list view and click down forever it will show you the sample number and value.
In audition it is easier......... zoom into the last sample and right-click its little "square" for the same information............

@whale-av what i posted is all the 'File Info' it doesn't calculate the number of samples for you. Adobe is actually pretty basic. Audacity is worse.

@musiproject Actually audacity does the job. If you don't need to calculate everytime you open a file in PD and you can do it beforehand.
Just open or drag and drop your file on audacity. Then at the bottom you can choose to display time or samples. You can also place the cursor anywhere or select a given amount of samples. Then you get the starting sample and the amount of samples selected. I use this often when I want to play just a portion of a file using [tabplay~].

Good luck.

@musicproject Maybe you don't have Audition3 or the new cloud version is more basic.........
The first sample (its your original 48k file) is "0" and the last "13361369" so "13361370" total samples as reported by "file info" and by [soundfiler]........ the output of [soundfiler] can be used in your patch.......... it does not show the last digit in the number box....... but it is sent to the next object.......
