Howdy all.

Im working on something at the moment and I think PD is the solve to my problem.
Im designing sounds for electric cars. Im doing that part in Logic, im more efficient there. I wanna make a dozen or so engine sounds and put them in a soundscape.

To bring them to life I will need to control the pitch and speed to be able to 'drive' them. Some panning and fake doppler effects and I should be able to create an artificial future street.

create a sound in Logic- bring it into PD- 'perform' it- export it as a wav- import that to Logic and arrange.

So my Pd shopping list is ;

Soundfiler~ - to import a .wav.
soundtouch~ to control pitch (dunno if this is the write one)
recfiler~ (forget the proper name of this one)

A pitch and speed controller.

Any advice would be much appreciated on this as my Pd skills are limited!!

Thanks for reading.

If you're just looking to get the job done rather than learn the ins and outs of PD, then you should consider finding a pre-made sample player and adapting it to suit your needs. There are several examples in the help files: Help Browser --> 3. audio examples --> B09 to B14.

You should also check out Johannes Kreidler's tutorial, which will walk you through most of what you need to know and has more examples: http://pd-tutorial.com/english/ch03s04.html

PS. I don't think that there's an object called [soundtouch~], but pitch control can be achieved just by speeding up and slowing down the [phasor~] or [line~] that you're using to control the sample playback. By "recfiler~" you probably mean [writesf~].

thanks man. Im a bit on the fence really. I wanna learn the ins and out of Pd. I did a module in it last year. Im just real realy slow on Pd, so those premades might just do the trick. I just need to combine them all (wav in, speed and pitch control, record and export wav.)

I may be back with a mock up soon.

They aren't what I had in my mind really. I'm using readsf~ to read a .wav file. Once thats playing back I wanna make a slider that can control both speed AND pitch. I'm working on that at the moment.

How can I record that performance?

Also readsf~ keeps giving me 'no such file or directory' even though the file exists and playsback. Ive even put the audio file in the same folder as the pd patch.

Pd is also running REALLY slugishly which doesnt help. Everything else is working as normal. Weird.

David.@delphineTA Hello Delphine.....
[readsf~] just plays a file from disk, as any old player (like quicktime) would do. It doesn't give you any options for speed or pitch.
You need to bring it in to the ram on your computer so as to play around with it so you should use [tabread~] or something similar. But there is a limit of 40 million bits for the file (about 907 seconds of mono 44.1kHz 16bit).
If everything is sluggish then your audio settings for Pd are probably wrong.....
This will do what you want (it plays your file..... replace the one in the folder with yours but give it the same name) over and over again and you can change the speed/pitch and record the output.... it is actually B10 from the examples @Liam suggested, and I have modded it a bit.......
delphine engine patch.zip
(You might also have to play around with the chunk size if your file is long... the one I have included is only about a second..... that is all it needs).
David.

Yea that's the one alright (every time you somehow hit the nail square on the head) Im having a bit of trouble recording my 'driving' of the car to a .wav. ALWAYS had trouble with that part though so nothing new there!!

@delphineTA Hello Delphine........ are you having trouble with the "recording" bit that I put in the middle of the patch......... can you give me any clues about "why" if that is not working...... it should just dump a recording called (bizarrely-- haha/hehe!) recorded.wav in the same folder.
I had assumed that "mono" would do. It should write a file continuously (so........ as long as you want) between when you press the "start" bang and the "stop" bang just below the comment "RECORDING"........ you can chop it to the length you want and adjust volume etc. afterwards in Logic........

This is why I love Pd. Before my dinner all was well apart from the record bit. Your recorded.wav was just empty but for the right amount of time. So i WENT FOR DINNER.

i come back re-open it and now I cant even load a file!!! Now it just says no method for 'filename'. I am coying directly from the file not re-writing it.
So I deleted the whole folder, samples and all and re-downloaded it frash. Your voice.wav auto loads fine.. In fact Ive been listening to it on and off for an hour now

And in the process of writing this I've had another go at the patch AND THE RECORD FUNCTION NOW WORKS REALLY WELL!!!!

Now I just need to fix the load a sound thingy.

Thought it may have been a sample rate. Mine was at 96 kHz. Opened it in quicktime and exported it to 41 kHz. Still same thing happening.
For now I conceed to pd.
You win this time!

@delphineTA Yes, unfortunately it's a computer....... even little mistakes bite you! It is clueless....... And they reckon AI is just around the corner???

Totally agree, computers are great and all but its one hell of a long corner until we see Ai !
