Hi list,

I'm still tinkering around with Csound on an iPhone 4. There, I have the following scenario:
25 Samples get buffered into ftables and may be started by user request. The samples are then played back via flooper. This is running quite well but every time a sample gets started there is an audible click (audio dropout) now i wonder if this performance issue may be resolved on this hardware inside Csound by using other opcodes or a different strategy for playing the samples. I thought if the samples are preloaded into an ftable there should be no big computational overhead when starting their playback.

Best,
Martin

Do you have an amplitude envelope in your instrument? If the click is at the start of the sound, the reason might be just the lack of one.

Also, have you tested this on Desktop and are there clicks there?  If
so that may give us some clues on how to optimize.

Hi Victor,

sorry, forgot to mention that there is an amplitude envelope on the sample players. I think its an performance issue.

Best,
Martin

Hi Steven,

On the desktop there are no clicks. There are plans to test the patch on other iPhone-versions, too. But I thought maybe there's a software solution around this problem.

Best,
Martin

Could you share the CSD here for us to take a look?

Here you are:



I think, everything is pretty much straight forward. The score contains at the end some instructions, that would normally be generated by the GUI on the phone and send to Csound by sendScore instructions.

I see you are using diskgrain. That one reads from disk, better to use syncgrain reading from a table instead.
Also, is there any reason not to write a single table for all instances to use?
I'm thinking here of

gihann ftgentmp 1, 0, 8192, 20, 2, 1

which could just be

gihann ftgen 1, 0, 8192, 20, 2, 1

in the header, instead of being into an instrument. Similarly, other uses of ftgentmp might be changed.

I can't see the use of flooper anywhere.

Victor

sorry this was the the wrong file! :-( sorry for that! here is the right one:



Most of the ideas you mentioned i realized already, as you can see in the actual version.

Try replacing flooper by flooper2. Flooper copies the tables into its own memory space, that might be the problem.

Thank you, Victor!

Hi Victor,

flooper2 works fine but it has one dawback: It won't accept negative pitches. Is there some possibility to have the memory management of flooper2 with the functionality of flooper? I'd like to do scratch-effects, so an if statement to distinguish between forward and backward running samples is no option... Would it be necessary to build an opcode to achieve this? 

Best,
Martin

I guess flooper2 was not designed for that. Did you try syncgrain or syncloop?

maybe you can use this UDO ...
http://www.csounds.com/udo/displayOpcode.php?opcode_id=83 (mono)
http://www.csounds.com/udo/displayOpcode.php?opcode_id=84 (stereo)
... or even build a simplified version if this is too complicated?

one of my students worked with it and the performance was fine.

I'll try both options, the syncloop and the UDO
