Hello, with this patch I want to record in a buffer, and when it finishes, it must play the recorded sound reversed. It does it, but there are two clicks always, when it starts and at the end. Any idea why it happens?

Setup: MB Pro, RME Fireface400 and Max/MSP 5.1.8

Seems like a ton of objects there. Here's a lower object count version on the right. I'm not hearing much in terms of click but you can use the trapezoid~ trick on the output of groove~ driving a *~ to remove any clicks at the start/end.

Also if you want it to time out use an audio rate sync (out of record~) as you will likely run into problems mixing [delay 4000] with [record~ 4000] as the two timing systems aren't locked together.

yep, it is the delay object. you must always try to convert data into signals at only one point.

also, i would use tapout~ and not buffer~ for that effect.

Ouch, how easy it was to reverse the sound... thank you very much.

But how I do if I want to play exactly when the recording has finished? Because I was using delay to play it just in that moment, but now I don´t know how I can do it.

Roman, how would you use tapout~? I can´t imagine...

Ouch, how easy it was to reverse the sound... thank you very much. 

This will start playing as soon as you finish recording.

Thank you very much, I learned a lot of things that I didn´t know with your patch :-)

Why do I have "clicks"?
