glitches when scrubbing audio


    Oct 27 2008 | 1:17 pm
    Hi, Is there a way to get rid of audio clicks/glitches when I scrub in an audio file?
    I am talking about artefacts when I CHANGE the loop's start and/or end. Once the loop is set there is no glitche, grooveduck~ does its job and the loop is perfect.
    I seems that I got more glitches when I move start point from left to right.
    I tried to send start point value thru a [sig~] but it didn't help.
    here is a small patch to illustrate:
    thanks a lot for your help

      Besides finding/using zero crossings in the loop audio you could as well highpass filter the incoming audio before looping with an [svf~ 100] and a second [svf~20] after loop audio output.

      Hi Jayrope,
      Sorry but I don't get it.
      could you tell me more or post an example please ?
      thx a lot olivier

      Here's a thread on the same topic:
      And here is the fe.nocut~ abstraction mentioned in the thread which always works for me. It ducks the amplitude of a signal in its signal inlet when a message (in this case the start or end point) is passed through its message inlet:

      Would you post this as a 4.6 compatible text version, too?
      Thank you very much!

      hello Lewis,
      thanks for the link
      Actually I read it a few days ago but I didn't choose the solutions given there because they cause some pitch artefacts when you change loop lenght :( But I overlooked the solution from fe.
      thanks to you and him I can achieve what I need now.
      here is a patch where 2 grooveducks with and without fe.nocut~ are used.
      BTW,now I am trying to get rid of the granular effect caused by amplitude modulation, it is a never ending story I guess ;-)
