sampler offset option

  Hi Jan-Bernard,

  What do you mean exactly with an offset? Do you mean that you want to start playback only after a certain delay? If so, then you might want to look at coroutines which allow you to specify timing in a more flexible (and less sequential) way than sequence items:

  Or is that not what you mean?

  Hi Sebastiaan,

  Sorry, that is not what we want. With offset, we mean : start playing the track at a certain moment of the track (start at 1:01 for instance...)

  Thanks, JB

  Hi JB,

  Ah, I see. No, the pygame mixer doesn't allow you to seek through the stream. There's a few options.

  • The easy option is of course to create separate audio files, each with a different offset. If you require only a few offsets, that's what I would do.
  • Use the wave module to open the audio files (in .wav format), and write only the part from a certain moment onward to a new wave file, which you then use in the sampler.
  • Use a more advanced library such as pyaudio that does allow you to seek through files.

  Cheers!
  Sebastiaan
