sampler offset option

marsman

Dear experts,

Is there a way to provide an offset to the sampler object, using inline code?

Many thanks in advance,

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:

• http://osdoc.cogsci.nl/3.2/manual/structure/coroutines/

Or is that not what you mean?

Cheers,

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!
