Segment duration

I’m currently exploring MuBu, playing around with the help and tutorial patchers, e.g. onseg-with-fft-sum in MuBu-howto-segmentation. It seems that I’m blind because I didn’t find a way to change the maximum duration of segments of 1 s in playback with mubu.concat~. I tried out setting @period to 0 3, adding @duration 12000 and @maxduration 12000, the longest segment duration played is always 1 s, although the longest duration in the segments track is by far longer than this. What must one do to get longer durations?

Is the maximum duration of segments played back by mubu.concat~ 1 second?

Hi Kyl, it is what you give as @maxduration (default 5000 ms). If it doesn’t work for you, can you post an example patch that shows the problem?

Hallo Diemo, thank you for your reply.

I’m just playing around with the tutorial patch MuBu-Overview/tutorials/MuBu-howto-segmentation/onseg-with-fft-sum. For example, when I load a sound file from my archives and apply an onseg.threshold of 25 to the {{mubu.process […] onseg […]}}, I get the following dump from a mubu.track fftsumseg seg (which I added to examine the content of the track):

data: 5.333333 6517.333496
data: 30848. 7994.666504
data: 38842.667969 3541.333252
data: 42384. 3189.333252
data: 45573.332031 906.666687
data: 46480. 4848.
data: 51328. 22229.333984
data: 75504. 2704.
data: 78208. 17850.666016
data: 96058.664062 3104.
data: 99162.664062 3797.333252
data: 102960. 933.333313

Thus, almost all segments are longer than 1000 ms. However, when I trigger segments with the cursor in the imubu, {{mubu.concat~}} only plays the first second (repeating it until I displace the cursor). Increasing {{@duration}} or {{@maxduration}} or other attributes I tried out didn’t accomplish to overcome the 1 second limit. So my (maybe kind of stupid) question is: How does one increase the maximum playback duration per segment?

(Don’t be confused by the double curly brackets. I lapsed into another Wiki syntax for code style, sorry. Just read code in place of {{…)

Cheers, Kai Yves Linden
