Description
Examples
Get Signal
Load a labeled signal set containing recordings of whale songs.
load whales
lss
lss = labeledSignalSet with properties: Source: {2x1 cell} NumMembers: 2 TimeInformation: "sampleRate" SampleRate: 4000 Labels: [2x3 table] Description: "Characterize wave song regions" Use labelDefinitionsHierarchy to see a list of labels and sublabels. Use setLabelValue to add data to the set.
Retrieve the second member of the set and plot it.
[song,tinfo] = getSignal(lss,2); t = (0:length(song)-1)/tinfo.SampleRate; plot(t,song)
