de.sciss.eisenkraut.io.DecimatedWaveTrail.readFrame()

Reads a block of subsampled frames. @param info the DecimationInfo as returned by getBestSubsample, describing the span to read and which resolution to choose. @param frames to buffer to fill, where frames[0][] corresponds to the first channel etc. and the buffer length must be at least off + info.sublength! @param off offset in frames, such that the first frame will be placed in frames[ch][off] @throws IOException if a read error occurs @see #getBestSubsample(Span,int) @see DecimationInfo#sublength
