each segment also stores it's average energy (root-mean square): each segment is also offset slightly (sub-sample phase delay): the length of each segment (in samples): the segment storage (each segment on its own channel):

When the segment playback is done (possibly after several repeats),Ī new segment is selected according to the current strategy (play_mode) To ensure the sub-sample phase offset is used and retained between segments Playback includes additional calculations, The playback section is continuously playing a segment (play_segment) When a segment finishes recording, a new segment is chosen to write into (write_segment) The segment_data recorded includes the sample just before the first crossing,Īnd the sample just after the last, in order to contain both actual crossings. It also stores the sub-sample accurate segment length (in length_data) The program estimates this sub-sample crossing phase (and stores it in offset_data) The actual crossing is somewhere between a and b. Since waveforms rarely cross zero at an exact sample location, Instead the input is segmented at points where the signal is rising and crosses zeroįor pure sounds a segment corresponds to one or more wavecycles,īut for complex sounds it can be somewhat stochastic. Which selects and plays these grains one-by-one Which stores grains into a Data object (segment_data) The program contains a recording section, It could be seen as a time-domain, granular form of analysis/resynthesis. This program divides the input into segments, and plays these segments back. If you have any questions or want me to post some additional media I will gladly do so, this would be a RAD teensy object that I am currently trying my best to grow the skill to create, but I am sure someone with more experience would be able to do it cleaner/faster.

If you have puredata, or are willing to download it, I can upload one of my patches with comments showing my favorite grain styles.įor now here is a link to a nice pure data tutorial on how to build a basic phase ramp driven grain method to get some ideas: This approach is more smooth and allows for extremely clean time scrubbing when there are 4-6 grains evenly spaced along the phase ramp. I had started to attempt this with what is already available using the queue into a larger buffer that a few wavetables play back through, but 256 is not quite enough samples.

Which would be an easy modification/merger of the wavetable oscillator object and file playback objects.

Or use a phase accumulator to drive through the windows and evenly spaced grains Parameters for grain length, number of grains, either trigger the grains to play at random times for a very 'grainy' grainular (I believe you have a hanning array in the FFT already? those work great)įrom there you have the option to add randomness into the buffer read position offset of each grain. I am trying to think of the best way to structure a flexible granular object for this:Īt the core, a grain is a small section of an audio file through a window I might be able to help a bit on the Teensy coding side, but for this to come together well anytime soon, it really depends on you guys for the knowledge and experience and testing of the granular synthesis side. But the request keeps coming up to support this in the audio library. I don't have much (well, really any) experience with granular synthesis.
