Functions

adsr

def adsr(
    length,
    attack,
    decay,
    sustain,
    release
)

fromfile

def fromfile(
    filename,

polyseg

def polyseg(
    segments,
    length
)

Calculate total output segment length in frames & alloc outbuf

loop thru segments: - generate segment - write segment into outbuf

for each segment: - calc the true length of the individual segment based on segment length - scale the size of the tmp segment to match remainder after start/end filtering - produce a tmp array from the waveform type (using normal wavetable or window generator) - copy into outbuf

segment crossfading?
