liveRecord
live samplerecorder to be used with the livePlayer. Uses a 32bit "starts" table and a 16bit "samples" table. Autoclear resets the entire buffer when the recorder goes over the maximum time.
Inlets
frac32buffer wave input
bool32 when high, records input into the table at next start position
bool32 when high, clears buffer and start positions
Outlets
None
Parameters
bool32.tgl autoclear
Attributes
objref this should refer to a 16bit table allocator (sdram)
