lrec
records audio to a table.after recording is done,the length of the recording in samples is sent out, as well as the length of the recording (in fraction of the table's size)
Inlets
bool32.risingfalling record
frac32buffer audio in
Outlets
frac32.positive length of recording in fraction of the table
int32 length in samples
