tabread

Table lookup with linear interpolation

tabread has the following arguments:

• index: index position
• scaled: 0 or 1 indicating whether or not to scale the signal. A value of 1 expects the index to be in the range 0-1. A value of 0 will make the expected input signal to be the actual index number
• wrap: using wrapping. Can be used to make hard-sync oscillators
• offset: initial phase offset
• ftname: name of the table

The following patch below shows how tabread can be used to make a table lookup oscillator.

 # Generate sine wave lookup-table
 _sine 8192 gen_sine
 # create 440hz phasor signal (sawtooth moving between 0 and 1)
 440 0 phasor
 # feed phasor into tabread 
 1 0 0 _sine tabread 
 # scale signal
