Returns the amplitude equivalent for a given decibel amount. This opcode is the same as db.
Here is an example of the db opcode. It uses the files db.orc and db.sco.
Example 90. Example of the db opcode.
/* db.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 ; Calculate the amplitude of 40 decibels. idecibels = 40 iamp = db(idecibels) print iamp endin /* db.orc */
/* db.sco */ ; Play Instrument #1 for one second. i 1 0 1 e /* db.sco */
Its output should include lines like:
instr 1: iamp = 100.000
