- Hello! I am using SGI Indigo to analyse
- various sound. I know AIFF is a standard
- file format for an audio file.
-
- From the standard audio file, how can I
- get the amplitude of the sound within?
-
- After decoding, one should have a sequence
- of integers or floating points(I am not sure)
- which represent the amplitudes of the sound
- wave in a period of time. If the sampling
- rate is 44.1KHz, that means there are 44,100
- integers or floating points.
-
- How can I get these numbers? Anyone knows
- the answer? Thanks!
