# 03-read-from-ram.py - Soundfile playback from RAM.

Reading a sound file from the RAM gives the advantage of a very fast access to every loaded samples. This is very useful for a lot of processes, such as granulation, looping, creating envelopes and waveforms and many others.

The simplest way of loading a sound in RAM is to use the SndTable object. This example loads a sound file and reads it in loop. We will see some more evolved processes later…

    from pyo import *

    s = Server().boot()

    path = SNDS_PATH + "/transparent.aif"

    # Loads the sound file in RAM. Beginning and ending points
    # can be controlled with "start" and "stop" arguments.
    t = SndTable(path)

    # Gets the frequency relative to the table length.
    freq = t.getRate()

    # Simple stereo looping playback (right channel is 180 degrees out-of-phase).
    osc = Osc(table=t, freq=freq, phase=[0, 0.5], mul=0.4).out()

    s.gui(locals())
