Hello, I've got a few codes that use "arrayrange" within numpy. It happens that the new version of numpy apparently doesn't recognize "arrayrange"... I've tried to change it to "arange", but it doesn't work... So, for example, the code below used to create a sine wave file, but it's not working anymore... Does anyone have any clue of what may be a solution for this? Thanks!!! Miguel # Basic sound generation # Generate a sine wave and stick it in an AIFC file # Assumes mono, 16-bit sound # SRate, duration, and frequency are variables from numpy import arange, sin, pi from array import array import aifc print "----------------" SRate = 44100.0 # sampling rate of the output file durSecs = 1.0 #its duration in seconds durSamps = int(SRate * durSecs) # resulting number of samples freq = 330 #frequency of the sine wave in Hz (cycles per second) maxShort = 2** 15 # the largest possible signed 16-bit integer # Make a floating point sinewave array using two handy functions from NumPy: t = arange(0, durSecs, 1.0/SRate) sineWave = sin(2*pi*freq*t) # print "max value of sine is: " + str( max(sineWave)) # Now write it into a 16-bit integer array, adjusting the values to "fill" that format sineWaveArray = array('h', [0]*len(sineWave)) for i in range(0, len(sineWave)): sineWaveArray[i] = int(sineWave[i] * maxShort) # Finally, write it to an AIFF file filename = str(freq) + ".aiff" out = aifc.open(filename, "wb") out.aiff() #out.setparams((1, 2, 44100, 100, 'NONE', 'not compressed')) out.setparams((1, 2, int(SRate), int(durSamps), 'NONE', 'not compressed')) out.writeframes(sineWaveArray.tostring()) # this is the crucial step: the .tostring() method forces this into the string format that AIFC requires out.close() print "Successfully wrote a sine wave of frequency " + str(freq) + " to file: " + filename
