[Tutor] How to generate a pure tones and random noise using Python?
Hi All, I try to train my listening by using python. (estimating the frequency of sound) So... Are there some way to generate a fixed frequency sound in different waves (eg. Sine Wave, Saw Wave, Triangle Wave etc.) and different random noise. (eg. white noise & pink noise) ? I have search in web, some people say that I can use winsound which can generate a fixed frequency beep. However, It is Windows only. (I'm under Linux) and I think It is not a professional library to generate audio signal. How about pygame? and some examples? any ideas?

Re: [Tutor] How to generate a pure tones and random noise using Python?
Hi Laura, Thanks for you helpful reply, and it is exactly what I want. I'm going to learn Python from write a ears training program. ;-) And Is there have a library to scope(print) this wave form? (real-time and non real-time) I have already started to learn "generate audio with python", Thank you. :-) Paul Z > To: p...@whoosh.cn > CC: tutor@python.org; l...@openend.se > From: l...@openend.se > Subject: Re: [Tutor] How to generate a pure tones and random noise using > Python? > Date: Sat, 25 Jul 2015 22:35:24 +0200 > > In a message of Sat, 25 Jul 2015 19:15:31 +0800, Paul Z writes: >>Hi All, >> >>I try to train my listening by using python.

Re: [Tutor] How to generate a pure tones and random noise using Python?
Hi Laura,
I just have read this webpage about Generate Audio with Python.
It seem writing by Python 2? Esp. itertools (izip, imap).
I try to change izip and imap to zip and map, but I get error:
beatfreq, amplitude = remainder.split('/')
ValueError: need more than 1 value to unpack
Are there some way to conver it to the code of Python 3?
I'm too anxious to hear the sound from Python though I'm a absolute beginner.
Many thanks
Paul Z

[Tutor] a beginning question
Hi all, I receive the string messages from my Mobile via UDP as below: A, 0.1, 0.6, 0.7 B, 0.2, 0.3, 0.8 I want to arrange them to two array as below: a = (0.1, 0.6, 0.7) b = (0.2, 0.3, 0.8) all the number are float.

Re: [Tutor] a beginning question
Hi,
I writed some codes as the UDP messages:
import socket
import random
from array import *
port = 8088
host = "localhost"
s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
num = array('f')
x = 0
while x < 6:
num.append(random.random())
x += 1
a0 = str("%.2f"%num[0]) + ','
a1 = str("%.2f"%num[1]) + ','
a2 = str("%.2f"%num[2]) + ','
a3 = str("%.2f"%num[3]) + ','
a4 = str("%.2f"%num[4]) + ','
a5 = str("%.2f"%num[5]) + ','
msg1 = 'a,' + a0 + a1 + a2
msg1 = bytes(msg1, 'utf-8')
msg2 = 'b,' + a3 + a4 + a5
msg2 = bytes(msg2, 'utf-8')
s.sendto(msg1, (host, port))
s.sendto(msg2, (host, port))
and I receive the messages via:
import socket
port = 8088
s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
s.bind(("",port))
print('waiting on port:',port)
while True:
data,addr = s.recvfrom(1024)
print('reciveed:', data, "from", addr)
I want to arrange the messages to:
array1 = #the numbers which is start as 'a' in the messages
array2 = #the numbers which is start as b in the messages
Thanks!

[Tutor] how to receive messages form a server?
Hi, There is AP with UDP-Server(sending UDP messages). My computer has connected the AP. I know how to receive messages form a client via socket. But, Now, how to receive messages from a server?
