portaudio

I was following the instructions here and I'm having trouble getting the installation to work. Basically, the first part works fine. I downloaded portaudio, followed the instructions, and it all seemed to work. However, when I tried python3 setup.py install , I got an error. The error came from the /src/_portaudiomodule.c file, and it said that "The file Python.h could not be found". I don't really understand what's going on because there was no Python.h file when I extracted the PyAudio archive. I don't know where the Python.h file was supposed to come from. I'm kind of a noob to unix systems

Hi stack overflow users. Error description: For a mini project I have decided to use the portaudio library (I use Windows 7 64-bit and C++): http://portaudio.com/ Before even using the library I had to build a .DLL file in another Visual Studio Project and then link the output to my own visual studio 2010 project (32-bit). I tried to use this simple piece of code: #include <iostream> #include <portaudio.h> using namespace std; void main() { cout << "Hello World!" << endl; cout << "Welcome to C++ Programming" << endl; } I get this error message: fatal error C1083: Cannot open include file:

I'm using speex to encode some audio data and send it over UDP, and decode it on the other side. I ran a few tests with speex, and noticed that if I decode a packet straight after I encoded it, the decoded data is in no way close to the original data. Most of the bytes at the start of the buffer are 0. So when I decode the audio sent over UDP, all I get is noise. This is how I am encoding the audio: bool AudioEncoder::encode( float *raw, char *encoded_bits ) { for ( size_t i = 0; i < 256; i++ ) this->_rfdata[i] = raw[i]; speex_bits_reset(&this->_bits); speex_encode(this->_state, this->_rfdata,

I'd like to tell you what I've tried and then I'd really welcome any comments you can provide on how I can get PortAudio and PyAudio setup correctly! I've tried installing the stable and svn releases of PortAudio from their website for my Core 2 Duo MacBook Pro running Snow Leopard. The stable release has a sizeof error that can be fixed(?) , but the daily svn release installs fine with ./configure && make && make install (so this is what I'm using). The tests are compiled properly and I can get the binaries to produce output/can read microphone input. Ok, so then PyAudio has troubles.

I am trying to generate a tone to the sound card (Frequency: 1950 hz, duration: 40 ms, level: -30 db, right-channel (stereo), on steam 1). Eventually, I would like to play two of these tones (one goes to channel 1 and one goes to channel 2). Any help or direction is greatly appreciated. Thanks, DW Hi Bjorn, I tried this but I am not getting the what I am expecting as a frequency (plus seems sound is not clean). Any ideas what's wrong? I greatly appreciate any help. #define SAMPLE_RATE (44100) #define TABLE_SIZE (200) float FREQUENCY = 422; ... for(int i=0; i<TABLE_SIZE; i++ ) { data.sine[i] =

As in this example How to extract frequency information from an input audio stream (using PortAudio)? I'm curious about portaudio and numpy... I'm not 100% sure about fft, how can I pass numpy a chunk and get back three values from -1.0 to 1.0 for bass, mid and treble ? I don't mind if this just for one channel as I can make sense of the audio part of this, it's the maths that swim in front of me when I look at them :) Actually, you would not use a Fourier transform to do this. Splitting any audio signal in bass, mid and treble is usually done using filters. A filter is a signal processing
