问题 I am using Code::Blocks to test some codes, and I just can't biuld this code: #include <stdio.h> #include <stdlib.h> #include <sndfile.h> int main() { SNDFILE *sf; sf = sf_open("file.wav",SFM_READ,&info); //error happens in this line ... And the error is "undefined reference to `sf_open'", this not only happens to sf_open but also to any function from sndfile.h. Actually here is what I did to get here: I've first downloaded and installed libsndfile for Windows x64 (I'm using Windows 10) from

问题 I am teaching myself how to read in wav files into C++ as a part of me learning C++. I have found many resources online that recommended the following library: libsnfile library So I followed some tutorials below in testing the basic functionality of the library, but I can't get the library to compile with Visual Studio 2010. I have searched online for the following error, but did not find anything useful for my particular error. I downloaded the libsndfile C++ windows installer found here. I

问题 I just completed a proof of concept, or so I thought, of feeding Microsoft Visual Studio 2010 some C++ code as a console program. The C++ code that compiled is given below: #include "stdafx.h" #include <stdio.h> #include <Windows.h> #include <stdlib.h> #include <sndfile.h> //The following libraries are related to parsing the text files #include <iostream> //Open the file #include <fstream> //Reading to and from files //The following libraries are for conducting the DTW analysis #include "dtw

WAV-file analysis C (libsndfile, fftw3)

阅读更多关于 WAV-file analysis C (libsndfile, fftw3)

问题 I'm trying to develop a simple C application that can give a value from 0-100 at a certain frequency range at a given timestamp in a WAV-file. Example: I have frequency range of 44.1kHz (typical MP3 file) and I want to split that range into n amount of ranges (starting from 0). I then need to get the amplitude of each range, being from 0 to 100. What I've managed so far: Using libsndfile I'm now able to read the data of a WAV-file. infile = sf_open(argv [1], SFM_READ, &sfinfo); float samples

问题 When updating to R 3.2.0 I had to reinstall seewave . I managed to install the required packages fftw , tuneR , rgl , and rpanel . But, when trying to compile seewave I got the message: stft.c:3:11: fatal error: 'sndfile.h' file not found 回答1: On linux it is sufficient to install libsndfile library, for example with sudo apt-get install libsndfile1-dev On OS X just do: brew install libsndfile 回答2: Pisca46 - Installing via 'brew install libsndfile' helped. 回答3: On CentOS, the package has a
