说明： 在c语言的平台上编写语言去噪代码，通过电脑端输入命令可以实现对语言信号的去噪
(The language denoising code is written on the C language platform, and the language signal denoising can be realized by inputting commands on the computer side)

# AudioFile
A simple C++ library for reading and writing audio files.
Current supported formats:
* WAV
* AIFF
Author
------
AudioFile is written and maintained by Adam Stark.

Usage
-----
### Create an AudioFile object:
#include "AudioFile.h"
AudioFile audioFile;
### Load an audio file:
audioFile.load ("/path/to/my/audiofile.wav");
### Get some information about the loaded audio:
int sampleRate = audioFile.getSampleRate();
int bitDepth = audioFile.getBitDepth();
int numSamples = audioFile.getNumSamplesPerChannel();
double lengthInSeconds = audioFile.getLengthInSeconds();
int numChannels = audioFile.getNumChannels();
bool isMono = audioFile.isMono();
bool isStereo = audioFile.isStereo();
// or, just use this quick shortcut to print a summary to the console
audioFile.printSummary();
### Access the samples directly:
int channel = 0;
int numSamples = audioFile.getNumSamplesPerChannel();
for (int i = 0; i < numSamples; i++)
{
double currentSample = audioFile.samples[channel][i];
}
### Replace the AudioFile audio buffer with another
// 1. Create an AudioBuffer
// (BTW, AudioBuffer is just a vector of vectors)
AudioFile::AudioBuffer buffer;
// 2. Set to (e.g.) two channels
buffer.resize (2);
// 3. Set number of samples per channel
buffer[0].resize (100000);
buffer[1].resize (100000);
// 4. do something here to fill the buffer with samples, e.g.
#include // somewhere earler (for M_PI and sinf())
// then...
int numChannels = 2;
int numSamplesPerChannel = 100000;
float sampleRate = 44100.f;
float frequency = 440.f;
for (int i = 0; i < numSamplesPerChannel; i++)
{
float sample = sinf (2. * M_PI * ((float) i / sampleRate) * frequency) ;
for (int channel = 0; channel < numChannels; channel++)
buffer[channel][i] = sample * 0.5;
}
// 5. Put into the AudioFile object
bool ok = audioFile.setAudioBuffer (buffer);
### Resize the audio buffer
// Set both the number of channels and number of samples per channel
audioFile.setAudioBufferSize (numChannels, numSamples);
// Set the number of samples per channel
audioFile.setNumSamplesPerChannel (numSamples);
// Set the number of channels
audioFile.setNumChannels (int numChannels);
### Set bit depth and sample rate
audioFile.setBitDepth (24);
audioFile.setSampleRate (44100);
### Save the audio file to disk
// Wave file (implicit)
audioFile.save ("path/to/desired/audioFile.wav");
// Wave file (explicit)
audioFile.save ("path/to/desired/audioFile.wav", AudioFileFormat::Wave);
// Aiff file
audioFile.save ("path/to/desired/audioFile.aif", AudioFileFormat::Aiff);
A Note On Types
-----------------
AudioFile is a template class and so it can be instantiated using floating point precision:
AudioFile audioFile;
...or double precision:
AudioFile audioFile;
This simply reflects the data type you would like to use to store the underlying audio samples. You can still read or write 8, 16 or 24-bit audio files, regardless of the type that you use (unless your system uses a precision for floats less than your desired bit depth).
