processing an audio wav file with C - Stack Overflow
https://stackoverflow.com/questions/2457482/processing-an-audio-wav-file-with-c
Another option is to remove your audio processing logic and simply read in the source file to your internal buffer and write it out to a file. If your code can generate a valid, working output file in this manner, then you can narrow down the problem to your processing code. You may also want to start with a smaller file than 40Mb.

The following C++ code example shows an implementation of the APOProcess method for the sample class that you created in step 1. For an actual implementation of this concept, follow instructions in the Audio Processing Objects Driver Sample section to go to the Swap sample, and then refer to the Swapapolfx.cpp file.

Learning to work with audio in C++ - Stack Overflow
https://stackoverflow.com/questions/711350/learning-to-work-with-audio-in-c
C++ can be a great language to do audio processing in, I use the Marsyas framework, a cross-platform package that lets you do complicated tasks in audio signal processing, music information retrieval and machine learning really easily. It's also really fast, and you can do lots of complicated tasks in real time, unlike many other packages.
C Programming for Sound Processing

You should understand that sound in computers is encoded as pcm (pulse-code modulation) data. A .wav file is just straight pcm data with a header on it; compressed formats like .mp3 take pcm data and encrypt/compress it.

Copy-paste C++ audio code between Android, iOS, macOS, tvOS, Linux and Windows. 2. Low Latency, Real-time Audio Processing. Audio processing is a real-time process in which developers have to perform complex DSP transformations in a few milliseconds to queue up the audio stream in the buffer.
Any OpenCV-like C/C++ library for Audio processing ...
https://stackoverflow.com/questions/6938634/any-opencv-like-c-c-library-for-audio-processing
For audio capture and playback, portaudio comes to my mind. For audio processing, STK looks promising. Have a look at this related question too: Can anyone recommend a decent DSP/speech library in C++? I recommend these three libs: very easy to use and friendly for general signal processing Aquila-dsp

Audio Processing Code Write in C or C++. Avoid assembly. Use block processing Optimize only as much as is necessary As little assembly as possible. Separate assembly code into a set of optimized processing functions Segregate audio processing and framework code Audio processing is reusable Framework code is target specific

https://github.com/cycfi/Q
Audio DSP Library. Introduction. Q is a cross-platform C++ library for Audio Digital Signal Processing. Aptly named after the "Q factor", a dimensionless parameter that describes the quality of a resonant circuit, the Q DSP Library is designed to be simple and elegant, as the simplicity of its name suggests, and efficient enough to run on small microcontrollers.
