Libavcodec tutorial: decode virtually any audio file in C ...
https://rodic.fr/blog/libavcodec-tutorial-decode-audio-file/
After hours browsing the Internet, I couldn’t get my hands on a working tutorial to simply extract audio samples from a file using libavcodec. So here’s to you, a full working example! Warning. FFMPEG and the libraries it depends on are often updated, and their API can drastically change between versions. This code works with the libraries ...

libav: Visualize audio in a spectrum using libavcodec. Jun 18, 2015 · 5 minutes read. ... The last useful bin (for practical aplications) is at N / 2 - 1, which corresponds to 22006.9 Hz in the above example. The bin at N / 2 represents energy at the Nyquist frequency, i.e. Fs / 2 ( = 22050 Hz in this example), but this is in general not of ...

libavcodec and libavformat are pretty awesome when it comes to decoding/demuxing audio streams. They provide a codec and format agnostic API that processes containers, extracts metadata, and and decodes streams as fixed-size packets one by one into PCM samples. Unfortunately, libav is not very easy on beginners. It's very difficult to find code …

I had the same problems. It seems libav mp2 decoding by default outputs in S16P format (planar) which is not so common in various audio editing applications that support raw input (audacity for example). I solved my problem by specifiying request_sample_fmt in AVCodecContext being AV_SAMPLE_FMT_S16.
14.3. Encoding with the libavcodec codec family
https://www.cs.ait.ac.th/~on/mplayer/en/menc-feat-enc-libavcodec.html
Contrary to libavcodec's video codecs, its audio codecs do not make a wise usage of the bits they are given as they lack some minimal psychoacoustic model (if at all) which most other codec implementations feature.However, note that all these audio codecs are very fast and work out-of-the-box everywhere MEncoder has been compiled with libavcodec (which is the case most of …
Libavcodec Documentation - FFmpeg
https://ffmpeg.org/libavcodec.html
The libavcodec library provides a generic encoding/decoding framework and contains multiple decoders and encoders for audio, video and subtitle streams, and several bitstream filters. The shared architecture provides various services ranging from bit stream I/O to DSP optimizations, and makes it suitable for implementing robust and fast codecs ...
