Good day.

I aim to develop a software that can visualize the data portion of an mp3 file. I've done a good amount of internet research but I haven't found any good source. Before, I managed to create a software that can visualize uncompressed canonical wav files (8-bit, 16-bit, mono and stereo) and I want to take it further by being able to visualize mp3 files.

I know that mp3 files are not as straightforward as compared to uncompressed canonical wav files. Anyone who knows a good starting point in visualizing mp3 files is very welcome to share his or her knowledge.

I'm developing in C++.

  • Visualize how? What is your question? How to decode MP3 to raw PCM? Or how to "visualize" audio? – Brad Feb 13 '13 at 05:26

You want to decode the mp3 file to uncompressed WAV and then visualise that. Have a look at this question for some options: https://stackoverflow.com/questions/4936177/what-is-a-good-platform-independend-c-library-for-mp3-decoding

You may consider LAME to decode your input mp3 file into raw pcm (uncompressed) and visualize it.
