Your goal will be to write a software which gets a video file (MPEG2 TS), and analyzes audio in this file. The software will simply write to stdout, each 5 seconds (time interval configurable by commandline parameter) what is current audio volume in dB (decibel). Example output: 0s:12dB 5s:25dB 10s:13dB 15s:59dB ... The software will work in Linux and will be opensource so you can reuse some GNU GPL code if you need.

I've been working at audio area for more than 10 years. This project is quite easy to me. I'm just new to this website and I'm trying to build my reputation from this project :-). At present, I'm working in an US audio related company. I'll use the library from ffmpeg to demux and decode the audio from m2ts file. The decoded audio might be multiple channels. I may need to downmix them to mono channel. I can also give dB value for each channel based on your request. Maybe you'll have other similar requests, e.g. display loudness, etc. I can always meet your request! Cheers, Richard

As far as I understood the project, the use of ffmpeg (libavcodec and libavformat, both at least LGPL) would be suitable. Using this strong library the software is ensured to be fast and lightweight.

Hello Sir... I'm very sorry about last time, but I couldn't help it. However, for this project... I have excellent C++ skills... but not much skill in audio processing... If you're interested sir... I can make a quick prototype in a week or so (before awarding project), and you test it and tell me to complete it if you're satisfied (after awarding project). Best Regards.
