Build a small educational C program with ALSA (Advanced Linux Sound Architecture) that prints real-time audio levels to the shell

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 7 years. My work is online game developing, and mainly focus on server side, using c++ under Linux environment. I made many great projects using c++, for example, I made the tools which could convert java codes into c++ scripts, of course garbage collection included, this was very similar to a compiler, and was very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

Hi, I am a linux c programmer with alsa experiences. Once I developed a alsa echo bridge. I can satisfy you. Thank you.

Hi. I have programmed audio programming with alsa 1 year before. A part of code is as follows. int main() { int val; printf("ALSA library version: %s\n", SND_LIB_VERSION_STR); printf("\nPCM stream types:\n"); for (val = 0; val <= SND_PCM_STREAM_LAST; val++) printf(" %s\n", snd_pcm_stream_name((snd_pcm_stream_t)val)); printf("\nPCM access types:\n"); for (val = 0; val <= SND_PCM_ACCESS_LAST; val++) printf(" %s\n", snd_pcm_access_name((snd_pcm_access_t)val)); printf("\nPCM formats:\n"); for (val = 0; val <= SND_PCM_FORMAT_LAST; val++) if (snd_pcm_format_name((snd_pcm_format_t)val) != NULL) printf(" %s (%s)\n", snd_pcm_format_name((snd_pcm_format_t)val), snd_pcm_format_description( (snd_pcm_format_t)val)); printf("\nPCM subformats:\n"); for (val = 0; val <= SND_PCM_SUBFORMAT_LAST; val++) printf(" %s (%s)\n", snd_pcm_subformat_name(( snd_pcm_subformat_t)val), snd_pcm_subformat_description(( snd_pcm_subformat_t)val)); printf("\nPCM states:\n"); for (val = 0; val <= SND_PCM_STATE_LAST; val++) printf(" %s\n", snd_pcm_state_name((snd_pcm_state_t)val)); return 0; } Besides opening pcm Device and setting parameters , soud play back and sound recording are working well. Thanks. Message does not be delivered. Why?

Hello I've read your job description carefully. I'm an Linux expert and so confident I could complete your job. Though I never used Ubuntu, but I'm very familiar with CentOS and Fedora.
