Playing G.723 audio files

brotrevor — Mon, 24 May 2010 19:08:06 GMT

I'm asking this question not as much of a developer but as an end user.

I receive audio files of recorded conversations on a regular basis from a large American corporation. These files are .wav files and will play on Windows XP, but not on Windows Vista. Windows Media Player gives me the error link: http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7008&id=C00D10D1&contextid=84&originalid=80040200&codec=42

Researching Intel g.723 has brought me here.

Is there a way to obtain the g.723 codec for playback purposes only? If not, is there a way to use IPP to develop a simple player for audio files that utilize that codec? Please point me in the right direction.

Many Thanks,

Trevor

Trevor,

You might check the IPP Speech Coding samples:

http://software.intel.com/en-us/articles/intel-integrated-performance-primitives-code-samples/

For umc_speech_rtp_codec application, it can decode the the RTPDump files (with g.723 data) into a wave file.

but please note, the sample code is used for the developers to develop the G723 codec, not the application for the end user.

Thanks,

Chao
