Hi, It's really not that easy, but such tool exists: http://www.sevana.fi/audio_speech_codecs_quality_analysis.php It can compare two audio files and give % of similarity whether you want to test your codec quality or just compare two audio files (like original and received at destination of VoIP channel). It's also available for Linux. Hope this helps. Regards, Vallu
