Here are a series of files to give you some idea of the kinds of comparisons that can be made using the Sonnox Fraunhofer Pro-Codec plug-in. Note that all these files are 16-bit/44.1kHz WAVs bounced out of my DAW system while monitoring the plug-in's output, so you should be able to import and compare them easily within any multitrack studio software.

ProCodec_InputPCM

The source audio for these tests: a section of my June 2011 Mix Rescue remix, at 16-bit/44.1kHz resolution. It's being passed through Sonnox Fraunhofer Pro-Codec with the plug-in's onboard bypass mode ('Input Monitor') enabled.

ProCodec_MP3_CBR_128kbps_HighQuality
