The Sonnox Fraunhofer Pro-Codec plug-in makes it possible to precisely audition codecs in real time. This breaks away from the current time-consuming cycle of having to encode the mix to mp3/AAC, preview it, tweak it and then go back and re-render. The entire process is accomplished 'on the fly, ' and frees the engineer to focus on producing a compensated, optimized mix.
The Pro-Codec plug-in enables mix and mastering engineers to audition up to five codecs in real time within a DAW environment, produce an optimized mix and batch encode to multiple formats simultaneously. All major codecs, including mp3, mp3 Surround, AAC-LC and HE-AAC are supported, as are lossless codecs such as mp3 HD and HD-AAC.
Sonnox has developed an intuitive FFT display to illustrate the input signal, output difference signal and a unique graphical indication of the audibility of codec-induced noise. Bit-stream integrity meters reveal potential decode overloads. Instant A-B auditioning enables engineers to glitchlessly switch between codecs. A 'blind listening mode' (ABX) augments codec comparisons.
