Sonnox Fraunhofer Pro-Codec

Sonnox has announced the release of the Fraunhofer Pro-Codec, a plug-in designed for the real-time auditioning, encoding and decoding of audio signals using Fraunhofer codecs.

Mix and mastering engineers may now audition up to five codecs in real time within a DAW environment. The Sonnox Fraunhofer Pro-Codec plug-in enables the production of mixes, and provides the option to batch encode to multiple formats. Major codecs, including: mp3, mp3 Surround, AAC-LC and HE-AAC are supported, as are such lossless codecs as mp3 HD and HD-AAC.

Sonnox has devised a FFT display which illustrates the input and output difference signals and a graphical indication of codec-induced noise audibility. Bit-stream level meters display the possibility of decode overloads. A-B auditioning enables engineers to switch between codecs, or input and codec. A blind listening mode (ABX) further supports codec comparisons.

Features:

Supported Codecs:
- mp3, mp3 Surround, AAC-LC, HE-AAC, and HE-AAC v2.
- mp3-HD and HD-AAC (Lossless Codecs).
Ability to select up to five codecs for simultaneous export, in real time, to encoded files.
Auditioning with glitchless switching.
Ability to audition the difference between input signal and codec output.
AB auditioning in real time between codecs, or between codec and input signal.
ABX mode for blind statistical testing.
Graphical displays include:
- Display of the Input signal and Diff signal.
- Indication of the audibility of audio removed by the encoding process.
- Bitstream levels and ability to compensate for overloads.
- Indication of filesize or datastream compression.
- Phase metering.
Off-line encoding and decoding.
