DxII Codec is a modern digital equivalent of the traditional dbx-II/Disc system which was one of the outstanding analog audio tape/LP noise reduction systems. The software is capable of decoding/encoding dbx type-II or type-Disc formatted audio in digital domain, with ease, quality and efficiency. Benefiting from the proprietary DSP engine and intuitive GUI, the process can be accomplished real-timely with smooth user interaction.

Deeper optimal result can be achieved by using the advanced tools that come with the software, as specified below:

• The dual-meter visualizes potential risks of dynamic-range overload or underload, with adjustable means for instant correction.
• The Azimuth and Gap-Loss tools can compensate minor imperfection of analog tape player used for digitizing audio tapes.
• The Play Trim is another tool for compensating weakened signal on aged pre-recorded tapes.
• The EQ Converter offers digital translation between 120μs and 70μs IEC standards — if such a flexibility is not found on a given tape player/recorder.

• The RMS timing slider offers optional flexibility to adjust the compander’s tracking speed.
• The built-in tone generator offers 1kHz 0 dB Reference Level signal for easy calibration.

Most of the fine-tuning tools can work independently of the dbx-II/Disc codec, which can also be applied for refining non-dbx formatted audio.

DxII Codec is a stand-alone GUI app without relying on any other DAW host. It allows the computer to serve as an external(outboard) dbx-II/Disc unit in one of the following four modes:

• Audio-In to File (a digitizer/recorder).
• File to Audio-Out (a player).
• File to File (an off-line processor, with batch capability).
• Audio-In to Audio-Out (a through processor, with slight delay).

Currently supported audio file formats are:
WAV, FLAC, AIFF: up to 96k/24bit.
MP3, AAC, M4A: up to 48k/VBR.

• Excluding some proprietary variants having the common file extensions, or additional format-normalization may be required.

A VST plugin is also available as an optional software component of the application.

The software comes with embedded user manual on each major functions.

Please note that this software is suited for the consumer grade dbx type-II or type-Disc, which is not compatible with the professional grade dbx type-I.
