The electronic download of Digital Mastering Suite Plug-Ins from Acon consists of five plug-ins for audio mastering. They can be used by engineers, producers, or musicians for mixing and mastering applications on Mac or Window computers, with support for Native 32-bit or 64-bit versions, sampling rates up to 96 kHz, and multichannel audio up to 7.1 surround.
The featured plug-ins include: Dynamics, a combined compressor, expander, or gate. The lookahead can be set anywhere from 0 to 30 milliseconds, and the intelligent algorithm provides a band-limited gain signal which reduces potential distortion to a minimum even with minimal attack and release times. You can oversample up to 4 times to further reduce distortion, and the sidechain signal can be either internal or external. There's a full-blown sidechain equalizer integrated with low-cut, low-shelf, peak, high-shelf, and high-cut filters. The complexity of algorithms is not reflected in the intuitive user interface, which provides graphical visualizations of all aspects of the processing.
Multiband Dynamics is the multiband extension of Dynamics, which allows dynamic processing in up to four separate bands. You can freely set the crossover frequencies, and the filter slopes can be set freely in the range 6 and 48 dB per octave. Multiband Dynamics operates in linear phase mode to avoid phase issues between the processed bands.
Limit is a transparent limiter with intelligent lookahead in the range 0 to 30 milliseconds that reduces distortion to a minimum. The limiting is performed in a two-step process. With the precompressor follower and by the actual peak limiting algorithm, you can use up to 4-times oversampling for true peak limiting and to further reduce distortion.
Equalize is a parametric equalizer you can freely adjust not only center frequency, gain and bandwidths, but also the filter slope for each band. The filter slope can be set anywhere from 3 dB to ultra-sharp 120 dB per octave. You can operate Equalize as a zero latency plug-in. When using the minimum phase mode, you can choose to preserve the phase relationships in the linear phase mode, or alternatively, use the unique mixed phase mode. The mixed phase mode allows you to set the latency freely in the range of 5 to 120 milliseconds while preserving the phase relationships as far as possible. This gives unique control over potential pre-ringing artifacts, which is a common problem with linear phase filtering.
Dither is a dithering plug-in with flexible perceptual noise shaping. You can adjust the maximum gain and the filter length of the frequency response of the noise shaping filter, which is visualized graphically.
Finally, everything you need to tailor your sound with signal transparency is available in the Acon Digital Mastering Suite Plug-Ins.
