Acon Digital Mastering Suite - Electronic Delivery

Acon Digital Mastering Suite consists of five plug-ins for audio mastering that were designed for ultimate signal transparency. Acon Digital Mastering Suite is available in 32 and 64 bit versions, as VST, VST3 or AAX for both Windows and OS X or as AU plug-ins for OS X.

Dynamics

Dynamics is a combined compressor, expander or gate. The look-ahead can be set anywhere from 0 to 30 milliseconds and the intelligent algorithm ensures a band-limited gain signal which reduces potential distortion to a minimum even with minimal attack and release times. You can use up to 4 times oversampling to further reduce distortion. The side chain signal can be either internal or external and there’s a full blown side chain 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.

• Intelligent look-ahead algorithm that reduces distortion to a minimum
• Latency and look-ahead can be set anywhere between 0 and 30 milliseconds
• Powerful side chain filtering with full EQ section — low cut, low shelf, bell, high shelf and high cut filters
• Oversampling up to 4X
• Threshold and ratio can be adjusted directly in the level history curve or using knobs
• Acts as a compressor for ratios over 1:1 and as an expander or gate for ratios below 1:1
• Adjustable soft knee specified in dB
• Adjustable attack, hold and release times specified in milliseconds
• Channel linking can be set between 0 (no link) and 100% (all channel share the same gain control signal)
• Adjustable make-up gain specified in dB with optional automatic mode

Multiband Dynamics

Multiband Dynamics is the multiband extension of Dynamics which allows dynamic processing in up to four separate bands. You can freely set the cross-over frequencies and even 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.

• Dynamic processing in up to four separate frequency bands
• Spectral analyzer with frequency band indicators, freely adjustable cross over frequencies and freely adjustable filter slopes
• Intelligent look-ahead algorithm that reduces distortion to a minimum
• Threshold and ratio can be adjusted directly in the level history curve or using knobs
• Acts as a compressor for ratios over 1:1 and as an expander or gate for ratios below 1:1
• Adjustable soft knee specified in dB
• Adjustable attack and release times specified in milliseconds

Limit

Limit is a transparent limiter with intelligent look-ahead in the range 0 to 30 milliseconds that reduces distortion to a minimum. The limiting is performed in a two step process with a pre-compressor follower by the actual peak limiting algorithm. You can use up to 4 times oversampling for true peak limiting and to further reduce distortion.

• Intelligent look-ahead algorithm that reduces distortion to a minimum
• Pre-compressor stage with adjustable attack and release times specified in milliseconds
• Channel linking can be set separately for pre-compressor and peak suppression with values between 0 (no link) and 100% (all channel share the same gain control signal)
• Oversampling up to 4X for true peak limiting
• Graphical history curve showing level and gain reduction for the past 5 seconds

Equalize

Equalize is a parametric equalizer. Unlike other equalizers, 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, choose to preserve the phase relationships in the linear phase mode or use the unique mixed phase mode. The mixed phase mode allows you to set the latency freely in the range 5 to 120 milliseconds while preserving the phase relationships as far as possible. That gives a unique control over potential pre-ringing artifacts which is a common problem with linear phase filtering.

• Up to twelve equalizer bands
• Eight different band filter types (low cut, low shelf, peak, tilt, bandpass, notch, high shelf and high cut)
• Band frequency, gain, bandwidth, resonance and filter slope is freely adjustable for each band
• Three different filter modes, minimum phase, linear phase or the novel mixed phase
• Adjustable latency and pre-ringing time in mixed phase mode
• Zero latency in minimum phase mode
• Channel mode (mid, side, left, right or full processing) can be set independently for each band
• Multiple selection of bands
• Resizable graphical user interface
• Solo and bypass modes
• Optional automatic make-up gain
• Optional gain to bandwidth linking
• Two spectrum analyzers that can analyze the input or output signal from the mid, side, left or right channel
• Graphical visualization of the equalizer frequency response
• Preset manager and a large number of factory presets
• Save, load and categorize user presets

Dither

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 is visualized graphically.

• Triangular Probability Density Function (TPDF) dithering
• Physcho-acoustic noise shaping filter with adjustable filter length and maximum filter gain
• Graphical representation of the noise shaping filter’s frequency response
• Supported target bit depths: 8, 12, 16, 20 and 24 bits
