The recovery control modifies the long-term timing of the envelope processing. Generally the most audible effects occur from the mid position of the overshoot control upwards. Because the TransMod process is so rapid, low settings may not be heard because the duration of the transients being affected are too short. The adaptive nature of the processing, over both level and time, allows optimal settings of the timing value to be achieved for complete tracks and even complex final mixes.
Increasing the overshoot period allows transient enhancement to occur over longer periods, therefore providing a method to tune the action to suit the programme material and produce the required effect. For example, a small overshoot time can accentuate short-term events in the programme for small percussion instruments such as bells, whilst largely ignoring large and softer transients from instruments such a drums etc. A short overshoot period will enhance (or reduce) transients for a very short time and cause only the leading edges of the transients to be modified. The overshoot time sets the period over which the dynamic changes occur, depending on the input programme dynamics. With the ratio control in its central position (0), the TransMod process does not affect the signal at all. So, for example, when the ratio control is set at +1, a drum ‘thwack’ that has a peak of 10dB above the average level will produce a level increase of twice that (20dB) at the output, because the gain during the transient will be increased by the same amount as its level difference.įor negative ratios the reverse is true, and for a negative ratio of -1 the drum attack transient would be reduced to the corresponding average level of the signal, and will therefore be removed. Positive values will increase the gain of the signal during transients. The ratio value represents the linear dB ratio by which the output gain will be modified by instantaneous changes in the input level. Increase overall modulation potential by the reduction of very short peaks Harden up and give life to dull or flat-sounding recordings and mixes, without the unwanted changes in overall timbre associated with multi-band compression techniques Produce rounded and dynamic percussive effects Increase or reduce the effects of ambience Radically change the dynamics of instrumentsĪccentuate or flatten attacks and transients Such effects are easily achieved with the TransMod because its purpose designed adaptive processing acts on differential information in the programme, so that the overall long-term programme level is minimally affected, and sensitivity to control parameters is drastically reduced. The application was developed to address a common situation where there is a need to selectively tighten up percussive instruments or soften the unwanted percussive effects of acoustic musical instruments. The effect is to bring transient events in the programme forward, or push them to the background, such that the attack of instruments can be accentuated or softened depending on the settings provided. The Sonnox Oxford TransMod is an application that allows the dynamic level of signals to be modified, over time, by transients in the programme material.
