REQ: Pulsar Audio Mu [MacOS M1 ARM Native)

There are several reasons to use a variable-bias tube compressor. One is the exceptional compression transparency that this kind of compressor can achieve, even when pushed into extreme gain reduction. Another – and perhaps the most common – is their ability to add cohesion or “glue” to buses, whole mixes and masters.

Pulsar Mu is a stereo compressor operating in either Left/Right or Mid/Side modes, designed with mixing and mastering applications in mind, but also flexible enough for tracking. It can be used for levelling, limiting, or just to add a bit of analog warmth with its emulated tube signal path.

While reproducing the accurate SIFAM metering of the original unit, Pulsar Mu also provides a more modern visualization mode for fine-tuning compression settings, representing the waveform and gain reduction both over time and instantaneously.

Pulsar Mu also offers various options that apply to the sidechain signal. A popular mod of the original device was to add a high-pass filter, but Mu goes even further, offering a more complete equalization section, enabling to precisely adjust the compressor’s response to bass, midrange and treble using only four knobs.

Another addition is the possibility of advancing (look-ahead) or delaying (look-behind) the sidechain signal. This enables you to take ultimate control over transients, letting the compressor start to react before they happen, over even after they happen, opening up all kinds of creative uses.
