BLEASS Multiband Compressor is the perfect tool for injecting loudness, power and punch into your mixes, stems and tracks. Whether you are creating music on-the-move on your iPad, producing your masterpiece in the studio, or doing both, BLEASS Multiband Compressor dispenses detailed precision control over your music's dynamics. One of the secret weapons of professional mix and mastering engineers, multiband dynamics processors have various advantages over conventional broadband processors. By separating your audio into three frequency bands, and processing each independently, BLEASS Multiband Compressor ensures that loud passages and transients in one frequency range do not impact on how the other bands behave. This eliminates the "volume pumping" effect often exhibited by broadband compressors, making BLEASS Multiband Compressor the perfect tool for processing drum kits, synths, pianos and – of course – full mixes and stems. The plugin works brilliantly with other sources too, from solo instruments to vocals and spoken voice. Unusually for a multiband processor, each of BLEASS Multiband Compressor's three bands features a dual stage dynamics processor. This consists of an Above stage that senses for and processes signals whose level exceeds the Above threshold, and a Below stage that senses for and processes signals that are quieter than the Below threshold. Additionally, each stage can operate as either a compressor or, by dialing in Ratio values below 1:1, an expander. Altogether this makes for phenomenally versatile control over the volume and loudness of your mixes, stems and parts. Another innovative feature of BLEASS Multiband Compressor is its flexible sidechain system. This allows you to choose which bands will key from the input signal in the normal way, and which will key from a filtered and/or external signal. This is ideal for corrective work such as controlling resonances, sibilances and other unwanted artefacts, but is also a fabulous creative tool, allowing for stylish ducking effects and ultra-deep dynamics control. Rounding things off, the plugin provides comprehensive output level and dry / wet balance control, along with a soft clipping feature that ensures overly-hot signals don't become nasty and harsh, but instead take on a classic valve-like saturation character. BLEASS Multiband Compressor stands out for its great sound, innovative features, versatile dynamics control, and exceptional efficiency.
