LCF by Analog Obsession: Vintage Filter with Character

In the world of digital audio, where precision and transparency are the norm, it is sometimes the vintage character that adds the unique spark that is so lacking. The LCF plugin from Analog Obsession is just such a tool. Designed as an emulation of a vintage solid-state high and low-pass filter, LCF brings to your tracks not just spectral correction, but also a special analog flavor.

This plugin not only effectively performs the filtering functions, but also has a unique ability to “sweeten” the high frequencies and remove unwanted harshness even when the filters themselves are not activated! This makes it a valuable tool not only for surgical correction, but also for overall tonal balance improvement and the addition of pleasant analog warmth.

Key Features and Capabilities

LCF offers a simple and intuitive interface based on the selection of fixed filter frequencies. This approach, characteristic of many classic devices, allows you to quickly find the desired sound without unnecessary adjustments.

  • Low Pass Filter: Allows you to gently remove unwanted high frequencies, leaving space for the main elements of the mix. Available options:
    • Bypass
    • 8,000 Hz
    • 6,000 Hz
    • 4,000 Hz
    • 2,000 Hz

    The choice of frequency depends on the instrument and the desired effect. For example, 8 kHz or 6 kHz may be suitable for removing excessive “airiness” or sibilants on vocals, while lower frequencies can be used to form a denser sound of guitars or synthesizers.

  • High Pass Filter: Helps to get rid of hum, excessive low-frequency noise, or simply clear the bottom of the mix, freeing up space for the bass and kick drum. Available options:
    • Bypass
    • 45 Hz
    • 70 Hz
    • 160 Hz
    • 360 Hz

    The frequencies are carefully selected for typical tasks: 45-70 Hz are often used to clear sub-low frequencies, and 160-360 Hz are used to remove “muddiness” and resonances in the lower mids.
