Low-pass Filter

The low-pass filter on the RC505 is used to cut off high-frequency components from the input signal, allowing only the low-frequency components to pass through. This can be useful for reducing noise, adding warmth to a sound, or creating a lo-fi effect.

 

Band-pass Filter

The RC505 also features a bandpass filter that allows a specific range of frequencies to pass through while attenuating or blocking frequencies outside that range. The bandpass filter on the RC505 is useful for isolating a specific frequency band in the input signal and can be used for creative sound shaping, such as emphasizing or cutting certain frequencies. It can also be used to remove unwanted noise or hum from a signal in a specific frequency range.

 

Low-pass Filter

The high-pass filter on the RC505 allows high-frequency signals to pass through while attenuating low-frequency signals, useful for removing low-frequency noise and emphasizing high-frequency content in a sound. It can also add a "thin" or "bright" character to a sound by cutting off low-frequency components.

 

 

General

The Filter effect on the RC-505 is a type of audio processing that allows users to manipulate the frequency content of an audio signal. It is a popular effect used in music production and sound design to shape the tone and texture of sounds.

The Filter effect on the RC-505 offers several different types of filters, including Low-Pass, High-Pass, Band-Pass, and Peaking. Each filter type allows the user to attenuate or emphasize certain frequency ranges of the input signal, which can create a variety of tonal changes.

The Low-Pass filter attenuates frequencies above the cutoff frequency, allowing only the lower frequencies to pass through. This filter can create a warmer and more mellow tone by removing high-frequency content.

The High-Pass filter attenuates frequencies below the cutoff frequency, allowing only the higher frequencies to pass through. This filter can create a brighter and more airy tone by removing low-frequency content.

The Band-Pass filter allows a specific frequency range to pass through while attenuating frequencies above and below that range. This filter can be used to emphasize a particular frequency range or to isolate a specific part of the sound.

​

In addition to the filter type, the RC-505 Filter effect also features adjustable parameters such as Cutoff, Resonance, and Envelope. The Cutoff parameter sets the frequency at which the filter starts to attenuate, while the Resonance parameter adjusts the emphasis of the filter at the cutoff frequency. The Envelope parameter allows the filter to be controlled by the dynamics of the input signal, such as the volume or the attack of the sound.

Overall, the Filter effect on the RC-505 provides a versatile and powerful tool for shaping the frequency content of audio signals.
