A JSFX telephone effect plugin for REAPER that features:
* Frequency (700 Hz – 3.0 kHz): Sets the center frequency of the bandpass filter.
* Resonance (0.2 – 4.0): Controls the Q factor of the bandpass filter. Higher values produce a more resonant telephone sound.
* Output Gain (dB): Sets the final output level of the plugin from -30 dB to +30 dB to compensate for volume changes.
* Hidden HPF & LPF: The high-pass and low-pass filters are fixed internally and hidden. They work alongside the bandpass filter to reinforce the frequency shaping.
* GUI Bypass Button: A smooth bypass button for toggling the effect on or off without audio clicks. It is available for automation as "Bypass (Smooth)" in the plugin's parameter list.
* Minimal CPU usage.
You can grab it for FREE.
