Critic Reviews

Source Audio Spectrum Intelligent Filter

soundonsound.com

The Source Audio Spectrum Intelligent Filter successfully modernizes the classic envelope filter concept, delivering a user-friendly interface packed with versatile features. Its ability to create a wide range of sounds—from funky wah effects to ambient tones—makes it a standout choice for guitarists, bassists, and synth enthusiasts alike. The MIDI compatibility and preset storage enhance its functionality, allowing for greater customization. However, the complexity of its numerous options may overwhelm some users, and the monophonic pitch-shifter might not track chords effectively. Overall, it’s a powerful tool that excels in creative sound manipulation while requiring a bit of patience to master.
