![]() Depending on their respective positions, the Halo and Rate controls combine with Color to add pleasing, tape-like pitch modulations to the repeats. As with most all of the Mimeophon's controls, the Color's response is affected by-and is affecting-its relationship to other settings. A closer listen reveals a much more subtle side to the timbres. For the majority of the Halo range, the effect is kept out of the Mimeophon's feedback chain, but at settings approaching the maximum changes this behavior and allows some of the "smeared" signal to enter the feedback path, giving rise to more dense, lush reverberated tones.Ĭolor, at first sweep, sounds similar to a low-pass filter, ranging in tone from very dark at to bright and shimmery. As the Halo amount increases, the initially subtle, slightly reflective character of the sound gets progressively smoothed and with the knob set midway, the signal isn't obscured or lost in the mist, but gains a pleasing stereo depth. Halo "smears" the sound and fills in the space between individual notes with a washy haze. The Mimeophon has three main areas of sound processing: The main "delay" section consisting of the Repeats, Zone, and Rate sections, Halo, and Color. While it is possible to consider the Mimeophon in terms of discrete parts, each section of the unit interacts with the others in significant-sometimes subtle, sometimes extreme-ways. Make Noise modules can appear a bit cryptic at first, but the Mimeophon is for the most part intuitive, ergonomic, and most importantly, damn fun. Despite everything being fit into a modest 16HP, the Mimeophon feels great and retains an easy performability. In addition, the Mimeophon has a few buttons at the bottom labeled Flip, Hold, and Skew, a Tempo in for clocking the delay line, and a Rate output. The Mimeophon features of a pair of stereo ins and outs, a wet/dry Mix knob, and five main control sections: Repeats, Zone, Rate, Halo, and Color. ![]() Made in collaboration with SoundHack and billed by Make Noise as a "multi-zone color audio repeater," the Mimeophon blurs the line between delay module, effects unit, audio looper, and synth voice, and offers a veritable universe of sound sculpting possibilities. Version 1.0.Continuing in the vein of Make Noise's latest module releases, the Mimeophon is a stereo module fitted with an attractive black panel and adorned with their trademark font and hieroglyphic labeling.If you wonder how, please read the wonderful " Pitch Shifting Using the Fourier Transform" article.īelow, you can find a simple diagram showing how the audio is processed. It's not the scope of this article to tell you how the pitch shifting algorithm in the PitchShifter class works. PitchShifter.PitchShift(PitchShift, offset, count, 2048, 4,, buffer) Int samples = mSource.Read(buffer, offset, count) įor ( int i = offset i < offset + samples i++)īuffer = Math.Max(Math.Min(buffer * gainAmplification, 1), -1) This enables to hear what you speak into the microphone from the speakers with minimum delay.įloat gainAmplification = ( float)(Math.Pow( 10. When you click the Start button, the application initializes the capture device in "exclusive mode" to enable minimum latency. You can change this mp3 file with your favorite karaoke song to sing like a chipmunk or Darth Vader. When you click the "Add Sample Mp3" checkbox, the sample mp3 file starts to play and stops when you uncheck it. Play with the "Pitch" and "Gain" sliders to change your sound. Select your preferred microphone and speaker and click Start.ĪTTENTION: Please use a headset with a microphone to avoid nasty feedback on your speakers. ![]() It uses Wasapi to capture and play audio so you need at least Windows Vista to be able to run. This is how the application looks when you start it. This application uses the excellent C# audio library CSCore to capture, play and process audio and the pitch shifting algorithm written by Stephan Bernsee (see references). I wrote this application to change my voice in "real time" either to a chipmunk or Darth Vader using an audio pitch shifting algorithm. I love the voices of "Alvin and The Chipmunks" and "Darth Vader".
