Pre-Class Music • Keith Kothman, Audio from Interludes
Upcoming Events • AES Student Chapter Meeting, April 12, Noon (MET) • Gene Radzik, Dolby Labs • Evolution of High Resolution Digital Audio in an Era of Multichannel Surround • EM | Four, April 15, 8 pm, Pruis • AES Student Chapter Meeting, April 17, 2 pm, (MET) • David Miles Huber
Spectral Filter (Pluggo Plugin) • VST Plugin (available in Peak and DP3) • Convolves input with 512-band IR. • Amplitude of each band of IR can be individually controlled by drawing in window. • Time-smearing is limited to 0.0116099773 seconds (512 samples/44100 samples). • Very useful to eliminate noise, or to create a multiple-peak IR for filtering.
Using the Spectral Filter • In Peak, go to Plug-ins | VST | whatever insert number | Spectral Filter • In DP3, it is available in the audio plugins menu for each track. • Most of your musically useful range is in the lower third of the window.
Spectral Processing in DP3 • Non-real-time effects, accessed through the Audio | Spectral Processing menu choice. • Allows for time compression, expansion (within percentage limits), transposition, and independent formant transposition. • Having independent control over pitch and formants can allow for transposition without losing characteristic timbre, or you can have timbral change without pitch transposition.
Using Spectral Processing in DP3 • Real-Time DSP must be enabled for the soundbite you want to process. • You can time expand or compress soundbites • within the audio track editor by dragging on the end of the color bar for the soundbite. (Useful for setting a soundbite to an exact duration.) • within the Soundbites window by clicking on a soundbite, and selecting Spectral Processing from the Audio Menu.
Using … DP3 (2) • As seductive as the 3D ball-in-room interface is, it isn’t very precise to use. • Set your time and transposition values in the dialog boxes. • You can save and load presets.
Which Spectral Processor to Use? • SoundHack is the best Phase Vocoder. • Peak is the most useful Convolution tool (because it scales output gain to input gain). • Spectral Filter is very useful for precise filtering without noticeable time-smearing. • Drawback: isn’t time variable • DP3 has the only formant shifter.
