Description

Synthesis is part of modern music creation, and this course provides a simplified overview of shaping waveforms into tones. Instructor Scott Hirsch explains how attack, sustain, decay, and release, or ASDR, are used as the foundations of waveform synthesis, then shows you how to use them to construct custom sounds and patches for your music. Scott offers an overview of how ASDR shapes tones by modifying the shape of your base, unaltered sound. He goes into how the attack property modifies the onset of your base sound. Next, he covers how the sustain property fine-tunes the length of time your sound persists and how the decay time interacts with the sustain level. Scott teaches you how the release time affects the sound after the note is let go. He steps you through how an envelope using ADSR is used in another application and discusses the timing of a filter. In conclusion, Scott offers an overview of how oscillators, filters, and more add further nuance and depth to a synthesized waveform.

Scott Hirsch is a recording and mix engineer, sound designer, and musician. After starting out in post-production at BAVC in San Francisco, Scott relocated to New York City in 2007, where he honed his craft as a film sound designer. As he obtained a master’s degree focused on spatialized audio in post-production at New York University, Scott embedded himself as a sound fixture among the New York independent film scene. While moonlighting in a 5th Avenue commercial post-house (Creative Media Design), Scott edited, sound designed, and mixed films by directors Rick Alverson, Joe Wladyka, Trey Edward Shultz, Andrew Renzi, Sam Fleischner, Pamela Romanowsky, Matthew Porterfield, Francis Bodomo,Adam Rapp, Lawrence Michael Levine, Jonathan Caouette, Chris Mason Johnson, Lucy Walker, and many more. These films played and won multiple awards at the Cannes, Sundance, Berlinale, Tribeca, and SXSW festival circuit with the films Scott worked on over the last seven years. After obtaining his masters degree, Scott went on to teach multiple courses in sound at NYU. Scott is also a musician and music producer, and in 2014 recorded a Grammy nominated album by folk legend Alice Gerrard. His first solo record Blue Rider Songs was released in August, 2016, and his follow up, Lost Time Behind the Moon in December, 2018. He has also performed on and produced four full length albums and several eps by band Hiss Golden Messenger. Scott is a firm believer in sharing his knowledge and experience through education. He has taught as an adjunct professor at NYU's Steinhardt music technology program, as well as Stephen F. Austin University's music and media department and continues to be involved in both programs. Scott is an active author of audio related courses on Linkedin Learning.
