Snake Extension – What I have learned in the Spring semester

I taught Digital Signal Processing Theory class in the last Spring. I have never studied this hard to teach a course. As a result, I learned (or relearned) about DSP quite a bit. More specifically, I learned to appreciate elegance of “classic” techniques, such as AM, FM, sample-and-hold, and delays. I think I can explain them in digital terms. Most importantly, I learned that digital signal processing is all about (good) math.

The best way to wrap up the semester and summarize what I have learned is to make a piece using the new techniques I have learned.

1. To start the piece, I begin with a sinusoid generated with very slow Low Frequency Oscillator (LFO) on its pitch. The LFO’s shape is made with a  wave shaping function using polynomials. The result is an unusual curve pitch pattern.

2. On this polynomial curve, I add sample and hold. The smooth line gets “steps” in terms of pitch. I change the S&H rate to create different rhythms

3. As the piece progresses, I would like to have some frequency modulation gradually fading in.

4. This should sound fun if I have more of them. Here is an example of all the techniques with four sinusoids. The rate of S&H, the shape of polynomial curve, and the modulation rate of FM are randomly selected for each line.

The resulting sound sounded like a good accompaniment for a noisy electronic piece. So I played a no-input mixer and custom synthesizer over the polynomial pads. I also continued the piece with algorithmically drum part that I have developed for Snake and Ox track in my latest album (more about this track later).

Here’s the final result, Snake Extension. I think I’ll add this to my solo repertoire.

A new album is coming!

jwp-overundertone-at4-lq

My new solo album titled Overundertone will be released on this coming Monday (April 13) by NoRemixes label.  If last album, 120V was a collection of my old pieces, this album is a representation of where I am now. Almost all the tracks in the album use computer-synthesized sounds. Just like anything with with the computer, the sounds in this album are precise, digital, almost to the point that it feels unnatural and inhuman. But I like that aspects of computer music.

I think I made an interesting album. I hope you like it, too.

 

A new album is out

120V is out now on Amazon as a downloadable album.

This is a compilation album of my solo works from 2002 to 2013.  All tracks except one are available for streaming in Soundcloud (The SCloud has a better streaming quality, and you can listen to the entire track). The album-only track, also named as 120v, is a no-input mixer piece that is quite different from all other works included in this album.
Visceral Media also made a video interview about me and my album. The guest in this video also appears in some of my works.

Please listen, share, review, and purchase the album!

A New Album is on the Way

Visceral Media Records will be releasing my new album in few weeks. The album is titled 120V, and it is a “best of” album that contains my works composed in the past 10+ years.  It also has a new track for no-input mixer and computer (marked with * in the track listing).

The album has quite a variety in terms of electronic music style. I feel very happy to share an album that contains pieces that reflects who I was and who I am. My life and music has changed immensely since I started to make electronic after plugging things into 120V outlets in the US.

Hunchback of Notre Dame … A Mute Play

Here are some pictures of my recent theatre collaboration. Adam Vidiksis and I made music for the Hunchback of Notre Dame … a Mute Play. It was produced by the Renegade Company. As you may find in the Company’s website, the play received numerous positive reviews. I am very happy about the resulting collaboration. The video and audio recording of the piece is one the way, but I think that the following pictures can show some aspects of the play.  As for the music, my portion of electronic part was coupled with Adam’s imaginative percussion and his own electronics.
