Hi everyone, my name is Han. I’m a senior majoring in Economics. I’m minoring in film studies, music, and business (yes, I’m a video person). I’m taking this class because I’m interested in creating soundtracks for my film projects, which can either be conventional experimental documentaries or live installments of visual and sonic creations. I don’t have a strong background in Western music but I play various non-Western percussion instruments (Korean, Latin American, African, etc.). I look forward to learning a lot from Professor Ernste and my peers in this class. Thanks!

Sinusoidal Partial Editing Analysis and Resynthesis
for MacOS X, MacOS 9 and Windows

Downloads (free) here.

Be sure to read the “help” page for SPEAR containing keystrokes, hints, and solutions to common problems in SPEAR and analysis/resynthesis generally.

SPEAR is an application for audio analysis, editing and synthesis. The analysis procedure (which is based on the traditional McAulay-Quatieri technique) attempts to represent a sound with many individual sinusoidal tracks (partials), each corresponding to a single sinusoidal wave with time varying frequency and amplitude.

Something which closely resembles the original input sound (a resynthesis) can be generated by computing and adding all of the individual time varying sinusoidal waves together. In almost all cases the resynthesis will not be exactly identical to the original sound (although it is possible to get very close).

Aside from offering a very detailed analysis of the time varying frequency content of a sound, a sinusoidal model offers a great deal of flexibility for editing and manipulation. SPEAR supports flexible selection and immediate manipulation of analysis data, cut and paste, and unlimited undo/redo. Hundreds of simultaneous partials can be synthesized in real-time and documents may contain thousands of individual partials dispersed in time. SPEAR also supports a variety of standard file formats for the import and export of analysis data.

Read more in the ICMC paper “Software for Spectral Analysis, Editing, and Synthesis.” (pdf) or in the dissertation paper Spectral Analysis, Editing, and Resynthesis: Methods and Applications (dissertation).

Hello to the world. My name is David, and I’m a junior in the ILR School. I’ve always wanted to take this course, but I’ve never been able to until now. I do come from a music background–I play piano, guitar, sing, and the ukulele–but I want to seriously look into producing music now. I’m excited to see what’s to come this semester and hope to learn a lot as well.


Hi everyone! My name is Aarohee and I’m a senior in the College of Arts and Sciences. I’m majoring in Biology and Psychology with minors in Spanish and Music. I’m taking this class because I want to learn more about DAWs, music performance techniques, and studio set-up. I have previous music experience in piano, violin, singing, and music production. I look forward to this semester!

Hi all,

If you’re curious, here is the link to “Turn It Around” by Lucius, which I covered for Project 2.

Thanks for your feedback today!



Studio and lab issues resolved

Earlier today, a student reported issues in the library lab and studios, including 1) Live 9 licensing problems, 2) Reason network licensing (library lab), and 3) Rewire sharing between Live 9 and Reason.

All issues have now been resolved. All studios are repaired, the library lab license server is back online, and Rewire has been confirmed to work, once again, in all three studios.

– Please be sure to use Live 9 for the remainder of the semester, particularly if you are using Rewire.

– If and when issues of this kind (issues affecting the usability of the labs for any user) come up I certainly appreciate hearing about them so they can be resolved immediately. The more detailed your input the more quickly we can resolve the concern.

— Professor Ernste

P.S. While solving an issue in the lab, someone asked about the Network Drive being unavailable. Please see the FAQ on that issue if that happens again.

tristan perich at cornell

hi everyone– i just wanted to write a quick post to remind you about tristan perich’s residency at cornell this weekend. tristan is one of the most celebrated young artists working in digital art and electroacoustic music today, and it’s a great opportunity to hear some of his work, hear him speak, or meet him while he’s on campus.

i’m also really pleased to be putting on a concert featuring his music. tristan will perform his piece for two percussionists and 1-bit electronics (joined by prof. mike compitello), and there will also be performances of a large portion of his music for keyboard instruments (including the piece for three toy pianos and 1-bit electronics that i posted earlier in the semester!) performed by myself and the other two doctoral students in my program. i am particularly excited to be playing his piece ‘dual synthesis’ (an *extremely* demanding work for harpsichord and electronics) for the first time.

you can find information on the residency (including the composers forum lecture on nov 7 at 1:30PM and the concert on nov 8 at 8PM) at this link:

you can also learn more about tristan and his work here:

hope to see you!

Project One

We ran out of time during section, and it’s too large to directly upload to this blog, so here’s my piece for Project One:

Perhaps ‘Sturm und Drang’ might be a bit much, but I think the thunderstorm sounds justify the dramatic title. Also, I couldn’t think of anything else, so there.

I got the following tracks from Trifonic: vocals, “ambiance”, synth strings, bass, kick, and guitar. I found recording of a thunderstorm on the sound library–thank you, Dave Welsh! I found a track called “breath” that featured two raspy breaths in quick succession. I used those as a sort of heartbeat at the start and end of the piece. I don’t know whose track that is, but thank you, and feel free to comment on this post and take credit; that track was really cool, so you definitely deserve it.

There’s also a pulsating drone throughout. I used drumsticks and chopsticks and recorded myself running the sticks across the keyboards (the one for the iMac, the Yamaha keyboard and the MIDI input device). That track was originally supposed to be rain, but I put resonators on it (Valhalla and Rome, I think), and really liked the sound, so I removed the percussive attacks and made it unrecognizable by adding more reverb. I really like reverb. And resonators. Resonators are cool.

Let me know what you think!
