Hello programs,
Join us on Monday, July 25th at 6pm in the MC Comfy Lounge for an exciting
prof talk by Richard Mann on Open Source Computer Sound Measurement. The
abstract for the talk is below. We will follow this up by an EOT event with
dinner and board games! Last event of the term, get hype.
Abstract:
>
>
> An ideal computer audio system should faithfully reproduce signals of
> all frequencies in the audible range (20 to 20,000 cycles per second).
> Real systems, particularly mobile devices and laptops, may still
> produce acceptable quality, but often have a limited response,
> particularly at the low (bass) frequencies.
>
> Sound/acousic energy refers to time varying pressure waves in air.
> When recording sound, the acoustic signal will be picked up by
> microphone, which converts it to electrical signals (voltages). The
> signal is then digitized (analog to digital conversion) and stored as
> a stream of numbers in a data file. On playback the digital signal is
> converted to an electrical signal (digital to analog conversion) and
> finally returned as an acoustic signal by a speaker and/or headphones.
>
> In this talk I will present open source software (Octave/Linux) to
> measure the end-to-end frequency response of an audio system using the
> Discrete Fourier Transform. I will demonstrate the software using a
> standard USB audio interface and a consumer grade omnidirectional
> microphone.
>
> This is joint work with John Vanderkooy, Distinguished Professor
> Emeritus, Department of Physics and Astronomy.
Hope to see you there!

Hello programs!
We have a couple of great talks coming up soon.
On Thursday, July 2st at 6pm in MC 4045, Bill Cowan will be giving a talk
on Notorious CS452. Abstract below:
CS452, aka the trains course, has for some time enjoyed notoriety as a
playground for over-achieving masochists. To maintain its reputation it
receives a periodic upgrade, which is now due. This talk discusses possible
directions for the upgrade in the context of the philosophy that has guided
its evolution over the decades of its existence.
If you've taken trains, want to take trains, or even just want to learn
about the course spoken of in hushed whispers... this talk is for you.
For the last week of classes, we have a double-decker event for you. On
Monday, July 2th, we have a talk by Richard Mann on computer audio
(abstract and more details to come), and an end of term event right after.
Come celebrate the end of term with all your CSC friends, and learn a thing
or two while you're at it!
Hope to see you there!
