Here is a demonstration I found on YouTube which I think is very useful to show the components of a loudspeaker and how it works. http://www.youtube.com/watch?v=3ZQqCyRQFB4& The electrical current flowing through the voice coil creates a magnetic field that interacts with the permanent magnet’s field. As the signal changes polarity, this magnetic interaction forces the […]

A brilliant ALSA developer, Clemens L, has been working on a separate ALSA driver for streaming sound over firewire within the linux kernel. This would mean that the FFADO project would be unnecessary as an addon for JACK audio connection kit to provide support for firewire devices in the future, as there would exist a […]
I have been working on a jack client that uses the GPU to process audio. The benefit of this is that it lightens the load off the CPU to process audio. I used the NVIDIA CUDA toolchain to create a jack-cuda client. Currently I have made a gain plugin that uses 256 parallel threads to […]
A new plugin has been added to the ZamAudio plugin suite, ZAMCompressor. Screenshot: cell phone spying
There does not currently exist a linux driver for Mbox 2 mini. I don’t have the hardware so I am not writing one either. This page is for driver discussion on this model. UPDATE 4/12/2010: The Mbox2 and Mbox2 Mini share the same USB ID and usb endpoints thus they are physically the same device […]
Variation on Happy days. lilyofthevalley you know who you are.
ZamAudio has an announcement to make: Sorry fellow linux users, there will be no more new patches for Digidesign Mbox 2 ALSA sound drivers, as I am focusing on something else. But you can still get the old ones here. Pro Tools and Avid Audio are registered trademarks of Avid Audio, a division of Avid […]
After reading extensively on digital filters, I decided to write my own digital filter using the Bilinear Transform method. What is a digital filter? A regular analogue filter uses passive radio components to filter out certain frequencies of an input signal. A digital implementation of this aims to have the same effect, but it must […]
I decided to write my own audio plugin, a gate/expander, because I couldn’t find a good equivalent plugin. You can download a patch for calf-plugins git tree here. To fetch the plugin code and patch to my version: git clone http://repo.or.cz/r/calf.git calf cd calf git apply path-to-my.patch ./autogen.sh ./configure –enable-experimental make sudo make install I […]
This is my unofficial Digidesign Mbox 2 driver for linux. Please consider donating $5 for further development of open source drivers for Digidesign hardware. Every little bit counts. For those of you who want the raw driver source, here it is as a kernel module [63kB]. It can be compiled for the current running kernel […]
If $$P$$ dollars are invested for one year, at a rate of interest $$i$$, it will accumulate to amount $$A$$ at the end of the year by the following equation: $$!A=P(1+i)$$ How long does it take in years $$t$$ to double your principal $$P$$ with an interest rate of $$i$$ per annum? $$!2P=P(1+i)^t$$ $$!2=(1+i)^t$$ $$!\log_e […]
While Linux doesn’t have a piece of software that rivals the usability of Pro Tools, you can still do high-quality audio recording with Ardour DAW, a professional digital audio workstation. written for linux/osx. Also, you can use your linux machine as a virtual synthesiser by using VST instruments and recording directly into Ardour DAW. Currently, […]
