I previously blogged about my satisfactory experience with Arch Linux installation on a second-hand laptop. Now in this post I’m going to turn that $150 laptop into a kick-ass and sexy Amp and Effect Processor. In fact, we will see how lightweight tendency of Arch Linux helps us to achieve a low latency/high quality playback on a computer that is considered somehow outdated in today’s world. Furthermore, we’re going demonstrate the obvious fact that GNU/Linux has already reached the maturity suitable for (semi-)professional audio needs. The project for myself was a bit of stretch and needed a lot of trial-and-error efforts since I was totally new to the whole idea. However the final result is quite superb and amazing.
