  • Create Studio Quality Sound with YM 2151 and FPGA

    Hello FPGA lovers! Today’s post is about making real studio quality music rather than the monotone buzzers from conventional circuits. FPGAs can be used to create monotone sounds such as beeps by using the right combination of DACs and buzzers. However these devices cannot be used to create studio quality sound that not only plays…

  • How Building a DPLCM To Learn About FPGAs Turned To Be A Possible Business

    First of all, yes, what is a DPLCM? At least I had to look this up. Now, I can tell you that DPLCM stands for Digital Audio Peak Level and Correlation Meter. At this point we have covered the most difficult part. This tutorial is so well explained, the author even tells you why he…

  • Feeling like Barenboim? Check it with your FPGA!

    Today´s article shows how a group of students from Cornell University, created a hardware-software set of tools to develop and composed your own music, the Audio Composer and Conducting Suite (A.C.C.S). This virtual conducting environment platform is capable of inputting the compositions from a video camera and a keyboard or a conductor waving his/her hands…

  • FPGA Audio Visualizer Project

    Embedded Systems Design student Zhemao and his class group have been working on an FPGA FFT audio visualizer for their final project. Their design was implemented entirely in VHDL on an Altera DE2 board, the results of which are all bouncy and blue in the above vid. Basically, it’s a hardware audio player that reads…

  • User Created Audio Wing For Papilio

    Hi! We’re back from a nice, much-needed holiday break! We hope your holidays were wonderful for you and your families as well. We’ve got a great wing project here to show you, courtesy of JR from JR’s EE Blog, who has created his own audio wing for the Papilio hardware. JR writes, “For a while…
