Using DSP and ST’s Tune software to compensate for a flatter response on speakers discussed in this app note from ST Microelectronics. Link here (PDF) The application note describes how to measure and analyze the performance of a loudspeaker and how to compensate the frequency response using the ST Speaker Tune software, a tool available […]

Open hardware DSP platform
Open source hardware digital signal processing platform from Paul Janicki: The open hardware DSP platform is a range of small boards that can be plugged together to give you a flexible platform for processing all sorts of audio signals. If you want a simple crossover, a custom USB soundcard and headphone amp, or a fully fledged […]
Review: ADSP-BF592 EZ Lite Kit
Sebastian writes, “Here’s my review of the ADSP-BF592 EZ Lite Kit. Quite an interesting board for people trying to get into DSPs.” Via the contact form.
Developing FFT applications with low-power microcontrollers
Squank provided some links for developers who’d like to use the Fast Fourier Transform in low-power MCUs. FFT is an algorithm used in DSPs to quickly convert time-based functions to spectrum-based function, and vice versa. Via the forum.
Free online DSP book
Squonk alerts us to a very interesting online resource. California Technical Publishing has posted a complete copy of The Scientist and Engineer’s Guide to Digital Signal Processing by Steven W. Smith, PhD. This 640 page volume covers all aspects of DSP and is both searchable online and downloadable. The site also includes links to software […]
TI eZdsp USB stick dev kit
Joe Britvch writes: Check these out. Nice DSP kit for a good price $55 sale (normal $99). The TI C5535 eZdsp USB Stick Development Kit. On sale until 12-31-11. I just got mine, but I have to put it under the Christmas tree for a week. …or… I could put the empty box there instead! […]
Video: DSP/SDR basics
Here’s Jeri Ellsworth’s latest video, explaining the basics of DSP and SDR for beginners, and how to build a digital direct conversion receiver (SDR) using sampling detectors and FPGA DSP processing. (If you want to skip the silly cat portion of the video, start at 1:25.) The links referred to in the video are below: […]
