dsp

Closed - looking at Octo Research dac8 PRO, paired w. Roon + Convolution or MiniDSP.

So after looking into some depth at room correction SW, I wanted to see how to implement DSP into my system. Initially I looked at various of-the-shelf solutions, but in the end decided to see if I can work something out myself - ultimately audio DSP is just a bit of computing power combined...

I have an integrated streamer/DAC. I want to be able to use a DSP system for room correction before the signal gets to my streamer/DAC, hopefully directly from my router. I know that ROON, which I'm using, has DSP capability, but it looks fair hard to get properly setup. Are there any devices...

Given all of the attention headphones are receiving here as of late, I thought this might be of interest. It's merely a press release, though, and light on details: https://www.dirac.com/news/2020/6/30/dirac-and-klipsch-collaborate-to-pioneer-the-next-generation-of-headphone-audio-performance

In his book "Schiit Happened: The Story of the World's Most Improbable Start-Up" Jason Stoddard mentions work done by Mike Moffat on "First true time domain optimized digital filters, based on math perfected with a U of Iowa Professor Emeritus of Mathematics and a RAND Corp mathematician". In a...

So I listen in a smallish room (Can't change that for a multitude of reasons) with some acoustic issues, nothing too bad, but I'm trying to achieve the best possible sound in this room... ... a friend brought his DSP (Accuphase DG-58) over and we tried it out, and it made a noticeable and...

Hi all, new to the forum but I have been told this was the place to come find no-nonsense advice from people who know the ins and outs of the digital and analogue chain / signal and processing... So here is my situation... I've got a decent Hi-Fi system that I mostly (80%) use for streaming...

Hi, I'm new to this forum and hope you forgive my mistakes. I'm a old audiophile who wants to upgrade his (now) simple system (Oppo BD95 + Pass Labs amp + Magnepan MG 3.3) to multi amping. As everybody says Magnepans should sound better in multiamping (maybe all of the loudspeakers do) and I...

Why are active speaker designs so favorable? Should space be available, why wouldn't you want to have the dac, dsp, and amplification devices be independent of the speaker? This allows for easy upgrades if so desired, as well as more control over the hardware in general; you'll likely choose...

@mitchco Mitch Barnett recently launched his Accurate Sound Calibration Service. Mitch has been a great teacher to many. Mitch is a DSP, low frequency optimization and active loudspeaker enthusiast and evangelist. Mitch has written extensively on this topic which includes a complete guide in...

I often see questions asking for more information about FIR filtering and the pros and cons. I've put together an article describing some DSP, FIR and IIR basics, and applications in audio. https://eclipseaudio.com/fir-filter-guide/ Let me know if you find this helpful, and/or if there's...

I read the following sentence in this The Scientist and Engineer's Guide to Digital Signal Processing By Steven W. Smith which talks about ADC & DACs. "For example, suppose that the ones and zeros are represented by 5 volts and 0 volts, respectively. If 80% of the bits in the data stream are...

I would very much appreciate some input from the wise members of this site on various aspects of implementing and integrating a convolution engine into the Linux audio stack. I'm thinking of members like @Cosmik , @mansr , @pos, @yue or others that may have some experience digging around in the...

I first became seriously interested in purchasing the JBL M2 when I was with @amirm at CEDIA 2015. I heard the Harman demo room and was shocked at the sound quality I heard. The Harman demo at CEDIA is like waiting in line for the Pirates of the Caribbean ride at Disney World with my kids...

It is All Software By Amir Majidimehr [Note: this is an article that was published in the Widescreen Review Magazine] OK, it is not all software but most of it is. What am I talking about? I am talking about video! Yes, video. Please don’t flip the page. Let me explain with a bit of...

DSPs: What They Are and Why They Are Used By, Amir Majidimehr Let’s take a look at the typical spec sheet for an Audio/Video processor, in this case an Anthem D2v: “Two dual-core digital signal processing (DSP) engines, our own DSP design, offer a total of 800 MIPS to allow decoding of the new...
